Table 1.

Expression cassette copy number and rProPG-1 expression level.

PP-ProPG-1 clone rProPG-1 (24 h) rProPG-1 (72 h) Copy #
Pro4 - + 11
Pro22 + +++ 14
Pro44 ++ +++ 7
Pro50 - - 1

Supernatant samples at 24 and 72 h methanol induction from small-scale fermentations of different PP-ProPG-1 clones were assessed for rProPG-1 expression. (-) indicates no rProPG-1 was detected and (+), (++), (+++) indicate low, medium and high levels of rProPG-1 detected using dot blot analysis, respectively.
