| screening of aspergillus species for occurrence of lectins and their characterization. | ten species of aspergillus were screened for occurrence of lectins. each of the species was investigated for the occurrence of extracellular, surface-bound and intracellular lectin activities. as many as four species namely, aspergillus niger, aspergillus versicolor, aspergillus rugulosus and aspergillus nidulans, were found to possess intracellular lectin activities, while none of the species showed extracellular or surface-bound lectin activities. each of the lectin was characterized with resp ... | 2008 | 18383222 |
| pectinase production by solid fermentation from aspergillus niger by a new prescription experiment. | the ordos plateau in china is covered with up to 300,000 ha of peashrub (caragana) which is the dominant natural vegetation and ideal for fodder production. to exploit peashrub fodder, it is crucially important to optimize the culture conditions, especially culture substrate to produce pectinase complex. in this study, a new prescription process was developed. the process, based on a uniform experimental design, first optimizes the solid substrate and second, after incubation, applies two differ ... | 2006 | 16406599 |
| release of volatile branched-chain and other fatty acids from ruminant milk fats by various lipases. | bovine, ovine, and caprine milk fats were treated with pregastric lipases (kid goat, calf, and lamb), microbial lipases (candida cylindracea, c. cylindracea ay30, aspergillus niger apf12, rhizopus arrhizus, penicillium roqueforti r10, and mucor zavanicus map 10), porcine pancreatic lipase, or milk lipase. all three pregastric lipases preferentially hydrolyzed volatile branched-chain and short n-chain fatty acids from each milk fat. pregastric lipases also released a relatively low proportion of ... | 1993 | 8463483 |
| determining the kinetic behaviour for the secretion of milk toxin as related to dosage level of aflatoxin b1. | 39 species which belong to 14 genera were isolated from 110 milk samples collected from different dairy sources at assiut city. the most frequent fungi were a. niger, a flavus and clasdosporium cladosporioides, followed by curvularia spicifera and penicillium corylophilum. the remaining species were of rare occurrence. the fluorescence-method for detecting aflatoxin-producing strains demonstrated the presence of two isolates namely a. flavus possesses this property. one of these toxic isolates w ... | 1981 | 6794233 |
