Enzymes are biodegradable and renewable resources that utilize water as the reaction solvent. Reactions catalyzed by enzymes are among the most effective, selective, and 'green' processes available today. The advantages of using biocatalysts include their high degree of regio- and stereo-specificity, versatility, and high reaction rates under mild reaction conditions. Enzyme catalyzed enantioselective C-C bond formation reactions are rather important aspects of synthetic organic chemistry. Thiamine pyrophosphate (TPP) dependent enzymes, especially, have an important role in the stereo-selective formation of C - C bonds. This review covers the recent advances in enzyme catalyzed asymmetric C-C bond formation using the most pronounced thiamine pyrophosphate dependent enzymes: acetohydroxyacid synthase, benzaldehyde lyase, benzoylformate decarboxylase, pyruvate decarboxylase, and phenylpyruvate decarboxylase. These enzymes are all capable of acyloin-type condensation reactions in water under mild conditions, in turn leading to chiral a-hydroxy ketones, which are versatile building blocks for the pharmaceutical and chemical industries.

Screening and In Situ Monitoring of Potential Petroleum Hydrocarbon Degraders in Contaminated Surface Water İçgen, Bülent (Wiley, 2017-01-01) Incomplete combustion of fossil fuels and other anthropogenic activities result in contamination of surface water by petroleum hydrocarbons. These pollutants can have severe effects on aquatic life and human health. In petroleum bioremediation, oil degrading microorganisms are utilized to remove petroleum hydrocarbons from polluted water. However, monitoring and identifying microorganisms capable of degrading petroleum hydrocarbons is very challenging. In the current study, bacteria isolated from a river al...
Aerobic Bacterial Degraders With Their Relative Pathways for Efficient Removal of Individual BTEX Compounds Yavas, Alper; İçgen, Bülent (Wiley, 2018-11-01) Benzene, toluene, ethylbenzene, and xylene (BTEX) compounds are of great environmental concern due to their toxicity and carcinogenicity. Bacterial removal of BTEX has proven to be highly efficient, cost-effective, and nondisruptive, provided that, efficient bacterial degraders are available. The objective of this study, therefore, is to discover aerobic bacterial degraders with their relative pathways that could be employed for the efficient removal of individual BTEX compounds. A total of 22 petroleum hyd...
Anaerobic-Fed and Sequencing-Batch Treatment of Sugar-Beet Processing Wastes: A Comparative Study Alkaya, Emrah; Demirer, Göksel Niyazi (Wiley, 2011-03-01) The aim of this study was to compare a batch-fed continuously mixed anaerobic reactor (FCMR) with an anaerobic sequencing batch reactor (ASBR), in terms of waste stabilization and methane production treating sugar-beet processing wastewater and beet-pulp simultaneously. A reactor was operated as FCMR, which then was operated as an ASBR by changing operational conditions after the steady-state was reached. Although the hydraulic retention time value of the ASBR configuration was lower (8 days) than that of t...
Modeling biogeochemical dynamics in porous media: Practical considerations of pore scale variability, reaction networks, and microbial population dynamics in a sandy aquifer King, E. L.; Tuncay, Kağan; Ortoleva, P.; Meile, C. (Elsevier BV, 2010-03-01) Prediction of the fate and environmental impacts of groundwater contaminants requires the identification of relevant biogeochemical processes and necessitates the macroscopic representation of microbial activity occurring at the microscale. Using a well-studied sandy aquifer environment, we evaluate the importance of pore distribution on organic matter respiration in a porous medium environment by performing spatially explicit simulations of microbial metabolism at the sub-millimeter scale. Model results us...
Anaerobic co-digestion of sewage sludge and primary clarifier skimmings for increased biogas production Alanya, S.; Yılmazel Tokel, Yasemin Dilşad; Park, C.; Willis, J. L.; Keaney, J.; Kohl, P. M.; Hunt, J. A.; Duran, M. (IWA Publishing, 2013-01-01) The objective of the study was to identify the impact of co-digesting clarifier skimmings on the overall methane generation from the treatment plant and additional energy value of the increased methane production. Biogas production from co-digesting clarifier skimmings and sewage sludge in pilot-scale fed-batch mesophilic anaerobic digesters has been evaluated. The digester was fed with increasing quantities of clarifier skimmings loads: 1.5, 2.6, 3.5 and 7.0 g COD equivalent/(L.d) (COD: chemical oxygen dem...
