Planomicrobium koreense gen. nov., sp. nov., a bacterium isolated from the Korean traditional fermented seafood jeotgal, and transfer of Planococcus okeanokoites (Nakagawa et al. 1996) and Planococcus mcmeekinii (Junge et al. 1998) to the genus Planomicrobium.

Abstract

T is considered to represent a new genus and a new species, for which the name Planomicrobium koreense gen. nov., sp. nov. is proposed. It is also proposed that Planococcus okeanokoites and Planococcus mcmeekinii be transferred to the new genus Planomicrobium as Planomicrobium okeanokoites and Planomicrobium mcmeekinii, respectively.

Chryseomicrobium imtechense gen. nov., sp. nov., a new member of the family Planococcaceae

“…Strain MW 10 T had cell-wall peptidoglycan type A4a (L-Lys-D-Asp), which was also reported in species of the genus Paenisporosarcina (Krishnamurthi et al, 2009) and a few species of the genus Planomicrobium (Yoon et al, 2001). However, the peptidoglycan type of strain MW 10 T differed from those of members of the genera Psychrobacillus, Sporosarcina and Planococcus.…”

“…S2). Diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine were also reported as major polar lipids in members of the genera Psychrobacillus, Paenisporosarcina, Sporosarcina, Planococcus and Planomicrobium (Krishnamurthi et al, 2009(Krishnamurthi et al, , 2010Mayilraj et al, 2005;Romano et al, 2003;Suresh et al, 2007;Yoon et al, 2001Yoon et al, , 2010Yu et al, 2008). However, phosphatidylcholine, detected in strain MW 10 T , was not found in closely related genera.…”

“…MK-7 and MK-8 were reported as predominant menaquinones in members of the genera Psychrobacillus, Planococcus, Planomicrobium and Paenisporosarcina (Alam et al, 2003;Choi et al, 2007;Dai et al, 2005;Jung et al, 2009;Krishnamurthi et al, 2009;Zhang et al, 2009) whereas, in members of the genus Sporosarcina, MK-7 was reported as the major menaquinone Yu et al, 2008). MK-6 was also present in minor amounts in some members of the genera Planomicrobium and Planococcus (Yoon et al, 2001(Yoon et al, , 2010). MK-7(H 2 ) was reported in Planococcus columbae (Suresh et al, 2007); however, MK-7(H 2 ) was not present in the genera Psychrobacillus, Paenisporosarcina, Sporosarcina or Planomicrobium.…”

Phylogenetic Analyses of the Genus Hymenobacter and Description of Siccationidurans gen. nov., and Parahymenobacter gen. nov

“…Gram-negative and Gram-positive bacteria contain 713/1542 and 568/1542 nucleotides, respectively, in the highly conserved regions [30], and a total of 145/1542 (9.4%) more nucleotides are conserved in Gram-negative bacteria. Under these circumstances, the difference of 88 to 93% among species of Clade1, Clade2 and Clade3, being Gramnegative by virtue, belonging to the genus Hymenobacter, is huge and demands the creation of new genera [30], since earlier the genera were carved with >92% 16S rRNA gene sequence similarity [7,8,[32][33][34]. The main impediment is the lack of diagnostic phenotypic differences.…”

“…In this context, it is worth mentioning that, based on 16S rRNA gene sequence analyses, five distinct phylogenetic groups within the genus Bacillus [3], two novel orders, Solirubrobacterales and Thermoleophilales [4], and a new hierarchic classification structure for the actinomycete line of descent [5] were proposed and the phylogenetic affiliation of the genus pseudomonads was assessed [6]. In congruence with these, to take few examples, several novel genera, such as Solibacillus [7] and Planomicrobium [8], were created on the basis of their 16S rRNA gene sequence. Present work is focused on evaluating the internal features of the 16S rRNA gene sequences of the genus Hymenobacter.…”
