Investigation on L-rhamnose metabolism of <i>Loigolactobacillus coryniformis</i> subsp. <i>coryniformis</i> DSM 20001 and its propionate-containing fermentates.

ABSTRACT: Propionate is an important short-chain carboxylic acid (SCCA) that serves as an effective antimicrobial agent for food preservation. Previous research has highlighted that few Lactobacillaceae can synthesize propionate by metabolizing deoxyhexoses via the fermentation intermediate 1,2-propanediol (1,2-PD). In this study, we investigated propionate production by Loigolactobacillus coryniformis subsp. coryniformis DSM 20001 while utilizing L-rhamnose as the primary carbon source. We cultivated L. coryniformis in small-scale anaerobic bioreactors at 30°C and pH 6.5 for 72 h and monitored the expression of key genes associated with deoxyhexose metabolism using quantitative PCR. In addition, we assessed the contribution of individual SCCA to the antimicrobial activit
