Effect of temperature (5-25°C) on epiphytic lactic acid bacteria populations and fermentation of whole-plant corn silage

Abstract

This study demonstrated the impact of temperature gradient on the diversity and some important population shift of lactic acid bacteria communities during fermentation of corn silage.

Effects of Lactobacillus buchneri isolated from tropical maize silage on fermentation and aerobic stability of maize and sugarcane silages

“…In our study, populations of yeasts and moulds in the fresh forage were greater than the previous studies with maize silage (Assis et al., ; Filya, ; Zhou et al., ). This difference in population could be attributed to factors such as maize hybrid, maturity and environmental conditions.…”

“…Several studies have investigated the diversity of epiphytic LAB during the maize ensiling process. In general, L. plantarum and P. pentosaceus were the predominant LAB species in the beginning of fermentation, whereas L. buchneri and L. brevis were widely detected few days after ensiling (Brusetti et al, 2006;Lin, Bolsen, Brent, & Fung, 1992;Parvin, Wang, Li, & Nishino, 2010;Stevenson, Muck, Shinners, & Weimer, 2006;Zhou et al, 2016). It is generally recognized that to produce a high-quality silage, the fermentation should start with homofermentative LAB species.…”

“…Although the whole‐plant maize is the most widely used crop as silage in the world, studies about microbial diversity of this silage in tropical climate are rare (Zhou, Drouin, & Lafrenière, ). Maize has adequate characteristics for good fermentation in a silo, but severe losses can occur during the feed‐out phase (Santos et al., ).…”

Effects of inoculants and environmental temperature on fermentation quality and bacterial diversity of alfalfa silage

“…; Zhou et al . ). In tropic and sub‐tropic regions, the longer period of hot weather is considered a main factor that results in poor‐quality silage.…”

Effects of storage temperature and combined microbial inoculants on fermentation end products and microbial populations of Italian ryegrass (Lolium multiflorumLam.) silage

“…Such silages are often found to have high pH value, low rate of pH decline (Ali et al 2015) and low acid production (Kung 2010). Zhou et al (2016) reported that low temperature could reduce fermentation efficiency by lowering the growth rate and enzymatic activity of micro-organisms. Even, the commercial lactic acid bacteria (LAB) inoculants might be inhibited and are thus not effective at low temperatures (Kim and Uchida 1990;Weinberg and Muck 1996).…”
