+ | - This week passes restreaking colonies to yield pure colonies and trying to find the correct transformants through by purifying the plasmids and subjecting it to analytical digestion. So far no luck! | ||

Chris, our supervisor, brought us in contact with Martin and Erik, two professors from DTU Nano and Elektro. Our university is running a new project course in January where 1st semester students ferment their own cultures and build devices to monitor growth. They built a measuring chamber and a simple circuit, reading the voltage over the photodiode with a multimeter. Isn’t there a way to do all this using an Arduino? We set a meeting for next week.

Got review literatures and questions and answers sessions from DTU Biosustain. We are added to DTU Biosustain’s online help platform in slack. And got many answers from DTU Biosustain experts, both online and in person at helpdesk sessions. Model is validated using Cameo with published and unpublished data from DTU Bioengineering, model is considered good enough to simulate general trends from substrate constraints. Tried to move on to strain design investigation using gene KO. Attempted but failed at making OptGene work. Returned no results. Attempted but failed at plotting fluxes on Escher due to reaction and metabolite IDs mismatch and the lack of <i>Y. lipolytica</i> metabolism maps. Same problem with KEGG maps, we do not have the right IDs to plot fluxes. It would be too time consuming to find the IDs or build a map on Escher ourselves, solution pending.</p> | ||

In this section you can follow our progress in the different subgroups week for week. Some weeks are quite, while some weeks are very hectic - especially right up to the wiki freeze.
June
"Every great love starts with a great story..."
Nicholas Sparks, The Notebook
Week 1 (May 30 - June 5)
Wetlab
Yarowia lipolytica PO1f Δku70 was obtained from Cory M. Schwartz, cultivated and freeze stocked for future use.

Hardware
Our Arduino starter kits arrived! Make an LED blink. That’s how it begins.
Week 2 (June 6 - June 12)
Wetlab
Molecular Toolbox
![](https://static.igem.org/mediawiki/2016/a/a7/T--DTU-Denmark--pex10.png)
CRISPR-Cas9 induced PEX10 knockout
Y. lipolytica PO1f genome sequence was annotated and protospacer for targeting PEX10 was designed and ordered from IDT. Protospacer for Gibson Assembly with CRISPRyl plasmid (Addgene plasmid #70007) SCR1'- tRNAGly (bold), Protospacer (underlined), sgRNA (italic)
5'-GGGTCGGCGCAGGTTGACGTGTACAAGGAGGAGCTGGAGAGTTTTAGAGCTAGAAATAGC-3'
Oligos designed to amplify a 1kb region upstream and downstream PEX10 and anneal together by fusion PCR were also ordered from IDT.![](https://static.igem.org/mediawiki/2016/5/57/T--DTU-Denmark--ura3.png)
CRISPR-Cas9 induced URA3 insertion
The Y. lipolytica PO1f genome sequence was annotated and uploaded to Benchling for sgRNA design. sgRNAs targeting the SUC2 gene were designed. Primers were designed that amplify the functional URA3 gene including 1 kb upstream and downstream flanking regions.
![](https://static.igem.org/mediawiki/2016/a/ac/T--DTU-Denmark--pSB1A8YL.png)
pSB1A8YL
Ran a bunch of PCRs to amplify the pUC19 part of our plasmid, but it’s not working - nothing but smear. Tried to transform the pUC19 plasmid into Escherichia coli.
![](https://static.igem.org/mediawiki/2016/7/79/T--DTU-Denmark--substrate.png)
Substrates
We did an initial experiment determining the full growth cycle of Y. lipolytica W29. This will be used to plan and time the following growth experiments. Waste glycerol from the industrial biodiesel producer DAKA is acquired for late screening.
Compute

Hardware
We started building light sensors using photoresistors. Shortlisting ideas for our final project: - A microtiter plate reader - Hack a printer to build a membrane homogenizer - Chemostat bioreactor
Week 3 (June 13 - June 19)
Wetlab
Molecular Toolbox
![](https://static.igem.org/mediawiki/2016/a/a7/T--DTU-Denmark--pex10.png)
CRISPR-Cas9 induced PEX10 knockout
Genomic DNA from Y. lipolytica PO1f Δku70 and Y. lipolytica W29 was purified. PEX10 flanking regions were successfully amplified from Y. lipolytica PO1f Δku70.
![](https://static.igem.org/mediawiki/2016/5/57/T--DTU-Denmark--ura3.png)
CRISPR-Cas9 induced URA3 insertion
Genomic DNA from Y. lipolytica PO1f Δku70 and Y. lipolytica W29 was purified. PCR attempts to amplify URA3 and flanks failed. sgRNAs targeting the SUC2 gene were hybridized.
![](https://static.igem.org/mediawiki/2016/a/ac/T--DTU-Denmark--pSB1A8YL.png)
pSB1A8YL
Purified the plasmid from the transformants and use this as template for PCR, although it’s still not giving any bands.
![](https://static.igem.org/mediawiki/2016/7/79/T--DTU-Denmark--substrate.png)
Substrates
We did initial growth experiments on minimal media with an array of different carbon sources. This experiment was discarded due to lack of repeats and wrong vitamin solution for minimal media. Waste from canola oil production by Grønninggaard is acquired. Molasses from Dansukker sugar production is acquired.
Compute

