“…(3) are namely the culture maximum specific growth rate, half saturation constant and inhibition constant, respectively, due to substrate j in the system (Ziagova et al 2009 It can be seen that quinoline exhibits stronger inhibition on glucose degradation at all concentrations in the present study. But for glucose, the parameter value was negative, its effect on quinoline utilization was stimulative.…”

“…Hess et al (1993) who studied the biodegradation of 2,4-dinitrophenol by a mixed culture found that its degradation was enhanced by the individual addition of acetate, yeast extract and glucose. Ziagova et al (2009) also reported that the degradation rates of 2,4-dinitrophenol and 4-cl-m-cresol was enhanced by the presence of glucose. In these conditions, the toxicity and inhibition of recalcitrant/toxic substrates can be attenuated and degradation rates can be significantly enhanced.…”

An indigenous mixed culture of microorganisms, isolated from a full-scale coal gasification wastewater treatment plant, was used in degrading quinoline in presence of glucose as an alternative carbon source. The results showed that biodegradation kinetics of both quinoline and glucose could be described by first-order reaction kinetics model. It was also found that the biodegradation rate of quinoline was accelerated by the presence of glucose, while glucose degradation was inhibited by the presence of quinoline. Both the biomass yield coefficient and specific growth rate were increased with the increasing of the glucose concentrations in the dual substrates system. A sum kinetics model was used to describe the relative effects of the two substrates on their individual uptakes. The interaction parameter values indicated that quinoline exhibits stronger inhibition on glucose degradation. But for glucose, its effect on quinoline utilization was stimulative. Furthermore, the stimulation was positively correlated with the concentration of glucose in the system.

“…SA-6 in the presence of biphenyl supplementation, although, the strains were unable to utilize tetrachlorobiphenyls as growth substrate. Ziagova et al (2009) have reported a comparison of the ability of Staphylococcus xylosus to degrade 2,4-dichlorophenol and 4-Cl-m-cresol in separate cultures. In this study, bacterial adaptation and the continuous presence of glucose, as a conventional carbon source, were found to stimulate the degrading efficiency of S. xylosus.…”

Sustainable development requires the development and promotion of environmental management and a constant search for green technologies to treat a wide range of aquatic and terrestrial habitats contaminated by increasing anthropogenic activities. Bioremediation is an increasingly popular alternative to conventional methods for treating waste compounds and media with the possibility to degrade contaminants using natural microbial activity mediated by different consortia of microbial strains. Many studies about bioremediation have been reported and the scientific literature has revealed the progressive emergence of various bioremediation techniques. In this review, we discuss the various in situ and ex situ bioremediation techniques and elaborate on the anaerobic digestion technology, phytoremediation, hyperaccumulation, composting and biosorption for their effectiveness in the biotreatment, stabilization and eventually overall remediation of contaminated strata and environments. The review ends with a note on the recent advances genetic engineering and nanotechnology have had in improving bioremediation. Case studies have also been extensively revisited to support the discussions on biosorption of heavy metals, gene probes used in molecular diagnostics, bioremediation studies of contaminants in vadose soils, bioremediation of oil contaminated soils, bioremediation of contaminants from mining sites, air sparging, slurry phase bioremediation, phytoremediation studies for pollutants and heavy metal hyperaccumulators, and vermicomposting.

“…The improved PAM degradation showed that low concentrations of glucose can be used as co-metabolism substrate with PAM by both of the strains. This is because conventional carbon sources at low concentrations stimulate microbial growth, which lead to higher levels of enzymes available for the degradation of toxic compounds [23]. However, if too much conventional carbon sources are present, the microorganisms will use the conventional carbon sources in priority instead of toxic compounds to satisfy their growth and metabolism, consequently lead to the decrease of the biodegradation.…”
