Piromyces sp. UH3-1 grows on diverse feedstocks: a growth of UH3-1 on soluble substrates leads to colony formation on the walls of the tubes (arrows indicating colony formation). Fungal cultures growing on lignocellulosic substrates float up during fermentation. b A representative growth curve of UH3-1 on corn stover. c, d Piromyces sp. UH3-1 degrade and proliferate on a wide array of untreated agricultural wastes, bioenergy feedstocks, and forestry wastes. All accumulated pressures are normalized to glucose. Asterisks denote statistically significant differences in specific growth rate relative to glucose (p < 0.05, unpaired t test)
