“…B-7 was the only one that degraded all fractions, even asphalts (40.6%), which are elusive to degradation by other treatments. The concentration of contaminants for the abiotic control by the end of the assessment showed no significant differences with the initial concentrations (in average 4.2E+04 mg kg −1 versus 3.9E+04 mg kg −1 ; standard error ~ 0.06%), suggesting that abiotic mechanisms like volatilization or dilution may not significantly contribute to degradation in these assays [31]. These observations indicated that fungal treatment improved the biodegradation of recalcitrant fractions like aromatics, resins and asphaltenes compared to natural attenuation in the polluted soil.…”

“…The temperature was maintained at 27°C as in the marine environment as the average temperature of Indian seawater is observed to be between 25-28°C 5 . Spillage of oil into marine and fresh water environment causes an increase in carbon content and a drastic decrease in nitrogen content 23 . It has been reported that the addition of a simple carbon source such as glucose increased the biodegradation rate of total petroleum hydrocarbons (TPH) in contaminated samples 24 .…”

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.

“…Biomass production remained stable, after which the culture reached the stationary phase. This forces microbes to produce enzymes to degrade crude oil to utilize it as a source of energy and these enzymes which were capable of producing certain secondary metabolites (Guru et al, 2013, Adnan et al, 2018 P. gessardi was a novel lipase degrading bacteria from the oil spilled soil which can be useful for the remediation of oil contaminated soil. (Veerabagu et al, 2014), Pseudomonas synxantha PS1 a lipase producing strain from oil well produced water having strong biodegradabitility of waste grease (Cai et al, 2016) as well as fungi aspergillus nigar able to degrade petroleum hydrocarbon (Mauti et al, 2016) It can be concluded that from the results of the present study that Bacillus pumilus could be used as new potent microbial source of lipase.…”

Soapstocks is a value-added by-product separated from vegetable oil refi ning operations. Bacillus sp. is a good enzyme producer. The present research paper focused at isolation, screening and identifi cation of Bacillus sp. from soapstock samples. Cotton seed soapstock samples used in the study were 7% oil rich gelatinous dark brown chemical compound, which were enriched, serially diluted and spread on tributyrin agar plates, to isolate lipase positive cultures. Qualitative analysis of lipase producing microorganisms was done by plate assay on tributyrin agar plate and zone of hydrolysis measured. Bacillus sp. were further screened for cellulase and protease production by plate assay. Two cultures were identifi ed on the basis of molecular and biochemical characteristics as Bacillus licheniformis (3B) and Bacillus pumilus (18B). Among selected Bacillus cultures Bacillus licheniformis and Bacillus pumilus gavegood zone of lipase and cellulasehydrolysis. Bacillus pumilus was highly protease producing organism. Quantitative analysis of Lipase production activity measured spectrophotometrically using p-nitrophenyl palmitate (p-NPP) as substrate. Bacillus licheniformis showed 1.72 U/ml lipase productions whereas Bacillus pumilus (18B) has 2.59 U/ml. Phylogenetic trees showed similarity with other highly similar species.
