Abstract
Dormant cysts of Azotobacter vinelandii germinated at 30 degrees C in Burk nitrogen-free media containing 1% glucose. Samples taken at intervals and examined by electron microscopy revealed that as germination progressed, vesicle-like and fibrillar structures became visible in the intine region. Lamellae associated with the cell membrane appeared in the central body at 6 h post-initiation of germination. Both electron micrographic and chemical analysis showed that the poly-beta-hydroxybutyrate content of cysts decreased significantly after 4 h of germination. Dormant cysts were resistant to sonic oscillation, but this property was lost during their conversion to metabolically active vegetative cells.
