Iron-oxidizin1
Examples: Nitrifying bacteria, sulfur-oxidizing bacteria, iron-oxidizing bacteria, Knallgas-bacteria photolithoautotrophs obtain energy from light and carbon from the fixation of carbon dioxide, using reducing equivalents from inorganic compounds. (wikipedia.org)

Putative anaerobic CH4-oxidizing archaea (ANME-2D) and bacteria (NC 10) were scarce (up to 3.4% and 0.5% of archaeal and bacterial 16S rRNA genes, respectively), likely due to the low environmental stability associated with shallow depths. (scilifelab.se)
Carbon dioxide1
Butyrate-producing bacteria (butyrogens) in the human gut usually produce some combination of butyrate, lactate, formate, acetate, and H2 in branched fermentation pathways to manage reducing power generated during the oxidation of glucose to acetate and carbon dioxide. (bvsalud.org)
Heterotrophic3
Most pathogenic bacteria can be viewed as heterotrophic parasites of humans or the other eukaryotic species they affect. (wikipedia.org)
Based on their taxonomy, the deep-dwelling groups were putatively organo-heterotrophic, organo-autotrophic and/or acetogenic and thus may contribute to changes in the lake sediment carbon storage. (scilifelab.se)
A short-term removal of the snow from the ice stimulated algal primary producers and subsequently heterotrophic bacteria. (scilifelab.se)

Instead, the increased EA availability suppressed CH4 production via the outcompetition of methanogens by anaerobically respiring bacteria and via the increased protection of organic matter from microbial degradation induced by Fe3+ and Mn4+. (scilifelab.se)

Lower4
Evidence suggests that energy-depleted, diffusion-dominated subseafloor environments in many cases have lower microbial temperature maxima (60-80 °C) 4 , 5 than environments with advective supplies of external microbial energy substrates. (nature.com)
This apparently lower temperature limit of diffusion-dominated, strongly energy-limited environments is perhaps related to the exponential relationship between temperature and abiotic biomolecule-damaging reactions, e.g. amino acid racemization and DNA depurination 10 . (nature.com)
At the same time, Chlorobiaceae, one of the key photosynthetic bacterial families in anoxic lakes, shifted to lower depths. (scilifelab.se)
Seasonal differences in the community composition of bacteria and phytoplankton were mainly related to changes in observed taxa, while the differences across nutrient treatments within an experiment were due to changes in relative contributions of certain higher- and lower-level phylogenetic groups.
