C Correct answer
Explanation

Yes, it is correct. 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. Corynebacterium glutamicum has been used since several decades for the large-scale production of amino acids, esp. l-glutamate and L-lysine. Glycerol is a major by-product of ethanol fermentation by Saccharomyces cerevisiae.
