For the diacetyl volatile test, 6 sets of the tests were performed using different concentrations of diacetyl. Each set was repeated twice to obtain an average response index to maximize accuracy. For 1x concentration of diacetyl, the average index was +0.96. At 1/10x concentration, the average index dropped slightly to +0.84. From then on, it dropped dramatically to +0.27 at 1/100x concentration, then to +0.17 at 1/1000x concentration. At 1/10000x concentration, the index was at +0.05. But it rose slightly to +0.06 at 1/100000x concentration.<br><br>
 +
 
 +
All the response indices collected were positive. This suggests that diacetyl is a volatile attractant. The high index recorded at 1x concentration shows that diacetyl is the most potent attractant. However, as evidenced by data from 1x concentration to 1/1000x concentration, when concentration is lowered, its potency as an attractant decreases. It can be concluded, hence, that the potency of diacetyl as an attractant is directly proportionate to its concentration up till 1/1000x concentration. The slight rise in average index at 1/100000x concentration suggests that 1/100000x diacetyl is a slightly stronger attractant than 1/10000x diacetyl. <br><br>
 +
 
 +
As a result, this assay proves that pure diacetyl attracts C. elegans and can be utilized in our experiments as a positive control for attractant.<br><br>

For the cinnamaldehyde volatile test, 6 sets of the tests were performed using different concentrations of cinnamaldehyde. Each set was repeated thrice this time. The results were processed to produce an average response index. For 1x concentration of cinnamaldehyde, an average index of -0.81 was recorded. The index then fluctuates slightly to -0.80 at 1/10x concentration and to -0.82 at 1/100x concentration subsequently. The index then drops to -0.50 at 1/1000x concentration. The index decreases dramatically to -0.13 at 1/100000x concentration. It finally decreases to -0.10 at 1/10000x concentration.<br><br>
 +
 
 +
All the indices collected were negative. This suggests that cinnamaldehyde is a volatile repellant. The similarly high negative indices at 1x concentration to 1/100x concentration show that cinnamaldehyde is a strong repellant. The difference in indices is only 0.01, hence, it suggests that the differing concentrations have little to do with the repelling effect of cinnamaldehyde. The negative indices then decrease along with concentration as evidenced by the data from 1/1000x concentration 1/100000x concentration. This shows that the repelling effect is directly proportionate to the concentration of the cinnamaldehyde.

For the phenylpyruvic acid droplet test, 6 sets of the tests were performed using different concentrations of chemical ranging from 1x to 1/100000x. Each set was repeated thrice for a constant result. The results were processed to produce an average responsive index. For 1x concentration of phenylpyruvic acid, an average index of +0.34 was recorded. The index then declines slightly to +0.31 at 1/10x concentration and to +0.28 at 1/100x concentration subsequently. The index then drops to +0.18 at 1/1000x concentration. The index further decreases to +0.04 at 1/100000x concentration. It finally decreases to -0.01 at 1/10000x concentration.<br><br>
 +
 
 +
All response index from the phenylpyruvic acid droplet tests are positive except at concentration 1/100000x with index of -0.01. The indices obtained at concentrations 1/1000x, 1/10000x and 1/100000x are too close to 0, that is a neutral substance. Therefore the data obtained from the three lowest concentrations in this test is ignored and cannot give a conclusion. As the response indices at 1x, 1/10x and 1/100 concentration phenylpyruvic acid are positive and are indicate a relatively significant attractiveness of C.elegans, we would suggest phenylpyruvic acid is a mild attractant to C.elegans. Also, at the above concentrations, the indices decreases consequently with intervals 0.03 and then drop significantly onwards. Therefore we have to use concentrations between 1x and 1/100x of phenylpyruvic acid in further experiments to obtain meaningful results. The indices decrease as the concentration of phenylpyruvic acid decrease, showing the attracting effect is directly proportional to the concentration of phenylpyruvic acid.
 +
<br><br>
 +
 
 +
To conclude, this assay proves that pure phenylpyruvic acid attracts C. elegans and can be used for our experiments.

We are only able to clone plasmid with phenylpyruvic acid production enabling gene. We used transformed bacteria containing the composite part to produce synthetic PA. The assay is being repeated twice. Its average response index was +0.83. Comparatively, the average index of transformed bacteria with backbone-only plasmid was +0.63, while it is known that bacteria attracts C. elegans as a food source, the data proves that our bacteria indeed has potency as an attractant that is independent of its nature as a food source. Hence, our bacteria are attractants to C. elegans in themselves. The transformed bacteria had a higher index than PA, suggesting that the bacteria are stronger attractants. However, the bacteria still have a lower index than diacetyl.<br><br>

As an overall comparison of pure chemicals, the response index for diacetyl was 0.96, which is tested to be a strong attractant and has been used as a positive control for attractant. Water was used as a negative control and obtained an index of +0.07. Phenylpyruvic acid, having the lowest positive responsive index of +0.34 is suggested to be a mild attractant. On the other hand, pure cinnamaldehyde had -0.81 response index. It was the only chemical that had a negative index, suggesting that it is the only repellant in our range of chemicals. It is a strong repellant as evidence with its obtaining a highly negative index. The index obtained from the bacteria synthesized PA droplet test is higher than that obtained from backbone-only plasmid bacteria. This suggests the transformed bacteria has performed our desired effect.<br><br>

For our experiments, we did 2 types of volatile tests: one for diacetyl and another for cinnamaldehyde.

