Abstract Several studies suggest that petroleum biodegradation can be achieved by either aerobic or anaerobic microorganisms, depending on oxygen input other electron acceptors and appropriate nutrients. Evidence from in vitro experiments with samples of formation water oils Pampo Field indicate is more likely to a joint achievement both bacterial consortium, refining our previous observations degradation. The consortium depleted, decreasing order, hydrocarbons > hopanes steranes...
Abstract High latitudes are experiencing intense ecosystem changes with climate warming. The underlying methane (CH 4 ) cycling dynamics remain unresolved, despite its crucial climatic feedback. Atmospheric CH emissions heterogeneous, resulting from local geochemical drivers, global factors, and microbial production/consumption balance. Holistic studies mandatory to capture complexity. Here, we report a large set of integrated biogeochemical data 387 samples, using concerted sampling...
Introduction: Living materials (biohybrids, textile-microbial hybrids, hybrid living materials) have gained much attention in recent years with enormous potential for applications biomedical science, the built environment, construction and architecture, drug delivery as environmental biosensors. contain matrices which incorporate microorganisms or biomolecules bioactive components. A cross-disciplinary approach, operating at intersection of creative practice scientific research, incorporated...
Biodegradation may result in physicochemical changes crude oil and natural gas properties, being responsible for the decrease of saturated hydrocarbons yielding heavy with low economic value.Studies on diversity microbial catabolic genes reservoirs are scarce could help to predict potential a petroleum sample be biodegraded.The aim this study was evaluate involved hydrocarbon degradation Brazilian samples (biodegraded non-biodegraded) through construction analysis gene libraries (alkane...
Unraveling the microbial diversity and its complexity in petroleum reservoir environments has been a challenge throughout years. Despite techniques developed order to improve methodologies involving DNA extraction from crude oil, enrichments using different culture conditions can be applied as way increase recovery of with low cellular density for further microbiological analyses. This work aimed at evaluation matrices (arenite, shale polyurethane foam) support materials growth biofilm...
Abstract Methane‐cycling is becoming more important in high‐latitude ecosystems as global warming makes permafrost organic carbon increasingly available. We explored 387 samples from three high‐latitudes regions (Siberia, Alaska and Patagonia) focusing on mineral/organic soils (wetlands, peatlands, forest), lake/pond sediment water. Physicochemical, climatic geographic variables were integrated with 16S rDNA amplicon sequences to determine the structure of overall microbial communities...
Bacillus pumilus strain CCMA-560 was isolated from an oil-contaminated mangrove swamp and shown to produce biosurfactants. The appears be capable of degrading some plant cell wall-related compounds, including hemicelluose pectin. Genes for biopolymer export polysaccharide intercellular adhesin synthesis were also annotated.
Gordonia amicalis strain CCMA-559 was isolated from an oil-contaminated mangrove swamp and shown to produce biosurfactants. This is a strict aerobe that readily degrades array of carbon sources, including N-acetylglucosamine, cellobiose, Tween 80, 4-hydroxybenzoic acid, and, like other G. strains, likely desulfurizes dibenzothiophene.
Microbial degradation of petroleum is a worldwide issue, which causes physico-chemical changes in its compounds, diminishing commercial value. Biosurfactants are chemically diverse molecules that can be produced by several microorganisms and enable microbial access to hydrocarbons. In order investigate both activities, function-driven screening assays for biosurfactant production hydrocarbon biodegradation were carried out from metagenomic fosmid library. It was constructed the total DNA...
