SUMMARY: ATCC 10137, IMRU 3570, JI 2212, JI2236 and . G speculated abundantly in several liquid media after nutritional downshift. Spores formed in submerged cultures were viable and as thermoresistant as aerial spores. Scanning electron microscopy showed that submerged spores are morphologically similar to aerial spores. The sporulation of the strains tested in complex medium appeared to be triggered by phosphate nutritional downshift, induced by addition of Ca to the medium. Spore-shaped bodies were formed by JI 1326 and JI 2280 when grown in complex medium supplemented with Ca and proline. The thermoresistance of these spore-shaped bodies differed from that of aerial spores.
