Abstract

The relationship between the number of bacteria,Escherichia coli and nitrite was studied.Total ten bacteria strains were isolated from fermented radish,wherein nine nitrrate reducing bacteria were screened by the determination of conversion ability of nitrate to nitrite.Among them,the strains E5 and E6 had the highest nitrate reducing activity.Furthermore,nitrate reductase activity of these two strains and the influence of pH on such activity were analysed.According to the biochemical and molecular identification,E5 was identified as Enterobacter cloacae and E6 was Klebsiella oxytoca.

Key words： fermented radish; Enterobacter cloacae; Klebsiella oxytoca; nitrate reductase
