Screening for rhodanese producing Bacterium in freshly pressed Cassava effluents of a Cassava processing industry channeled to Odo-Oba Stream in Ogbomoso-Nigeria

Abstract

Rhodanese is a key enzyme that plays an important role in cyanide detoxification. The enzyme was extracted, purified and physico-chemically characterised from Bacillus licheniformis which demonstrated the highest efficacy compared to the seven isolates of bacteria of the cassava processing industry effluent morpholologically and biochemically characterised. Statistical analysis was performed using one-way ANOVA and values were considered significant at p0.05). Therefore, B. licheniformis have the potentials of reducing cyanide pollution thereby enhancing effective management of cassava mill effluent before eventual discharge into the environment and this may be developed into a more effective tool for bioremediation.
