Re-evaluation of the serotypes of Serratia marcescens and separation into two schemes based on lipopolysaccharide (O) and capsular polysaccharide (K) antigens
Article Abstract:
Several of the 29 O serotype reference strains of Serratia marcescens are shown to contain both neutral and acidic polysaccharides, corresponding to LPS O antigens and capsular K antigens. New O and K antigen typing schemes have been developed aimed at allow specific detection of the antigens on unknown strains using ELISAs. The different aspects of chemical structure were found to be linked with different rates of serological reactivity, but generally, the O antigen repeating unit structures were chemically simple having di- or trisaccharide backbones.

Phenotypic variation of lipid composition in Burkholderia cepacia: a response to increased growth temperature is a greater content of 2-hydroxy acids in phosphatidylethanolamine and ornithine amide lipid
Article Abstract:
Research was conducted to examine the influence of growth rate, growth temperature and growth-limiting nutrients on the polar lipids of Burkholderia cepacia such as phosphatidylethanolamine (PE) and ornithine amide lipid (OL). Results revealed that the rise in growth temperature resulted to a rise the the proportions of PE and OL. The PE:OL ratio were also affected by changes in the growth rate.

Lipid composition and taxonomy of [Pseudomonas] echinoides: transfer to the genus Sphingomonas
Article Abstract:
Lipid analyses of [Pseudomonas] echinoides show that the lipid is composed of non-polar lipids, fatty acids, phospholipids, and glycolipids. Lipid data suggest a reclassification of the organism as Sphingomonas echinoides.
