Effective degradation of polychlorinated biphenyls by a facultative anaerobic bacterial consortium using alternating anaerobic aerobic treatments.

Polychlorinated biphenyls (PCBs) are synthetic mixtures of chlorinated hydrocarbon compounds that were widely used in the past and still found in the environment due to their highly recalcitrant nature. A combination of anaerobic dechlorination and aerobic oxidation is essential to degrade these PCB mixtures into less toxic products. It was hypothesized that due to the complexity of PCB mixtures, a consortium of carefully selected suitable microbial species will perform better than the application of individual microbes.

Co-utilization of acidified glycerol pretreated-sugarcane bagasse for microbial oil production by a novel strain.

Acidified glycerol pretreatment is very effective to deconstruct lignocellulosics for producing glucose. Co-utilization of pretreated biomass and residual glycerol to bioproducts could reduce the costs associated with biomass wash and solvent recovery. In this study, a novel strain RP 15, isolated from sugarcane bagasse, was selected and tested for coconversion of pretreated biomass and residual glycerol to microbial oils.

Solubilization and degradation of polychlorinated biphenyls (PCBs) by naturally occurring facultative anaerobic bacteria.

A combination of solubilization and degradation is essential for the bioremediation of environments contaminated with complex polychlorinated biphenyls (PCB) mixtures. However, the application of facultative anaerobic microorganisms that can both solubilize and breakdown hydrophobic PCBs in aqueous media under both anaerobic and aerobic conditions, has not been reported widely. In this comprehensive study, four bacteria discovered from soil and sediments and identified as Achromobacter sp.

A proteomic view into infection of greyback canegrubs (Dermolepida albohirtum) by Metarhizium anisopliae.

Metarhizium anisopliae is a naturally occurring cosmopolitan fungus infecting greyback canegrubs (Dermolepida albohirtum). The main molecular factors involved in the complex interactions occurring between the greyback canegrubs and M. anisopliae (FI-1045) were investigated by comparing the proteomes of healthy canegrubs, canegrubs infected with Metarhizium and fungus only.
