Optimization of culture condition for growth and phenol degradation byAlcaligenes faecalisJF339228 using Taguchi Methodology

Characteristics of phenol degradation in saline conditions of a halophilic strain JS3 isolated from industrial activated sludge

“…The application of fungi to degrade aromatic pollutants in wastewater has been reported (Santos and Linard, 2004;D'Annibale et al, 2004;Margesin et al, 2005), most of which are effective even in high concentration of phenol. Majority of previous studies focus on the phenol biological treatment by non-halophilic bacteria or fungi which are hard to metabolize in high salt conditions (Jiang et al, 2005;Wei et al, 2008;Paisio et al, 2013;Kumar et al, 2013). More attention should be paid to salt-tolerant phenol-degrading microorganisms because large quantities of hypersaline phenol-containing effluents were drained into surface water.…”

Bioattenuation of phenol and cyanide involving immobilised spent tea activated carbon with Alcaligenes faecalis JF339228: Critical assessment of the degraded intermediates

“…The favourable pH conditions for the growth of A . faecalis JF339228 was maintained at pH 7 as revealed by Kumar et al for phenol degradation using A . faecalis JF339228.…”

“…Bio‐remediative microbial cells enzymatically utilises organic wastes as a source of carbon and energy with chemical conversion into nontoxic secondary metabolites. Alcaligenes faecalis JF339228 is an isolated bacteria from steel plant wastewater capable of phenol degradation, but few studies have been explored for degradation of phenol and cyanide . Owing to the difficulties associated with dealing high pollutant concentrations by the biomass, immobilisation was adopted as a cost‐effective process in terms of cell recycle cell recovery and enhanced detoxification efficacy.…”

“…Alcaligenes faecalis JF339228 is an isolated bacteria from steel plant wastewater capable of phenol degradation, but few studies have been explored for degradation of phenol and cyanide. 21 Owing to the difficulties associated with dealing high pollutant concentrations by the biomass, immobilisation was adopted as a cost-effective process in terms of cell recycle cell recovery and enhanced detoxification efficacy. Development of biolayer on the adsorbent, continuous diffusion of pollutants into biosorbent surface, and transfer of solutes into the bulk solution phase help in the maintenance of dynamic equilibrium for binary solute system.…”

Evaluation of mass transfer effect and response surface optimization for abatement of phenol and cyanide using immobilized carbon alginate beads in a fixed bio‐column reactor

“…The mixed microbial cultures were retained at pH 7.0 ± 0.2 and temperature 30°C ± 5°C in a sterile medium. The nutrient medium contained beef extract (1.5 g/L), yeast extract (1.5 g/L), sodium chloride (5 g/L), and peptic digest of animal tissue (5 g/L) as reported by Mandal et al and Kumar et al The acclimatization of the bacterial strains to the simulated wastewater containing phenol and cyanide was performed by maintaining the concentration in 10:1 ratio as observed in the real industrial wastewater. The suspension of bacterial cells was performed in minimum salt media (ammonium sulfate (NH 4 ) 2 SO 4 ), dipotassium hydrogen phosphate (K 2 HPO 4 ), potassium dihydrogen phosphate (KH 2 PO 4 ), magnesium chloride (MgCl 2 ·7H 2 O), calcium chloride (CaCl 2 ·2H 2 O), and ferrous sulfate (FeSO 4 ·5H 2 O).…”
