Broth viscosity
Webtonian systems, broth viscosity is shear-rate dependent and, thus, any viscosity correlation must include shear rate to be meaningful. On the other hand, a remarkable effect of viscosity on the productivity has recently been evidenced also in Newtonian systems like those used for starch hydrolysate alcohol fermentation.
