This study examined the effect of B-group vitamins on the growth of commercially available probiotic cultures at two different pH environments. Results showed that the highest growth occurred with the vitamin B complex at pH7. Culture growth at pH7 with vitamin B6 and vitamin B12 was lower than with vitamin B complex. All differences were statistically significant at alpha=0.05. As expected growth decreased at pH3 and was comparably lower for all B vitamins than the growth observed at pH7. The highest growth at pH3 was observed with B complex added to the medium, and the difference was significant. For treatments with B6 and B12 growth appeared as low as in the vitamin-free control, and means for all three at pH3 were not significantly different. This study confirmed that vitamin B complex (all eight from the B group) stimulated tested probiotic culture at pH7. The study also confirmed that the vitamin B complex provided better conditions for culture survival at pH3 than Vitamin B6 and B12.