Hardware
Exploring the Arduino IDE and all the electronic components we ordered. There is so much to learn.
Week 4 (June 20 - June 26)
Wetlab
Molecular Toolbox
![](https://static.igem.org/mediawiki/2016/a/a7/T--DTU-Denmark--pex10.png)
CRISPR-Cas9 induced URA3 insertion
PCR attempts to amplify URA3 + flanks from Y. lipolytica W29 genomic DNA failed. New primers were ordered.
![](https://static.igem.org/mediawiki/2016/a/ac/T--DTU-Denmark--pSB1A8YL.png)
pSB1A8YL
We realized that the name of the primer had been mixed up! Now that the right primers are used, we get excellent bands on our gel… Guess you have to make the stupid mistakes in the beginning? The gBlock containing the other part of the plasmid also arrived. This also gives excellent bands on the gel when amplifying it by PCR. Ran the first USER and transformed E. coli cells. The transformants were left on the bench over the weekend
![](https://static.igem.org/mediawiki/2016/7/79/T--DTU-Denmark--substrate.png)
Substrates
We have data from the first successful growth experiment. Starch, Xylose, Arabinose, Maltose and Lactose are not suitable for Y. lipolytica fermentation. This will be repeated next week to make sure. Waste glycerol from the industrial biodiesel producer Perstop is acquired.

CRISPR-Cas9 induced PEX10 knockout
Received CRISPRyl plasmid (Addgene plasmid #70007). The procedure from Addgene was followed.
![](https://static.igem.org/mediawiki/2016/5/57/T--DTU-Denmark--ura3.png)
CRISPR-Cas9 induced URA3 insertion
Successful amplification of URA3 + flanks from Y. lipolytica W29 genomic DNA. Because of low quality of the genomic DNA, the initial PCR product was taken for further amplification. Received CRISPRyl plasmid (Addgene plasmid #70007). The procedure from Addgene was followed.

pSB1A8YL
YES, colonies! Colonies were picked and used for colony PCR, but it was not successful. We’ll just have to crank on! - Colonies from the same plates were re streaked and plasmids were purified from the resulting colonies. - Restriction analysis yielded weird bands. - This week passes restreaking colonies to yield pure colonies and trying to find the correct transformants through by purifying the plasmids and subjecting it to analytical digestion. So far no luck!
![](https://static.igem.org/mediawiki/2016/7/79/T--DTU-Denmark--substrate.png)
Substrates
Repeated positive results with growth on glucose, glycerol, fructose, sucrose and oil. Y. lipolytica should not be able to grow on sucrose. The experiments on starch, xylose, arabinose, Maltose and Lactose are still negative for Y. lipolytica. Waste glycerol from the industrial biodiesel producer Emmelev is acquired.
Compute
![](https://static.igem.org/mediawiki/2016/d/d8/T--DTU-Denmark--modeling.png)
Genome Scale Modeling
Planning of Genome-scale modelling strategies began, decided to attempt media optimization using phenotype phase plane, team starts to research and learn FBA for GSM.
![](https://static.igem.org/mediawiki/2016/1/1f/T--DTU-Denmark--software.png)
Software
Initiation of task by designing the workflow needed to achieve the final purpose of the software. Tasks agreed upon discussion : script in python , number and format proxy of the input files needed , restriction site implementation , development GUI, gui library for python (tkinter)

