Growth kinetics of Pseudomonas aeruginosa RS1 on fluorene and dibenzothiophene, concomitant degradation kinetics and uptake mechanism.

ABSTRACT: The current study illustrates the growth kinetics of an efficient PAH and heterocyclic PAH degrading bacterial strain, Pseudomonas aeruginosa RS1 on fluorene (FLU) and dibenzothiophene (DBT) over the concentration 25-500 mg L^-1 and their concomitant degradation kinetics. The specific growth rate (µ) was found to lie within the range of 0.32-0.57 day^-1 for FLU and 0.24-0.45 day^-1 for DBT. The specific substrate utilization rate (q) of FLU and DBT over the log growth phase was between 0.01 and 0.14 mg FLU mg VSS^-1 day^-1 for FLU and between 0.01 and 0.18 mg DBT mg VSS^-1 day^-1 for DBT, respectively. The µ and q values varied within a narrow range for both FLU and DBT and they did not
