Proposed Taxon Etymology Description Parent Taxon Type Registry URL
Genus Macondimonas ['nas] L. fem. n. monas, a unit, a monad; N.L. fem. n. Macondimonas, a monad from Macondo, Macondo Prospect, the site of DWH oil spill. Additionally, Macondo is a fictional town in A Hundred Years of Solitude by G. García Márquez. In the book, the town of Macondo has a rapid population growth, a period of economic prosperity, and then a rapid population fall, which is reminiscent of the ecologic pattern observed for this group upon crude-oil exposure
Members of this genus exhibit a coccobacilli morphology and a heterotrophic aerobic metabolism. No phototrophic, nor chemoautotrophic growth, or their corresponding genes in the genome were observed. The type species is Macondimonas diazotrophica.
Ectothiorhodospiraceae Macondimonas diazotrophicaTs
Species Macondimonas diazotrophicaTs [di.a.zo.tro'] Gr. pref. di-, in two; N.L. neut. n. azotum, from Fr. n. azote (from Gr. prep. a, not; Gr. n. zôê, life; N.Gr. n. azôê, not sustaining life), nitrogen; N.L. pref. diazo-, pertaining to dinitrogen; Gr. adj. trophikos -ê -on, feeding, tending; N.L. fem. adj. diazotrophica, one that feeds on dinitrogen, named after its ability to fix atmospheric nitrogen
Cells grown on solidified mineral artificial seawater media using hexadecane as substrate show a coccobacillus morphology, of about 0.6 μm in length and 0.35 μm in width, and formed circular colonies. Members of the species are aerobes, growing at a pH range of 6.5–8.5 with a pH optimum of 7.5, and a salinity range of 250–500 mM of NaCl, with an optimum concentration of 330 mM. The temperature range for optimal growth is 22–30 °C, with no growth observed at 4 °C and above 34 °C. Cells can grow with hexadecane and pyruvate as a sole carbon sources and fix nitrogen. Genome size is ~2.8 Mbp with a G+C% content of 61.56. The designated type material is strain KTK01, and its genome sequence can be found under NCBI BioSample accession number SAMN11302943.
