W. Eckert et Hg. Truper, MICROBIALLY-RELATED REDOX CHANGES IN A SUBTROPICAL LAKE .1. IN-SITU MONITORING OF THE ANNUAL REDOX CYCLE, Biogeochemistry, 21(1), 1993, pp. 1-19
Using a recently developed in situ multiprobe the redox development in
the water column of warm-monomictic Lake Kinneret was investigated du
ring three annual cycles. During the time when sulfide release into th
e meta- and hypolimnion is initiated, our measurements show a linear r
elationship, close to the thermodynamic function, between the platinum
electrode potential and the amount of sulfide produced by the sulfate
reducing bacteria. A change of this relationship during summer strati
fication coincides with the bloom of the phototrophic sulfur bacterium
Chlorobium phaeobacteroides.
