Triticale stillage is a by-product of the bioethanol fermentation. It is used as the
addition to feed and needs the protection from spoiling and pathogens. Lactic acid
bacteria can be used for it, and triticale stillage is then used as a medium for their
growth and the lactic acid production. The aim of this work was to see if there is a
possibility for scale up of the lactic acid fermentation process (by increasing 10 times
medium volume), when an inoculum is Lactobacillus fermentum PL-1. Titrable acidity
and pH were measured during the lactic acid fermentation. Utilization of carbohydrates
and the concentrations of D- and L- lactic acid were determined by enzymatic kits.
Viability of the lactic acid bacteria cell was done by pour a plate method. There was no
difference in pH value during the process (medium volume changed from 25 to 250
mL), while titrable acidity was significantly lower. The L-lactic acid yield was also
smaller, but not significantly. Utilization of carbo...hydrates was complete in both cases,
and viability was better in the samples with the usual experimental design. Given
results indicate that the volume of the fermentation medium can be increased on a pilot
level, for example.
