Abstract

The eleven combinations of four isolates, S. maltophilia, P. hibiscicola, P. aeruginosa, and P. monteilii, were prepared and screened for chlorpyrifos (CP) degradation. Among these combinations, four highly CP degrading consortia were identified: D: S. maltophilia, P. hibiscicola, P. monteilii, E: P. hibiscicola, P. aeruginosa, P. monteilii, F: S. maltophilia, P. hibiscicola, and G: S. maltophilia, P. aeruginosa. These combinations were found to be mutually compatible, exhibiting no lysis or inhibition zones. Their application significantly decreased in CP content from 37.6 to 68.6% as compared to control. Consortia-treated soil also displayed reduced bio-concentration factor and translocation of CP in W. somnifera. A significant increase in biomass (40–71.2%), protein content (38–66.6%), chlorophyll (24.7–52.3%), and secondary metabolite of W. somnifera was observed after the application of consortia. The activities of soil enzymes (alkaline phosphatase, dehydrogenase, and N-acetyl glucosaminidase), availability of nutrients, and soil microbial biomass carbon were also enhanced by the inoculation of consortia in soil. Overall, the results indicated that the consortium of S. maltophilia and P. aeruginosa exhibited the highest potential for CP degradation and plant growth promotion compared to the others. This consortium could be effectively utilized for the rapid degradation of CP in agricultural soil vis-a-vis improvement in the productivity of the plants.

毒死蜱降解、土壤修复和促进植物生长的细菌群落探索

制备了嗜麦芽葡萄球菌（S. maltopophilia）、木苁莉娅葡萄球菌（P. hibiscicola）、铜绿葡萄球菌（P. aeruginosa）和蒙泰利葡萄球菌（P. monteilii） 4个菌株的11个组合，并对其进行了降解毒死蜱（CP）的筛选。在这些组合中，鉴定出4个高CP降解菌群：D: S.嗜麦芽菌，P. hibiscicola， P. monteilii, E: P. hibiscicola， P. aeruginosa， P. monteilii, F: S.嗜麦芽菌，P. hibiscicola和G: S.嗜麦芽菌，P.铜绿菌。这些组合被发现是相互兼容的，没有裂解或抑制区。与对照相比，它们显著降低了CP含量，从37.6%降至68.6%。菌落处理土壤中CP的生物富集因子和转运也明显降低。结果表明，施用黄芪可显著提高柠条生物量（40-71.2%）、蛋白质含量（38-66.6%）、叶绿素含量（24.7-52.3%）和次生代谢产物。接种菌落可提高土壤酶（碱性磷酸酶、脱氢酶和n -乙酰氨基葡萄糖酶）活性、养分有效性和土壤微生物生物量碳。结果表明，嗜麦芽假单胞菌和铜绿假单胞菌组合对CP的降解和促进植物生长的潜力最大。该联合体可以有效地用于农业土壤中CP的快速降解，从而提高植物的生产力。

期刊介绍： Biodegradation publishes papers, reviews and mini-reviews on the biotransformation, mineralization, detoxification, recycling, amelioration or treatment of chemicals or waste materials by naturally-occurring microbial strains, microbial associations, or recombinant organisms. Coverage spans a range of topics, including Biochemistry of biodegradative pathways; Genetics of biodegradative organisms and development of recombinant biodegrading organisms; Molecular biology-based studies of biodegradative microbial communities; Enhancement of naturally-occurring biodegradative properties and activities. Also featured are novel applications of biodegradation and biotransformation technology, to soil, water, sewage, heavy metals and radionuclides, organohalogens, high-COD wastes, straight-, branched-chain and aromatic hydrocarbons; Coverage extends to design and scale-up of laboratory processes and bioreactor systems. Also offered are papers on economic and legal aspects of biological treatment of waste.
