“…They found that addition of sodium glutamate or glucose caused that bacteria grew faster and accumulated much more biomass than bacteria growing in medium containing phenol or 4-chlorophenol as the sole carbon source. The change of phenol biodegradation rate in the presence of glucose as a carbon source was also observed by Wang et al (1996). Studying the kinetics of utilization of phenol and glucose separately, and their mixtures by Pseudomonas putida ATCC 17514 they found that bacteria used glucose and phenol simultaneously but with lower specific rates.…”

“…In presented study, the similar effect was observed when glucose and catechol were present in the medium. Wang et al (1996) suggested that reduction of the specific substrate utilization rates indicates that the two substances are involved in a cross-inhibitory pattern, which is classified as uncompetitive. The effect of glucose on degradation rate of mixture of catechol (220 mg l -1 ) and phenol (188 mg l -1 ) by Pseudomonas sp.…”

“…Glucose, sodium glutamate and yeast extracts are common conventional carbon sources that have been widely used in biodegradation and biotransformation researches (Wang et al, 1996;Loh, 1999, 2001). For example, the rate of extent of pentachlorophenol degradation by bacteria significantly increased by addition of glucose and peptone (Yu and Ward, 1994).…”

Fatty acid composition in Pseudomonas sp. CF600 during degradation of catechol and phenol individually and their mixture was investigated. Moreover, the influence of glucose as an additional, easily degradable carbon source on fatty acid profiling in bacteria grown on these aromatic substrates was studied. Both catechol and phenol treatments caused in bacterial cells crucial changes in the distribution of tested groups of fatty acids. The major changes included the increase of fatty acid saturation, decrease in the percentage of cyclopropane fatty acid 17:0 cy and the appearance of branched and hydroxy fatty acids. Under catechol, phenol and their mixture exposure saturated/unsaturated ratio showed the value 6.5, 5.68 and 6.38 whereas in control cells this ratio reached the value 3.05. As a response to aromatic compounds bacteria formed fatty acids that were not detected in control cells growing on glucose. It has been demonstrated that the supplementation of cultured media containing single aromatic substrates or/and their mixture with glucose resulted in changes in degradation rates of catechol and phenol. It seemed that glucose influenced some metabolic pathways responsible for the assimilation of aromatic compounds. The incubation of cells in the presence of aromatic compounds and glucose rapidly led to alterations of whole-cell derived fatty acid composition. The most important changes were associated with saturation level of fatty acids and cyclopropane fatty acid contents.

“…Once the kinetics of cell growth on substrate is known, the use of substitutable and rate-controlling resource by a functional population of constant relative cell composition can be described if maintenance requirements are negligible [25]. The changes of phenol levels in cell medium (S cm ) with time in membrane contactors can be obtained considering the unsteady-state (dynamic) mass balances and grow kinetics of suspended cells:…”
