I have some pellets of P chrysosporium grown in PDB and YE for 7 days at 30 degrees. These pellets were washed with phosphate buffer and supplied with an energy source (glucose) for a degradation set-up. I am just wondering which process should I do to extract intracellular and extracellular metabolites to be analysed for q-TOF. I am reading some articles now but of course, people here have had a firsthand experience on this matter. Thank you in advance!
