Sorry, no etymologies found.
In Egypt the principal microorganisms reported in kishk are the heterofermentative Lb. brevis and the homofermentative Lb. cased and Lb. plantarum.
The essential microorganisms in the pulque fermentation are Lb. plantarum, a heterofermentative Leuconostoc, Sac. cerevisiae, and Zymomonas mobilis.
The result is an excessively sour-tasting product that lacks the flavor otherwise produced by the heterofermentative Leuconostoc and Lactobacillus spp.
Carbon dioxide produced by heterofermentative lactobacilli also has a preservative effect in foods, resulting, among others, from its flushing action and leading to anaerobiosis if the substrate is properly protected.
The heterofermentative Leuconostoc plays the essential role of producing dextrans, which contribute a characteristic viscosity to pulque and also increase the acidity of the agave juice very rapidly, inhibiting growth of other less desirable bacteria.
