Microbial communities associated with anaerobic benzene degradation in a petroleum-contaminated aquifer.
Microbial community composition associated with benzene oxidation under in situ Fe(III)-reducing conditions in a petroleum-contaminated aquifer located in Bemidji, Minn., was investigated. Community structure associated with benzene degradation was compared to sediment communities that did not anaerobically oxidize benzene which were obtained from two adjacent Fe(III)-reducing sites and from me...
متن کاملComplete mineralization of benzene by aquifer microorganisms under strictly anaerobic conditions.
Benzene was mineralized to CO2 by aquifer-derived microorganisms under strictly anaerobic conditions. The degradation occurred in microcosms containing gasoline-contaminated subsurface sediment from Seal Beach, California, and anaerobic, sulfide-reduced defined mineral medium supplemented with 20 mM sulfate. Benzene, at initial concentrations ranging from 40 to 200 microM, was depleted in all m...
متن کاملAnaerobic benzene degradation by bacteria
Benzene is a widespread and toxic contaminant. The fate of benzene in contaminated aquifers seems to be primarily controlled by the abundance of oxygen: benzene is aerobically degraded at high rates by ubiquitous microorganisms, and the oxygen-dependent pathways for its breakdown were elucidated more than 50 years ago. In contrast, benzene was thought to be persistent under anoxic conditions un...
متن کاملImmunization Coverage in Selected Communities in the Niger Delta, Nigeria
Background: The Expanded Program on Immunization was launched in Nigeria in 1980 but the target for immunization coverage has been elusive. As part of its social responsibilities the Shell Petroleum Development Company (SPDC) supported immunization activities in the Niger Delta region of the country. In this study a cross sectional study was carried out to estimate the coverage of BCG, OPV, DPT...
متن کاملBiodegradation of Benzene under Anaerobic Condition using Enriched Microbial Culture
Benzene is a highly toxic organic contaminant having carcinogenic potential and a serious ground water contaminant. Refinery industry is a major source of benzene contamination in the environment. The present paper focuses on biodegradation of benzene under anaerobic condition by using enriched microbial consortium. Enriched bacterial isolates, identified by 16S rRNA sequencing technique were t...
