C. beijerinckii BAS/B3/I/124

80.6 ± 4.7

69.1 ± 5.2

C. beijerinckii NCP 260

37.1 ± 0.8

  1. aValues are the average of five independent measurements ± SD
  2. Phosphotransbutyrylase (PTB) activity was determined according to Andersch et al. [57] in CGM cultures of the late strain NCP 260 and the early strain BAS/B3/I/124. The strain NCIMB 8052 was used as a reference
