DIVERSITY OF CELLULOLYTIC BACTERIA ISOLATED FROM A FRESHWATER WETLAND RESERVE IN THAILAND AND THEIR CELLULOLYTIC ACTIVITY

Cellulolytic and non-cellulolytic bacteria in rat gastrointestinal tracts.

Lactobacillus and Bifidobacterium species were the predominant organisms isolated from small intestinal (jejunal) contents of rats, and lactic acid was the only organic acid detected. The numbers of cellulolytic bacteria in small intestines were low (approximately 10(3)/g). The fermentation in ceca was different from that in intestines, as, in addition to small amounts of lactic acid, high conc...

Isolation of Cellulolytic Bacteria

Cellulolytic activity and structure of symbiotic bacteria in locust guts.

Locusts are able to digest the cellulose of Gramineae plants, resulting in their being considered as major crop pests. To illustrate the mechanism involved in cellulose digestion, the cellulolytic activity and zymography in the gut contents of 16 locust species were determined using carboxymethyl cellulose (CMC) as substrate. The diversity of gut symbiotic bacteria was studied using denaturing ...

Competition among three predominant ruminal cellulolytic bacteria in the absence or presence of non-cellulolytic bacteria.

Competition among three species of ruminal cellulolytic bacteria - Fibrobacter succinogenes S85, Ruminococcus flavefaciens FD-1 and Ruminococcus albus 7 - was studied in the presence or absence of the non-cellulolytic ruminal bacteria Selenomonas ruminantium or Streptococcus bovis. Co-cultures were grown under either batch or continuous conditions and populations were estimated using species-sp...

Qualitative Display and Measurement of Enzyme Activity of Isolated Cellulolytic Bacteria

Cellulase is the key enzyme in the bio refinery process of producing green chemicals. As cellulase production cost is the major factor in these processes, there is lot of need to isolate the effective producers of cellulase from the natural environment which can degrade the abundantly available lignocellulose materials. Congo red clearing zone assay, gel diffusion assay and dyed congo red filte...
