![]() important discoveries regarding cell organization that have emerged from such studies. pombe particularly suited to EM and summarize the. It has also proved to be a suitable model organism for looking at cell architecture and ultrastructure using electron microscopy (EM). The fission yeast Schizosaccharomyces pombe has become a prominent model in molecular biology, both in yeast genetics and to investigate the molecular mechanism of the cell cycle. Additional laboratory and future in-field studies are warranted to improve the prediction of pathogen removal and AMR changes in tile drainage water, as well as to support the development of an effective design for microbial contaminant removal from waters passing through denitrifying bioreactors. A statistically significant and consistent increase in phenotypic AMR concentrations was also found within woodchip bioreactors after assessing the sensitivity of recovered isolates to five different antibiotics. Applying different microbial communities had significant effects on culturable microbial concentrations, as columns receiving more microbes with a greater diversity had a greater increase in culturable microbial concentrations. However, the results also illustrated that WBs have the potential to increase phenotypic antibiotic-resistant microbes in the subsurface drainage waters. coli concentrations within SDSs under different flow conditions, which expands the potential benefits of WBs. The results of this work demonstrated the potential for denitrifying bioreactors to reduce E. ![]() Steady and wet-dry flow conditions were examined. Four synthetic waters were spiked with different combinations of microbes isolated from the influent of a field-scale bioreactor and pumped through the columns during the experiment. A column study was conducted to simulate an existing, field denitrifying woodchip bioreactor. Therefore, the main objective of this study was to measure how bioreactors influence microbial concentrations and AMR concentrations in tile drainage water with different flow conditions and microbial communities. Although they are effective in removing nitrate, little is known regarding the potential impact on microbes and antimicrobial resistance (AMR) in subsurface drainage waters. ![]() Woodchip bioreactors (WBs) are a promising technology capable of decreasing nitrate concentration in subsurface (tile) drainage system (SDS) effluent. ![]()
