FIG. 2.

(A) Time courses of the DMS concentrations in the incoming gas (■) and outgoing gas (□) in the chemostat. The chemostat was inoculated (10%) with a 10-fold-diluted sediment slurry (see text) that had been preincubated with DMS. The slurry was prepared from a eutrophic pond sediment (Campus of Dekkerswald Institute). (B) Time courses (start-up phase) of the amount of DMS consumed (▴) and the amounts of MT (●) and methane (⧫) produced by a chemostat inoculated with a pure culture of strain DMS1^T.
