PCT No. PCT/DK93/00116 Sec. 371 Date Jul. 2, 1993 Sec. 102(e) Date Jul. 2, 1993 PCT Filed Mar. 30, 1993 PCT Pub. No. WO93/20180 PCT Pub. Date Oct. 14, 1993A method of inducing malolactic fermentation in wine or fruit juice by the direct inoculation of a concentrate of a starter culture containing a selected malolactically active bacterial strain or strains having the accession no. DSM 7008, DSM 7009, DSM 7010, DSM 7011, DSM 7012, DSM 7013, DSM 7014 and DSM 7015. Further, the strains are characterized as having a survival rate of at least 80% when introduced into a wine having a pH of 3.2 or lower and containing at least 25 mg SO2 per L and at least 12 vol % ethanol. Also the strains are capable of starting malolactic fermentation when added directly to the wine or fruit juice at a concentration of less than 107 colony forming units per mL.
