Abstract: Ensiling is a method of preserving a moist crop. A moist crop can support the growth of a wide range of microorganisms, most of which will degrade the nutrient value to livestock. However, ensiling generally controls microbial activity by a combination of an anaerobic environment and a natural fermentation of sugars by lactic acid bacteria on the crop. This fermentation and the resulting low pH primarily suppress the growth of other anaerobic microorganisms. The fermentation can also inhibit yeasts, molds and … Show more

“…Different results can be expected, since each enzyme requires specific water activity, temperature, pH, enzyme and substrate concentration to achieve maximum benefit (Aehle, 2004). In the current experiment, the increase of acetic acid concentration is partially related to the linear increase of aerobic bacteria in silo, notably of acetic acid bacteria which may grow at low pH (Muck, 2010).…”

“…Yeasts are usually the first microorganisms to grow after oxygen exposure. Yeast development is based on lactic acid utilization in aerobic environment, increasing silage pH and allowing the growth of spoilage microorganisms (Muck, 2010).…”

“…The inoculants used in this study (P. pentosaceus and L. plantarum) are aimed at increasing the production of lactic acid, and as a consequence, reducing the production of ammonia N and DM losses during the fermentation process through more efficient metabolic pathways (McDonald et al, 1991;Muck, 2010). However, the application of the inoculant in cabbage silages treated with 200 and 300 g kg -1 of ground corn increased the production of ammonia N and gas losses.…”

“…Segundo Woolford (1990), a deterioração da silagem, quando exposta ao ar, é inevitável e pode resultar em perda substancial de matéria seca. Esses eventos ocorrem, principalmente, em silagens resultantes de fermentação desejável, cuja marca é a elevada concentração de lactato (MUCK, 2010), o que sugere a busca por novas cepas de micro-organismos que promovam aumento da estabilidade aeróbia das silagens. Nesse sentido, espécies e cepas do gênero Bacillus produzem substâncias com ação antimicrobiana, inclusive antibióticos, o que possibilita a utilização destas no controle biológico de fitopatógenos (LANNA FILHO et al, 2010 Baldes plásticos, com capacidade de 7L, foram utilizados como silos experimentais, nos quais havia 0,5kg de areia no fundo, separados da forragem por uma tela fina de plástico com malha, adequada para evitar o contato entre areia e silagem, para quantificação de efluentes.…”
