Figure 3

Electron microscopy analysis of P. alvei endospore formation. DMSO (0.1% v/v) was used as a control (None). 1 mM indole and 1 mM 3-indolylacetonitrile (IAN) dissolved in DMSO were added at the beginning of culture, and cells (an initial turbidity of 0.05 at 600 nm) were grown in DSM for 30 h. The scale bar indicates 500 nm in the upper panel and 100 nm in the lower panel. Abbreviations: SC, spore coat; Cx, cortex; SPC, spore core.
