Background

Petrochemical industry is one of the fastest growing industries. This industry has immense importance in the growth of economy and manufacture of large varieties of chemicals. The petrochemical industry is a hazardous group of industry generating hazardous waste containing organic and inorganic compounds. In spite of the present treatment process, the hazardous waste compounds are found untreated to the acceptable level and found discharged at soil–water environment resulting into the persistent organic–inorganic pollutant into the environment. The bioremediation will be the innovative techniques to remove the persistent pollutants in the environment.

Result

Petrochemical contaminated site was found to be a rich source of microbial consortium degrading polycyclic aromatic hydrocarbons. Indigenous microbial consortiums were identified and used for bioremediation of polycyclic aromatic hydrocarbons (naphthalene and anthracene) at the concentrations of 250, 500, and 750 ppm. The potential microorganism was also identified for naphthalene and anthracene, and their bioremediation was studied at varying concentrations. The bioremediation with consortium was found to be comparatively more effective than the potential microorganism used for bioremediation of each compound. Pseudomonas aeruginosa a potential organism was identified by 16S rRNA and further studied for the gene responsible for the PAH compounds.

Conclusion

Indigenous microorganism as a consortium has been found effective and efficient source for remediation of organic compound—Polycyclic aromatic hydrocarbon and this will also be applicable to remediate the toxic compounds to clean up the environment.

石化废料多环芳烃的微生物降解。

背景

石化行业是发展最快的行业之一。该行业对经济增长和多种化学品的制造具有极其重要的意义。石化工业是危险的行业，会产生包含有机和无机化合物的有害废物。尽管采用了目前的处理方法，但仍未将有害废料化合物处理到可接受的水平，并发现它们在土壤-水环境中排放，导致持久的有机-无机污染物进入环境。生物修复将是去除环境中持久性污染物的创新技术。

结果

发现石油化学污染场所是微生物聚生体降解多环芳烃的丰富来源。确定了土著微生物联盟，并将其用于浓度为250、500和750 ppm的多环芳烃（萘和蒽）的生物修复。还确定了潜在的微生物萘和蒽，并研究了其在不同浓度下的生物修复作用。发现用财团进行的生物修复比用于每种化合物的生物修复的潜在微生物相对更有效。铜绿假单胞菌通过16S rRNA鉴定出潜在的生物，并进一步研究了负责PAH化合物的基因。

结论

已发现土著微生物作为一个财团可以有效地补救有机化合物多环芳烃，这也将用于补救有毒化合物以净化环境。
