[1] In a study on the cultivation of microbial communities in sludge, where sulphate reducers are likely to benefit, the proportion of Geopsychrobacter decreased.
[3] An investigation of bacterial diversity in the cold outflow of an iron oxide-tainted plume of saltwater (Blood Falls, Antarctica) indicated about 11% of cells as G.
[4] The plume were identified as a subglacial “ocean”, where coupled biogeochemical processes below the glacier enable microbes to grow in extended isolation, accumulating iron(II) despite the presence of an active sulfur cycle.
[1] One key point of harvesting energy using a sediment fuel cell seems to bridge the anaerobic environment of G. electrodiphilus and the aerobic water; the difference in redox potentials can be used.
[1] It is therefore conceivable that the oligodynamic effect in Geopsychrobacter is low and an application with metallic components inside a technical device would be possible.
