Microorganisms involved:
The most predominant organisms for the gundruk fermentation are Pediococcus and Lactobacillus species. The fermentation is initiated by L. cellobiosus and L. plantarum, and other homolactics make a vigorous growth from the third day onwards. Pediococcus pentosaceus increases in number on the fifth day and thereafter declines (Karki et al., 1983) During fermentation, the pH drops slowly to a final value of 4.0 and the amount of acid (as lactic) increases to about 1% on the sixth day (Karki et al., 1983).
