Soil sample collected was at a nearby neighborhood bayou where it experiences frequent flooding, which possibly contributes to the growth of various bacteria. Additionally, this area is predicted to have come into contact with pesticides to certain plantation from growing in the area.
The sample was collected in an area known for chemical dumping (Brio Superfund Site) until stopped by the EPA for protection of the environment.
The soil was collected near a duck pond, at 1900 on 1/28/2021. The soil sample was wet, with corn kernel visible from the duck feed.
The soil sample was collected near the Brio Superfund industrial site that was located near San Jacinto College. This site was known for storing Petroleum and waste until EPA taken it down due to leakage of toxic waste. Contaminated soils were dug out and removed.
This sample was taken from a home garden on 1/13/20
The sample was collected from a drainage ditch off of West Airport in Fort Bend County. At the time of collection, there had been a short downpour, so the soil was quite moist and soggy.
The sample was collected, where plant growth was not much. There was some landscaping done on a non-regular basis which includes using pesticides. This place was also a place of interest as it is in very close proximity to chemical plants.
Sample of dirt collected near train tracks
The plot I selected dirt from was the area of dirt surrounding a residential house where pesticides have been used. The pesticide used was Home Defense Ortho brand.
16s rDNA:The sample was collected from a pond in Katy, Texas.
Sample collected off of a near-stationary stream that often collects itself with large quantities of water full of pesticide, when, applied by park monitors.
Sample was found outside a residence in a planter box in Cedar City UT. (37.657257, -113.073790)
Obtained near sewage drain by fishing spot.
The sample was collected near Memorial Park Conservancy. This place likely to have pesticide use or activity, because it is expected to discover organophosphate enzymes where pesticides are used, the collection of the sample was performed near an area where pesticides are ubiquitous. Following several inoculations, screening was carried out on the CMM plate to detect OP hydrolysis. The bacterial growth essentially indicated resistance to the OP compounds, whereas the “halo effect” was the evidence for OP hydrolysis. Moreover, CSM subcultures indicated a more intense color, as compared to the SSM subcultures. The findings of the Screening results indicated countless colonies with the “halo effect” on the CMM subculture. In summation, this experiment indicated a positive result, in that the collected soil possessed microorganisms that were able to express the organophosphorus hydrolase enzyme and organophosphate degradation.
The location I collected from was my backyard where my landlord regularly sprays insecticides (Ortho Home Defense)
The sample was collected in a wooded area where a small river was flowing through and it was a mile away from a farm. For inoculation results, the inoculation samples turned yellow in minimal media subcultures containining paraoxon (Px) which indicates production of P-nitrophenol due to OP hydrolysis. The color was brighter in CSM medium compared that in SSM medium which suggest that the bacteria prefer carbon as their food source. As for subcutlures containig methyl parathion (MP), they showed no colors after a series of inoculation. For screening result, the individual colonies and halos were visible on the CMM plate. In conclusion, the soil sample contained bacteria capable of expressing organophosphorus (OP) hydrolase and breaking down OP compound.
A sample of soil was taken from a home in Southern Utah that biyearly applies Ortho Home Defence Insect Killer. Of which has the active ingredients of Bifenthren and Zeta-Cypermethrin.

This was near the bayou of Macgregor Parkway, a park in Houston that sees a regular treatment of pesticides to fight of weeds and other unwanted organisms. Frequent flooding in the area also helps contribute to the variety of microorganisms that may be found.
Pesticide reported to have been used: Eight Insect Control (for Yard and Garden)
Active ingredient: Permethrin 2.50%
Site description: The site description is a home garden.
A pet-friendly apartment complex lawn. 2,4-D has been used for lawn maintenance.
Sample was taken near lake at Buffalo Run Park. Sample tested positive for OP hydrolysis for Px+CSM and Px+SSM.
Soil sample obtained upstream Mason Creek heading towards Buffalo Bayou assumed to have pesticide runoff from surrounding neighborhoods west of Houston. The soil was very damp and yellowish indicating excess iron.
Soil samples were taken from the lawn in front of the apartment.
The sample was collected 7-8 inches deep next to a bayou that usually get flooded during heavy rain.
My soil sample was isolated from a farm in Scottsville. Growth of soil bacteria was done for 2 weeks. Isolation of soil bacteria lasted for 5 weeks in CSM Mp, SSM Mp, CSM Px, and SSM Px. The liquid cultures were then plated on Mp and Px plates to grow single colonies. The single colonies were then picked with a toothpick and inoculated onto an Mp or Px plate. The isolated bacteria were then picked with a toothpick and mixed with 100 microliter of water. The mixture was then heated at 95 degrees C for 6 minutes before it was sent off for sequencing. The sequences were given back to me and input into BLAST to find the genus and species of bacteria that were isolated.
MR#1:
Bacteria: Enterobacter hormaechei
MR#2:
Bacteria: Enterobacter cloacae or Klebsiella pneumoniae
MR#3:
Bacteria: Raoultella planticola
This bacteria was formerly part of the Klebsiella genus. It is also used in bioremediation of cadmium from exposed soils. The bacteria is often found in soil and was attempted to be bioengineered and used in farm soil to destroy crop residues and produce ethanol.
MR#4:
Bacteria: Rosenbergiella nectarea
This bacteria was isolated from the flower nectar of almonds and grapefruit, then sequenced.

