Fig. 4From: Rapid sample processing for intracellular metabolite studies in Penicillium ochrochloron CBS 123.824: the FiltRes-device combines cold filtration of methanol quenched biomass with resuspension in extraction solutionFilter cake of glucose-limited chemostat mycelium quenched in pure methanol and filtrated with the FiltRes-device. a Mycelial filter cake in the extraction solution after transfer into the tubes. b Still intact mycelial filter cake after rigorous shaking of the test tube. Note the difference to mycelium quenched in 60 % methanol, which quickly disperses in the extraction solution with the same treatment (illustrated in Additional file 2: Movie S1)Back to article page
