Biomass from activated sludge reactors operating at different dilution rates (0.09, 0,16, and 0.24/h) was used to examine the effect of sludge age on Ni2+ removal characteristics, running batch adsorption tests. The kinetic studies have revealed that sludge grown at all dilution rates, exhibits both active and passive uptake of Ni2+. Although percentages of active and passive uptake changed with the age of activated sludge biomass, passive uptake was the dominant mechanism in Ni2+ sorption. The data obtained were interpreted in the form of adsorption isotherms. At all dilution rates, linear adsorption isotherms were obtained., indicating the presence of equilibrium between biomass and the free nickel species.

Anaerobic treatment of olive mill wastes in batch reactors Bayramoğlu, Tuba Hande; DEMİRER, GÖKSEL NİYAZİ (Elsevier BV, 2000-01-01) Anaerobic treatment of olive oil mill wastes, namely black water and prina, was investigated in batch reactors. Biochemical methane potential (BMP) tests were conducted to determine the anaerobic biodegradability of black water and/or prina. With these BMP tests the biodegradability of olive mill wastes (OMWs) at different initial chemical oxygen demand (COD) concentrations and corresponding methane gas productions were investigated. Furthermore, a screening study was performed to determine the most importa...
Kinetics of riboflavin production by Brewers' yeasts Tamer, I.M.; Özilgen , Mustafa; Ungan, Suat (Elsevier BV, 1988-12) The kinetics of riboflavin production by Saccharomyces cerevisiae and Saccharomyces carlsbergensis in synthetic media and wort were studied. The results indicated that riboflavin was produced by growing cells only. Riboflavin production rate was proportional to growth rate of the yeasts in the exponential phase. Riboflavin was depleted in the stationary phase. The depletion rate was expressed with a first-order kinetic expression in yeast concentration. The kinetics of substrate utilization and ethanol prod...
Oxygen transfer effects in serine alkaline protease fermentation by Bacillus licheniformis: Use of citric acid as the carbon source Çalık, Pınar (Elsevier BV, 1998-12-01) The effects of oxygen transfer on serine alkaline protease (SAP) production by Bacillus licheniformis on a defined medium with C-c = 9.0 kg m(-3) citric acid as sole carbon source were investigated in 3.5 dm(3) batch bioreactor systems. The concentrations of the product (SAP) and by-products, i.e., neutral protease, amylase, amino acids, and organic acids were determined in addition to SAP activities. Ar Q(o)/V = 1 vvm airflow rate, the effect of agitation rate on DO concentration, pH, product, and by-produ...
Substrate interactions during the biodegradation of benzene, toluene and phenol mixtures Abu Hamed, T; Bayraktar, E; Mehmetoglu, T; Mehmetoglu, U (Elsevier BV, 2003-09-30) Benzene, toluene and phenol were degraded completely at high initial concentrations by Pseudomonas putida F I ATCC 700007. Two hundred and fifty milligram per litre benzene, 225 mg/l toluene and 200 mg/l phenol were degraded individually in 19, 14 and 3 5 h, respectively. The biodegradation times increased on increasing the substrate concentration. The maximum biodegradation rates were 149 mg benzene/g dry cell h for 60 mg/l benzene, 44 mg toluene/g dry cell h for 110 mg/l toluene and 102 mg phenol/g dry ce...
KINETICS OF SPONTANEOUS WINE PRODUCTION OZILGEN, M; CELIK, M; BOZOGLU, F (Elsevier BV, 1991-03-01) Substrate consumption, ethanol production, microbial growth, and temperature increase in a fermentation vessel are metabolically interrelated biological phenomena. In spontaneous wine fermentations, mixed cultures of various microbial species are involved in the fermentation process. Due to the continuously changing species contributing to the microbial population, these metabolically interrelated parameters are treated separately in the enology literature. In the present study, mathematical models are pres...
