Etude des lipides de la forme L stable de Protéus P 18: Identification des acides gras de la fraction acétonosoluble

Comparison of Lipids and Lipopolysaccharide from the Bacillary and L Forms of Proteus P18

“…AMore recently, several workers investigated the lipids of the Proteus L form with various conditions of growth and extraction. Krembel (1963) confiimed the fourfold difference observed earlier, but investigations by other workers (Rebel et al, 1960;Rebel, Bader-Hirsch, and Mandel, 1963;Smith and Rothblat, 1961) showed that the L form contained twice as much total lipid as the parent bacterium. Evaluation of these studies is difficult because of use of undefined growth media and/or cells harvested after lprolonged growth.…”
