In the article by Kim et al. that appears in Journal of Microbiology 2012; 50, 354-358. The novel species name Arenimonas aquaticum should be changed as Arenimonas aquatica because the genus name Arenimonas is of the feminine gender. The adjective used as specific epithet must be in the feminine gender as well. In addition, type strain NA-09T =KACC14663T should be changed as type strain NA-09T =KACC14662T.
