Effect of some of medium constituents on the levels of phosphotransacetylase in the extract of Lactobacillus fermenti 36 IFO No. 3071 was examined, using modified MaciasR's basal medium widely used in the microbiological assay of thiamine. Experimental demonstrated that D-xylose had a significant stimulatory effect on growth, but also had a results significant repressive effect on the phosphotransacetylase level of L.fermenti. It was also found that D-glucose had an effect of inducing the formation of phosphotransacetylase, and that this effect was completely inhibited by chloramphenicol. Pantothenate in the medium had no effect of inducing the enzyme. Other vitamins such as thiamine, biotin, and nicotinic acid, had some effect on both the growth and the enzyme level when they were compared with each other at lower levels of vitamins, whereas, bu no effect at a higher level. It was suggested that phosphotransacetylase of L.fermenti might be induced by D-glucose to perform hetero-lactic acid fermentation (as shown in Chart 2).
