Six strain of Trichoderma (T. viride, T. harzianum, T. reesei, T. longibrachiatum, T. koningii, T. virens) were isolated and used for extracellular enzyme production. Species of Trichoderma are collected from the surrounding soil of suger beet root fields in East Iran, and held in vitro cultured PDA. TCM and TFM are used for the growth of spores and induceing the production of Cellulase. Finall...

BACKGROUND Members of the bacterial genus Caldicellulosiruptor are the most thermophilic cellulolytic organisms described to date, and have the ability to grow on lignocellulosic biomass without conventional pretreatment. Different species vary in their abilities to degrade cellulose, and the presence of CelA, a bifunctional glycoside hydrolase that contains a Family 48 and a Family 9 catalytic...

Candida albicans is the major fungal pathogen of humans. Its adhesion to host-cell surfaces is the first critical step during mucosal infection. Antimicrobial peptides play important roles in the first line of mucosal immunity against C. albicans infection. LL-37 is the only member of the human cathelicidin antimicrobial peptide family and is commonly expressed in various tissues, including epi...

The mangrove ecosystem is an unexplored source for biotechnological applications. In this unique environment, endemic bacteria have the ability to thrive in the harsh environmental conditions (salinity and anaerobiosis), and act in the degradation of organic matter, promoting nutrient cycles. Thus, this study aimed to assess the cellulolytic activities of bacterial groups present in the sedimen...

A total of 10 cellulase-producing bacteria were isolated from soil samples irrigated with paper and pulp mill effluents. The sequencing of 16S rRNA gene revealed that all isolates belonged to different species of genus Bacillus. Among the different isolates, B. subtilis IARI-SP-1 exhibited a high degree of β-1,4-endoglucanase (2.5 IU/ml), β-1,4-exoglucanase (0.8 IU/ml), and β-glucosidase (0.084...

1. Four principal endoglucanase components of Trichoderma koningii cellulase were separated and purified by gel filtration on Sephadex G-75, ion-exchange chromatography on DEAEand sulphoethyl-Sephadex and isoelectric focusing. 2. All four endoglucanases hydrolysed CM-cellulose, H3PO4-swollen cellulose, cellotetraose and cellopentaose, but differed in the rate and mode of attack. 3. Attack on co...
