Influence of ions on growth and production of exopolysaccharides by Lactobacillus delbrueckii subsp. bulgaricus NCFB 2772.
Several lactic acid bacteria produce exopolysaccharides (EPS), either attached to the cell wall or excreted into the environment as slime material. EPS produced by Lactobacillus delbrueckii subsp. bulgaricus (Lb. bulgaricus) and Streptococcus thermophilus play an important role in improving the texture and stability of yogurt and preventing syneresis (Cerning, 1990; Nakajima et al. 1990). The a...
متن کاملThe nature of some growth stimulatory substances for Lactobacillus delbrueckii.
In addition to the usual amino acids and vitamins, Lactobacilus delbrekii strain 730 (ATCC 9649) has been shown to require pyridoxamine phosphate (McNutt and Snell, 1950), thymidine (Kitay, et al., 1950), and an unsaturated fatty acid (e. g., oleic acid) (Kitay and Snell, 1950) for growth. In addition to these absolute requirements for growth, partial acid hydrolyzates of casein further stimula...

متن کاملUtilization of molasses sugar for lactic acid production by Lactobacillus delbrueckii subsp. delbrueckii mutant Uc-3 in batch fermentation.
Efficient lactic acid production from cane sugar molasses by Lactobacillus delbrueckii mutant Uc-3 in batch fermentation process is demonstrated. Lactic acid fermentation using molasses was not significantly affected by yeast extract concentrations. The final lactic acid concentration increased with increases of molasses sugar concentrations up to 190 g/liter. The maximum lactic acid concentrat...
متن کاملDNA Probe for Lactobacillus delbrueckii.
From a genomic DNA library of Lactobacillus delbrueckii subsp. bulgaricus, a clone was isolated which complements a leucine auxotrophy of an Escherichia coli strain (GE891). Subsequent analysis of the clone indicated that it could serve as a specific DNA probe. Dot-blot hybridizations with over 40 different Lactobacillus strains showed that this clone specifically recognizes L. delbrueckii subs...
