  1. Fatty Acid Degradation in Escherichia Coli and Salmonella Enterica Serovar Typhimurium

    Iram, Surtaj H.University of Illinois at Urbana-Champaign2015

    Wild type strains of S. enterica grow on decanoic acid whereas wild type E. coli strains cannot. Mutant strains (fadR) of both organisms are readily isolated in which the genes (fad) of fatty acid degradation are expressed constitutively. The S. enterica fadR strains grow more rapidly than the wild …
