The species of microorganisms dominating a laboratory-scale once-through activated sludge unit treating simulated wastewater with different influent strengths (650 and 1300 mgl(-1) COD) and containing 5 to 10 mgl(-1) Ni(II) and 1 to 50 mgl(-1) Cr(VI) were identified by standard biochemical tests. Within this framework, combinations of metals and influent COD concentrations were tried. Organisms, namely Proteus rettgeri, Acinetobacter sp., Flavobacterium lutescens, Bacillus cereus var. albolactis, Klebsiella sp., Arthrobacter simplex, and Pseudomonas mendocina, were identified at different stages of the experiments.

Combined effects of Ni(II) and Cr(VI) on activated sludge Dilek, Filiz Bengü; Yetiş, Ülkü (1998-02-01) The combined effects of Ni(II) and Cr(VI) on activated sludge kinetics were studied in this paper. The metals were added to a synthetic medium with a chemical oxygen demand (GOD) of 1300 mgl(-1) to give various combinations of Ni(II) and Cr(VI). Activated sludge performance, in terms of COD removal, was not adversely affected in an acclimatized culture by the metal combinations, compared with the single metals. The combination effects of Ni!II) and Cr(VI)on biokinetic constants, i.e. the maximum specific gr...
Microbial detoxification of groundnut meal naturally contaminated with aflatoxin using rhodococcus erythropolis Doğan, Önay Burak; Çekmecelioğlu, Deniz; Bozoğlu, Faruk; Department of Food Engineering (2015) Aflatoxins are highly mutagenic toxins with carcinogenic effects produced as secondary metabolites by fungal species Aspergillus flavus and Aspergillus parasiticus under certain conditions. Chronic or acute consumption of aflatoxins found in food and feed products possesses great health risks. It is particularly an important problem in animal feed from food waste and by-products. Therefore there is growing need to eliminate aflatoxins from contaminated products. In this study, first the optimum growth condi...
Biophysical and microbiological study of high hydrostatic pressure inactivation of Bovine Viral Diarrheavirus type 1 on serum CEYLAN, ÇAĞATAY; Severcan, Feride; ÖZKUL, AYKUT; Severcan, Mete; Bozoglu, Faruk; Taheri, Nusret (Elsevier BV, 2012-01-27) The effect of high hydrostatic pressure application on fetal bovine serum components and the model microorganism (Bovine Viral Diarrheavirus type 1 NADL strain) was studied at 132 and 220 MPa pressure for 5 min at 25 degrees C. Protein secondary structures were found to be unaffected by an artificial neural network application on the amide I region for both untreated and HHP treated samples. FTIR spectroscopy study of both the HHP-treated and control samples revealed changes in the intensity of some bands i...
A study of the relative dominance of selected anaerobic sulfate-reducing bacteria in a continuous bioreactor by fluorescence in situ hybridization İçgen, Bülent; Harrıson, S.T.L. (Springer Science and Business Media LLC, 2007-01-01) The diversity and the community structure of sulfate-reducing bacteria (SRB) in an anaerobic continuous bioreactor used for treatment of a sulfate-containing wastewater were investigated by fluorescence in situ hybridization. Hybridization to the 16S rRNA probe EUB338 for the domain Bacteria was performed, followed by a nonsense probe NON338 as a control for nonspecific staining. Sulfate-reducing consortia were identified by using five nominally genus-specific probes (SRB129 for Desulfobacter, SRB221 for De...
Microbial Community Degradation of Widely Used Quaternary Ammonium Disinfectants Oh, Seungdae; Kurt, Zöhre; Tsementzi, Despina; Weigand, Michael R.; Kim, Minjae; Hatt, Janet K.; Tandukar, Madan; Pavlostathis, Spyros G.; Spain, Jim C.; Konstantinidis, Konstantinos T. (American Society for Microbiology, 2014-10-01) Benzalkonium chlorides (BACs) are disinfectants widely used in a variety of clinical and environmental settings to prevent microbial infections, and they are frequently detected in nontarget environments, such as aquatic and engineered biological systems, even at toxic levels. Therefore, microbial degradation of BACs has important ramifications for alleviating disinfectant toxicity in nontarget environments as well as compromising disinfectant efficacy in target environments. However, how natural microbial ...
