Petroleum Oil

Petroleum products are used for energy production and an essential part of our day-to-day lives especially in vehicles, ships, and industries. Accidental leakages occur easily and wastage petroleum is also discarded in the environment without any further processing causing environmental pollution. Diesel contributea big part topetroleum pollution. The current study was aimed to identify diesel degrading bacteria and determine some conditions to evaluate their best degradation capability. We identified Aeromonas spp., Bacillus spp., and Enterobacter spp. from diesel contaminated soil and found that Aeromonas spp. and Bacillus spp. grow best with 10% to 15% diesel whereas Enterobacter spp. can grow quite well with 20% diesel concentration at a higher temperature (40oC) than the previous two bacteria. Aeromonas spp. worked well at low pH (pH 4 to pH 6) whereas Bacillus spp. and Enterobacter spp. worked best at higher pH (pH 10).

Degrading Bacteria

DDT is one of the most persistent pesticides among all the different types of organo-chlorine pesticides used. Among all the degradation methods, bacterial degradation of DDT is most effective. The present study was conducted to isolate different bacteria present in waste samples which have the ability to degrade DDT present in the soil in the minimum possible period of time and to observe the effect of different physical and chemical properties of the soil samples. Many pesticide degrading bacteria were isolated and identified through cultural, biochemical tests and further identified by 16S RNA sequencing method. The most potent strain DDT 1 growth in mineral salt medium supplemented with DDT as the only source of carbon (5-100 PPM) and was monitored at an optical density of 600 nm. The growth parameters at different physio-chemical conditions were further optimized. The result showed that Enterobacter cloacae had maximum growth in 15 days. FTIR analysis of the residual DDT after 15 days incubation showed that Enterobacter cloacae was able to degrade pesticide into its further metabolites of DDD, DDE, DDNU and other components can be used for biodegradation of DDT present in contaminated soil and water ecosystems.

Abstract As a step toward bioaugmentation of coking wastewater treatment 45 bacteria strains were isolated from the activated sludge of a coking wastewater treatment plant (WWTP). Three strains identified as Bacillus cereus, Pseudomonas synxantha, and Pseudomonas pseudoaligenes exhibited high dehydrogenase activity which indicates a strong ability to degrade organic matter. Subsequently all three strains showed high naphthalene degradation abilities. Naphthalene is a refractory compound often found in coking wastewater. For B. cereus and P. synxantha the maximum naphthalene removal rates were 60.4% and 79.8%, respectively, at an initial naphthalene concentration of 80 mg/L, temperature of 30 °C, pH of 7, a bacteria concentration of 15% (V/V), and shaking speed of 160 r/min. For P. pseudoaligenes, the maximum naphthalene removal rate was 77.4% under similar conditions but at 35 °C.
