Pick to: 【 objective 】 of three common microbes for regular physiological and biochemical reaction identification. 【 methods 】 through the hydrolysis of starch sugar fermentation test, test, methyl red test and v-general test of three common microbes under physiological and biochemical reaction determination. 【 results 】 the hydrolysis of starch test results is bacillus subtilis can produce amylase; Sugar fermentation tests prove escherichia coli and ordinary proteus and produces acid and gas and bacillus subtilis in a small amount of organic acid; Methyl red test prove escherichia coli and bacillus subtilis and ordinary proteus positive; V-general test results is bacillus subtilis and ordinary proteus reaction was positive. 【 conclusion 】 the hydrolysis of starch sugar fermentation test, test, methyl red test and v-general test can never tongfang face to identify common strains.
