From 143 sources of collected samples, the distribution of nicotinophiles were investigated and the biological characteristics as well as the rate of nicotine degradation were determined for the selected 34 strains which could grow successfully in the nicotine media, and one of the most effective strains was chosen and identified at the species level. Nicotinophils were distributed abundantly in the soils rich with organic materials, tobacco seed and root. The selected 34 strains were classified into 7 genus and identified with 4 strains of Arthrobacter, 11 strains of non-pigmented Pseudomonas, 2 strains of pigmented Pseudomonas, 6 strains of Alkaligenes, 5 strains Chromobacter 2 strains of Listeria and 4 strains of Achromobacter. Pseeudomonas and Alkaligenes were better than other genus in the rate of nicotine degradation and tobacco seed and root were also good sources for the isolation of effective nicotinophiles. Amnog 34 strains, strain NCT 27 which exhibited 97.l% of nicotine degradation rate was the best one for nicotine degradation and was indentified with Pseudomonas putida.
