Morphology, growth, and protein profile of D. papillatum in different conditions. a Differential interference contrast images showing the altered morphology of D. papillatum cells grown under tested conditions. Scale bar 2.5 μm. b Rosettes formation. c Growth curves of D. papillatum and time-course changes in the mean fluorescence intensity emitted by cells under the tested conditions. Mean fluorescence intensity of cells maintained in rich medium significantly dropped while their concentration remained stable, thus indicating that cells underwent division but some also died. There was no significant difference in concentration of cells maintained in poor media; similarly, their mean fluorescence intensity dropped but insignificantly (p = 0.051), which is likely related to limited cell death. d Protein profiles of D. papillatum grown under tested conditions. Tested conditions: rich (R) and poor (P) media, aerobic (+) and hypoxic (-)
