    Optimization of biodegradation of anthracene by corynebacterium sp and pseudomonas putida
    (U.P., 2015-05) Azeez, Taofik Oladimeji; Owabor, Chiedu Ngozi; Nwakaudu, Madueke Stanley; Usondu, Nnamuzie Francis
    The carcinogenic potential of industrial effluent discharged of anthracene on the ambient environment withcontamination to soils and aquifers is not only environmental concern but difficulty in implementation of biodegradation of anthracene due to inability to optimizing the process parameters. The optimization of process parameters for biodegradation of anthracene with the activity of Corynebacterium sp and Pseudomonas putida using response surface methodology was aimed to be investigated. A 23 of full factorial central composite design was employed for developed quadratic polynomial model to achieve optimal performance of the process. Statistically,high correlation coefficient (R2 ) for quadratic polynomial model for biodegradation of anthracene by activity of Corynebacterium sp 0.9659 (p<0.05)and Pseudomonas putida 0.9939 (p<0.05)were obtained. The optimum conditions for anthracene degradation by Corynebacterium sp were 69.99g/L, 83.20hours and 3.4735vvm with about 98.48 percent of anthracene degraded while Pseudomonas putida were 69.989g/L, 83.58hours and 3.5vvm with 89.51percent of anthracene degraded.
