FIG 1.

S. albus ZD11 prefers soybean oil to glucose as a carbon source. (A) Salinomycin yield in the liquid medium with soybean oil or glucose containing equimolar amounts of carbon (2.7 M). (B) Consumption of soybean oil or glucose in the liquid medium at 120 h. (C) Salinomycin yield in the liquid medium with different concentrations of carbon sources at 120 h. (D) Comparison of cell growth among different Streptomyces strains in the oil medium containing 2.7 M carbon. Error bars indicate the SD for samples tested in triplicate.
