Cellulase activity measured as filter paper digesting activity (FPase) and carboxymethyl cellulase (CMCase) was demonstrated in hindgut extracts of the cockroach Periplaneta americana. The highest activities measured amounted to 0.89 and 0.12 U . ml for CMCase and FPase, respectively. The cellulolytic capacity of the hindgut population increased dramatically when protozoa were present, and the ...

The production of cellulolytic enzymes (β-exoglucanase, β-endoglucanase and β-glucosidase) by Penicillium sp. on three different media in liquid shake culture conditions was compared. The organism exhibited relatively highest activity of endoglucanase among three enzymes measured at 7-day interval during the course of its growth on Czapek-Dox medium supplemented with 0.5 % (w/v) cellulose. Cell...

Background: Enzyme production by solid state bioprocess (SSB) using residues as substrate for microorganisms is an alternative for costs reduction and to avoid their disposal into environment. The aim of this work was to evaluate the physiology of the fungus Lichtheimia ramosa in terms of microbial growth and production of amylases, β-glucosidases, carboxymethylcellulase (CMCase), and xylanases...

A method was developed for extracting enzymes from micro-organisms closely associated with ammonia-treated straw (NH3-S) that had been incubated in nylon bags in the rumen. Incubation of washed straw with 125 ml carbon tetrachloride/l and 20 micrograms lysozyme/ml for 3 h at 37 degrees gave carboxymethylcellulase (EC 3.2.1.4; CMCase) and NAD-linked glutamate dehydrogenase (EC 1.4.1.2; GDH) acti...

This study aimed to isolate and evaluate the cellulase activity of cellulolytic bacteria in hot springs of Dehloran, Ilam province, Iran. Water and sludge samples were collected from the hot springs and the bacterial enrichment was performed in a medium containing rice barn and carboxymethyl cellulose (CMC). The cultures were incubated at 50 °C in aerobic conditions. The bacteria were isolated ...

Carboxymethyl cellulase (CMCase) provides a key opportunity for achieving tremendous benefits of utilizing rice straw as cellulosic biomass. Out of total 80 microbial isolates from different ecological niches one bacterial strain, identified as Bacillus sp. 313SI, was selected for CMCase production under stationary as well as shaking conditions of growth. During two-stage pretreatment, rice str...

To utilize the plant nutrients efficiently, rumen microbes play a great role in livestock, acting as source of energy. Like other ruminants, yak harbours different microorganisms that are responsible for bioconversion into energy animals. The samples liquor were collected from (Bos grunniens) rumen. specific media was made to culture and isolated pure with serial dilution. colony identified hel...

Endophytic fungi inside a plant can degrade portion of lignin and cellulose. Penicillium is one the industrial microorganisms with advantage producing enzymes complete enzyme system that be secreted into extracellular space. The natural evolution ancient tree species from special geographic environments to screen out cellulase-producing strains excellent characteristics provides promising direc...
