Heterogeneity of lipopolysaccharides from Pseudomonas aeruginosa: analysis of lipopolysaccharide chain length.
Lipopolysaccharide (LPS) from smooth strains of Pseudomonas aeruginosa 503, PAZ1, PAO1715, PAO1716, and Z61 was fractionated by gel filtration chromatography. LPS samples from the first four strains, all PAO1 derivatives, separated into three major size populations, whereas LPS from strain Z61, a Pac K799/WT mutant strain, separated into two size populations. When column fractions were applied ...
متن کاملSeparation of Salmonella Typhimurium Bacteria from Water Using MWCNTs Arrays
In this study, Salmonella Typhimurium bacteria removal from polluted water has been investigated using multiwall carbon nanotubes arrays. Experimental results reveal that the contact time, the bacterial concentration and the weight of multiwall carbon nanotubes arrays have positive significant effects on the bacteria removal efficiency. Increasing the contact time and the weight of multiwall ca...
متن کاملMutants Deficient or Altered in Branched-chain-amino- Acid Aminotransferase in Salmonella Typhimurium
In a previous paper (Kiritani and Inuzuka 1970) , it was reported that Salmonella typhimurium mutants deficient in both the branched-chain-amino-acid aminotransferase EC 2.6.1.6 (transaminase B) and the a, j3-dihydroxyacid dehydratase EC 4.2.1.9 required leucine in addition to isoleucine and valine for normal growth, whereas the known mutants deficient in transaminase B require only isoleucine,...
متن کاملInduction of acid resistance of Salmonella typhimurium by exposure to short-chain fatty acids.
Exposure to short-chain fatty acids (SCFA) is one of the stress conditions Salmonella typhimurium encounters during its life cycle, because SCFA have been widely used as food preservatives and SCFA are also present at high concentrations in the gastrointestinal tracts of host animals. The effects of SCFA on the acid resistance of the organism were examined in an attempt to understand the potent...
متن کاملCOMPARATIVE CHARACTERIZATION OF PORINS FROM SALMONELLA TYPHIO-901 AND SALMONELLA TYPHIMURIUM RA-30
Porins from Salmonella typhi 0-901 and Salmonella typhimurium Ra-30 were characterized and compared. The elution profile of porins from these salmonella species on Sepharose-48 and HPLC appear to be very similar. The findings were confirmed by the electrophoretic pattern which showed three types of porins, i.e. OmpC, OmpD and OmpF in both species. These porins appear to be similar, if not ...
