Biokinetics of Aeromonas hydrophila utilizing glucose in an anaerobic biosystem were evaluated. A sequential approach with a fitting specific growth rates to the initial glucose concentrations followed by a solving differential equations numerically using the 4th order Runge-Kutta method was used to estimate the parameter values.1 During the batch culure of
Aeromonas hydrophila a complete mineralization of glucose, 5000 mg L-1, occurred in approximately 34 hours of incubation. Ethanol, acetate, succinate, and formate were the metabolic products. The hypothetical maximum growth rate, μm, half saturation coefficients, Ks, microbial yield, Y, cell mass decay rate, kd, and substrate inhibition coefficient, Ksi, were
evaluated as being 0.25 ± 0.03 hr-1, 118 ± 31 mg glucose L-1, 0.12 μg DNA mg glucose-1, 0.01 hr-1, and 3108 ± 1152 mg glucose L-1, respectively. Using the estimated parameters, the theoretical performance of the continuous operation with an influent glucose concentration of 5000
mg L-1 was also illustrated. The expected glucose utilizing efficiencies were greater than 95% at 7 hours or longer HRTs. Aeromonas hydrophila was expected to be washed out at 6.7 hours of HRT.
