| the acid phosphatases of thermoascus crustaceus, a thermophilic fungus. | thermoascus crustaceus, a filamentous, thermophilic ascomycete with pathogenic potential was cultured on sabouraud's liquid medium at temperatures from 27 to 47 degrees c for periods up to 7 days. growth rate and yield were optimal at 37 degrees c. morphological changes were confined to the cell walls, the thickness being greatest at 47 degrees c, which were also more resistant to mechanical disruption. significant amounts of acid phosphatase (ec 3.1.3.2) activity occurred in the spent media of ... | 1988 | 3173129 |
| a comparison of two xylanases from the thermophilic fungi thielavia terrestris and thermoascus crustaceus. | two thermophilic xylanases (xylanase ii from thielavia terrestris 255b and the 32-kda xylanase from thermoascus crustaceus 235e) were studied to determine if they had different and complementary modes of action when they hydrolysed various types of xylans. partial amino acid sequencing showed that these two enzymes belonged to different families of beta-1,4-glycanases. xylanase ii achieved faster solubilization of insoluble xylan whereas the 32-kda xylanase was more effective in producing xylose ... | 1993 | 7764332 |
| fungal survival during anaerobic digestion of organic household waste. | anaerobic digestion of organic waste yields energy rich biogas and retains nutrients (n, p, k, s, etc.) in a stabilised residue. for the residue to be used as a soil fertiliser, it must be free from pollutants and harmful microorganisms. fungal survival during sanitation and anaerobic treatment of source-separated organic household waste and during aerobic storage of the residue obtained was investigated. decimal reduction times were determined for inoculated fungi (aspergillus flavus and asperg ... | 2006 | 16293407 |
| colonization of peritoneal catheter with a thermophilic fungus, thermoascus crustaceus: a case report. | thermoascus crustaceus is a thermophilic fungus and the teleomorph form of paecilomyces crustaceus. thermoascus spp. have been rarely isolated from human mycoses as etiological fungal agents. we believe that our patient is the first case of catheter colonization with thermoascus crustaceus. in a 50-year-old male patient undergoing chronic peritoneal dialysis, the mold was isolated from three separate, consecutive dialysate fluid specimens and peritoneal catheter tip. the patient had slight clini ... | 2010 | 20446887 |
| metagenomic analysis of fungal diversity in korean traditional wheat-based fermentation starter nuruk. | nuruk, a traditional natural starter, is extensively used in the brewing of makgeolli, one of korea's most popular alcoholic beverages that has been recently gaining global popularity. thus, the quality of traditional nuruk needs to be enhanced. the nuruk mycobiome greatly influences both fermentation process as well as palatability enhancement. limitations of culture-dependent identification restrict an accurate analysis of fungal diversity and distribution in nuruks. 454 pyrosequencing of two ... | 2016 | 27554148 |
| identification and characterization of thermostable glucose dehydrogenases from thermophilic filamentous fungi. | fad-dependent glucose dehydrogenase (fad-gdh), which contains fad as a cofactor, catalyzes the oxidation of d-glucose to d-glucono-1,5-lactone, and plays an important role in biosensors measuring blood glucose levels. in order to obtain a novel fad-gdh gene homolog, we performed degenerate pcr screening of genomic dnas from 17 species of thermophilic filamentous fungi. two fad-gdh gene homologs were identified and cloned from talaromyces emersonii nbrc 31232 and thermoascus crustaceus nbrc 9129. ... | 2017 | 27510979 |
| determination of microbial diversity in daqu, a fermentation starter culture of maotai liquor, using nested pcr-denaturing gradient gel electrophoresis. | this study endeavored to investigate the diversity of microbes present during the shaping, ripening and drying of daqu, a fermentation starter culture and substrata complex of maotai alcoholic spirit. a nested pcr-denaturing gradient gel electrophoresis technique was utilized with different combinations of primers. the results showed the presence of bacteria, yeasts and molds. the microflora, which originate from wheat, were readily detectable during every stage of the fermentation process. howe ... | 2012 | 22806111 |
| autochthonous ascomycetes in depollution of polychlorinated biphenyls contaminated soil and sediment. | we investigated the capacity of a consortium of ascomycetous strains, doratomyces nanus, doratomyces purpureofuscus, doratomyces verrucisporus, myceliophthora thermophila, phoma eupyrena and thermoascus crustaceus in the mycoremediation of historically contaminated soil and sediment by polychlorinated biphenyls (pcbs). analyses of 15 pcb concentrations in three mesocosms containing soil from which the fungal strains had previously been isolated, revealed significant pcb depletions of 16.9% for t ... | 2014 | 24880600 |
| potential of autochthonous fungal strains isolated from contaminated soils for degradation of polychlorinated biphenyls. | up to now, most studies on polychlorinated biphenyl (pcb) bioremediation have examined the ability of model fungal strains to biodegrade pcbs. yet, there is limited information concerning the potential of autochthonous filamentous fungal strains in the biodegradation of pcbs and their possible use in the environmental technologies. in this study, we investigated the capacity of autochthonous fungal strains in the biodegradation of pcbs by isolating 24 taxa from former industrial sites highly con ... | 2013 | 23622721 |
| occurrence and ecological distribution of heat resistant moulds spores (hrms) in raw materials used by food industry and thermal characterization of two talaromyces isolates. | in this study, screening of some raw materials used to produce pasteurized products was carried out to determine the occurrence and ecological distribution of heat-resistant fungi. the search for heat resistant mould spores (hrms) resulted in the isolation of a limited number of fungal genera: arthrinium, aspergillus with either eurotium-type or neosartorya-type ascoma, byssochlamys, hyphodermella, monascus, penicillium, rasamsonia, talaromyces and thermoascus. sexual aspergilli constituted an o ... | 2017 | 27988465 |
| heat-resistance of hamigera avellanea and thermoascus crustaceus isolated from pasteurized acid products. | products containing sugar or fruit derivatives are usually subjected to a pasteurization process that can anyway be ineffective to kill ascospores from heat-resistant molds. although the most occurring and economically relevant heat-resistant species belong to byssochlamys, neosartorya, talaromyces, and eupenicillium genera, an increasing number of uncommon heat-resistant isolates have been recently detected as spoiling microorganisms in such products. since hamigera spp. and thermoascus spp. we ... | 2014 | 24239977 |
