Fig. 2From: Improving cellulase production in submerged fermentation by the expression of a Vitreoscilla hemoglobin in Trichoderma reesei CO-difference spectral analysis of T. reesei TU-6 and TU6-vgb+. CO-difference spectra of mycelia extracts were measured between 400 and 500 nm after bubbling with CO. TU6-vgb+ is shown with a black solid line and TU-6 is shown with a dashed lineBack to article page
