“…Those isolates responded differently to the same 2,2-DCP concentration. Each species may differ in the regulation of substrate uptake and tolerance mechanism to toxic compounds (Ghoreishi et al, 2017). Nevertheless, both strains have a considerable ability to utilize 2,2-DCP at high concentration.…”

Aims: The use of herbicide effectively controls weeds in agricultural practice. However, its release to the surrounding surface water bodies may lead to environmental issues. The aim of this study was to isolate the bacteria that were able to remove 2,2-dichloropropionic acid (2,2-DCP) from a paddy field located in Malang. Methodology and results: The 2,2-DCP degrading bacteria were isolated and their ability to grow on higher 2,2-DCP concentrations (50 and 80 mM) was tested. Bacterial degradation of 2,2-DCP was examined through measurement of released chloride ions. The potential isolates were identified according to their 16S rDNA sequences. Two potential isolates, BB9.2 and BC14.3 were observed for their growth on 20, 50, and 80 mM 2,2-DCP. Isolate BC14.3 had the shortest cell doubling time of approximately 4.1 h with 100% 2,2-DCP (20 mM) utilization, whereas BB9.2 was only able to degrade 80% of 2,2-DCP at the same concentration. The 16S rDNA gene sequences suggested that BB9.2 and BC14.3 belong to Acinetobacter calcoaceticus and Pseudomonas plecoglossicida, respectively. Conclusion, significance and impact of study: Bacterial strains with 2,2-DCP degrading potentials were successfully isolated from long-term exposed agricultural soil. They demonstrated notable utilization of the organic halide. This is the first time that strains of A. calcoaceticus and P. plecoglossicida were reported to utilize 2,2-DCP.

“…The tolerance to high concentration of 2,2-DCP may be related to frequent exposure of the organic halide on the sampling location. Bacterial species survived in a polluted soil would lead to a more efficient pollutant biodegrader (Ghoreishi et al, 2017).…”

Petroleum crude oil is transported on a global scale through marine vessels and barges by the sea route. Oil spills into the marine environment are known to cause long term effects on the health of marine life and human beings in addition to harming the eco-system. In this study, petroleum refinery effluent samples were collected and analyzed for their physico-chemical properties. Thirty two bacterial strains were isolated by direct isolation and post enrichment in crude oil. Among these, fourteen isolates could utilize petroleum hydrocarbons as sole carbon source on Bushnell Hass Agar plates supplemented with crude oil within 2 days. Out of these fourteen strains, four could decolorize 2,6-dichlorophenol indophenol within 36 h completely. They were identified as Bacillus cereus WD22, Pseudomonas aeruginosa WD23 and WDE11 (2 strains) and Acinetobacter baumannii OCB1 by 16sRNA sequencing. All four strains could tolerate salinity up to 4.0%w/v. The reduction in total petroleum hydrocarbons in sea water spiked with crude oil (1.0%v/v) supplemented with trace amounts of glucose and yeast extract was studied by gravimetric analysis. P. aeruginosa WD23 degraded 27.25% of supplied petroleum crude oil under limited nutrient conditions in seawater in 15 days.

“…Petroleum hydrocarbon contaminated soils accumulate in the environment due to leaks from storage tanks, aged pipelines, and waste disposal sites (Liu et al, 2011;Ghoreishi et al, 2017); during the exploration, extraction, transportation, and storage of crude and its various derivatives. Environmental damage also arises due to the intentional discharge of oil and oily wastes into the environment (Lai et al, 2009).…”

“…Biological approaches, on the other hand, provide more interesting techniques of treating petroleum contamination in comparison with chemical and physical methods (Ghoreishi et al, 2017;Lors et al, 2012). Bioremediation is a biological treatment approach that has been recognized as an efficient, versatile, and environmentally friendly solution when compared to the variety of remediation methods available.…”

Innovative technologies to combat environmental pollution are a significant part of sustainability research due to their increasing economic and environmental impact. The present biological process-based research study described herein was conducted in three phases. It investigated the effects of rhamnolipid-enhanced soil washing (phase 1), bioremediation treatment using indigenous microorganisms (phase 2), and the effect of four specific environmental and nutritional conditions (phase 3) on the biodegradation of petroleum hydrocarbons (PHC) in drill cuttings and petroleum-contaminated soil obtained from sites in northeastern British Columbia. For phase 1, maximum PHC reduction recorded for total petroleum hydrocarbon (TPH) and the petroleum hydrocarbon fractions-F2, F3 and F4 fractions was 58.5%, 48.4%, 63.5% and 59.8% respectively for petroleum-contaminated soil, and 76.8%, 85.4%, 71.3% and 76.9% respectively for drill cuttings. In phase 2, maximum PHC reduction of TPH, F2 and F3 fractions was 94.9%, 98.8% and 94.0% respectively for petroleum-contaminated soil and 82.6%, 94.9% and 59.5% respectively for drill cuttings following 50 days of rhamnolipid-mediated biodegradation treatment. Results from experiments conducted in phase 3 confirmed the importance of oxygen availability in biodegradation and indicated the inhibitory effects of excessive addition of biosurfactants and nutrients to hydrocarbon biodegradation treatments. Promising TPH degradation results were observed in conditions that normally slow down biodegradation. TPH degradation of 59.0%, 59.8% and 56.7% were observed in experiments conducted at an average temperature of-7.46 °C, and in waterlogged and airtight conditions respectively. These results provide important insight on rhamnolipid-mediated biodegradation and indicate the high potential of rhamnolipid iii washing and bioremediation treatments as a combined approach to reduce PHC to levels within regulatory standards. iv
