“…Degradation was inhibited both at low as well as high temperatures. These results substantiate with previous studies carried out by Cordova-Rosa et al (Cordova-Rosa et al 2009), on phenol degradation by soil Pseudomonad. Similar results have been reported on the Pseudomonas pictorum at 30 ºC (Annadurai et al 2007).…”

-In the present study, a pure culture of bacterium (Pseudomonas sp. Strain NBM11) was isolated from the soil sample from a site contaminated with medical wastes and wastewater. The isolated strain can degrade up to 1000 mg/L of phenol completely. It was observed that temperature, pH and initial concentration of phenol play key roles in determining the rate of phenol degradation. The isolated strain exhibited the maximal degradation of the substrate within a range of pH 6.8 to 7.2 and an incubation temperature between 30 ºC and 32 ºC. It was found that by increasing the concentration of phenol, the lag phase gets extended due to the inhibitory nature of phenol. The kinetic parameters such as µmax (maximum specific growth rate), Ks (half-saturation coefficient) and Ki (substrate inhibition constant) were estimated as 0.184 1/h, 7.79 mg/L and 319.24 mg/L, respectively, by fitting the growth kinetics data to the Haldane model of substrate inhibition. The bacterial strain was immobilized in alginate beads and its phenol degradation efficiency was observed to increase many fold. The immobilized cells were found to be used efficiently for seven cycles consecutively without any decrease in their efficiency.

“…Phenols and related compounds, which are high on the list of priority contaminants [1], may interfere with the ecosystem equilibrium and, consequently, may affect biogeochemical pathways of organic matter and nutrient recycling [2]. When phenol, a hydrophobic compound, is released into soil, its mobility becomes more restricted than in an aqueous environment due to its adsorption onto solid surfaces [2,3].…”

“…These resins are also used extensively as bonding agents in manufacturing wood products such as plywood and MDF generated by the activities of petrochemical, coal conversion, pesticide, paint, solvent, pharmaceutical, wood processing (playwood and MDF), and pulp and paper industries. They are also widely used as construction materials for automobiles and appliances, epoxy resins [4] and adhesives, and polyamide for various applications [5,6].…”

“…Most of the phenol removal studies in the literature are focused on bacterial biodegradation [1][2][3][4][5][6][7][8][9][10][11][12] and there is limited information on the phenol metabolization by the yeasts. Furthermore, little is known about the biodegradability of phenol by yeasts at colder temperatures [13,14] which is more significant for in-situ applications, compared to mesophilic temperatures [15].…”

Biotoxicity and low temperature are among the challenges of biodegradation as well as microbial transport in in-situ bioremediation applications. This study investigates the effect of low temperature, high and low concentrations of phenol, on biodegradability and the surface properties of Rhodotorula glutinis which may be instrumental to develop control mechanisms in engineering applications. Results showed that Rhodotorula glutinis is able to grow at low phenol (< 0.5 g/L) and glucose (1.0 g/L) concentrations. Microbial growth rates of Rhodotorula glutinis is the highest at 25°C for phenol fed reactors. Temperature and type of carbon source affected the total amount of extracellular polymeric substances (EPS) and the relative amounts of EPS constituents. Phenol fed Rhodotorula glutinis, at 4°C, were found to be hydrophobic whereas Rhodotorula glutinis showed less hydrophobic characteristics at 25°C, regardless of the carbon source. Surface hydrophobicity of Rhodotorula glutinis is related to the distribution of carbohydrate and proteins in the EPS.
