The production of extracellular amylase was investigated employing our laboratory isolate, Aspergillus niger sp. MK 07 and effect of process variables on enzyme production, was studied in a fermentor. It was found that amylase production was maximum when the fermentor
Acid hydrolyzates of waxy-maize starch were separated to give Fractions I, II, and III [T. Watanabe, and D. French, Carbohydr. Res., 84 (1980) 115-123]. Watanabe and French suggested that Fraction II, which contains approximately 25 D-glucose residues including an alpha-D-(1----6)-linked
Amylose (average d.p. 1000) and amylodextrin (average d.p. 25) have identical 13C-n.m.r. spectra, except for some minor signals from the small amount of alpha-1----6 branch linkages present in amylodextrin. Amylodextrin can be obtained as stable solutions in much higher concentrations
Amylodextrin is a linear dextrin and can be produced by enzymatic hydrolysis of the alpha-1,6 glycosidic bonds of amylopectin. Tablets compacted from pure amylodextrin showed good binding properties and did not disintegrate in aqueous media. Extended and decreasing drug release
Amylodextrin is a suitable excipient for the design of solid controlled-release systems. The release of paracetamol from tablets containing 30% drug and 70% amylodextrin was studied in vitro and in vivo. In vitro dissolution profiles showed almost-constant drug release rates
