The family planococcaceae

Abstract

Planococcaceae, a family within the order Bacillales, embraces 14 genera: Bhargavaea, Caryophanon, Chryseomicrobium, Filibacter, Jeotgalibacillus, Kurthia, Paenisporosarcina, Planococcus, Planomicrobium, Rummeliibacillus, Solibacillus, Sporosarcina, Ureibacillus, and Viridibacillus. Members of the family are Gram-variable, spore forming or nonspore forming, and motile or nonmotile; morphology varies from trichomes in case of Caryophanon, filamentous in case of Filibacter to rods or rod-cocci, or spherical rods in case of other genera. Diagnostic amino acid in the peptidoglycan is l-lysine with a peptidoglycan variation of A4α type. Most dominating fatty acids of the family are iso-C15:0 or anteiso-C15:0 or iso-C16:0 or C16:1(ω11c) or anteiso-C17:0 or C16:1(ω7c) alcohol. Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylserine and unidentified phospholipids and glycolipids except in case of Jeotgalibacillus are the predominant lipids. The G+C values of DNA for the family Planococcaceae ranges from 34 to 54 %. Phylogenetically a member of Firmicutes group and is closely related to Bacillaceae.
