修改后的句子： My research experience in magnetic biochar during my undergraduate showed me the preciseness and pleasure of scientific research, which piqued my initial interest. As a result, I chose to pursue a master's degree after graduating from college. During my master's program, I focused on biological wastewater treatment and one of my research objectives was to investigate the metabolism of microbes in wastewater treatment. In the process of consulting relevant literature on microbial metabolism, I discovered that some studies utilized microbial electrochemistry, specifically microbial extracellular electron transfer, to explore the intricate details of microbial metabolism. This newfound knowledge fascinated me and sparked my interest in conducting future research in the field of microbial electrochemistry. As a result, I made the decision to pursue a PhD degree in this direction.
