Fig. 2

Screening of eight secretomes of L. starkeyi transformants for each fusion protein by Western blot. The top panel shows a Western blot, and the bottom panel shows the corresponding SDS-PAGE gel. a The secretomes from transformants expressing Fusion 1, b for Fusion 2, and panel C for Fusion 3. The lane having Ls8-7 shows the secretome from a transformant having the individual TeTrCBHI construct.
