(Hyphomicrobium neptunium) JF International Journal of Systematic and Evolutionary Microbiology, VO 34 IS 1 SP 71 OP 73 DO https://doi.org/10.1099/00207713-34-1-71 PB Microbiology Society, SN 1466-5034, AB We present evidence in support of revival of the genus Hyphomonas Pongratz 1957 and emend the description of this genus. The type species is Hyphomonas polymorpha nom. rev., with type strain PS728 (= ATCC 33881 = IFAM PS728). A second strain of Hyphomonas polymorpha, strain PR727 (= ATCC 33880 = IFAM PR727), is also recognized. Transfer of a related organism, Hyphomicrobium neptunium strain LE670 (= ATCC 15444 = IFAM LE670), to the genus Hyphomonas is formally proposed., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-34-1-71
