- A microbial consortium with a high cellulolytic activity was enriched to degrade raw corn stover powder
(RCSP). This consortium degraded more than 51% of non-sterilized RCSP or 81% of non-sterilized filter
paper within 8 days at 40 ℃ under facultative anoxic conditions. Cellulosome-like structures were
observed in scanning electron micrographs (SEM) of RCSP degradation residue. The high cellulolytic
activity was maintained during 40 subcultures in a medium containing cellulosic substrate. Small ribosomal
gene sequence analyses showed the consortium contains uncultured and cultured bacteria with
or without cellulolytic activities. Among these bacteria, some are anaerobic others aerobic. Analyses of
the culture filtrate showed a typical anoxic polysaccharide fermentation during the culturing process.
Reducing sugar concentration increased at early stage followed by various fermentation products that
were consumed at the late stage.
