Effect of aeration modes and their combination on phytosterol transformation by Mycolicibacterium neoaurum VKM Ac-1815D¹. A Transformation was carried out only under the “oxidative” mode; B change of the transformation mode from “oxidative” to “reductive” was conducted at 120 h (vertical line). Red graphs—glucose was added daily throughout transformation period (24–196 h); blue graphs—glucose was not added daily; green graphs—glucose was added throughout “reductive” mode (144–196 h). ¹The initial phytosterol load was 5 g/l. The molar ratio of phytosterol to mCD was 1:0.3. Glucose (10 g/l) was added to the medium M2 at the inoculation moment (0 h) in all cases and additionally as mentioned in legend
