[synthesis and secretion of the components of the cellulase complex in aspergillus terreus].aspergillus terreus was found to have two functionally different cellobiases. one of them is excreted into the surrounding medium and is a part of the cellulase complex. the second one is an endocellular (or periplasmic) enzyme. it is distinguished by its stability, the time of mrna operation, the sorption of cell debris; moreover, its activity does not depend on changes in the parameters of the medium when the incubation mixture is replaced and the surface is treated with 0.5 m nacl. the synthe ...19836413830
cellulolytic activity of moulds. iii. enzymatic hydrolysis of cellulose by cellulase preparation from aspergillus terreus f-413.the strain aspergillus terreus f-413 was used to obtain cellulolytic enzymes; it was cultivated on cellucotton by the submerged method in a 101 fermenter. the crude enzymatic preparation obtained from the post-culture liquid, containing small amounts of other enzymes besides active cellulases, was used for hydrolysis of several kinds of cellulose. the highest saccharification percentage was obtained with cellucotton and filter paper, while the lowest with lignocellulosic materials such as straw ...19846083705

lovastatin and simvastatin--inhibitors of hmg coa reductase and cholesterol biosynthesis.the microsomal enzyme 3-hydroxy-3-methylglutaryl coenzyme a (hmg coa) reductase is a key rate-controlling step early in the cholesterol biosynthetic pathway that catalyzes the conversion of hmg coa to mevalonic acid. since this enzyme plays a significant role in regulating cholesterol synthesis, it is a rational target for pharmacologic intervention. the first potent, specific inhibitor of hmg coa was mevastatin (compactin, ml-236b), which was discovered in 1976 by endo et al. [j antibiot 1976:2 ...19902073667

immunoreactivity of a 38-kilodalton penicillium marneffei antigen with human immunodeficiency virus-positive sera.penicillium marneffei produced and secreted a 38-kda antigen that appeared to be specific for this dimorphic fungus. this component could not be detected in antigenic extracts of histoplasma capsulatum, cryptococcus neoformans, aspergillus niger, aspergillus fumigatus, aspergillus flavus, aspergillus terreus, candida albicans, and two other species of penicillium by immunoblot analysis against the sera from patients with culture-confirmed penicilliosis marneffei. antibody reactive with this anti ...19979276391
multifocal aspergillus terreus discospondylitis in two german shepherd dogs.multifocal fungal (aspergillus terreus) discospondylitis was diagnosed in 2 german shepherd dogs. in one dog, the aetiology was established by means of fluoroscopic-guided disc aspiration, cytology and culture of disc material and urine. disseminated aspergillosis was confirmed at necropsy and a. terreus cultured from numerous organs in this dog. the aetiology in the other dog was not established until therapeutic failure forced surgical curettage of disc material from which the fungus was cultu ...19969284036
mevinolin: a highly potent competitive inhibitor of hydroxymethylglutaryl-coenzyme a reductase and a cholesterol-lowering agent.mevinolin, a fungal metabolite, was isolated from cultures of aspergillus terreus. the structure and absolute configuration of mevinolini and its open acid form, mevinolinic acid, were determined by a combination of physical techniques. mevinolin was shown to be 1,2,6,7,8,8a-hexahydro-beta, delta-dihydroxy-2,6-dimethyl-8-(2-methyl-1-oxobutoxy)-1-naphthalene-hepatanoic acid delta-lactone. mevinolin in the hydroxy-acid form, mevinolinic acid, is a potent competitive inhibitor of 3-hydroxy-3-methyl ...19806933445

diagnostic utility of thoracentesis for neutropenic children with cancer.thoracentesis is a procedure often performed in children with pleural effusions to assist in diagnosis and management. its safety and utility for immunocompromised patients with neutropenia (absolute neutrophil count, <1,500 polymorphonuclear leukocytes and band forms per microl) is unclear. we reviewed our experience over a 10-year period to evaluate the role of thoracentesis for neutropenic children with cancer who had pulmonary effusions of presumed infectious etiology. twenty-two patients we ...19958645835
itaconate biosynthesis in aspergillus terreus.itaconate biosynthesis was studied in intact cells of high-yield (rc4') and low-yield (cm85j) strains of the fungus aspergillus terreus by methods (tracers, nuclear magnetic resonance spectroscopy, and mass spectroscopy) that did not interfere with metabolism. itaconate formation in rc4' required de novo protein biosynthesis. krebs cycle intermediates increased in both strains during the production of itaconic acid. the embden-meyerhof-parnas pathway and the krebs cycle were shown to be involved ...19957768868
detection of aspergillus ribosomal rna using biotinylated oligonucleotide probes.aspergillosis continues to be a devastating disease entity that results in significant mortality in immunosuppressed patients. rapid diagnosis is often required to initiate appropriate therapy. although the histopathologist may be able to visualize fungal organisms in tissue specimens, the histology of aspergillus species may overlap with a variety of fungi, so diagnosis often relies on fungal cultures that can take weeks to complete. recently, an in situ hybridization assay targeting aspergillu ...19979458383

nondermatophyte causes of onychomycosis and superficial mycoses.compared to dermatophytes, nondermatophytes that may cause distal and lateral subungual onychomycoses are aspergillus species, acremonium species, fusarium oxysporum and scopulariopsis brevicaulis. white superficial onychomycosis may be caused by nondermatophyte species, for example, acremonium species, aspergillus terreus, other aspergillus species and fusarium oxysporum. nondermatophyte molds such as scopulariopsis brevicaulis may uncommonly result in cutaneous infections. scytalidium dimidiat ...19969504061
a new era of exploitation of microbial metabolites.in the past history of the pharmaceutical industry, secondary metabolites have been screened almost exclusively for antimicrobial activities. this biased and narrow view has severely limited the potential application of microbial metabolites. fortunately, this situation is changing and we are now entering into a new era in which microbial metabolites are being applied to diseases heretofore only subjected to synthetic compounds. this new approach is the application of microbial secondary metabol ...19836400479
