Community-intrinsic properties enhance keratin degradation from bacterial consortia

Comparative Studies on Bacterial Consortia for Hydrocarbon Degradation

Abstract:Globally environmental scientists have shown increased interest in promoting biological methods referred to as “Green technology” in the clean-up technologies for hydrocarbon-polluted sites. These methods are less expensive and do not introduce additional chemicals/pollutants into the environment. Compared to physico-chemical methods, bioremediation / biodegradation offer a feasible al...

Determination of keratin degradation by fungi using keratin azure.

Azure dye-impregnated sheep's wool keratin (keratin azure) was incorporated in a high pH medium and overlaid on a keratin-free basal medium. The release and diffusion of the azure dye into the lower layer indicated production of keratinase. Fifty-eight fungal taxa, including 49 members of the Arthrodermataceae, Gymnoascaceae and Onygenaceae (Order Onygenales), were assessed for keratin degradat...

Developing AIDS community service consortia.

Succession of lignocellulolytic bacterial consortia bred anaerobically from lake sediment

Anaerobic bacteria degrade lignocellulose in various anoxic and organically rich environments, often in a syntrophic process. Anaerobic enrichments of bacterial communities on a recalcitrant lignocellulose source were studied combining polymerase chain reaction-denaturing gradient gel electrophoresis, amplicon sequencing of the 16S rRNA gene and culturing. Three consortia were constructed using...

Substrate Shift Reveals Roles for Members of Bacterial Consortia in Degradation of Plant Cell Wall Polymers

Deconstructing the intricate matrix of cellulose, hemicellulose, and lignin poses a major challenge in biofuel production. In diverse environments in nature, some microbial communities, are able to overcome plant biomass recalcitrance. Identifying key degraders of each component of plant cell wall can help improve biological degradation of plant feedstock. Here, we sequenced the metagenome of l...
