Dissimilatory reduction of inorganic sulfur by facultatively anaerobic marine bacteria.
THREE STRAINS, SELECTED FROM A LARGE NUMBER OF NEWLY ISOLATED, FACULTATIVELY ANAEROBIC MARINE BACTERIA, REDUCED INORGANIC SULFUR COMPOUNDS OTHER THAN SULFATE ANAEROBICALLY IN DEFINED CULTURE MEDIA IN THE FOLLOWING DIFFERENT PATTERNS: (i) sulfite and thiosulfate were reduced to sulfide, and tetrathionate was reduced to thiosulfate; (ii) tetrathionate was reduced to thiosulfate only; or (iii) thiosulfate was reduced to sulfide only when pyruvate was the substrate. Comparison of anaerobic growth in the presence or absence of inorganic sulfur compounds indicated true dissimilatory reductions.
