Growth profiles of Streptomyces ZYJ-6 in a chemically defined medium. The arrow represents sampling time at 60 h in a stable growth state, ensuring that the cell physiology was relatively reproducible. Error bars indicate standard deviations of the three independent samples, some of which are hidden under symbols. Diamonds, biomass [g kg−1]; triangles, glucose [g L−1]; pentagrams, candicidin [mg L−1]
