bryocella elongata bryocella elongata bryocella elongata is a bacterium, a type species of genus bryocella. cells are gram-negative, non-motile pink-pigmented rods that multiply by normal cell division and form rosettes. the type strain is sn10(t). b. elongata was first isolated in 2011 from a methanotropic enrichment culture. bryocella elongata scientific classification domain: bacteria phylum: acidobacteriota class: "acidobacteriia" order: acidobacteriales family: acidobacteriaceae genus: bryocella species: b. elongata binomial name bryocella elongatadedysh et al. 2012 phylogeny according to analysis of 16s rrna sequence, bryocella elongata is a member of subdivision 1 of the phylum acidobacteriota. bryocella elongata sn10(t) forms a separate lineage within subdivision 1 of the acidobacteriota and displays 94.0–95.4% 16s ribosomal rna gene sequence similarity to members of the genera edaphobacter and granulicella, 93.0–93.7% similarity to members of the terriglobus and 92.2–92.3% similarity to the type strains of telmatobacter bradus and acidobacterium capsulatum. biology and biochemistry bryocella elongata is an aerobic chemo-organotroph. the growth substrates are sugars and heteropolysaccharides of plant and microbial origin (pectin, lichenan, fucoidan, gellan gum). type strain bryocella elongata sn10(t) was isolated from a methanotrophic enrichment culture obtained from an acidic sphagnum peat. bryocella elongata is not capable of growth on c(1) compounds, but it can develop in co-culture with exopolysaccharide-producing methanotrophs by utilization of their capsular material. bryocella elongata is an acidophilic, mesophilic bacterium capable of growth at ph 3.2–6.6 (optimum at ph 4.7–5.2) and at 6–32 °c (optimum at 20–24 °c).
