The taxonomic status of the genus Planococcus Migula 1894

Planococcus halophilus sp.nov., a Facultatively Halophilic Coccus

“…DISCUSSION Although NRCC 14033 was formerly listed by the NRCC culture collection as ''Micrococcus H5," our previous study of its growth characteristics (16) and our present results support the conclusion that NRCC 14033 is not the "Micrococcus H5)' originally reported by Venkataraman and Sreenivasan (28) We propose placing NRCC 14033 in the genus Planococcus, which includes the motile, nonsporeforming, marine cocci (9,11). Classification was based mainly on the organism's motility, G+C content, and its strict aerobic nature.…”

“…Although all planococci studied previously show good growth in media containing no added salt or seawater medium, only a few could grow in media with 15% NaCl (11). NRCC 14033 cannot normally grow in media without added salt, grows best in 6 to 1296 NaCl, and can grow, albeit poorly, in media saturated with NaCl (16).…”

“…Sections on copper grids were doubly stained with uranyl acetate and Reynolds lead citrate (18). Specimens for flagella measurement (shadow-cast) were prepared by the method described by Kocur et al (11). Electron microscopy was performed with an Applied Electronics Industries EMGB electron microscope operating at a voltage of 60 kV.…”

A new species of Planococcus, P. kocurii isolated from fish, frozen foods, and fish curing brine.

“…Therefore, motile cocci are interesting not only from a taxonomic point of view, but also with regard to food hygiene. This paper deals with the taxonomic studies of motile cocci in the genus Planococcus, and the establishment of a new species, Planococcus kocurii, for the strains with lower DNA base composition reported as group I by KoCUR et al (16).…”

“…BOHACEK et al (15) determined the DNA base composition of some micrococci, and separated motile cocci from non-motile cocci by the composition. KOCUR et al (16) studied taxonomically motile cocci and revived the genus Planococcus Migula 1894. The strains in their group II were identified as Planococcus citreus Migula 1894, and the strains in their group I were kept in this genus as Planococcus sp.…”
