“…Alcanivorax sp. is reported to produce a biosurfactant and biodegradation of n-alkylcycloalkanes and n-alkylbenzenes [23]. Remarkable number of Alcanivorax spp in surface and sediment samples and negligible oil contamination of lake encourage us to predict that there may be oil reservoirs in the vicinity of the lake.…”

Total seventy four bacteria were isolated from Lonar soda lake of Maharashtra state, India. Eleven isolates were identified using morphological, biochemical and molecular analysis. The bacteria isolated belonged to phylum firmicutes and proteobacteria. Majorities (eight) were firmicutes and three were proteobacteria. For the first time we are reporting Alcanivorax spp. which is a genus well known for its oil degradation capacity, indicate the probable existence of oil reservoir in vicinity of Lonar lake. In addition all the eleven bacteria are potential producers of industrially important enzymes, pigments, antibiotics as well.

“…The degradation rate of crude oil enhanced along with the increasing amount of wheat bran, when the amount of wheat bran was 25 of the soil volume, the degradation rate of oil arrived at 56. 8 after 90 days' bioremediation. This hydrocarbon-degrading strain will play an important role in bioremediation of crude oil pollution of environments, such as soil, water and oily sludge, etc.…”

“…In many situations, soil rehabilitation can be accomplished by bioremediation. Bioremediation, involving bioaugmentation and biostimulation, being an economical and eco-friendly approach, has emerged as the most advantageous soil and water clean-up technique for polluted sites containing heavy metals or organic pollutants [8][9][10][11] . Addition of pre-grown microbial cultures to enhance the degradation of unwanted compounds (bioaugmentation) and injection of nutrients and other supplementary components to the native microbial population to induce propagation at a hastened rate (biostimulation), are the most common approaches for in situ bioremediation of accidental spills and chronically polluted sites worldwide [12][13][14] .…”

A bacterial strain, named KL2-13 was isolated by means of enrichment culture from soil contaminated by heavy oil from Karamay of Xinjiang Oilfield. The strain KL2-13 was identified as Bacillus according to its morphological, physiological, biochemical, and 16S rDNA sequence characteristics. The biodegradation experiments were made to research whether the bacterial strain KL2-13 could accelerate the biodegradation progress. The influence of inoculum concentration, N, P sources and the amount of wheat bran on the degradation ability of the strain was investigated. The petroleum polluted soil collected from Karamay was treated by the strain KL2-13 for 90 days at the definite water content. The results showed that the petroleum hydrocarbon pollutants degraded faster. The bioremediation effect was best when the inoculum concentration of the strain KL2-13 was 10 . There was an optimum matching value between the growth of microbe and the amount of the nutrients added, the optimum content of N was 0.2 , and P 0.05 . The degradation rate of hydrocarbon pollutants enhanced along with the increasing amount of wheat bran, when the amount of wheat bran was 25 of the soil volume, the degradation rate of oil arrived at 56.8 after 90 days' bioremediation.

“…Therefore, biodegradation of oil must be completed by different type and function of microbes [2] . Most relevant researches used defined mixed culture composed of purified single oil-degrading bacterial strain as the research object [3][4][5] .…”

A thermophilic oil-degrading bacterial group, named KL6-3 was screened by means of enrichment culture from soil contaminated by heavy oil from Karamay of Xinjiang Oilfield. Its oil degradation rate was up to 48.6% at 45 and oil concentration of 10g·L -1 (data not reported). To evaluate biodegradation to petroleum polluted soil of the KL6-3, the soil samples collected from Karamay supplemented with the KL6-3 group were incubated for 90 days at 45. The physicochemical quality, microorganism quantity and hydrocarbon component of the oil polluted soil were studied. The results showed that the presence of KL6-3 group could enhance the degradation of crude oil. The petroleum hydrocarbon was mainly degraded by microorganism. The saturates and aromatics were easy to be degraded and the resin and asphaltene were hard to be degraded. The microorganism quantity was increased significantly with manual composting.
