Abstract: 

Ge.or.gen'i.a. N.L. fem. n. Georgenia referring to the village St Georgen in Styria (Austria), where strains 1A-C^T and 3A-1 were isolated.

Actinobacteria / Actinobacteria / Micrococcales / Bogoriellaceae / Georgenia

The genus Georgenia was originally described for two Gram-stain-positive, yellow-pigmented strains, which had been isolated from a medieval wall painting in St Georgen, Styria, Austria (Altenburger et al., 2002). Currently nine validated species are proposed. Cells may exhibit a rod-coccus growth cycle. Phylogenetically, the genus is a member of the family Bogoriellaceae, order Micrococcales, class Actinobacteria. Rods and cocci occur singly or in small clusters. Cells are gram-stain-positive, nonspore forming, motile, and nonmotile. Growth occurs under both aerobic and anaerobic conditions. Oxidase positive or negative, catalase positive. Peptidoglycan type is A4α with l-Lys←l-Glu or l-Lys–l-Ala–l-Glu or l-Lys–Gly-L–Glu or l-Lys←Asp as the interpeptide bridge. Quinone system is menaquinone MK-8(H4). Polar lipids are diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol mannoside, or phosphatidylinositol together with unidentified phospholipids, and one unknown glycolipid. The predominant fatty acid is anteiso-C_15:0; significant amounts of anteiso-C_15:1, iso-C_15:0, and iso-C_14:0 are present. The polyamine content is low. Major polyamines are spermidine and spermine. The genomic G+C content varies between 70 to 73 mol%.
