Explanation

Correct answer. Gluconobacter species are used for oxidation of D-sorbitol into L-sorbose in the commercial production of vitamin C (ascorbic acid). Various strains of Aspergillus niger are used in the industrial preparation of citric acid. Streptococcus thermophilus is used in making reduced-fat cheese with similar characteristics to regular full-fat cheese. Glycerol is a major byproduct of ethanol fermentation by Saccharomyces cerevisiae.
