polynucleobacter campilacus polynucleobacter campilacus polynucleobacter campilacus is an aerobic, catalase- and oxidase-positive, chemo-organotrophic, nonmotile, free-living bacterium of the genus polynucleobacter., the type strain was isolated from lake feldsee located in the southern black forest in germany. the species epithet "campilacus" refers to the origin of the type strain from this lake. the complete genome sequence of the strain was determined. among the described polynucleobacter species, p. campilacus is closest related to p. hirudinilacicola. polynucleobacter campilacus scientific classification domain: bacteria phylum: pseudomonadota class: betaproteobacteria order: burkholderiales family: burkholderiaceae genus: polynucleobacter species: p. campilacus binomial name polynucleobacter campilacushahn et al. 2018 type strain mwh-feld-100, dsm 24007, lmg 29705 synonyms polynucleobacter necessarius subsp. asymbioticus, polynucleobacter sp. mwh-feld-100
