Focused Metabolism of β-Glucans by the Soil Bacteroidetes Species Chitinophaga pinensis.

ABSTRACT: The genome and natural habitat of Chitinophaga pinensis suggest it has the ability to degrade a wide variety of carbohydrate-based biomass. Complementing our earlier investigations into the hydrolysis of some plant polysaccharides, we now show that C. pinensis can grow directly on spruce wood and on the fungal fruiting body. Growth was stronger on fungal material, although secreted enzyme activity was high in both cases, and all biomass-induced secretomes showed a predominance of β-glucanase activities. We therefore conducted a screen for growth on and hydrolysis of β-glucans isolated from different sources. Most noncrystalline β-glucans supported good growth, with variable efficiencies of polysaccharide deconstruction and oligosaccharide uptake, depending on the polysacchari
