Biological Treatment of Micropollutants

Municipal wastewater is the main source of micropollutants which are present in the household products (detergents, cosmetics and paints) and natural excretion of humans (drugs and metabolites, synthetic hormones) (Bruchet et al., 2002; Bicchi et al., 2009). After their use, pharmaceuticals are excreted intact and/or as metabolites with feces and urine; thus are introduced directly into wastewater (Lo¨ffler et al., 2005). New sanitation concepts where wastewater streams are separated and treated according to their characteristics is thus an important source control strategy to avoid input of pharmaceuticals to the wastewaters and in turn to the environment.


Occurrence and Reduction of Emerging Contaminants in Sludge
Sanin, Faika Dilek (null; 2019-06-13)
Emerging contaminants consist of a wide range of anthropogenic as well as natural substances which include pharmaceuticals,personal care products, steroid hormones, industrial chemicals, pesticides and many other emerging compounds. Since theirconcentrations vary from a few ng/L to several μg/L, they may also be called as micropollutants. There has been a growingawareness and concern about these chemicals for the last few decades since many of these are known to have toxic, carcinogenic orendocrine disrupti...
Biodegradation of the Allelopathic Chemical Pterostilbene by a Sphingobium sp. Strain from the Peanut Rhizosphere
Yu, Ri-Qing; Kurt, Zöhre; He, Fei; Spain, Jim C. (American Society for Microbiology, 2019-03-01)
Many plants produce allelopathic chemicals, such as stilbenes, to inhibit pathogenic fungi. The degradation of allelopathic compounds by bacteria associated with the plants would limit their effectiveness, but little is known about the extent of biodegradation or the bacteria involved. Screening of tissues and rhizosphere of peanut (Arachis hypogaea) plants revealed substantial enrichment of bacteria able to grow on resveratrol and pterostilbene, the most common stilbenes produced by the plants. Investigati...
Bioactive thiazole and benzothiazole derivatives
Rouf, Abdul; Tanyeli, Cihangir (2015-06-05)
The heterocycles are the versatile compounds existing in almost all natural products and synthetic organic compounds, usually associated with one or the other biological activity. Among the heterocycles the thiazoles and benzothiazoles occupy a prominent position. They possess a broad range of biological activities and are found in many potent biologically active molecules and drugs such as vitamin thiamine, sulfathiazol (antimicrobial drug), ritonavir (antiretroviral drug), abafungin (antifungal drug) and ...
Asymmetric organocatalytic sulfa-michael reactions of thioglycolate with isatin derived nitroalkenes
Sağesen, Selin; Tanyeli, Cihangir; Department of Chemistry (2018)
Organosulfur compounds are present in many natural products and drugs. Sulfa-Michael reaction is the prominent method to synthesize these molecules. The novel bifuctional organocatalysts developed in our research group enable sulfa-Michael reaction to ocur asymmetrically. In this thesis, biologically active isatin derived nitroalkenes were chosen as Sulfa-Michael acceptors. Addition of methyl thioglycolate to isatin derived nitroalkenes in the presence of the bifunctional organocatalysts was studied under d...
Radiation Treatment of Wastewater for Reuse with Particular Focus on Wastewaters Containing Organic Pollutants
Ergun, E; Kantoğlu, Ömer; İnce, Mahir; Bayramoğlu, Tuba Hande; Dilek, Filiz Bengü (International Atomic Energy Agency, 2018-01-01)
In this period of the research, aerobic and anaerobic digestion, characterization of alkaloids present and radiolysis products formed after irradiation, under different conditions of ambient and additives, optimization of dose to achieve desired end characteristics for discharge of waste water were aimed. In this regard, unirradiated and irradiated wastewaters were subjected to aerobic and anaerobic digestions. Substrate removal efficiencies of unirradiated and i...
