Enhanced cellulase production by a mutant of Trichoderma viride.
A mutant strain that secretes twice as much cellulase as its parent was obtained by irradiating conidia of Trichoderma viride QM 6a with a linear accelerator.
متن کاملCellulase Production by Trichoderma viride on Feedlot Waste.
Feedlot waste contains essentially all the necessary nutrients for batch fermentation with the fungus Trichoderma viride. The organism utilizes two-thirds of the carbohydrate in feedlot waste while elaborating cellulase in quantities comparable to commercial preparations. Essentially odor-free, the fermented waste contains all of the original nitrogen but has 24% less organic matter.
متن کاملThermal Degradation of Cellulosic Materials
Fortisan, cellulose triacetate, and NOroxidized cellulose were pyrolyzed in a vacuum in the temperature range 1800 to 465 0 C. Cotton cellulose and cellulose t ri acetate were also pyrolyzed in nitrogen at atmospheric pressure. The tar yields were in the decreasing order from: Cotton, Fortisan, cellulose triacetate, and oxidized cellulose. The other volatiles consisted mainly of acetic acid, ca...
متن کاملEnhanced cellulase production of the Trichoderma viride mutated by microwave and ultraviolet.
Cellulase-producing fungi Trichoderma viride were cultured and fermented on the solid-state wheat bran fermentation medium. The characteristics of its carboxymethyl cellulase (CMCase) in the condition of this solid-state fermentation were evaluated, and the optimum culture time, optimum pH and optimum temperature for CMCase activity of T. viride fermented in this solid state were 60h, 5.0 and 5...
متن کاملInduction of cellulase in Trichoderma viride as influenced by carbon sources and metals.
Cellulase is an adaptive enzyme in most fungi (Reese and Levinson, 1952), although it is constitutive in cellulolytic bacteria (Hammerstrom et al., 1955). Many polysaccharases are adaptive in fungi, including: pentosanase (Simpson, 1954), polygalacturonase (Phaff, 1947), chitinase (Reynolds, 1954), dextranase (Hultin and Nordstr6m, 1949), and xylanase and mannanase (S0rensen, 1952). Since many ...
