概括
丁菌 (Lentilactobacillus buchneri) 的注射通过减少氨和增加酸和体外消化能力,改善了S. perfoliatum料发酵. 在料生产方面,L. buchneri比L. plantarum更有效.
科学领域:
- 动物和乳制品科学动物和乳制品科学
- 微生物学 微生物学
- 农业科学 农业科学
背景情况:
- 料生产对于保持料质量至关重要.
- 乳酸细菌 (LAB) 是改善料发酵的关键添加剂.
- 在了解特定的LAB接种剂的影响时,S. perfoliatum料将受益.
研究的目的:
- 为了评估Lactiplantibacillus plantarum和Lentilactobacillus buchneri对S. perfoliatum料的作用.
- 评估发酵质量,化学成分,消化能力和细菌群体动态.
- 为了确定S. perfoliatum料生产的最佳LAB添加剂.
主要方法:
- 用L. plantarum或L. buchneri接种剂 (5 × 10^6 cfu/g FW) 或没有 (对照) 进行化.
- 在60天内分析了发酵参数,化学成分 (CP,NH3-N,LA,AA),体外CP消化能力 (ivCPD) 和细菌群体结构.
- 进行了细菌群落的预测功能分析.
主要成果:
- 植物增加了乳酸 (LA) 和降低了pH. L. buchneri降低了氨 (NH3-N) 和增加了酸 (AA).
- 无论是L. plantarum还是L. buchneri都增加了原蛋白 (CP) 含量. L. buchneri在体外显著提高了CP消化能力 (IVCPD).
- 细菌群落从Weissella_A和Pantoea_A转移到Lactiplantibacillus和Lentilactobacillus. 这些细菌群落已经从Weissella_A和Pantoea_A转移到了Lactiplantibacillus和Lentilactobacillus. L. buchneri在45天后占主导地位,并在发酵后影响了细菌的继承.
结论:
- L. buchneri的注射显著改善了S. perfoliatum料的质量,特别是NH3-N的减少和IVCPD.
- 与L. plantarum相比,L. buchneri在料发酵上表现出更明显的积极作用.
- 在实际应用中,L. buchneri被推作为一种优质的添加剂,用于增强S. perfoliatum料发酵.

Microbial Fermentation
406
Fermentation is a crucial anaerobic metabolic process that enables microbes to derive energy from sugar without relying on oxygen or an electron transport chain. This process is fundamental to various biological and industrial applications and is classified based on the metabolic products generated.Role of Pyruvate in FermentationPyruvate and its derivatives serve as key electron acceptors in fermentative pathways. The oxidation of NADH to regenerate NAD+ is essential for the continuation of...
