Each of the four mixed-strain starter
cultures was formulated with one LB strain and one ST strain in
pairwise combinations from the four single strains. Accordingly,
Yog-1 was produced by a starter culture in strain combination of
CHCC-10935 (LB) and CHCC-13140 (ST); Yog-2 by the combination
of CHCC-10935 (LB) and CHCC-3048 (ST); Yog-3 by CHCC-5213 (LB)
and CHCC-13140 (ST); and Yog-4 by CHCC-5213 (LB) and CHCC-
3048 (ST). For all combinations a ratio of 75% ST to 25% LB was
used, as this is in the range normally used in commercial cultures in
order to limit post-acidification.
