Structure of the catalytic domain of glucoamylase from Aspergillus niger.
Glucoamylase from Aspergillus niger is an industrially important biocatalyst that is utilized in the mass production of glucose from raw starch or soluble oligosaccharides. The G1 isoform consists of a catalytic domain and a starch-binding domain connected by a heavily glycosylated linker region. The amino-terminal catalytic domain of the G1 isoform generated by subtilisin cleavage has been cry...
متن کاملEffect of maltose on glucoamylase formation by Aspergillus niger.
Low levels of glucoamylase are produced when Aspergillus niger is grown on sorbitol, but substitution of the latter by glucose, maltose, or starch results in greater formation of glucoamylase as measured by enzymatic activity. Both glucoamylase I and glucoamylase II are formed in a yeast extract medium; however, glucoamylase I appears to be the only form produced when ammonium chloride is the n...
متن کاملProduction of Glucoamylase by Aspergillus Niger under Solid State Fermentation
In this study, Glucoamylase production by Aspergillus niger was investigated under solid state fermentation using low cost by-products of agricultural processes as substrate. Highest enzyme production was observed when a combination of wheat bran (WB) and corn flour (CF) was used as compared to WB+ rice bran, WB+ rice flour and WB alone. Several compositions of corn flours were experimented. Th...
متن کاملBiotransformation of hinesol isolated from the crude drug Atractylodes lancea by Aspergillus niger and Aspergillus cellulosae.
Biotransformation of the sesquiterpene alcohol hinesol (1) with spasmolytic activity, which was prepared from the rhizome of Atractylodes lancea, was carried out by Aspergillus niger and Aspergillus cellulosae IFO 4040. Compound 1 was easily converted to compounds 2-9 by A. niger, and compounds 10 and 11 by A. cellulosae, respectively. Their stereostructures were established by a combination of...
متن کاملTHE PRODUCTION OF GLUCOAMYLASE BY ASPERGILLUS NIGER UNDER SOLID STATE CONDITIONS (RESEARCH NOTE)
In this study, Glucoamylase production by Aspergillus Niger was investigated under solid state conditions with low cost by-products of agricultural processes as substrate. Highest enzyme production was observed when a combination of wheat bran (WB) and corn flour (CF) was used as compared to WB+ rice bran, WB+ rice flour and WB alone. Different additions of (CF) were tested and WB+ 10% CF showe...