pSB1A8YL
YES! Finally a construct that seems to have the correct length! Both the analytical digestion and PCRs seems to confirm our construct. The construct was also sent for sequencing. We spent some time trying to figure out how to test the plasmid. We ended up retrieving the BBa_K592009, BBa_K592010, BBa_E1010 and BBa_J23110 parts from the distribution kit, and pair them. The idea is that if we are able to make a construct in our backbone, we should see a visual output. Unfortunately we were not able to retrieve the BBa_K592010 from the distribution kit, and it was decided to leave this for now.
![](https://static.igem.org/mediawiki/2016/7/79/T--DTU-Denmark--substrate.png)
Substrates
Contamination of experiments was determined with microscopy. Might come from the minimal media being contaminated. First test on complex glycerol based media. Y. lipolytica seems to grow better than Saccharomyces cerevisiae. The growth form on different C-sources is analysed with microscopi. There seem to be different amounts of planktonic and filamentous growth depending on energy source.
Compute
![](https://static.igem.org/mediawiki/2016/1/1f/T--DTU-Denmark--software.png)
Software
Implementation of algorithm already started. The script is being written in Python3 with the intention to be easily modifiable so no external packages are needed although Anaconda is being used.
Week 7 (July 11 - July 17)
Wetlab
Molecular Toolbox
![](https://static.igem.org/mediawiki/2016/a/a7/T--DTU-Denmark--pex10.png)
CRISPR-Cas9 induced PEX10 knockout
The assembled CRISPRyl plasmid with PEX10 protospacers was transformed in competent E. coli DH5α cells. Purification of assembled CRISPRyl plasmid with Pex10 protospacers. The assembled CRISPRyl plasmid with PEX10 protospacers was digested with AvrII to test if the PEX10 protospacer was inserted. The digestion was successful and showed no cutting by AvrII indicating correct insertion of PEX10 protospacers. First attempt of transformation with CRISPRyl plasmid with PEX10 protospacers in Yarowia lipolytica PO1f Δku70. The transformation was unsuccessful. There was growth all over the plates.
![](https://static.igem.org/mediawiki/2016/5/57/T--DTU-Denmark--ura3.png)
CRISPR-Cas9 induced URA3 insertion
Confirmation of successful Gibson assembly through restriction analysis. First (unsuccessful) transformation of pCRISPRyl and pCRISPRyl+sgRNAs into Yarowia lipolytica PO1f Δku70.
Products
![](https://static.igem.org/mediawiki/2016/e/e2/T--DTU-Denmark--betacarotene.png)
Beta-Carotene
BioBricks BBa_K152005 (crtE,crtI,crtYB,gfp) and BBa_K530002 (crtI) were received from the registry. E. coli with BBa_K152005 could only grow without Ampicilin, so we suspect a problem with the AmpR backbone. We decided not to use this biobrick and instead only work with BBa_K530002, BBa_K530000 and BBa_K530001.

Proinsulin
Designing and ordering synthetic gBlock from IDT encoding TEF1, proinsulin and GFP.

Substrates
Test shows no growth on samples of wastewater from areas contaminated with leftovers of organic molecules from fossil oil. Experiments with glycerol byproduct from Emmelev biodiesel production showed to be contaminated. We investigated where the contaminations could come from and a contaminated pipet seemed to be the source.

Hardware
The library for our LCD Display is commented in Chinese. Shoutout to James for translating. Chris, our supervisor, brought us in contact with Martin and Erik, two professors from DTU Nano and Elektro. Our university is running a new project course in January where 1st semester students ferment their own cultures and build devices to monitor growth. They built a measuring chamber and a simple circuit, reading the voltage over the photodiode with a multimeter. Isn’t there a way to do all this using an Arduino? We set a meeting for next week. Reading about digital to analog conversion(DAC) and the reverse(ADC). Dimming LEDs in the office.

pSB1A8YL
The promoter was paired with the chromoproteins using 3A assembly. Unfortunately, no color was observed even though PCR and analytical digestion showed that the length of the construct are correct.
![](https://static.igem.org/mediawiki/2016/f/f9/T--DTU-Denmark--promoter.png)
Promoters
TEF1 was amplified from gBlock by PCR. SCR1’-tRNA promoter was amplified from the pCRISPRyl plasmid by PCR with primers introducing a base substitution to remove illegal restriction site.

Beta-Carotene
Biobricks BBa_K530000 (crtYB) and BBa_K530001 (crtE) from the distribution kit was successfully obtained. We designed Gibson primers including 5'-CACA-3' upstream of each start codon for assembly of all three genes.
![](https://static.igem.org/mediawiki/2016/a/ad/T--DTU-Denmark--proinsulin.png)
Proinsulin

Genome Scale Modeling
Ben has kickstarted the modeling, by introducing the phenotype phase plane concept to the team, which is an extension to flux-balance analysis. The hope is that it will be possible to find optimal in-flow of various substrates in order to maximize product, in this case beta-carotene. Downloaded first Y. lipolytica model “MODEL1510060001”. Tutorials are studied in Matlab.
![](https://static.igem.org/mediawiki/2016/1/1f/T--DTU-Denmark--software.png)
Software
Script writing is finished. Testing of functionality was initiated in order to find the most “sustainable” solution in terms of resources and the optimization step (reverse-translation) from the desired sequences to protein sequences. Approach decided for main body of script is building and checking the sequences “on the fly” while using as initial files the y_lip.txt (gcn), desired.fsa(protein sequences), ressites.txt(restriction sites).
![](https://static.igem.org/mediawiki/2016/8/8d/T--DTU-Denmark--hardware.png)

Research with regards to distribution and repository of software and compatibility regarding different OS versions. PyInstaller software will be used due to its capability of producing executables for all the known OS, so the user doesn't have to do anything else than just downloading the software.

