Fig. 3From: Evaluation and optimisation of direct transesterification methods for the assessment of lipid accumulation in oleaginous filamentous fungiFTIR spectra of fungal biomass before and after direct transesterification (Lewis 2 method with 90 min reaction time), and of model compounds (glyceryl trioleate, chitin, glucuronate, and sodium polyphosphate). Spectra are plotted with an offset for better viewingBack to article page
