Abstract

Nineteen hydrocarbon degrading microorganisms were isolated from Ten hydrocarbon contaminated sites and were identified on the basis of morphological, biochemical and molecular characteristics as Acenetobacter junii, pantoea dispersa, Bacillus spizizenii, and Pseudomonas aeruginosa. The study illumined high density of bacteria acclimatized for biodegradation of hydrocarbon in soil. The isolates were examined for other hydrocarbon degradation in media supplemented with Diesel, Benzene, Petrol and Cyclohexane at three different concentrations viz 5%, 10% and 15% incubated for 3 different time intervals 5, 10 and 15 days. The results indicated that all the isolates possessed potential to degrade the wide variety of hydrocarbons. The most efficient among them was Acenetobacter junii which degraded all tested hydrocarbon showing maximum growth at 5% concentration and 10 days incubation. It could be concluded that native flora of hydrocarbon contaminated site adapt to the environmental condition and could be implicated to remove hydrocarbons.

从污染土壤中分离的四种本地菌株对碳氢化合物的生物降解效率

从10个烃类污染地点分离到19种烃类降解微生物，根据形态、生化和分子特征鉴定为朱尼乳酸菌、分散泛菌、棘芽孢杆菌和铜绿假单胞菌。该研究揭示了土壤中高密度细菌对烃类生物降解的适应性。在柴油、苯、汽油和环己烷浓度分别为5%、10%和15%的培养基中培养5天、10天和15天，检测菌株对其他碳氢化合物的降解能力。结果表明，所有分离物都具有降解多种烃类的潜力。其中，朱尼乳酸菌的降解效率最高，在5%的浓度和10 d的培养条件下，其生长速度最快。由此可见，烃类污染场地的原生植物群适应了环境条件，可能参与了烃类的脱除。

期刊介绍： International Journal of Management Science and Engineering Management (IJMSEM) is a peer-reviewed quarterly journal that provides an international forum for researchers and practitioners of management science and engineering management. The journal focuses on identifying problems in the field, and using innovative management theories and new management methods to provide solutions. IJMSEM is committed to providing a platform for researchers and practitioners of management science and engineering management to share experiences and communicate ideas. Articles published in IJMSEM contain fresh information and approaches. They provide key information that will contribute to new scientific inquiries and improve competency, efficiency, and productivity in the field. IJMSEM focuses on the following: 1. identifying Management Science problems in engineering; 2. using management theory and methods to solve above problems innovatively and effectively; 3. developing new management theory and method to the newly emerged management issues in engineering; IJMSEM prefers papers with practical background, clear problem description, understandable physical and mathematical model, physical model with practical significance and theoretical framework, operable algorithm and successful practical applications. IJMSEM also takes into account management papers of original contributions in one or several aspects of these elements.
