Achromatium oxaliferum shows negative chemotaxis to oxygen, sulfide, and nitrate, switching from undirected to directed movement against each chemical gradient for over 1 hour.
- Why it matters: Migration at the oxic–anoxic interface is linked to daily oxygen changes, but the cues and behavioral mechanism driving Achromatium vertical positioning were unclear.
- What they did: The study used chemotaxis assays and time-lapse microphotography to track rolling and gliding, then combined lab experiments with bioinformatic analysis of its genetic repertoire.
- The result: The observed directed movement toward low concentrations, together with predicted type IV pili and many chemo- and photoreceptors, suggests negative chemo- and phototaxis helps confine Achromatium between opposing oxygen and sulfide gradients.
