Green bean juice was fermented with 10 species (14 strains) of heterofermentative and two homofermentative lactic acid bacteria to select organisms which might be used to carry out a complete fermentation. Lactobacillus cellobiosus was the only organism to remove all fermentable sugars from bean juice with or without 2.5% NaCI. Nine other cultures used from 75–95% of the sugars. Lactobacillus cellobiosus also produced the lowest final pH among the 14 strains. A complete analysis of the major fermentation substrates and products was done for each of the organisms. Fermentation balance calculations showed a range from 74–132% carbon recovery. These bacteria showed considerable variation in the ability to degrade malic acid and to form mannitol and acetic acid.
