Description
Summary:Enterococcus faecalis and Enterococcus faecium strains were used to perform lactic acid fermentation in hydrolyzed sago starch (HSS). The objective was to compare and to determine which strain produce higher concentration of lactic acid (LA). The fermentation conditions for both bacteria were the same and fixed at 37°C, pH of 6.5 and agitated at 200 rpm. It was found that these conditions were the optimum for both strains to grow and to produce LA. It was demonstrated that E. faecalis produce higher LA concentration when compared with E. faecium in the same operating conditions. Therefore, E. faecalis has more attractiveness for a possible scaling up for industrial application.
