Cellulose degradation by a mixed bacterial culture
Tóm tắt
An integrated mixed bacterial culture consisting of four strains has been isolated by a batch enrichment technique. The cellulolytic member (strain D) is aCellulomonas sp. and the others are non-cellulolytic. The interaction between strains D and C is pronounced and appears to involve an exchange of reducing sugars and growth factors. The symbiotic relationship of this naturally occurring mixed culture is therefore one of mutualism. The filter paper cellulase and carboxymethyl cellulase activities in extracellular fluid are high, while β-glucosidase activity is low. The mixed culture digests a variety of lignocellulosics efficiently and is of fundamental interest in the study of microbial interrelationships.
