Malolactic fermentation in wine is carried out by

  • A.Yeasts of the genus Saccharomyces only
  • B.Acetic acid bacteria such as Acetobacter aceti
  • C.Filamentous moulds growing on the wine surface
  • D.Lactic acid bacteria, chiefly Oenococcus oeni

Answer: D

It is a bacterial step, distinct from the yeast-driven alcoholic fermentation, and Oenococcus oeni predominates because it tolerates the low pH and the alcohol. Calling it a fermentation is slightly misleading, since it is a decarboxylation rather than a sugar fermentation.
