Sulfate-reducing bacteria (SRB) have been studied extensively in the petroleum industry due to their role corrosion, but very little is known about sulfur-oxidizing (SOB), which drive oxidization of sulfur-compounds produced by activity SRB reservoirs. Here, we surveyed community structure, diversity and abundance SOB simultaneously based on 16S rRNA, dsrB soxB gene sequencing, quantitative PCR analyses, respectively reservoirs with different physicochemical properties. Similar SRB, were...
Microbial populations associated with microbial enhanced oil recovery (MEOR) and their abundance in the Xinjiang Luliang water-flooding petroleum reservoir were investigated using 16S rRNA, nitrate reductases, dissimilatory sulfate reductase, methyl coenzyme-M reductase-encoded genes to provide ecological information for potential application of MEOR. rRNA gene miseq sequencing revealed that this harbored large amounts taxa, including 155 bacterial 7 archeal genera. Among them, Arcobacter,...
Abstract To investigate the spatial distribution of microbial communities and their drivers in petroleum reservoir environments, we performed pyrosequencing partial 16S rRNA, derived from 20 geographically separated water-flooding reservoirs two that had not been flooded, China. The results indicated distinct underground inhabited different reservoirs. Compared with bacteria, archaeal alpha-diversity was strongly correlated environmental variables. variation bacterial community compositions...
Enhanced oil recovery using indigenous microorganisms has been successfully applied in the petroleum industry, but role of remains poorly understood. Here, we investigated relationship between microbial population dynamics and production performance during a water flooding process coupled with nutrient injection low-temperature reservoir. Samples were collected monthly over two-year period. The composition samples was determined 16S rRNA gene pyrosequencing real-time quantitative polymerase...
This study used an exogenous lipopeptide-producing Bacillus subtilis to strengthen the indigenous microbial enhanced oil recovery (IMEOR) process in a water-flooded reservoir laboratory. The processes and driving mechanisms were investigated terms of changes properties interplay between populations. is lipopeptide producer, with short growth cycle no oil-degrading ability. facilitates IMEOR through improving emulsification accelerating as carbon source. Microbial community studies using...
Abstract. Microbial communities in injected water are expected to have significant influence on those of reservoir strata long-term flooding petroleum reservoirs. To investigate the similarities and differences microbial strata, high-throughput sequencing partial 16S rRNA samples collected from wellhead downhole injection wells, production wells a homogeneous sandstone heterogeneous conglomerate were performed. The results indicate that small number populations shared between reservoir,...
It was found that Bacillus sp. Y1 could secrete alkaline pectinase with suitable enzyme system for powerful and fast degumming of ramie fiber. In this study, the medium components fermentation conditions were optimized by some statistical methods including mixture design, fractional factorial central composite design response surface methodology, single factor method enhancing production. The production culture shaken at 34°C 60 h in 50 mL containing 10.5% (w/v) carbon source (consisting...
