“…Therefore, applying citric acid might be one of the factors that contribute to the higher abundance of P. fermentans and the less aerobically stable in CA group. A higher relative abundance of W. anomalus was detected in all L. plantarum a214 treated silages, which was in accordance with the report by Jiang et al (2020a) that inoculation of L. plantarum could accelerate the growth of W. anomalus .…”

“…It is noteworthy that the dominated Pichia species of silages is different in silages, and P. kudriavzevii and P. fermentans were the predominant fungi in CK and CA silages, respectively. All of them were often detected in aerobic spoilage silages ( Li and Nishino, 2011 ; Jiang et al, 2020a ). According to Wang et al (2018) , P. kudriavzevii showed high tolerance to lactic and acetic acids.…”

“…According to Wang et al (2018) , P. kudriavzevii showed high tolerance to lactic and acetic acids. The high relative abundance of P. kudriavzevii made aerobic deterioration easier ( Jiang et al, 2020a ). Thus, inhibition of P. kudriavzevii might be an effective strategy for alleviating aerobic corruption in some instance.…”

The aim of this study was to investigate the influence of Perilla frutescens, alone or in combination with Lactobacillus plantarum a214 or citric acid, on forage oat silage quality, bacterial and fungal microbiological profile during ensiling and aerobic exposure. With the exception of Perilla frutescens, all additives could improve silage quality of forage oat based on lower ammonia-nitrogen content and higher residual of water soluble carbohydrates during anaerobic fermentation compared to control silage, especially in Perilla frutescens combined with citric acid (CAPF). Lactobacillus was the dominant bacteria in all silages, while CAPF group increased the relative abundance of Lactobacillus lindneri and Lactobacillus brevis compared to control silage. The application of Perilla frutescens suppressed the relative abundance of yeasts such as Pichia fermentans and Wickerhamomyces anomalus in response to aerobic exposure, especially in CAPF treatment, leading to high acetic acids and lower dry matter loss, as well as good aerobic stability. Therefore, Perilla frutescens, alone or in combination with citric acid, has potential to improve aerobic stability of forage oat silage by shifting bacterial and fungal community composition, and can be used as new additive to prepare high-quality silage for animal production.

“…PS is a well-known additive in the conservation of a variety of feeds because of its antifungal properties [12]. Yeast is the key factor in the aerobic deterioration of silage, and the silage more easily deteriorated when the number of yeasts reached 10 5 cfu g −1 (FM) [41]. Many yeast species could oxidatively metabolize lactic acid via the tricarboxylic acid cycle, which decreased the acidity of TMR silage and allowed for the growth of spoilage bacteria [42].…”

This study aimed to evaluate the effect of the application of an inoculant and a preservative on the fermentation quality, in vitro digestibility, and aerobic stability of alfalfa silage-based fermented total mixed ration (TMR). The TMR was ensiled with (1) no additives (control), (2) Lactobacillus plantarum (LP), or (3) potassium sorbate (PS). The V-scores of all silages were higher than 80 points during the 30 days of ensiling. The addition of LP and PS had no effects on the in vitro parameters, such as in vitro digestibility and in vitro gas production (p > 0.05). LP-treated silage showed similar fermentation quality and comparable aerobic stability to the control (110 h). The LP only decreased the ammonia nitrogen (NH3-N) content (p < 0.05) during ensiling. The PS significantly increased the pH of TMR silages (p < 0.05). Meanwhile, the addition of PS improved the aerobic stability (>162 h) of TMR silage, indicated by the higher water-soluble carbohydrate content and lower NH3-N content in comparison with those in the control after aerobic exposure (p < 0.05). The improvement in fermentation quality is extremely small in terms of applying LP in TMR silage based on a large percentage of other silage ingredients. The PS is effective in conserving unpacked TMR silage and showed the potential to reduce the risk of ruminal acidosis in livestock.

“…However, at the final stage of the ensiling, a considerable proportion of Issatchenkia (Issatchenkia orientalis, I. orientalis) presented in Linoculated groups and it accounted for about 60% of the total population when stored at 15°C. I. orientalis also referred to as Pichia kudriavzevii (P. kudriavzevii), which was often recognized in aerobic spoilage silages (Jiang et al, 2020;Li & Nishino, 2011). According to the report of Li et al (2021), P. kudriavzevii is tolerant to many different environmental stresses especially acidic and salty stress .…”

This study investigates the effectiveness of an exopolysaccharide (EPS)‐producing strain (Lactiplantibacillus plantarum L75) alone or in combination with Saccharomyces cerevisiae on the fermentation characteristics, antioxidant capacities and microbial community successions of oat silage stored at various temperatures. A rapid decrease in pH and lactic acid accumulation was observed in silages treated with L. plantarum and S. cerevisiae (LS) as early as 3 days of ensiling (p < 0.05). Over the ensiling period of 7–60 days, L. plantarum (L)‐inoculated groups showed the lowest pH, lowest ammonia nitrogen and the highest amount of lactic acid regardless of the storage temperatures. When the oat silage was stored at 15°C, LS‐inoculated group exhibited a higher superoxide dismutase (SOD) activity than control and L‐inoculated group. Furthermore, the proportion of Lactiplantibacillus in the combined inoculation group increased by 65.42% compared to the L‐inoculated group (33.26%). Fungal community data revealed abundant Penicillium carneum in the control and L‐inoculated groups stored at 15°C. Conclusively, these results showed that combined inoculation of L. plantarum L75 and S. cerevisiae improved the fermentation quality of oat silage at 15°C, thus proposing a technique for enhancing the fermentation quality of silage in regions with low temperatures during harvest season.
