Inhibition of C. thermocellum growth on cellobiose. Growth of C. thermocellum on cellobiose with the addition of spent broths sampled at various times from a 40 g/L monoculture fermentation on corn fiber. Cultures and measurements of optical density at 600 nm (OD600) were conducted in a plate reader. Spent broth constituted 75% of the cultures by volume, with the remainder being cellobiose, media components, and inoculum
