PP-6 isolated from Tibetan Plateau could ferment raffinose , lactose , sorbitol , melibiose and sucrose , and LS-5 could ferment cottonseed sugar , laetrile , rhamnose , lactose , sorbitol , xylose , arabinose , melibiose and sucrose , but the same species of commercial strains could not use these sugars .
[Effect of lactic acid bacteria isolated from Tibetan Plateau on silage fermentation quality of Elms nutans]. In order to detect the effect of lactic acid bacteria isolated from Tibetan Plateau on silage fermentation quality of Elms nutans. ### methods We used 3 isolated lactic acid bacteria with better growth at low temperatures of 10 and 15 degrees C at ensiling of Elymus nutans. Subsequently, effects of the selected lactic acid bacteria on fermentation profiles of Elymus nutans silages stored at 15 and 25 degrees C were evaluated by using the same species of commercial inoculants as the control. ### results PP-6 isolated from Tibetan Plateau could ferment raffinose , lactose , sorbitol , melibiose and sucrose , and LS-5 could ferment cottonseed sugar , laetrile , rhamnose , lactose , sorbitol , xylose , arabinose , melibiose and sucrose , but the same species of commercial strains could not use these sugars . Inoculation of these three strains into Elymus nutans at 15 and 25 degrees C ensiled for 50 d, we found that LS-5 significantly reduced silage pH, propionic acid concentration and ratio of ammonia nitrogen/total nitrogen at 15 degrees C (P < 0.05), salvaged more water-soluble carbohydrate and crude protein; Application of LP-2 and PP-6 as a combined inoculant to Elymus nutans significantly improved lactic acid concentration (P < 0.05), resulting in a lower ratio of ammonia nitrogen/total nitrogen, saved more crude protein and significantly reduced neutral detergent fiber content (P < 0.05) as compared with the commercial strains. ### conclusion The three isolated strains can improve silage quality of Elymus nutans growing on the Qinghai-Tibetan Plateau at low temperature, but these strains have no obvious advantages at 25 degrees C in comparison with the commercial inoculants.
