柱花草耐高温优质乳酸菌的筛选及对其青贮发酵品质的改善效果OA北大核心CSTPCD
Screening of high quality thermotolerant lactic acid bacteria in stylo and the improving effect on fermentation quality of its silage
为明确柱花草(Stylosanthes guianensis)青贮饲料中乳酸菌的耐高温情况及其对柱花草青贮品质的影响,采用传统微生物培养、分离、筛选结合 16s rRNA基因鉴定技术研究了柱花草青贮饲料中的主要耐高温优质乳酸菌种类与生理生化特性,并用筛选出的优质乳酸菌菌株接种柱花草调制青贮饲料.结果表明:从柱花草青贮饲料中筛选出了7 株可耐受 45℃高温、7.5%NaCl盐度、pH 4.5 酸度、至少可利用 11 种碳源、接种 2h后均能迅速产酸…查看全部>>
The objective of this experiment was to clarify the thermotolerant lactic acid bacteria in stylo silage and their effects on the quality of stylo silage,traditional microbial culture,isolation and screening.This was combined with 16s rRNA gene identification technology that was used to study the main species of high quality thermotolerant lactic acid bacterium in stylo silage and their physiological and biochemical characteristics.High quality lactic acid ba…查看全部>>
