Abstract:The lipopolysaccharide (LPS) of 3 recently identified antibiotic‐supersensitive mutants of Salmonella typhimurium was analyzed and compared to the parent. The amounts of glucose, galactose, heptose, 2‐keto‐3‐deoxyoctonate, total phosphorus, total amino groups, and fatty acids were similar in all of the LPS preparations, and typical of the chemotype Rb2 of the rfaJ parent. Sodium dodecyl sulphate‐polyacrylamide gel electrophoresis (SDS‐PAGE) did not reveal any differences between the mutants and the parent. Eth… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
