(A) Degradation of chrysene by MS-benzoate grown cells of PB-1 and PB-2, incubated for 21 days. Data represent the mean and standard deviation of triplicate determination of initial and final concentration respectively. The error bars (Standard Deviation) were due to differential response of cells in triplicate tubes. (B) Chrysene dependent growth and cell numbers distribution of strains PB-1 and PB-2, in chrysene incubated for 21 days. Data represent the mean of replicates tubes for initial time (0) cell density represented as (1) and final time (21 days) represented as (4) respectively. The x-axis value range was chosen as such to allow for even spread of the growth curve. The error bars (Standard Deviation) were due to differential response of cells in triplicate tubes.
