Screening and Breeding of High CLA-Producing Strains by Mutation

Abstract

Abstract: In recent years, CLA has attracted strong interest in food science and madicine because some of the isomers are believed to have several beneficial effects. Anticarcinogenesis, antiarteriosclerosis, inhibition of body fat accumulation, growth and immune stimulation were inclued. Strains mutation happened by using ultraviolet, DNS, NTG, and their complex for promoting CLA level. The new strains of 315UU, 98DD, 1616UU and 71UN were obtained, and the ability of CLA production increased 43.04%～59.56% than before.

Key words: conjugated linoleic acid(CLA), Lactobacillus delbrueckii subsp. bulgaricus, mutation
