Comparison of dried/ensiled hydrolysates for TAL production, both with and without filtering hydrolysates prior to fermentation. A Titers obtained during fermentation on filtered hydrolysates over time. B Growth in filtered hydrolysates, as measured by optical densities. C Primary carbon sources during fermentation on filtered hydrolysates, at the experiment start and end. D Titers obtained during fermentation on unfiltered, pasteurized hydrolysates over time. E Growth in unfiltered hydrolysates, as measured by viable colony forming units (CFUs) of R. toruloides on YPD plates. The limit of detectable colony units is indicated (1000 units/mL). F Primary carbon sources during fermentation on unfiltered hydrolysates, at the experiment start and end. All error bars represent standard deviations of biological triplicates
