Spent brewer's yeast was autolysed and used as a raw material for the preparation of 5′-GMP-rich yeast extracts. Malt rootlets were used as a source of 5′-phosphodiesterase. The crude enzyme was extracted from malt rootlets and pretreated to inactivate 5′-nucleotidase. The optimum pretreatment conditions were heating at 65 °C for 30 min or 70 °C for 7 min. The effects of autolysis time, phosphodiesterase concentration and incubation period on 5′-GMP content were examined. The suitable autolysis… Expand
