“…In addition, Lactiplantibacillus , one of the most commonly used inoculants, can rapidly produce lactic acid and lower the pH in forage fermentation, and Lentilactobacillus can enhance the aerobic stability of various forages ( 16 ). In the ensiling process, particularly in the initial phase of ensiling, the metabolisms of plant cells and microbes contribute to gas production (carbon dioxide [CO 2 ] greater than 60%), resulting in greenhouse gas emissions and losses of DM and energy from the ensiled material ( 17 ). Chen et al ( 18 ) found that Lactobacillus plantarum can decrease CO 2 production by the control microbial community during silage fermentation.…”

Oat natural silage is rich in Enterobacteriaceae , increasing gas production and fermentation loss. Lactic acid bacteria interact synergistically to form a dominant community during ensiling. Pediococci grow vigorously in the early stage of fermentation and create an anaerobic environment. Lactobacilli inhibit the harmful microorganisms and result in cleaner fermentation of oat silage.

“…Chen et al also detected Acinetobacter in the king grass silage [ 45 ]. Klebsiella , a facultative anaerobic bacterium, has been found in many silages [ 46 , 47 , 48 ]. It is a detrimental microorganism to silage, and its growth is usually inhibited in a low pH environment [ 49 ].…”

This study was to investigate the effects of cellulase and xylanase on fermentation characteristics, nutrient composition and the bacterial community of the mixed silage of king grass and rice straw. Lab-scale bag silage was produced and seven groups were studied: blank control (CK); added 1%, 2% cellulase (CE1, CE2); added 1%, 2% xylanase (XY1, XY2); and added 0.5% cellulase +0.5% xylanase, 1% cellulase +1% xylanase (CX1, CX2). The results showed that the application of additives in six treated groups exerted a positive effect on lactic acid (LA) content and their pH values decreased significantly (p < 0.05). The addition of cellulase and xylanase decreased (p < 0.05) the content of neutral detergent fiber (NDF) and acid detergent fiber (ADF) significantly and increased (p < 0.01) the crude protein (CP) and water-soluble carbohydrate (WSC) content. Filter paper enzyme activity (FPA) declined and xylanase activity (XA) intensified (p < 0.05) as ensiling was prolonged, where most of the enzymatic treatments (especially XY2, CX2) resulted in increased enzyme activities. Moreover, the addition of cellulase and xylanase reduced the abundance of harmful bacteria such as Acinetobacter and Klebsiella and increased the abundance of lactic acid bacteria such as Lacticaseseibacillus, Lactiplantibacillus. In conclusion, the addition of cellulase and xylanase would improve fermentation quality and nutrient preservation via altering the bacterial community, with 1% cellulase or complex enzyme best.

“…The increase in the number of Proteobacteria and decrease in Firmicutes after 3 days of ensiling is an uncommon phenomenon, which has been mainly associated with the proliferation of Enterobacter and Klebsiella (Wang et al, 2021;Zhang et al, 2022). This phenomenon could be explained by the early stage ensiling conditions, characterized by a higher pH (> 5.0) and a micro-oxygen environment (oxygen remaining after sealing), which favoured the growth of Proteobacteria over Firmicutes, leading to a brief period of Proteobacteria dominance.…”

Effects of Pyroligneous Acid on Diversity and Dynamics of Antibiotic Resistance Genes in Alfalfa Silage

Abstract: Antibiotic resistance genes (ARGs) are considered environmental pollutants posing a potential human health risk. Silage is an important and traditional feed, mainly for ruminants.
