[Cellular protrusions of luminescent bacteria and relation of their appearance to cultivation conditions].
The luminescent cells of Photobacterium were studied by electron microscopy in order to establish what caused their sticking together and growth on the glass walls of the vessel during continuous cultivation. Electron microscopy revealed protrusions, of various shape and size, on the cells. The phenomenology of various protrusions, including fimbria, is described, and the effect of cultivation conditions (continuous culture, periodic culture) and growth phases on their emergence was elucidated. The sticking of the cells together and their growth on the glass walls were less expressed at pH between 7.5 and 7.9, when the amount of the cells with the fimbria was the least and they were formed during the later phase of growth.
