Abstract:
〈 p style="text-align: justify;" 〉 〈 em 〉 Leuconostoc oenos 〈 /em 〉 strains: m, L 〈 sub 〉 2 〈 /sub 〉 ST, X 〈 sub 〉 2 〈 /sub 〉 L, have been isolated from different Argentinian red wines. Amino acids, vitamins and base requirements were determined in a synthetic medium containing L-malic acid, citric acid or both organic acids. The organisms differed in their requirements. The growth of the four 〈 em 〉 L. oenos 〈 /em 〉 strains studied was greater in the synthetic medium with L-malic acid plus citric acid. In this medium, 〈 em 〉 L. oenos 〈 /em 〉 m, L 〈 sub 〉 2 〈 /sub 〉 , and ST eliminated their amino acid requirements, however X 〈 sub 〉 2 〈 /sub 〉 L in the same medium increased these requirements. In respect of the vitamin and base requirements, 〈 em 〉 L. oenos 〈 /em 〉 m and L 〈 sub 〉 2 〈 /sub 〉 showed no significant difference by the addition of L-malic acid, citric acid or both organic acids to the synthetic medium. 〈 em 〉 L. oenos 〈 /em 〉 ST needed L-malic acid plus citric acid to avoid these requirements, while the X 〈 sub 〉 2 〈 /sub 〉 L strain increased its requirements with both organic acids. 〈 /p 〉
