Fermentation profiles for strain S. nodosus ZJB2016050. Four profiles are illustrated in the line chart, including the yield of AmB, dry cell weight, pH and residual glucose. The whole process could be divided into four phases, lag phase (0–24 h), exponential phase (24–108 h), stationary phase (108–132 h) and decline phase (132–168 h). Each value is a mean of three experiments. Error bars show standard derivation among three experiments
