Figure 4. Effect of medium components on the 7-cis-C16:1 content in the JCM 7042 cells. (A) Each of TOS and MRS medium components was added to the MRS and TOS media, respectively, at the concentration of 3.0 g/L for (NH₄)₂SO₄; 0.5 g/L for L-cysteine; 10 g/L for galactooligosaccharide (GOS); 3.0 g/L for K₂HPO₄, 1.0 g/L for Tween 80, 2.0 g/L for ammonium citrate (Citrate); 10 g/L for beef extract; 5.0 g/L for sodium acetate (Acetate); and 20 g/L for glucose; (B) effect of Tween 80 on the 7-cis-C16:1 content and post-culture cell biomass of the JCM 7042 strain.
