	Title	Peptidoglycan and Protein, the Major Cell Wall Constituents of the Obligate Halophilic Bacterium Rhodospirillum salexigens
	Abstract	The obligate halophilic member o f Rhodospirillaceae, Rhodospirillum salexigens, does not con tain lipopolysaccharide in its thin and delicate gram-negative type cell wall. Major constituents are protein (approximately 70% of dry weight) and peptidoglycan (murein).

	Title	Chemical Analysis of Peptidoglycans from Species of Chromatiaceae and Ectothiorhodospiraceae
	Abstract	Rigid layer (sodium dodecylsulfate(SDS)-insoluble cell wall) and peptidoglycan fractions were obtained from the Chromatiaceae (Thiocysüs violacea and Chromatium tepidum) and from Ecto-thiorhodospira vacuolata. Chemical composition of rigid layers from all three species indicated the presence of peptidoglycan-bound protein. Qualitative and quantitative composition of isolated peptidoglycan indicate an Aly-type. meso-Diaminopimelic acid was the only diamino acid found. Direct cross-linkage of peptide side-chains was confirmed by separation of respective dipeptides (M-A ; pm-D-Ala) from partial acid hydrolysates of peptidoglycan. GlcN and MurN of the sugar strands are completely N-acetylated. All peptidoglycan fractions contained small amounts of Gly.

	Title	Partial Lack of N-Acetyl Substitution of Glucosamine in the Peptidoglycan of the Budding Phototrophic Rhodomicrobium vannielii
	Abstract	The rigid layer and peptidoglycan fractions from two strains (A TC C 17100 and R m 5) o f the budding phototrophic Rhodomicrobium vannielii were isolated. Rigid layers of both strains con tain protein in addition to peptidoglycan. They were free o f polysaccharides and fatty acids. The respective peptidoglycan fractions contain glucosam ine, muramic acid, l -and D-alanine, D-glutamic and m eso-diam inopim elic acid in approximately equimolar ratios except for a signifi cant lower relative D-alanine content. A nalysis o f partial acid hydrolysates revealed A 1 '/-type structure of Rhodomicrobium vannielii peptidoglycan (shown with strain ATCC 17100). An about 10—30% lack o f N-acetylation o f glucosam ine was indicated. The degree o f cross-linkage was found to be about 60% . No differences in peptidoglycan com position and degree o f cross-linkage were found between swarmer-and chain-cells as exam ined with strain R m 5.
