When enterobacterium, Escherichia coli B was cultivated with normal media in the presence of $0.2{sim}0.6%$ Palmitoylcarnitine and $0.05{sim}0.2%$ Ginseng Saponin, maximum population growth of the bacteria was presented 71% and 31%, respectively. Such a result, in vitro test, was concluded from the result that both detergents stimulated $C^{14}$-glucose, $C^{14}$-alanine and $C^{14}$-phosphatidylethanolamine uptake into the membrane of cells. The pre-treatment of cells with different amounts of Palmitoylcarnitine from $0.005{sim}0.05{mu}$ moles represented a significant increase of uptake, 33% of $C^{14}$-glucose, 129% of $C^{14}$-alanine and 158% of phosphatidylethanolamine at the concentration of $0.05{mu}$ moles of Palmitoylcarnitine. On the other hand, the result of $C^{-2}%$ Saponin treatment showed the maximum value of uptake, 17% of $C^{14}$-glucose and 112% of $C^{14}$-alanine. In case of $C^{14}$-phosphatidylethanolamine, the maximum uptake showed 25% of increase at the concentration of $C^{14}$% Saponin.
