Özet

Dalapon (2,2-DCP) is one of the herbicides that has been frequently used in Türkiye since the mid1950s and has a polluting effect in nature. The maximum concentration limit (MCL) for Dalapon in drinking water, determined worldwide, is 200 µg/L. The accepted concentration for Dalapon to be poured into water in Türkiye is 6000 mg/L. In studies conducted on the effects of Dalapon on aquatic organisms, it was observed that Dalapon at a concentration of 3800 mg/L had a toxic effect on Rasbora heteromorpha species fish when touched for 48 hours. According to research, Dalapon was detected in around 0.61 µg/L in drinking water, 0.01 µg/L in wastewater, and 0.23-0.28 µg/L in tap water. This research, it is aimed to provide simultaneous Dalapon biodegradation and electricity production by using the Psychrobacter sp. Taeburcu001 strain, which was recently isolated from Antarctica and can use Dalapon as a carbon source, with microbial fuel cells (MFC). Single-chamber MFCs were prepared and operated according to previous papers. Five experiment groups are carried out with single-chambered MFCs, and voltage graphs at different Dalapon concentrations (10 mM and 20 mM) are drawn accordingly using a computer-based data acquisition device. Experiment groups contain MFCs that include only Psychrobacter sp. Taeburcu001, only mixed culture taken from the local wastewater treatment plant, and Psychrobacter sp. Taeburcu001 with mixed culture, respectively. An open system and an abiotic system are also used as control groups. For the analysis, microbial ecology analysis is done for the evaluation of microbial communities that form on the anode, and biodegradation analysis is done via LC-MS device. Findings indicate that higher concentrations of Dalapon were causing lower voltage production on only mixed culture experiment groups. It is thought that the information obtained will be a pioneer for the investigation of other pollutants.
