Notes:
The influence of concentrated maltotetraose solutions on fungal alpha-amylase activity and specificity has been determined. It has been found that the enzyme is not inhibited by 500 g/L substrate concentration and that transglycosylation reactions are increased with rising substrate concentration. The amount of oligosaccharides of polymerization degree higher than maltotetraose reaches 20% (w/w). Moreover, the effect of polyhydric alcohols, known as water activity depressors has been analyzed: the presence of polyols does not modify the amount of transglycosylation products, but changes the hydrolysis pattern by favoring the formation of low polymerization degree oligosaccharides.
