Geobacter sulfurreducens str. YM18

Geobacter sulfurreducens strain YM18 is a Gram-negative, rod-shaped bacterium that thrives under anaerobic conditions, with an optimal growth temperature of 30.0°C. This strain is part of a broader group of Geobacter species known for their ability to reduce metal ions and contribute to biogeochemical cycles, particularly in environments where organic matter is present. G. sulfurreducens YM18 is notable for its versatile habitat utilization, suggesting it can adapt to a variety of anaerobic environments. This adaptability may enable it to play significant roles in the degradation of organic compounds and in the reduction of metal oxides in various ecosystems, including sediments and subsurface environments. The metabolic pathways employed by this strain facilitate electron transfer processes that are crucial for energy acquisition in oxygen-limited settings. The ecological significance of G. sulfurreducens YM18 lies in its potential applications in bioremediation and bioenergy, particularly in the context of microbial fuel cells, where its ability to transfer electrons to electrodes could be harnessed for sustainable energy production. Furthermore, the strain's adaptation to multiple habitats underscores the importance of anaerobic microorganisms in maintaining ecosystem functions, particularly in conditions where oxygen is scarce.
