Effects of anaerobic condition on the stress resistance and the loquat wine's malolactic fermentation of Lactobacillus plantarum R23

The growth characteristics of Lactobacillus plantarum R23 in the loquat wine and the effects of the anaerobic condition and inoculation levels on the growth and malolactic fermentation of Lactobacillus plantarum R23 were studied.The results showed that the biomass of Lactobacillus plantarum R23 in the loquat wine was downtrend;the survival rate and malolactic fermentation of Lactobacillus plantarum R23 in the loquat wine were improved on the anaerobic condition;the attenuated rate of the biomass of Lactobacillus plantarum R23 and the acid reduction rate were increased with the inoculation amount adding.The suitable inoculation amount for the loquat wine's bio-deacidification was 1×108cfu·mL-1,L-malate was completely transformed into L-Lactate at 25±1℃ on anaerobic condition for 2 days.
