Abstract

The lactic acid bacteria (LAB) are much important for food processing industry and used as inoculants for silage preparation. The aim of the study was to isolate LAB from Italian ryegrass and investigates their growth and metabolite profiles in barley, corn, and Italian rye grass juice. We isolated number of the LAB, among these two isolates exhibited potent antifungal activity, and named as KCC-23 and KCC-24. Biochemical and 16S rRNA results revealed that the KCC-23 and KCC-24 as a Pediococcus pentosaceus and Lactobacillus plantarum respectively. The KCC-23 and KCC-24 showed significant growth in barley, corn and Italian ryegrass and MRS broth as compared with standard strains (KACC-91016 and KACC-91067). Also, KCC- 23 and KCC-24 produced the significant amount of lactic acid, succinic acid, and acetic acid. From the results, we concluded that the KCC-23 and KCC-24 could be useful for making quality silage from different grass and plants.
