Kinetics of microbial growth on pentachlorophenol.
Batch and fed-batch experiments were conducted to examine the kinetics of pentachlorophenol utilization by an enrichment culture of pentachlorophenol-degrading bacteria. The Haldane modification of the Monod equation was found to describe the relationship between the specific growth rate and substrate concentration. Analysis of the kinetic parameters indicated that the maximum specific growth r...
متن کاملDegradation kinetics of pentachlorophenol by Phanerochaete chrysosporium.
The extracellular enzymes and cell mass from the pregrown Phanerochaete chrysosporium cultures were used for the degradation of PCP. The use of both extracellular enzymes and cell mass resulted in extensive mineralization of PCP, while the action of only the crude extracellular enzymes led to the formation of a degradation intermediate (TCHD). A kinetic model, which describes the relationship a...
متن کاملSlow Sorption Kinetics of Pentachlorophenol on Soil: Concentration Effects
We investigated the sorption kinetics of pentachlorophenol (PCP) on soil at a pH of 4.1 using batch techniques. A multiple spiking methodology was employed to circumvent the solubility limitation of PCP. The ratio of sorbed PCP to solution-phase PCP (S/C) after 2-4 days of equilibration was concentration dependent. It decreased from 90 to 60 L/kg with a 4-fold increase in the total PCP concentr...

متن کاملMicrobial growth and substrate utilization kinetics
Microbial growth on and utilization of environmental contaminants as substrates have been studied by many researchers. Most times, substrate utilization results in removal of chemical contaminant, increase in microbial biomass and subsequent biodegradation of the contaminant. These are all aimed at detoxification of the environmental pollutants. Several microbial growth and biodegradation kinet...
