“…The experimental data fitted better the Haldane kinetic model than the Monod equation ( Figure 5). The above values were in the range of literature values (Sokol 1987;Bandyopadhyay et al 1998;Bales & Antosova 1999;Monteiro et al 2000;Loh & Chua 2002).…”

A new indigenous soil bacterium Pseudomonas sp. growing on phenol and on a mixture of phenol, toluene, o-cresol, naphthalene and 1,2,3-trimethylbenzene (1,2,3-TMB) was isolated and characterized. Phylogenetic analysis suggested its classification to Pseudomonadaceae family and showed 99.8% DNA sequence identity to Pseudomonas pseudoalcaligenes species. The isolate was psychrotroph, with growth temperatures ranging from ca. 0 to 40 degrees C. The GC-MS structural analysis of metabolic products of phenol degradation by this microorganism indicated a possible ortho cleavage pathway for high concentrations (over 200 mg L(-1)) of phenol. Biodegradation rates by this species were found to be three times more effective than those previously reported by other Pseudomonas strains. The effect of temperature on phenol degradation was studied in batch cultures at temperatures ranging from 10 to 40 degrees C and different initial phenol concentrations (up to 500 mg L(-1)). Above 300 mg L(-1) of initial phenol concentration no considerable depletion was recorded at both 10 and 40 degrees C. Maximum degradation rates for phenol were recorded at 30 degrees C. The biodegradation rate of phenol was studied also in the presence of additional carbon sources (o-cresol, toluene, naphthalene, 1,2,3-TMB) at the optimum growth temperature and was found significantly lower by a factor of eight in respect to the strong competitive inhibition between the substrates and the more available sources of carbon and energy. The Haldane equation mu = mum S/(Ks + S + S2/K1) was found to best fit the experimental data at the optimum temperature of 30 degrees C than the Monod equation with kinetic constants mum = 0.27 h(-1), KS = 56.70 mg L(-1), KI = 249.08 mg L(-1).

“…It was also able to use a wide diversity of carbon energy substrates and this together with their ability to compete effectively with other bacteria, is undoubtedly responsible for their dominance [22]. Pseudomonas putida EKII, Pseudomonas cepacia G4, Pseudomonas putida Q5, Pseudomonas putida MTCC were investigated as phenol degrader as well as all of them were non pathogenic [16,[23][24][25][26].…”

Phenol widely used in industries, are of growing concern owing to their toxicity and wide distribution in industrial wastes. The aims of the study were to characterize some of the locally isolated bacteria and to develop suitable methods for the degradation of phenol using them. Locally isolated AP11, AP9, AP6 and AP7 were identified as Pseudomonas putida using the classical methods. Pseudomonas putida AP11 and AP9 were able to remove 600 ppm phenol completely, but Pseudomonas putida AP6 and AP7 were able to remove 400 ppm phenol completely. The maximum degradation rates for freely suspended culture of Pseudomonas putida AP11, AP9, AP6, AP7 were 10.83, 10.42, 8.33, and 8.33 (ppm/h) respectively. The isolates AP11, AP9, AP6 and AP7 can be used to wastewater containing phenol in effluent treatment systems.
