HPLC chromatograms of supernatant from glucose pre-incubated C. pyrenoidosa at different stages of incubation. a Initial glucose concentration (RT-8.3 min) of 94.36 mM. b Glucose concentration after 2 h of pre-incubation showing a reduced concentration up to 45 mM. b After harvesting, the peak shifted to RT-8.7 which corresponds to the peak of GlcNAc, depicting the formation of GlcNAc during the attachment process. d HR-LC–MS chromatogram of the supernatant after harvesting glucose pre-incubated C. pyrenoidosa and washed A. fumigatus pellets confirming the presence of GlcNAc (indicated by arrow)
