In the present study we reported the feasibility of extracellular biopolymer (PF-9) produced by Pseudomonas fluorescence C-9 as an alternative biosorbent to remove Pb(II) metallic ions from environmental and industrial wastewater.The ability of PF-9 to remove the metallic ions was investigated by using batch biosorption procedure. The effects such as, pH, biosorbent dosage, sorbate concentrations...
The Pb(II) biosorption characteristics of Pseudomonas fluorescens PFC02 biomass was examined as a function of initial pH, contact time and initial metal ion concentration. FTIR spectra showed that the principal functional sites taking part in the sorption process included carboxyl , hydroxyl groups and -CH3 stretching groups, the mechanism analysis showed that the chemical chelating was the main adsorption...
In this study, the optimal conditions of production of bioflocculant by the culture of Pseudomonas alcaligenes PS-25 were examined, using brewery wastewater to replace glucose as carbon source and energy source in the culture medium. Results showed that the COD concentration in brewery wastewater favorable for the production of the bioflocculant was 5000 mg??L-1, and an optimal culture condition of...
In order to increase the output of bioflocculant, improve efficiency and stability of flocculation and reduce the cultivating cost, Pseudomonas fluorescensC-2 strain was cultured in brewery wastewater culture medium where brewery wastewater replaced glucose as carbon source and energy source to produce bioflocculant, then the bioflocculant obtained was applied to treat middle phase wastewater in paper...
