MG1655 | str. K-12 F– λ– ilvG– rfb-50 rph-1 fnr? | Valine toxicity in absence of isoleucine, due to ilvG frameshift. Partial pyrimidine starvation from polar effects of rph-1 on pyrE causes 9–13% slower growth in minimal medium. Slow growth in M9 galactose (td=200–300 min) Some strain variants have an fnr deletion that causes defects in anaerobic respiration. P1 phage susceptible due to IS in rfb O-antigen biosythesis gene cluster. genome allele variations MG1655 physiology | |||
