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 A4alfa type Most dominating fatty acids of the family are iso-C_15:0 or anteiso-C_15:0 or iso-C_16:0 or C_16:0(omega11c) or anteiso-C_17:0 or C16:1(omega7c) 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.
