Distribution of cellulases in the body of Coptotermes formosanus and the probability that the termite uses glucose as an energy and carbon sources
1997 - IRG/WP 97-10202
We assayed extracts of the digestive system and of the whole body of Coptotermes formosanus to determine where the various cellulases, glucose, and related substances were concentrated and to detect pyruvate dehydrogenase activity in the hindgut-removed body in order to verify its full cellulolytic system. About 20%, 18% and 36% of the total exo-1,4-ß-glucanase activity of C. formosanus were dete...

Comparative study of the degradative ability of autochthonous and standardized strains of wood decay fungi
1996 - IRG/WP 96-10178
This study is intended to assess the biomass, the extracellular protein production, and the carbohydrate degradating ability of three standarized (Chaetomium globosum, Trametes versicolor and Gloeophyllum trabeum) and six autochthonous wood decay fungi strains, with unknown degradating effects. The carbohydrate sources used were those that are usually found in wood cells (glucose, galactose, manos...

The identification of the carbohydrate degrading enzymes from the crude extract of brown-rot fungus Gloeophyllum trabeum
1991 - IRG/WP 1483
The brown-rot fungus, Gloeophyllum trabeum, produces a pattern of carbohydrate degrading enzymes during the wood decay. In liquid sawdust media the activities of endo-b-1,4-gluganase and endo-b-1,4-xylanase were at the maximum after 5-6 weeks cultivation. The production of enzymes started immediately after inoculation suggesting that the degradation of hemicellulose and easily degradable parts of ...
