The high concentration of lactic acid produced during the course of Lactobacillus kefiranofaciens fermentation inhibits kefiran production.Yeasts were cocultured with L.kefiranofaciens to improve kefiran production by consuming lactic acid to reduce the inhibition effect.The kefiran productivity of the coculture of L.kefiranofaciens and Saccharomyces cerevisiae under aerobic condition reached 94.19 mg/(L·h),53.7% higher than which of the pure culture.And the kefiran productivity of the coculture of L.kefiranofaciens and Candida utilis with the capability of glutathione production under aerobic condition reached 86.44 mg/(L.h),41.1% higher than which of the pure culture,especially another product,of glutathione also reached 250 mg/L by C.utilis.
