The Significance ofPropionibacteriumSpecies andMicrococcus lactilyticusto the Ensiling Process

摘要

The fermentation of lactic acid by twoPropionibacteriumspp. and byMicrococcus lactilyticuswas examined in simulated silage. Fermentation occurred in silages which achieved a low pH (<4·0) but this resulted only in a small rise in pH and a secondary clostridial fermentation did not occur. Lactic acid‐fermenting organisms resemblingPropionibacteriumspp. were isolated from authentic silages but not from fresh gra
