Abstract
A novel nicotine-degrading bacterium, strain Y22, was isolated and identified as Rhodococcus sp. Y22 based on its 16S rDNA sequence and morphological and biochemical features. The isolate could utilize nicotine as the sole source of carbon and nitrogen. Nicotine (1.0 g/L) was degraded by Rhodococcus sp. Y22 within 52 h at 28 °C and pH 7.0. Preparation of resting cells from nicotine-induced cultures was found to rapidly and efficiently degrade nicotine from solutions as well as from tobacco leaves. Therefore, Rhodococcus sp. Y22 has the potential to degrade nicotine during tobacco leave processing.
