Abstract

Abstract: Alfalfa is difficult to ensile, while silage inoculants could improving alfalfa silage quality．This article mainly aims at screening silage inoculant Lactic Acid Bacteria that could quickly debase and stabilize pH value and producing more lactic acid．A continuous restricted cultivation was carried on until three kinds of Lactic Acid Bacteria had been selected from previously fermented juice and three kinds of Lactic Acid Bacteria had been selected from alfalfa silage. These six kinds of Lactic Acid Bacteria could cause the mediums’ pH value debase to around 3.2 in 72 hours and emitted sugary fragrance when they were cultured in MRS.

Key words: previously fermented juice; alfalfa silage; Lactic acid bacteria (LAB); selection; character
