Background. Microbial and fungal cellulases are known to hydrolyse cellulose, which is ingested as plant mate rial by herbivorous/omnivorous fishes. Microbial enzymes have enormous advantage of being produced in large quantities by established fermentation techniques. The present investigation aims to optimize the environmental and nutritional parameters for fermentation to enhance cellulase production by two bacterial strains isolated from fish gastrointestinal tracts. Materials and methods… 
Optimization of Culture Conditions for the Production of Extracellular Cellulase from Corynebacterium lipophiloflavum
Cellulase produced by Cornybacterium lipophiloflavum could efficiently remove dyes or inks from the pulp incubated either in the form of intact growing cell or with clarified supernatant suggesting the potential use of CornyBacteriumlipophil oflavum cellulase in industrial applications.
RSM based optimization of nutritional conditions for cellulase mediated Saccharification by Bacillus cereus
In this investigation, cellulase production of Bacillus cereus was explored while attacking poplar twigs and suggested potential utilization of this strain in biofuel industry.
Optimization of Culture Conditions for Production of Protease by Two Bacterial Strains, Bacillus licheniformis BF2 and Bacillus subtilis BH4 Isolated from the Digestive Tract of Bata, Labeo bata (Hamilton)
Beef extract as the nitrogen source was most effective in optimizing enzyme production by both the isolated strains, and the information generated from the present investigation will help to standardize the requirements for optimum production of protease by protease-producing fish gut bacteria.
Isolation, Screening, and Optimization of the Fermentation Conditions of Highly Cellulolytic Bacteria from the Hindgut of Holotrichia parallela Larvae (Coleoptera: Scarabaeidae)
From the hindgut contents of Holotrichia parallela, 93 cellulolytic bacterial isolates were isolated after enrichment in carboxymethyl cellulose medium. Among these isolates, a novel bacterium,
Optimization of Fermentation Conditions for Phytase Production by Two Strains of Bacillus licheniformis (LF1 and LH1) Isolated from the Intestine of Rohu, Labeo rohita (Hamilton)
The culture conditions for extracellular production of phytase by two strains of Bacillus licheniformis isolated from the proximal and distal intestine of rohu were optimized to obtain maximum level of phytic acid and enzyme production by these two strains were evaluated.
Highly Production of Cellulases Enzymes under Submerged State Fermentation for Agricultural Wastes Composting
Basal mineral salt medium amended with 1% rice straw was the best medium for cellulose-degrading enzymes production under submerged fermentation (SmF), and bagasse at 30% and urea at 2% were the best carbon and nitrogen sources, respectively.
Optimization of cellulase production for Bacillus sp. and Pseudomonas sp. soil isolates
Optimization of the fermentation medium for maximum cellulase production was carried out for both strains of 2b and 38b and a high cellulolytic activity was observed in Pseudomonas sp.
The present work was carried out to isolate the cellulose-decomposing bacteria (CDB) from Wadi El-Natrun, Egypt. Totally 40 isolates were isolated from saline mud samples. Eight out of 40 isolates
Isolation of potential novel cellulolytic and xylanolytic bacteria and optimization of their cultural conditions for enhanced production of cellulase and xylanase
Results indicated that favourable conditions and the selection of a suitable growth medium played a key role in the production of enzyme from newly isolated Bacillus licheniformis R2, Bacillus mojavensis .
The Influence of Temperature and Nitrogen Source on Cellulolytic Potential of Microbiota Isolated from Natural Environment
These experiments show that microorganisms isolated from natural environmental samples have unique properties and potential for commercial applications (e.g. for biopreparations production) and the optimal medium composition to achieve a simple, cost-efficient process of cellulases production was developed.


Enzyme producing bacterial flora isolated from fish digestive tracts
The study indicates that there is a distinct microbial source of the digestiveenzymes – amylase, cellulase, lipase and protease, apart from endogenoussources in fish gut, that might contribute towards better feed formulations for carp at low cost, incorporating the enzyme producing bacterial isolates as probiotics.
Influence of various fermentation variables on exo-glucanase production in Cellulomonas flavigena
During growth on α-cellulose containing 8-fold sodium nitrate concentration, maximum volumetric productivities of β-cellobiohydrolase and FPase were significantly higher than the values reported for some other potent fungi and bacteria.
Studies on cellulase production by Clostridium thermocellum
Xylan was degraded by an extracellular enzyme (s) produced during cultivation on cellobiose, although C. thermocellum does not grow on xylan, and an improved medium was devised for future studies.
