To our surprise, there were some pairs (P.p + R.j) living well in the same tube and also there were some pairs we were not sure. It seemed that P.putida KT2440 was the dominant bacterium when it was co-cultured with others. We were thinking about limiting its growth by control ingredients in different media.

            <p>The 1KB CSS Grid is a simplified grid system and is one of many dozens of different grids available. I started using a personal variant of this grid system recently because it seemed like a very simple code-base to understand. A common complaint about CSS grids is that they require classes in the markup that aren't much different that simply hard-coding widths in a style attribute. Of course SASS can help remove that complaint and makes grids even more flexible. Here's a tour of the 1KB CSS Grid, modified to suit my tastes and rewritten in SASS.

                  <p>The above CSS is very similar to the <a href="http://www.usabilitypost.com/2009/05/29/the-1kb-css-grid-part-1/">original source</a> with a few stylistic differences (dashes instead of underscores) and the removal of the <code>overflow: hidden</code>
+
clearfix hack and <a href="http://haslayout.net/css/Double-Margin-Bug">IE6 hacks</a>. My intention is to use the grid with <a href="http://html5boilerplate.com/">HTML5 Boilerplate</a> which has a better clearfix built-in (<a href="http://www.yuiblog.com/blog/2010/09/27/clearfix-reloaded-overflowhidden-demystified/"><code>overflow: hidden</code> isn't appealing</a> as a clearfix hack). I've also chosen to <a href="http://windowsteamblog.com/ie/b/ie/archive/2010/09/01/internet-explorer-usage-share-in-august.aspx">remove IE6</a> from my list of supported browsers for any project that doesn't require it.

Above is a typical page using the new HTML5 container tags and based on the <a href="https://github.com/paulirish/html5-boilerplate/blob/master/index.html">example HTML5 Boilerplate markup</a>. This example is shown with hard-coded class names in the HTML. As expected, there's a page wrapper (<code>#container</code>
 
), <code>header</code>
 
, <code>#main</code>
 
and <code>footer</code>
 
containers, and some columns in the main area. This page would create a typical 2 column layout (<code>#left-column</code>
 
and <code>#main-column</code>
 
). The <code>#main-column</code>
 
, as shown, has a <code>.hero</code>
 
area that spans the full width and a content area is further sub-divided into 2 columns (<code>#content</code>
 
and <code>#right-column</code>
 
).
 
</p>
 
<p>
 
On a typical site, the <code>header</code>
 
and <code>footer</code>
 
would probably contain their own columns and rows. The <code>.hero</code>
 
is used for promotional space at the top of content. This is a typical design choice and might contain a banner or a slideshow or some introductory copy.
 
</p>
 
<p>
 
Personally I find the inclusion of the class names in the markup to be a little ugly. The most offensive part is the <code>grid-3</code>
 
and <code>grid-6</code>
 
, etc. This is barely different than hard-coding the width with an inline style. I prefer to use SASS mixins to remove those class names from the markup altogether and control it directly from the CSS.

Writing the same thing in SASS opens up a world of possibilities. Using <a href="http://sass-lang.com/docs/yardoc/file.SASS_REFERENCE.html#defining_a_mixin">mixins</a> allows the column measurements to be easily changed and opens up the possibility of removing the extra class names from the markup. This SASS file was used to generate the CSS at the top of the article.

+
<ul>

<li>

<code>$column-width: 60px;</code>

is the width of a sinlge column

<li>

<code>$gutter-width: 20px;</code>
+
is the space between two columns

<h3 id="grid-mixins">Grid Mixins</h3>
+
<p>
+
<code>grid</code>
+
and <code>grid-plus</code>
+
are simply used for setting a width on a column. <code>grid-plus</code>
+
can be used to account for padding or otherwise arbitrarily altering the standard column width. This is especially useful when dealing with designers that like grids but like violating them even more.

<b><h1 style="font-size:108%">&nbsp;&nbsp;Aug.7th</b></h1>
The example above shows 3 equivalent ways to specify a 6-column-wide column. The shortcut <code>grid-column</code>
+
<div style="padding-left:32px;">For each pair, we checked the bacterial concentration at OD_600 and detected the concentration of TPA by UV at Abs_242.According to results of the UV tests, if R.j existed, whatever the strategy was, the concentration of TPA would significantly decrease. Especially for pairs R.j+P.p and R.j + B.s, results showed greater reductions in the concentration of TPA compared with control group.</div>
mixin makes it easy to create a standard column. But in the case where a column might require <code>border</code>
+
<br/>
or <code>padding</code>
+
, the <code>grid-plus</code>
+
mixin can be used to account for the difference.
+
</p>
+
<ul>
+
<li>
+
<code>@include grid(&lt;number&gt;);</code>
+
is for column widths
+
<ul>
+
<li>
+
<code>@include grid-plus(&lt;number&gt;, &lt;length&gt;);</code>
+
is for columns that need a non-standard width
+
</li>
+
</ul>
+
</li>
+
<li>
+
<code>@include grid-column;</code>
+
is for floating columns
+
<ul>
+
<li>
+
<code>@include grid-column(&lt;number&gt;);</code>
+
is a shortcut, the same as calling <code>grid(&lt;number&gt;)</code>
+
and <code>grid-column</code>
+
consecutively
+
</li>
+
<li>
+
<code>@include grid-column-empty(&lt;number&gt;, &lt;position&gt;);</code>
+
adds margin to create empty space either before or after the column
+
</li>
+
</ul>
+
</li>
+
<li>
+
<code>@include grid-row;</code>
+
is a column container
+
</li>
+
<li>
+
<code>@include grid-page;</code>
+
is the main page wrapper with a full width and is horizontally centered
+
<ul>
+
<li>
+
<code>@include grid-page(&lt;number&gt;);</code>
+
creates a page container that is less than the default page width; useful for modal pop-ups

