Phenotypically, strains AR4(T), SOP9 and LAY were most similar to Methylocella species, but differed from members of this genus by cell morphology, greater tolerance of low pH, detectable activities of RuBP pathway enzymes and inability to grow on multicarbon compounds.

It is demonstrated that temperature exerts a strong control on microbial diversity when considered over most of the temperature range within which life is possible.
Methanotrophic bacteria in oilsands tailings ponds of northern Alberta
The SIP-PCR results demonstrated that the Methylocaldum and Methylomonas spp.
Photosynthetic isotope biosignatures in laminated micro-stromatolitic and non-laminated nodules associated with modern, freshwater microbialites in Pavilion Lake, B.C.
Global metagenomic survey reveals a new bacterial candidate phylum in geothermal springs
Genome reconstruction indicates a heterotrophic lifestyle with conspicuous nutritional deficiencies, suggesting the need for metabolic complementarity with other microbes, and co-occurrence patterns identifies a number of putative partners, including an uncultured Armatimonadetes lineage.
Constraining carbon sources and growth rates of freshwater microbialites in Pavilion Lake using 14C analysis
The results demonstrate that the microbialites are actively growing and that the primary carbon source for both microbial communities and recent carbonate is DIC originating from the atmosphere, consistent with the previously hypothesized biological origin of the Pavilion Lake microbialites.
Metagenomic Analysis Suggests Modern Freshwater Microbialites Harbor a Distinct Core Microbial Community
The findings suggest that the Pavilion Lake microbialite community profile, metabolic potential and pathway distributions are distinct from those in the neighboring sediments and water, and reveals the distinct nature of these complex communities.

The results indicate that some uncultured bacteria in soils may be adapted to using complex heteropolysaccharides for growth and suggest that the use of these substrates may provide a means for culturing new species.

The results suggest that diverse methanotroph groups are adapted to warm environments, including the Methylocapsa-Methylocella- Methyloferula group, which has previously only been detected in cooler sites.

Molecular analyses show that the microbial communities of Pavilion Lake microbialites are diverse compared to non-lithifying microbial mats also found in the lake, suggesting something other than community changes may be a key to observed variations in microbialite structure.
