Abstract

Dimethylamine (DMA) possesses an obnoxious odor which has resulted in public concern during the past several decades. A rare bacterial species proficient to degrade DMA, designated IR-26, was isolated from Indian Oil Corporation Limited (IOCL) and identified as Agromyces and Ochrobactrum sp., which has presented a rapid degradation when compared to other bacterial species which were capable to degrade DMA. The removal efficiency of 100% has been calculated in different concentration of DMA. The kinetic study reveals the maximum reduction rate of DMA was 0.11 per hour and the maximum growth rate of biomass was 0.013 per hour respectively. The saturation constant of DMA was around 1.96 mg/L which shows a high affinity of DMA. The importance of these analyses is offered and conversed in this paper.
