species-specific production of microbial volatile organic compounds (mvoc) by airborne fungi from a compost facility.thirteen airborne fungal species frequently isolated in composting plants were screened for microbial volatile organic compounds (mvoc), i.e., aspergillus candidus, a. fumigatus, a. versicolor, emericella nidulans, paecilomyces variotii, penicillium brevicompactum, penicillium clavigerum, penicillium crustosum, penicillium cyclopium, penicillium expansum, penicillium glabrum, penicillium verruculosum, and tritirachium oryzae. air samples from pure cultures were sorbed on tenax gr and analyzed by ...199910448558
study of protein adsorption on indigo particles confirms the existence of enzyme--indigo interaction sites in cellulase molecules.adsorption of several crude and purified cellulases (from trichoderma reesei, penicillium verruculosum and chrysosporium lucknowense) on indigo particles and avicel cellulose was studied. much higher amounts of protein were bound to indigo than to cellulose under similar conditions. for different purified enzymes, the quantity of bound protein per mg of adsorbent (indigo or cellulose) varied in the range of 57-111 and 0-62 microg x mg(-1), respectively. however, in general, the enzyme adsorption ...200111267701
[isolation and properties of cellobiase from penicillium verruculosum].cellobiase (beta-d-glucosidase) with a molecular weight of 100 kda and pi 5.2 was isolated from the cellulolytic system of penicillium verruculosum. kinetic parameters of enzymatic hydrolysis of cellobiose, gentiobiose, sophorose, and synthetic substrates, i.e. methylumbelliferyl and p-nitrophenyl sugar derivatives were determined. glucose and d-glucose-delta-lactone competitively inhibited cellobiase (ki = 0.19 mm and 17 microm, respectively). glucosyl transfer reactions were studied with cello ...200111771322
[studies of hydrolytic activity of enzyme preparations of penicillium and trychoderma fungi].enzyme preparations were isolated from the culture liquid of five mutant strains of the cellulase producer penicillium verruculosum. the hydrolytic activities of these preparations against unbleached eucalypt cellulose was compared to that of commercial preparations of trichoderma reesei (t. longibrachiatum). in the majority of cases, p. verruculosum enzymes provided higher yields of reducing sugars (rss) and glucose. a correlation was found between the yield of rss and the avicelase activity of ...200515859466
[the selection and properties of penicillium verruculosum mutants with enhanced production of cellulases and xylanases].the paper describes three penicillium verruculosum 28k mutants with about threefold enhanced production of five industrially important carbohydrases. the two-stage fermentation process that we developed provided a further two- to threefold increase in the production of carbohydrases. physiological and biochemical studies showed that the synthesis of all five carbohydrases is inducible. carboxymethylcellulase, xylanase, and beta-glucanase are synthesized under a common regulatory control, as is e ...200515938392
design of highly efficient cellulase mixtures for enzymatic hydrolysis of cellulose.an extremely highly active cellobiohydrolase (cbh iib or cel6b) was isolated from chrysosporium lucknowense uv18-25 culture filtrate. the cbh iib demonstrated the highest ability for a deep degradation of crystalline cellulose amongst a few cellobiohydrolases tested, including c. lucknowense cbh ia, ib, iia, and trichoderma reesei cbh i and ii. using purified c. lucknowense enzymes (cbh ia, ib, and iib; endoglucanases ii and v; beta-glucosidase, xylanase ii), artificial multienzyme mixtures were ...200717221887

Production of cellulase enzymes during the solid-state fermentation of empty palm fruit bunch fiber.Penicillium verruculosum COKE4E is a fungal strain isolated from bituminous coal. The microorganism cultivated in a minimal medium supplemented with Avicel, carboxymethylcellulose, and oat spelt xylan produced cellulase enzymes as exhibiting carboxymethylcellulase (CMCase), Avicelase, xylanase, and cellobiosidase activities. In this study, the productivity of the extracellular enzymes in the strain was evaluated by using empty palm fruit bunch fiber (EPFBF), a lignocellulosic biomass, as a subst ...201122052232
