Formation of deoxyadenosine from adenosine by the washed cell suspension of Lactobacillus Leichmannii was first studied, and the best condition for the preparation of the compound was tested. The strain was previously cultured in a liquid medium for 16 hours. The cells thus prepared were collected, and to the washed cell-suspension were incubated the reaction mixture containing 1.1×10^<-2>M of adenosine in phosphate buffer (pH 6.4) at 37℃ without shaking. Thus, it was confirmed that adenosine may be convertible to the corresponding deoxyribonucleoside, deoxyadenosine.
