An inverstigation of the cultural characteristics of a soil bacterium that resemble the strain of Arthrobacter rufescens Akiba, Ueyama, Seki, et Fukimbara which is capable of growing on iso-propyl alcohol, was carried out.The optimum initial pH for microbial growth was 7.5-8.0. In general, when alcohols or glycols were used as the sole source of carbon, this strain required yeast extract. But, using a low concentration of these substrates, this strain did not require yeast extract. When isopropyl alcohol was used as a source of carbon, in this experiment, the maximum specific growth rate (μ_<max>(hr^<-1>)) and microbial yield were ca. 0.107 and 0.53,respectively. The essential amino acids content of dry cell matter almost satisfied as food protein. Elementary analysis of these cells showed nearly mean value of ones of other bacteria.