CRISPR-Cas9 induced PEX10 knockout
Received Y. lipolytica PO1f strain and pIW357, pIW381 and pIW501 from Cory M. Schwartz. pIW501 was digested, and transformations into Y. lipolytica PO1f and PO1f Δku70 was initiated with pIW357, liniar pIW501, pIW357 + linearized pIW501, pIW357 + circular pIW501 and circular pIW501.

CRISPR-Cas9 induced URA3 insertion
Plasmid purification and restriction analysis of pCRISPRyl+sgRNAs and URA3+flanks ligation/transformation. No successful transformants were obtained. This project was discontinued, and another strategy of inserting URA3 in the place of PEX10 is initiated.

pSB1A8YL
Unfortunately the 3A assembly of last week did not work out. We tried again. This time the colony PCR seemed right.

We removed two illegal restriction sites (AgeI and BglII) from BBa_K530001 and BBa_K530002 by site directed mutagenesis. The improved BioBricks were digested to confirm correct removal.

Proinsulin
3A assembly for a) hrGFP+pSB1C3, b) pTEF:hrGFP+pSB1C3, c) pTEF:hrGFP+pSB1A8yl, d) pTEF:CFP+pSB1A8yl. Expected band was observed only for hrGFP+pSB1C3. This construct was used in a new 3A assembly together with pTEF and both pSB1A8yl and pSB1C3, which was successful.

Genome Scale Modeling
Modelling getting more help from DTU Biosustain to set up Cameo on our computers, succeeded, Cameo can now be run without solvers and library errors. Got review literatures and questions and answers sessions from DTU Biosustain. We are added to DTU Biosustain’s online help platform in slack. And got many answers from DTU Biosustain experts, both online and in person at helpdesk sessions. Model is validated using Cameo with published and unpublished data from DTU Bioengineering, model is considered good enough to simulate general trends from substrate constraints. Tried to move on to strain design investigation using gene KO. Attempted but failed at making OptGene work. Returned no results. Attempted but failed at plotting fluxes on Escher due to reaction and metabolite IDs mismatch and the lack of Y. lipolytica metabolism maps. Same problem with KEGG maps, we do not have the right IDs to plot fluxes. It would be too time consuming to find the IDs or build a map on Escher ourselves, solution pending.

CRISPR-Cas9 induced PEX10 knockout
Transformations continues. There is growth in liquid selective media, but colonies are still growing on SC-oleic acid, which they should not be able to if PEX10 has been knocked out. On a successful note, we achieved to insert URA3 by homologous recombination in Yarowia lipolytica PO1f Δku70!

OH NO! The sequencing tells us that the TEF promoter was not inserted! This is going to be a last minute results, if any! 3A assembly was repeated.

We verified the removal of the illegal restriction sites by sequencing. The sequencing results showed a nucleotide substitution in each restriction site corresponding to the ones introduced with the primers.

Proinsulin
Multiple attempts to detect production of proinsulin in Y. lipolytica were preformed with rtPCR, SDS-PAGE and Western Blotting. No protein or mRNA was detected. we suspect that yields are too low, or protein is not folding correctly. Project discontinued.

CRISPR-Cas9 induced PEX10 knockout
We have now observed that the colonies from pIW357 transformation into Y. lipolytica PO1f after SC-leu selection and outgrowth on YPD have different morphologies, a rose like shape, and a pearly shape. In consultation with Cory M. Schwartz we found out, that the pearly colonies are probably colonies with the PEX10 knockouts. We immediately restreaked, and made colony PCR and sent for sequencing. Unfortunately we will not get the final results before after the wiki freeze, but who cares, it finally works!!!

pSB1A8YL
This time the construct seems right! Now only the fluorescence microscopy will tell us if our construct works. Aaaaaaaaand - it does!!!! Little autofluorescence on the negative, and clear, strong GFP signal from Y. lipolytica cells with the construct integrated! Luckily this data came in on the day of the wiki freeze!

Substrates
Both S. cerevisiae and Y. lipolytica show growth on oleic acid, one of the main components in canola oil. When S. cerevisiae can grow on this there must be some other reason it will not grow on canola oil waste. This shows Y. lipolytica to be at growth on complex waste streams.

Final simulations to produce PHPP graphs with fixed axis and simulated gene targets using FSEOF only, instead of KOs, we will use gene amplifications. Success at plotting the gradients of fluxes from FSEOF on to metabolic map created in Cytoscape, directly using the model sbml file with help from supervisor.
