In this study the effects of temperature, pH, and addition of some minerals were investigated in lactic acid fermentation using Enterococcusfaecalis RKY1. As a result, strain of RKY1 had retained biological activity at the wide range of temperature(34-46°C) and pH(6.0-9.0), and the optimum temperature and pH were 42°C and 7.0, respectively. When the effect of various phosphate sources added on lactic acid fermentation was studied, di-basic forms of phosphate(especially, ammonium phosphate and potassium phosphate) had more stimulating effect rather than monobasic phosphate sources. And there were no perceivable effect of manganese and magnecium salts addition on lactic acid fermentation.
