dc.description.abstract | The microbial degradation of vinyl acetate (VA) by Pseudomonas fluorescens PCM 2123 strain was
studied in both batch and continuous modes. The purpose of the experiments was to determine the kinetic model
of the cell growth and biodegradation rate of vinyl acetate (VA), which was the sole carbon and energy source for
tested microorganisms. The experiments, carried out in a batch reactor for several initial concentrations of growth
substrate in the liquid phase ranging from 18.6 to 373 gsubstrate·m–3 (gs·m–3) made it possible to choose the kinetic
model and to estimate its constants. The Haldane inhibitory model with the values of constants: μm = 0.1202 h–1,
KS = 17.195 gs·m–3, Ki = 166.88 gs·m–3 predicted the experimental data with the best accuracy. To set the
parameters of maintenance metabolism it was necessary to carry out a series of continuous cultures at different
dilution rates (0.05 to 0.072 h–1) and concentrations of VA in the liquid supplied to the chemostat ranging from
30.9 to 123.6 gs·m–3. The obtained data-base enabled to determine the coefficient for maintenance metabolism
(me = 0.0251 gsubstrate·gcell dry weight
–1·h–1 (gs·gcdw
–1·h–1)) as well as the maximal and observed values of yield
coefficients, Yxs
M = 0.463 gcdw·gs
–1 and (Yxs)obs = 0.411 gcdw·gs
–1, respectively. The developed kinetics was verified
by comparison of the computed and obtained in batch experiments profiles of changes in biomass and growth
substrate concentrations. | pl_PL |
