Abstract
The budding process of cell division in a bacterial strain (ICPB 4232) belonging to morphotype IV of theBlastocaulis-Planctomyces group was followed in aerobic slide cultures. Under the conditions employed, 3 h elapsed from the appearance of the earliest discernible stage of daughter cell formation to the separation of the mature ovoid bud. Budding invariably occurred at the broader pole of the ovoid, nonmotile mother cell. The separated daughter cell (bud), a motile swarmer, locomoted by means of an ensheathed flagellum attached at its broader pole. Approximately 30 h were required for the swarmer to develop into a sessile mother cell and initiate a new budding cycle. A mother cell was capable of producing an individual bud repeatedly at the same budding site. Transmission electron microscopy was employed to determine ultrastructural details regarding the single ensheathed flagellum, the polarly distributed crateriform structures and numerous pili, the excreted holdfast, the multifibrillar major appendage (a fascicle), and daughter cell (bud) formation.
