“…Biodegradation of hydrocarboncontaminated soils which use the ability of microorganisms to degrade and/or detoxify organic contamination, has been considered as an efficient, economic, versatile and environmentally sound treatment for kerosene contaminated soils [9][10][11] . There was no microorganism located to fully degrade petroleum hydrocarbon molecule.…”

Isolated Bacteria from the roots of barley were studied; two stages of processes Isolated and screening were applied in order to find the best bacteria to remove kerosene from soil. The active bacteria are isolated for kerosene degradation process. It has been found that Klebsiella pneumoniae sp. have the highest kerosene degradation which is 88.5%. The optimum conditions of kerosene degradation by Klebsiella pneumonia sp. are pH5, 48hr incubation period, 35°C temperature and 10000ppm the best kerosene concentration. The results 10000ppm showed that the maximum kerosene degradation can reach 99.58% after 48 h of incubation. Higher Kerosene degradation which was 99.83% was obtained at pH5. Kerosene degradation was found to be maximum at 35°C with 98.63%, where 10000ppm kerosene showed the highest degradation at 99.527%. The results indicate that the isolated Klebsiella pneumonia sp. is extremely efficient in degrading kerosene hydrocarbons.

“…In addition, bioremediation technology is believed to be noninvasive and relatively cost-effective [21]. Biodegradation by natural populations of microorganisms represents one of the primary mechanisms by which petroleum and other hydrocarbon pollutants can be removed from the environment [22] and is cheaper than other remediation technologies and the most efficient for environment safe depollution [23].…”

Lubricants are very often found in nature under waste-oil forms and represent for the environment a real danger of pollution due to the difficulty of their biodegradation. The situation is especially worrying in most developing countries in particular those of Sub-Saharan Africa due to the absence of regulation or control. The present work aims to isolate bacterial strains able to degrade hydrocarbons which can later be used in biotechnology for environments depollution. Oil-contaminated wastewater samples were collected in Ouagadougou city (Burkina Faso) and then used as source of bacterial isolation. Appropriate amounts of samples were inoculated to a mineral salt medium (MS) with Total Quartz 9000 oil as sole carbon and energy source and then incubated for enrichment, prior to microbe isolation. Two bacterial strains namely S2 and S 7 were isolated from the enrichment cultures. The strains were tested for their ability to degrade other hydrocarbons (i.e. gasoline, diesel oil, brake oil) and for temperature, pH and salt concentration ranges for growth before their biochemical characteristics were defined. Based on their morphological, physiological and biochemical traits, strains S 2 and S 7 belong to Acinetobacter and Pseudomonas genera, respectively.

“…Bioremediation (the use of naturally occurring or deliberately introduced microorganisms to breakdown, neutralize or remove environmental pollutants, in order to clean a polluted site) is the promising environmental-friendly and relatively cost-effective technology for the treatment of contaminated sites [7]. One of the primary mechanisms by which petroleum and other hydrocarbon pollutants can be removed from the environment is through biodegradation, a process carried out by natural populations of microorganisms [8]; it appears to be more cost-effective than other remediation technologies [8]. Even though hydrocarbon degrading microorganisms are widely distributed in nature, it may be difficult to obtain isolates that possess degradative abilities for all components of petroleum.…”

There is a continuous search for environmental-friendly methods to address oilpolluted environments, hence this study aimed to establish the potential of using tropical estuarine bacterial strains for degradation of crude oil in polluted environment. Microbial degradation of hydrocarbons has been considered a promising, natural, less toxic and cost-effective technology. Lignocellulose-utilizing bacterial strains (Bacillus megaterium strain NOB, Streptomyces pseudogriseolus strain EOB and Paenibacillus sp. strains ROB) were isolated from decomposing wood residues in a tropical lagoon. They were identified on the basis of morphological and biochemical characteristics, observation under scanning electron microscope and 16S rRNA gene sequencing. Microbial growth assessment coupled with biosurfactant production were performed in triplicates under aerobic batch conditions in Erlenmeyer flasks containing mineral salts medium fortified with trace elements and crude oil as the sole carbon source. The generation times of strains NOB, EOB and ROB were 28.3, 44.9 and 46.8 h respectively; with specific growth rates of 14.2, 8.9 and 8.6 h-1, respectively on crude oil. Gas chromatographic analysis of residual hydrocarbons from the growth cultures of isolates revealed that the three strains had degraded the oil by 89.34, 86.33 and 79.37%, respectively at the end of 21 days. The cell hydrophobicity of the bacterial strains also reached 83.6, 79.4 and 69.4%, respectively. The results from this study suggest that wood-digesting bacterial strains from a tropical lagoon possess hydrocarbon utilization capabilities. They could therefore have potentials for deployment in the bioremediation of petrochemical spills in polluted environments.
