Production of hydrolytic enzymes by the plant pathogenic fungus Myrothecium verrucaria in submerged cultures

Production of Hydrolytic Enzymes by the Plant Pathogenic Fungus Myrothecium Verrucaria in Submerged Cultures

The capability of the plant pathogenic fungus Myrothecium verrucaria to produce extracellular hydrolytic enzymes in submerged cultures was studied using several substrates. The fungus was able to produce different depolymerases and glycosidases, being xylanase, pectinase and protease the most important. Lipase was found in cultures developed in the presence of olive oil, while protease activity...

Enzyme-Linked Immunosorbent Assay Detection of Trichothecenes Produced by the Bioherbicide Myrothecium verrucaria in Cell Cultures, Extracts, and Plant Tissues

A rapid technique for trichothecene detection was needed in screening tests of the potential bioherbicide Myrothecium verrucaria (MV), in order to select strains, mutants, or formulations that were void of or that possessed low amounts of these undesirable mycotoxin compounds. Commercially available enzymelinked immunosorbent assay (ELISA) plates for trichothecene detection, possessing cross-re...

Constitutive and induced trehalose transport mechanisms in spores of the fungus Myrothecium verrucaria.

Trehalose is absorbed by two distinct systems-one constitutive, the other induced by turanose and to a lesser extent by nigerose but not by trehalose. The constitutive system is apparently mediated by a surface trehalase; the induced system has the characteristics of a permease. The specificity of the induced system is apparently limited to the alpha glucosyl-glucose or glucosyl-fructose linkag...

Trehalose as an endogenous reserve in spores of the fungus Myrothecium verrucaria.

Mandels, G. R. (U.S. Army Natick Laboratories, Natick, Mass.), Rasma Vitols, and Frederick W. Parrish. Trehalose as an endogenous reserve in spores of the fungus Myrothecium verrucaria. J. Bacteriol. 90:1589-1598. 1965.-Gross analysis of Myrothecium verrucaria spores showed approximately 3% fat, 33% carbohydrate, and 9.5% nitrogen. The water-soluble carbohydrates were trehalose, glucose, mannit...
