Figure 4From: Co-production of bioethanol and probiotic yeast biomass from agricultural feedstock: application of the rural biorefinery conceptSterol composition. Overlay of GC-MS sterol chromatograms for turbo yeast (unbroken trace) and MYA-796 (broken trace) grown on GJ + tfosEp. Diagnostic fragmentation spectra for 1) zymosterol, 2) ergosterol and 3) lanosterol are shown; note the presence of minor sterol intermediates (retention times 31.5-34.5 min and 36.5 min).Back to article page
