A highly specific Serratia-infecting T7-like phage inhibits biofilm formation i...

Prokaryotic diversity in the rhizosphere of organic, intensive, and transitiona...

Despite a continuous rise in consumption of coffee over the past 60 years and recent studies showing positive benefits linked to human health, intensive coffee farming practices have been associated with environmental damage, risks to human health, and reductions in biodiversity. In contrast, organic farming has become an increasingly popular alternative, with both environmental and health benefits. This study ...

Screening and characterization of prophages in Desulfovibrio genomes

Bacteria of the genus Desulfovibrio belong to the group of Sulphate Reducing Bacteria (SRB). SRB generate significant liabilities in the petroleum industry, mainly due to their ability to microbiologically induce corrosion, biofilm formation and H2S production. Bacteriophages are an alternative control method for SRB, whose information for this group of bacteria however, is scarce. The present study developed a...

Desulfovibrio alaskensis prophages and their possible involvement in the horizo...

Desulfovibrio alaskensis is a Gram-negative bacterial species that belongs to the group of Sulphate Reducing Bacteria (SRB) and presents prophages in genomes, a common characteristic of the genus Desulfovibrio. Genetic material can be transported by outer membrane vesicles, however, no data regarding the production of these vesicles has been reported for D. alaskensis. To verify the expression of D. alaskensis ...

Effect of salinity in heterotrophic nitrification/aerobic denitrification perfo...

Mixed cultures salt acclimated showed high efficiency in heterotrophic nitrification/aerobic denitrification process in hypersaline conditions. They were able to remove 80% of ammonium in Heterotrophic Nitrification Medium (HNM) with 12 and 14% of salt. Above these salinity, the process still had 40% ammonium removal up to 20% of salt. Chromatography analysis validated the occurrence of the heterotrophic nitrif...

Ammonium removal from high-salinity oilfield-produced water: assessing the micr...

Water generated during oil exploration is chemically complex and contains high concentrations of ammonium and, in some cases, high salinity. The most common way to remove ammonium from effluent is a biological process, which can be performed by different routes and different groups of microorganisms. However, the presence of salts in the effluents could be an inhibiting factor for biological processes, interfer...

Applying functional metagenomics to search for novel lignocellulosic enzymes in...

Environments where lignocellulosic biomass is naturally decomposed are sources for discovery of new hydrolytic enzymes that can reduce the high cost of enzymatic cocktails for second-generation ethanol production. Metagenomic analysis was applied to discover genes coding carbohydrate-depleting enzymes from a microbial laboratory subculture using a mix of sugarcane bagasse and cow manure in the thermophilic comp...

DDetecção de genes que codificam naftaleno dioxigenase, tolueno dioxigenase e a...

Conselho Nacional de Desenvolvimento Científico e Tecnológico; Foram avaliados 14 isolados degradadores de petróleo, quanto à diversidade genética e à atividade catabólica dos mesmos e de cinco destes, em consórcio, no meio de cultivo adicionado de petróleo por meio da técnica de RT-PCR. A diversidade genética dos 14 isolados bacterianos foi avaliada por RAPD utilizando 12 oligonucleotídeos. O padrão de bandas ...
