Abstract: | Bacteria able to degrade pebble-milled filter paper cellulose (PMC) were detected in only two of five human faecal samples and at very low concentrations ( ca 100/g faeces). For another sample, the most probable number of cellulolytic organisms was 8·7 times 108/g with pebble-milled cell walls of New Zealand spinach as substrate, whereas PMC was not degraded. The cellulolytic bacteria isolated from those samples have been tentatively identified as atypical Ruminococcus spp. (two strains) and Eubacterium sp. A hemicellulolytic Butyrivibrio fibrisolvens was also isolated. |
