Abstract The US Environmental Protection Agency listed phenolic compounds as priority pollutants, and their occurrence in water systems poses serious health risks to humans and other living species. The culture conditions are extremely crucial for microbial growth, enzymatic and cellular metabolic activities. Thus, the effects of different culture parameters like pH, temperature (°C), and agitation speed (RPM) on the indigenous Rhodococcus pyridinivorans strain PDB9T NS-1 were modeled using response surface methodology (RSM) and central composite design (CCD). The results showed that the main effect of pH and interaction between pH and agitation speed had a significant to a moderately significant effect on phenol degradation by the indigenous R. pyridinivorans strain PDB9T NS-1. Almost complete phenol degradation was obtained at an optimal setting of pH 7.5, 187 rpm, and 34 °C in 18 h. Growth and phenol degradation kinetics of the actinomycetes was examined in a batch shake flask under the optimized conditions. The growth of Rhodococcus species at varying initial levels of the phenol followed a Pamukoglu and Kargi substrate inhibition model with half-saturation constant (Ks ) of 54.21 mg/l, maximum specific growth rate (µ max) of 0.169 (1/h), substrate inhibition constant (Ksi ) of 243.26 mg/l. The results obtained from the optimization of culture conditions and growth kinetics by the indigenous R. Pyridinivorans strain PDB9T NS-1 suggest the potential of the system in the treatment of phenolic wastewater.

The quality of life in water bodies depends on their physico-chemical properties and biodiversity. These physico-chemical properties are being disturbed by continuous addition of industrial, municipal and agricultural wastes which make them unfit for different organisms. This study describes the physico-chemical factors in soil and water of all sampled wetlands and the relationship among them in wetland ecosystem. All these analysis were done by using analytical techniques as described by standard methods for examination of water and wastewater. Physico-chemical parameters of water and soil also interlinked and correlated among each other. Sometimes these parameters work as a cycle to maintain the equilibrium in the ecosystem. Higher level of research work is needed to control the source of pollution to wetlands. By controlling the physico-chemical parameters of habitat, the diversity, density and richness of various wetland dependent species can be controlled in wetland ecosystem.
