文摘

•: Open fermentation of l-lactic acid with high efficiency from SSJ was developed.
•: Mixed fermentation of B. coagulans and L. rhamnosus were investigated.
•: Stepwise controlled pH was adopted for contamination suppression.
•: Product titer, yield and productivity were 121 g L⁻¹, 94.6% and 2.18 g L⁻¹ h⁻¹.
•: CSP substituting YE & salts was proved an efficient supplement for SSJ.
