Correlation between the expression of an Escherichia coli cell surface protein and the ability of the protein to bind to lipopolysaccharide.

abstract：:Spectinomycin-resistant (Spcr) mutants of Escherichia coli were isolated from nutrient agar plates containing 20% sucrose and 100 mug of spectinomycin per ml. About one-third of the Spcr mutants thus obtained were sucrose dependent (Sucd) and were classified into two types: I, those unable to grow on sucrose-free medi...