Positive Control for Attractant



For the diacetyl volatile test, 6 sets of the tests were performed using different concentrations of diacetyl. Each set was repeated twice to obtain an average response index to maximize accuracy. For 1x concentration of diacetyl, the average index was +0.96. At 1/10x concentration, the average index dropped slightly to +0.84. From then on, it dropped dramatically to +0.27 at 1/100x concentration, then to +0.17 at 1/1000x concentration. At 1/10000x concentration, the index was at +0.05. But it rose slightly to +0.06 at 1/100000x concentration.

All the response indices collected were positive. This suggests that diacetyl is a volatile attractant. The high index recorded at 1x concentration shows that diacetyl is the most potent attractant. However, as evidenced by data from 1x concentration to 1/1000x concentration, when concentration is lowered, its potency as an attractant decreases. It can be concluded, hence, that the potency of diacetyl as an attractant is directly proportionate to its concentration up till 1/1000x concentration. The slight rise in average index at 1/100000x concentration suggests that 1/100000x diacetyl is a slightly stronger attractant than 1/10000x diacetyl.

As a result, this assay proves that pure diacetyl attracts C. elegans and can be utilized in our experiments as a positive control for attractant.

Negative control

The average response index of water is taken as +0.07, obtained among 6 repeated assays. This indicates water is a neutral chemical towards C.elegans. considering this, we use water as a negative control for onwards experiments.

CA



For the cinnamaldehyde volatile test, 6 sets of the tests were performed using different concentrations of cinnamaldehyde. Each set was repeated thrice this time. The results were processed to produce an average response index. For 1x concentration of cinnamaldehyde, an average index of -0.81 was recorded. The index then fluctuates slightly to -0.80 at 1/10x concentration and to -0.82 at 1/100x concentration subsequently. The index then drops to -0.50 at 1/1000x concentration. The index decreases dramatically to -0.13 at 1/100000x concentration. It finally decreases to -0.10 at 1/10000x concentration.

All the indices collected were negative. This suggests that cinnamaldehyde is a volatile repellant. The similarly high negative indices at 1x concentration to 1/100x concentration show that cinnamaldehyde is a strong repellant. The difference in indices is only 0.01, hence, it suggests that the differing concentrations have little to do with the repelling effect of cinnamaldehyde. The negative indices then decrease along with concentration as evidenced by the data from 1/1000x concentration 1/100000x concentration. This shows that the repelling effect is directly proportionate to the concentration of the cinnamaldehyde.

As a result, the assay proves that pure cinnamaldehyde repels C. elegans and can be used for our experiments.

Phenylpyruvic Acid



For the phenylpyruvic acid droplet test, 6 sets of the tests were performed using different concentrations of chemical ranging from 1x to 1/100000x. Each set was repeated thrice for a constant result. The results were processed to produce an average responsive index. For 1x concentration of phenylpyruvic acid, an average index of +0.34 was recorded. The index then declines slightly to +0.31 at 1/10x concentration and to +0.28 at 1/100x concentration subsequently. The index then drops to +0.18 at 1/1000x concentration. The index further decreases to +0.04 at 1/100000x concentration. It finally decreases to -0.01 at 1/10000x concentration.

All response index from the phenylpyruvic acid droplet tests are positive except at concentration 1/100000x with index of -0.01. The indices obtained at concentrations 1/1000x, 1/10000x and 1/100000x are too close to 0, that is a neutral substance. Therefore the data obtained from the three lowest concentrations in this test is ignored and cannot give a conclusion. As the response indices at 1x, 1/10x and 1/100 concentration phenylpyruvic acid are positive and are indicate a relatively significant attractiveness of C.elegans, we would suggest phenylpyruvic acid is a mild attractant to C.elegans. Also, at the above concentrations, the indices decreases consequently with intervals 0.03 and then drop significantly onwards. Therefore we have to use concentrations between 1x and 1/100x of phenylpyruvic acid in further experiments to obtain meaningful results. The indices decrease as the concentration of phenylpyruvic acid decrease, showing the attracting effect is directly proportional to the concentration of phenylpyruvic acid.

To conclude, this assay proves that pure phenylpyruvic acid attracts C. elegans and can be used for our experiments.

Bacteria synthesized chemicals



We are only able to clone plasmid with phenylpyruvic acid production enabling gene. We used transformed bacteria containing the composite part to produce synthetic PA. The assay is being repeated twice. Its average response index was +0.83. Comparatively, the average index of transformed bacteria with backbone-only plasmid was +0.63, while it is known that bacteria attracts C. elegans as a food source, the data proves that our bacteria indeed has potency as an attractant that is independent of its nature as a food source. Hence, our bacteria are attractants to C. elegans in themselves. The transformed bacteria had a higher index than PA, suggesting that the bacteria are stronger attractants. However, the bacteria still have a lower index than diacetyl.

Overall Comparison



As an overall comparison of pure chemicals, the response index for diacetyl was 0.96, which is tested to be a strong attractant and has been used as a positive control for attractant. Water was used as a negative control and obtained an index of +0.07. Phenylpyruvic acid, having the lowest positive responsive index of +0.34 is suggested to be a mild attractant. On the other hand, pure cinnamaldehyde had -0.81 response index. It was the only chemical that had a negative index, suggesting that it is the only repellant in our range of chemicals. It is a strong repellant as evidence with its obtaining a highly negative index. The index obtained from the bacteria synthesized PA droplet test is higher than that obtained from backbone-only plasmid bacteria. This suggests the transformed bacteria has performed our desired effect.
