Purification and Characterization of an Endo-(1,3)-beta-d-Glucanase from Trichoderma longibrachiatum.
A laminarinase [endo-(1,3)-beta-d-glucanase] has been purified from Trichoderma longibrachiatum cultivated with d-glucose as the growth substrate. The enzyme was found to hydrolyze laminarin to oligosaccharides varying in size from glucose to pentaose and to lesser amounts of larger oligosaccharides. The enzyme was unable to cleave laminaribiose but hydrolyzed triose to laminaribiose and glucos...
متن کاملPurification and characterization of an endo-1,3-β-glucanase from Arthrobacter sp
An endo-1,3-β-glucanase from Arthrobacter sp. was purified by ammonium sulfate precipitation, anion-exchange and gel-filtration chromatographies. SDS/PAGE and gel-filtration chromatography suggested a monomer enzyme with molecular mass of 32,500. N-terminal sequence for 10 residues was APGDLLWSDE. Stable and optimum pHs were 5 to 8 and 6.5, respectively. Optimum temperature was 55°C , however, ...
متن کاملPurification and characterization of an endo-beta-1,6-glucanase from Trichoderma harzianum that is related to its mycoparasitism.
The enzymes from Trichoderma species that degrade fungal cell walls have been suggested to play an important role in mycoparasitic action against fungal plant pathogens. The mycoparasite Trichoderma harzianum produces at least two extracellular beta-1,6-glucanases, among other hydrolases, when it is grown on chitin as the sole carbon source. One of these extracellular enzymes was purified to ho...
متن کاملIsolation, Purification and Characterization of Glucanase Enzyme from the Antagonistic Fungus Trichoderma
Glucanase enzyme isolated from Trichoderma isolates were purified to homogeneity using ammonium persulphate precipitation and Fast Protein Liquid Chromatography. Purity of the isolated enzyme was confirmed by SDS-PAGE. Enzymatic properties such as effect of temperature, pH, SDS and EDTA were determined. Molecular weight of Trichoderma isolates was found to be around 55 kDa. The optimum temperat...
متن کاملCrystal structure of endo-1,4-β-glucanase from Eisenia fetida
The saccharification process is essential for bioethanol production from woody biomass including celluloses. Cold-adapted cellulase, which has sufficient activity at low temperature (<293 K), is capable of reducing heating costs during the saccharification process and is suitable for simultaneous saccharification and fermentation. Endo-1,4-β-glucanase from the earthworm Eisenia fetida (EF-EG2) ...
