This study was aimed to screen and isolate thermophilic fungi from three selected compost wastes sites (Palm oil mill, Wood chip piles and Abattoir dump), and identify potential producers of lipases, cellulases and proteases respectively. The thermophilic fungi were obtained from an equal depth of one meter in all the three collection sites with a temperature range of 40 to 45OC and later cultured at 70 OC. F

Hydrolysis of lignocellulosic substrates is usually performed by enzymes produced and secreted by the fungus Trichoderma reesei. Studies identifying transcription factors involved in the regulation of cellulase production have been conducted but no overview of the whole regulation network is available.

Cellulosimicrobium sp. MP1 was isolated from termites gut, showing ability to biosynthesize cellulase including endoglucanase, exoglucanase, -glucosidase and xylanase and therefore is potential candidate for enzymatic saccharification of lignocellulosic material. The aim of this study is to investigate the ability of crude enzyme produced from Cellulosimicrobium sp. MP1 to hydrolyse the abundant lignocellulosic material in Viet Nam as straw.

In this study we examined diversity and activities of some actinomycetes isolated from mangroves in Giao Thuy, Nam Dinh Province. The distribution of actinomycetes in soil is strongly affected by external factors. Extra-cellular enzyme producing ability of mangrove actinomycetes is very high, particularly the ability of producing cellulase degrading filter paper (122/128 strains), CMC (110/128 strains), protease (83/128 strains) and amylase (78/128 strains).

Today, endophytic fungi have become new sources of industrially useful enzymes such as cellulases, chitinases, lipases, amylases and proteases. When endophytes reside on the plant surface, they produce enzymes to hydrolyze plant cell walls.

White radish (Raphanus sativus L.) is an edible root vegetable of the Brassicaceae family. It is cultivated and consumed all over the world. Nowadays, radishes are used and eaten by many people in their daily meals. Some studies showed that it has a high content of antioxidant compounds. In this study, we used enzyme - assisted extraction (EAE) to produce an antioxidant - rich extract. The antioxidant activity of the extract was determined by the ABTS radical cation scavenging capacity.

The major cellulase secreted by the filamentous fungus Trichoderma reeseiis cellobiohydrolase Cel7A. Its three-dimensional structure has been solved and various mutant enzymes produced. In order to study the potential use of T. reeseiCel7A in the alkaline pHrange, the thermal sta-bilityofCel7Awas studiedas a functionof pHwith thewild-type and two mutant enzymes using different spectroscopic methods. Tryptophan fluorescence and CD measurements of the wild-type enzyme show an optimal thermostability between pH3.5–5.

The cellobiohydrolase Pc_Cel7D is the major cellulase produced by the white-rot fungusPhanerochaete chrysosporium, constituting 10% of the total secreted protein in liquid culture on cellulose. The enzyme is classified into family 7 of the glycoside hydrolases and, like other family members, catalyses cellulose hydrolysis with net retention of the anomeric carbon configuration.

The basidiomyceteCoprinopsis cinereaproduces the glycoside hydrolase family 6 enzyme CcCel6C at low and constitutive levels. CcCel6C exhibits unusual cellobiohydrolase activity; it hydrolyses carboxymethyl cellulose, which is a poor substrate for typical cellobiohydrolases. Here, we deter-mined the crystal structures of CcCel6C unbound and in complex with p-nitrophenyl b-d-cellotrioside and cellobiose.