</li>
+
</ul>

<h2 id="basic-example-using-sass">Basic Example Using SASS</h2>
+
<p>
+
Using the ID's and class names already in the markup, it's possible to utilize the mixins that were created earlier to achieve the exact same effect. I typically do this in a layout file that contains all of the column layouts for the various templates in the site.

<h4>To Be Clear</h4>
 
<ul>
 
<li>
 
<code>#container</code>
 
is specified as a <code>grid-page</code>
 
</li>
 
<li>
 
<code>header</code>
 
, <code>#main</code>
 
and <code>footer</code>
 
are set up as <code>grid-row(true)</code>
 
<ul>
 
<li>
 
This essentially applies <code>.clearfix</code>
 
to those container
 
</li>
 
<li>
 
<code>grid-row(true)</code>
 
is used for rows contained directly within a <code>grid-page</code>
 
which ommits the negative margins that would otherwise be applied.
 
</li>
 
</ul>
 
</li>
 
<li>
 
<code>#left-column</code>
 
and <code>#right column</code>
 
are specified as 3-columns wide
 
</li>
 
<li>
 
The <code>#main-column</code>
 
is 9 columns wide. More importantly, all <code>section</code>
 
tags are specified as <code>grid-row</code>
 
, allowing them to contain columns.
 
</li>
 
<li>
 
The <code>#content</code>
 
column is 6 columns wide.
 
</li>
 
</ul>
 
<p>
 
From the above example it should be clear how to use mixins to apply the grid styles directly through CSS without needing to hard-code the grid related class names into the markup.

Notes for Bacterial Consortium

Week1(7/24/2016-7/30/2016)

  • Optimization of Culture Conditions


      Jul.26th

    Prepare M9 medium with TPA and culture Pseudomonas putida KT2440 at 30℃ & 200 rpm, checked the bacterial concentration at OD600.

      Jul.27th

    1.Extract 10 ml LB medium to 5 test tubes and add 0μl, 50μl,, 100μl,, 250μl,, 500μl EG to them, respectively.
    2.Add 5μl bacteria solution of Pseudomonas putida KT2440 to five test tubes above.
    3.Culture them at 30℃ & 200 rpm, checked the bacterial concentration at OD600.

      Jul.28th

    Add 6g TPA, 2.9gNaOH and 1.2g glucose to M9 medium, and culture them in the improved M9 medium and M9 medium of Jul.26 at 30℃ & 200 rpm, checked the bacterial concentration at OD600 and detected the concentration of TPA by UV at OD242.

      Jul.30th

    Cultured different bacteria in M9 medium with sodium terephthalate and different concentration of glucose at 30℃ & 200 rpm, checked the bacterial concentration at OD600 and detected the concentration of TPA by UV at OD242.

    Week2(7/31/2016-8/6/2016)

  • Optimization of Culture Conditions


      Jul.31th

    Cultured Rhodococcus jostii RHA1 in M9 medium with sodium terephthalate and glucose at 30℃ & 200 rpm, checked the bacterial concentration at OD600 and detected the concentration of TPA by UV at OD242.

      Aug.1th

    Cultured Rhodococcus jostii RHA1 in W medium with sodium terephthalate and glucose at 30℃ & 200 rpm, checked the bacterial concentration at OD600 and detected the concentration of TPA by UV at OD242.

      Aug.2th

    Cultured Pseudomonas putida KT2440 in W medium with sodium terephthalate and glucose at 30℃ & 200 rpm, checked the bacterial concentration at OD600 and detected the concentration of TPA by UV at OD242.

      Aug.3th

    Cultured Pseudomonas putida KT2440 , Rhodococcus jostii RHA1 , Pseudomonas putida KT2440 and Rhodococcus jostii RHA1in W medium with sodium terephthalate and glucose at 30℃ & 200 rpm, checked the bacterial concentration at OD600 and detected the concentration of TPA by UV at OD242.

      Aug.4th

            Observed the growth of 1-day pre-cultured bacteria in LB at 30℃:
    All above were kept culturing for one more day and were checked on the next day. The next step was to explore the optimal condition for each bacterium and to co-culture each teo of them to see whether the consortium could work well.

    The most probable pairs:
    1. P.putida KT2440 + R.jostii RHA1;
    2. B.subtilis 168 + R.jostii RHA1;
    3. B.subtills 168 + P.putida KT2440;
    4. R.jostii RHA1 + Y.lipolytia;
    5. P.putida KT2440 + Y.lipolytia;
    6. E.coli(RFP) + Y.lipolytia.
