Ale beer containing free and immobilized Lactobacillus brevis, a potential delivery system for probiotics
Abstract Probiotics in ale beer may be attractive to health-conscious consumers. However, beer conditions may decrease probiotic viability. Powder produced from durian (Durio zibethinus) rind, a by-product that is currently unutilized, can be used for the immobilization of probiotics. MRS medium was...
