L. starkeyi secretome endoglucanase activity with Congo red staining. Secretomes, as culture supernatant from transformant cultures, were used directly for Congo red testing. TrEGII, TeTrCBHI, Fusion 1, Fusion 2, and Fusion 3 show secretomes from transformants integrated with TrEGII, TeTrCBHI, Fusion 1, Fusion 2, or Fusion 3 constructs, respectively. Parent indicates the WT L. starkeyi transformant with empty vector
