Petroleum contamination and bioaugmentation in bacterial rhizosphere communities from Avicennia schaueriana

Braz. j. microbiol; 49 (4), 2018
ABSTRACT Anthropogenic activity, such as accidental oil spills, are typical sources of urban mangrove pollution that may affect mangrove bacterial communities as well as their mobile genetic elements. To evaluate remediation strategies, we followed over the time the effects of a petroleum hydrocarbon deg...

Temporal assessment of microbial communities in soils of two contrasting mangroves

Braz. j. microbiol; 49 (1), 2018
ABSTRACT Variations in microbial communities promoted by alterations in environmental conditions are reflected in similarities/differences both at taxonomic and functional levels. Here we used a natural gradient within mangroves from seashore to upland, to contrast the natural variability in bacteria, cy...

Characterization of dioxygenases and biosurfactants produced by crude oil degrading soil bacteria

Braz. j. microbiol; 48 (4), 2017
ABSTRACT Role of microbes in bioremediation of oil spills has become inevitable owing to their eco friendly nature. This study focused on the isolation and characterization of bacterial strains with superior oil degrading potential from crude-oil contaminated soil. Three such bacterial strains were selec...

Uso de Leersia hexandra (Poaceae) en la fitorremediación de suelos contaminados con petróleo fresco e intemperizado

Rev. biol. trop; 65 (1), 2017
ResumenLa industria petrolera ha generado derrames crónicos de petróleo y su acumulación en Gleysoles en zonas anegadas en el estado de Tabasco, en el sureste de México. El anegamiento es un factor que limita el uso de tecnologías de remediación por el alto costo y los bajos niveles de degradación...

Sphingomonas from petroleum-contaminated soils in Shenfu, China and their PAHs degradation abilities

Braz. j. microbiol; 47 (2), 2016
Abstract Members of the Sphingomonas genus are often isolated from petroleum-contaminated soils due to their unique abilities to degrade polycyclic aromatic hydrocarbons (PAHs), which are important for in situ bioremediation. In this study, a combined phenotypic and genotypic approach using streptomycin-...
