Description | Shrihari, et al. (1993) observed the growth of free bacteria unattached to the sulfur surface in an artificial (membrane) culture system, but later studies on models of sulfur oxidation included the major role of adsorbed bacteria. Using natural culture conditions, we have observed sulfur oxidation by both free and adsorbed bacteria. A dominant oxidation role for free bacteria was suggested based on kinetic observations in both growing and non-growing cultures. The linear phase of sulfur oxidation was related to sulfur limitation in agreement with the Monod equation. The role of adsorbed bacteria may be to solubilize sulfur. |
