ABSTRACT:
Four newPenicilliumspp. isolates (NRRL 21966, NRRL 21967, NRRL 21968, and NRRL 21969) are capable of essentially quantitative conversion of native alternan to a polymeric modified form having a lower apparent molecular weight than native alternan. A fifth isolate (NRRL 30489) obtained from a survey of deposited organisms and classified as aPenicilliumsubgenusBiverticilliumhas the same ability. The modified alternan has rheological properties similar to ultrasonicated alternan and is produced without the expense of ultrasonication. It would have utility as a substitute for gum arabic for uses such as bulking agents and extenders in foods and cosmetics.
