Identification of Salmonella enterica serovar Typhimurium genes associated with growth suppression in stationary-phase nutrient broth cultures and in the chicken intestine.

abstract：:Expression of unnecessary proteins is known to reduce the growth rate of Escherichia coli. This reduction in growth rate, due to the diversion of cellular resources from making essential proteins, is called cost. Cellular resources depend upon the macromolecular content of the cell. Cost phenomenon lies in the process...
