East Fork Patrick Bayou

The collected soil sample that I have provided was obtained at the coordinates 29.7238200, -95.1137860 on August 28, 2018 at 12:41PM on a sunny day. The collected sample was taken from the East Fork Patrick Bayou nearby the Buffalo Bayou. The sample was retrieved from an 8-12 inch hole along the bank of the bayou. For week 0, 1.05g of the sample is initially inoculated into an enriched media then for week 1-5 200µL of the previous week’s inoculation culture is added to separate minimal media tubes containing Carbon Selective Media with Paraoxon, Carbon Selective Media with Methyl Parathion, Sulfur Selective Media with Paraoxon, and Sulfur Selective Media with Methyl Parathion. The best indicator for the metabolism of pesticides is then inoculated onto the enriched media for bacteria revitalization then 100μL of the enriched media with bacteria is plated onto a minimal media with MP. The plated sample is then analyzed to confirm that the bacteria is able to tolerate the Methyl Parathion compounds, but not degrade it.

Matthew Joseph Buffalo Bayou Sample

After 5 weeks of testing by progressively diluting the bacteria sample in SSM (Sulfur selective media) and CSM (Carbon Selective media) in both Methyl Parathion and Paraoxon condition it was determined what type organophosphatase activity is found in this bacteria sample after growth in a media rich dish. SSM consistently had more turbidity than the CSM (Carbon selective media) , but only the PX (paraoxon) samples ever had a breakdown to form the yellow color p-nitrophenol product in both, turbidity or no; MP, or Methyl Parathion media NEVER had yellow coloration. This trend stayed throughout, but eventually only the CSM had a yellow color in the 5th week trial with almost no turbidity in any sample. The final trial's SSM PX should still have had a yellow color, but it may have been due to a too great dilution of the soil bacteria by this point that it could not break down the Paraoxon, whereas the CSM-PX had just enough to break down the Paraoxon. However, my bacteria in particular grew best on an SSM based on turbidity consistently staying higher in the SSM tubes. This means that it is a bacteria that breaks down Paraoxon in order to obtain its sulfur or carbon products; the slightly higher level of turbidity in the SSM media throughout the 5 weeks may indicate the bacteria prefers sulfur for growth.

Gabriel General Sample 1

Soil collected from the banks of McGovern Lake outside of the Houston Zoo.

Jessica Zhang - Soil Sample Collection

Very tiny colonies grew on the agar (~8478), but there was no evidence of Px hydrolysis based on the edges of the bacterial colonies. This means that the bacteria can tolerate the Paraoxon pesticide, but not degrade it.

Ayesha Jamal Soil Sample

The soil sample was taken taken from a local park located in SugarLand. A 8-10 feet hole was dug into the ground and a mixture of wet and dry soil was collected in put into the soil collection tube. Over the course of 5 weeks it was noted that the Sulfur Selective Media with the Paraoxon was the best at showing pesticide degradation in bacteria. It was noted in week 4 and week 5 of the experiment that the the SSM+PX tube turned orange then, burnt orange. In the agar plate, it was noted that the PX resulted in two types of bacteria, the larger bacteria around the outside was able to hydrolyze and the bacteria towards the center was only able to tolerate the paraoxon.

Arthur Storey Park

There was growth on the plate and few halos, so it is deduced that the bacteria is able to tolerate the pesticide and not necessarily degrade it. This could be evidence that a degrading bacteria was missed along the process.

Laredo Tx, close to river soil sample

This sample was collected from the nearby shore of Rio Grande, the main river that divides the US with Mexico along Texas. It is noted that a significant amount of contaminants run down this river, making it a very suitable place for data collection. The sample was taken from the US side in a nearby zone close to the international Bridge Juarez Lincoln. During the incubation and transferring process of 5 weeks, the sample displayed increased activity in Paraoxon CSM enriched media with a noticeable yellow coloration, whereas the rest of the tubes did not show any activity and progressively faded into a complete clear coloration. After plating and growth the whole plate was completely covered and made colony count not possible, however prominent white/yellow colonies can be seen which are approximately 200. These colonies are possible zones of hydrolysis of bacteria that is expressing an OPH gene.

An unofficial count of the colonies yields an estimation of about 79 total colonies, with 51 OP degrading colonies, and 28 OP tolerant colonies.
