fungal air spora at ibadan, nigeria.	the fungal air spora at ibadan, nigeria, was investigated by using casella slit samplers. three sites, incorporating three locations at each site, were selected for the exposure of replicate plates during sampling. to provide data on a wide range of saprophytic and pathogenic fungal spores, isolations were made on sabouraud dextrose agar and malt agar plates incubated at 26 and 37 c. altogether over 60,000 fungal colonies were isolated and counted during the 12-month sampling period. the prevale ...	1975	1124919
biosynthesis, purification and some properties of extracellular phytase from aspergillus carneus.	aspergillus carneus (van tiegh) blockwitz synthesized moderate quantities of phytase in culture filtrate. maximal enzyme yield was obtained after eight days incubation statically in a medium containing sucrose and k2hpo4 in a c/p ratio of 591.8/1 with 0.1% corn steep liquor (csl) as the sole source of nitrogen. substitution of (nh4)2so4 with certain amino acids decreased phytase yields significantly. addition of fish or soybean meal to the nitrogen-free medium failed to enhance phytase productio ...	1990	2176769

microbial degradation of trifluralin by aspergillus carneus, fusarium oxysporum and trichoderma viride.	3h-trifluralin was synthesized by condensation of 3h-4-chloro-3,5-dinitro-alpha, alpha, alpha-trifluorotoluene with di-n-propylamine. after incubation of trifluralin with aspergillus carneus, fusarium oxysporum and trichoderma viride for 10 days, a small percentage (less than 10%) of unchanged herbicide was recovered in the extractable fraction. this indicates a fairly rapid degradation of the herbicide by the fungal species. other than trifluralin, the culture medium contained at least five lab ...	1983	6682873
potential use of a novel lipase from aspergillus carneus in deacetylation reactions.	a novel lipase from aspergillus carneus has been used in organic solvents for efficient regioselective and chemoselective deacetylation of the peracetates of polyphenolic aromatic ketones, esters and amides. a reversal of regioselectivity was observed as compared with the results obtained during deacetylation with porcine pancreatic lipase (ppl).	1998	9748644
aspergillicins a-e: five novel depsipeptides from the marine-derived fungus aspergillus carneus.	a search for new antiparasitic agents from a strain of the fungus aspergillus carneus isolated from an estuarine sediment collected in tasmania, australia, yielded the known terrestrial fungal metabolite marcfortine a (1) as an exceptionally potent antiparasitic agent. this study also yielded a series of new depsipeptides, aspergillicins a-e (2-6) and the known terrestrial fungal metabolite acyl aszonalenin (7). marcfortine a (1) and acyl aszonalenin (7) were identified by spectroscopic analysis ...	2003	12945765
evolutionary relationships among aspergillus terreus isolates and their relatives.	aspergillus terreus is a ubiquitous fungus in our environment. it is an opportunistic human pathogen and economically important as the main producer of lovastatin, a cholesterol lowering drug. our aim was to examine the genetic variability of a. terreus and closely related species using molecular and analytical techniques. lovastatin production was examined by hplc. lovastatin was produced by seven isolates belonging to the species a. terreus. rapd analyses were carried out using 25 different ra ...	2005	16096690
[extracellular proteolytic eyzymes of microscopic fungi from thermal springs of the barguzin valley (northern baikal region)].	production of extracellular proteolytic enzymes was studied in thermophilic fungi paecelomyces variotii and aspergillus carneus, isolated from thermal springs of the barguzin valley. protease synthesis in these fungi requires protein in the ambient medium. the composition of the enzymes secreted by a. carneus depends on the kind of carbohydrate present in the medium. the proteinase of this fungus digests synthetic substrates and gelatin (optimum ph 7.7). it belongs to neutral serine proteases. e ...	2006	16761576
enhanced production of xylanase by aspergillus carneus m34 in solid-state fermentation with agricultural waste using statistical approach.	the production of a low molecular weight xylanase by aspergillus carneus m34 was investigated in solid-state fermentation using agricultural waste as the substrate. experimental designs were practiced for optimisation of the medium composition. when agricultural wastes of coba husk and corn steep liquor were used in the ratio of 4.5:0.5, a 22.5% increase of xylanase activity was observed compared with the medium containing only coba husk. the incubation time for xylanase production can be reduce ...	2010	19800041
