W. Eckert, MICROBIALLY-RELATED REDOX CHANGES IN A SUBTROPICAL LAKE .2. SIMULATION OF METALIMNETIC CONDITIONS IN A CHEMOSTAT, Biogeochemistry, 21(1), 1993, pp. 21-38
The individual influence of sulfate reducing and brown phototrophic su
lfur bacteria from Lake Kinneret on the metalimnetic redox conditions
was investigated by simulating the hydrochemical and microbiological c
onditions in a specially designed chemostat. The results show a strong
correlation between measured redox values and the prevailing hydrogen
sulfide concentration leading to a linear relationship. Changes in th
is relationship allowed differentiation between the on-going microbial
processes, sulfate reduction and sulfide oxidation. The comparison of
in vitro and in situ redox values shows that the results of the simul
ation experiments agree with the data previously measured in the metal
imnion of Lake Kinneret.
