  • a Viability of A. laidlawii, M. orale, and M. arginini after S/D treatment. Mycoplasma-spiked harvested cell culture fluid was treated with standard S/D concentration of 0.1% Tri(n-butyl) phosphate (TNBP) and 0.5% Tween 80 solution; 100x diluted S/D was used as a sub-optimal comparator control. Complete inactivation of M. arginini was observed after 60 min. A. laidlawii data from Wang et al., 2017, used with permission.

  • b LRV is log reduction value. > indicates no visible mycoplasma colonies present.

  • c TNBP is Tri(n-butyl) phosphate.
