Production of Leuconostoc oenos Biomass under pH Control †

摘要: Leuconostoc oenos was grown on apple juice-based media. The effect of pH control metabolism and biomass production studied. Without control, L. acidified the juice media to approximately 3.6. More than 75% malic acid used under these conditions, but less half carbohydrates assimilated. Under yields increased by 60%; most used, high levels unfermented remained. addition tomato juice, vitamins, nucleotides, Mn+, did not permit further increases in cell counts; however, induce acidification. Growth without favored a more homofermentative metabolism. Biomass higher filter-sterilized compared with that autoclaved