Soil Sample was collected from cotton field on Benton Rd in Richmond, Texas
<p>A soil sample collected from a grass farm in Crosby Texas.</p>
<p>The soil sample presented OP degradation</p>
<p>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.</p>
<p>CSM with Paraoxion was yellow in color, had some growth when plated on CSM agar, tested positive</p>
<p>Sample taken from rural area in South Houston on FM 2234. Exhibited a positive reaction with Px + SSM. Showed evidence of OP hydrolysis.</p>
<p>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.</p>
<p>An 12 inches hole was dig and soil was obtain. The soil sample was first inoculated in an enriched media and incubate at 37 degree Celsius. The soil containing media was then pipettes in minimal medical containing paraoxon and methyl parathion. Again was incubate for 7 day at 37 degree Celsius. This process was repeated until week 5. Then plated onto minimal agar with pesticide to observe for OP hydrolysis.</p>

<p>Coordinates: (29.647715, -95.716027).</p>
<p>The soil sample was collected at approximately 9AM on January 27th. The soil an its surrounding environment were wet when the sample was being collected. The collection site was at near the intersection between US-59 and US-59 BUS at Hungerford. There was no plants being grown on the collection site, however, there was some signs of plow and pipelines nearby the field. The sample was collected at approximately 8 inches depth of digging from the surface. This sample was collected for the testing of bacteria's pesticide degradation ability. </p>
<p>This location was chosen based on the fact that it was a farmland and active farming is done here in this 288 acre plot land. The location is openland across all the sides. The sample was collected from Houston outskirts, precisely from Richmond. The land soil was moist and had a dark texture. It almost looked as if new fresh batch of cultivation was seen. The location had just one Harlem road connecting it to the city. It was mostly quiet with few to none population around. The closest residential place from the location is 8 miles.There was no water body seen around. To get the sample I went inside the farmland towards the center and dug a hole. I took a scoop of soil sample. The soil sample was dark texture with very few fine particles, thick in context, had a distinct pungent smell to it. </p>

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.
Tolerant of Paraoxon but not able to degrade it, and intolerable of methyl parathion. A gross colony count of around 615.
The sample was collected after a rainy day from in front of a sewer grate. The sample was consistency similar to clay and was somewhat wet at the time of collection.

<p>This sample was collected near a ditch with visible runoff from two nearby businesses: a concrete pipe company and a landscaping firm. The site was chosen based on its vicinity to two EPA Superfund sites. Within about 100 yards of the sample collection site, there was a children's playground and a middle school. I found the site by following an industrial truck carrying some sort of fluid. I watched that truck and two others like it back up to a manmade body water and dump their contents into the pool. My assumption was that this was normal behavior for the business and because of recent rains, the pool often overflowed into the area that I collected from. </p>
<p>The sample was collected at a creek side. The soil is moist, light brown in color, and clay-like texture. The creek shown sign of marine life. </p>

<p>200 microliter inoculation of week 3's sample into fresh LB media. Samples have been shaken or one week in shaker machine (shook for four weeks total). SSM(MP) and CSM(MP) are clear, SSM(Px) is now clear after being slightly yellow, and CSM(Px) is slightly yellow.</p>
<p>Sample was obtained near the San Jacinto River, below US 59 North towards Cleveland.</p>
<p>was wet, clumped, and muddy.</p>
<p>Peach Orchard</p>
<p>Local plant nursery where Neem oil, Sulfur and Pyrethrin have been used recently.</p>
<p>Commercial Alfalfa Field in which Chlorpyrifos, Lambda-Cy, and Hexazinone was used in the 2019 growing season.</p>
<p>The site was the backyard of a home in a residential area. The area has multiple fruit trees. The owner had listed Roundup as a pesticide being used, but neither she nor myself were aware that that was an herbicide not a pesticide. The home was recently bought by the owner and could have had other pesticides used in the past, such as atrazine. </p>
<p>This sample was collected on the shoreline of a peninsula sticking into Crystal Bay that is directly adjacent to the oil refineries and industrial corridor of Houston. The location is a park with a large playground site, and while I was collecting, I noticed several people out fishing in the water. I chose this site because it was suggested by the lab instructor and there were previous soil samples collected here with positive results. I took the sample from an area close to the water where the soil was relatively soft from recent rains. </p>

<p>Shelby Bannerts Soil Sample - I collected this soil sample on a ranch thats has farming activity occurring frequently. In the surrounding area was livestock and a creek bin. The ground was pretty damp when the sample was collected. </p>
<p>Soil sample from a home garden in Star, ID. Pesticides that have been used are multiple glyphosate-based pesticides.</p>
<p>Southdown Park - I chose this area because it is an area that pesticides are heavily used and is regularly serviced. The site was damp at the time of collection because of the rains the weekend prior. The site is at the edge of the park before a ditch and the northbound feter road off of Hwy 288.</p>
