Polska wersja Photos of luminescent bacteria cells

Some photos of luminescent bacteria cells:

There are some photos of luminescent bacteria cells. Sorry, quality of these photos is not good, but I do not have any special equipment. I took the photos of stained cells. I used popular light microscope and special adapter (photographic ring), which make me able to join the microscope and my camera. The photos, which I got were corrected by use of computer graphic programs to get better sharpness and more true colours. I started four cultures of four luminous bacteria species on the petri plates with "BOSS" medium. I prepared two microscopic preparations from each culture in two ways of stain (I used Gram procedure of staining and simple negative staining procedure)

Photobacterium phosphoreum (Vibrio phosphoreum) - photo 1 shows Gram stained bacterial cells. The shapes of them are cylindrical or almost spherical, Gram-negative. Photo 2 shows negatively stained cells - more cylindrical cells are visible. I think that the shapes of some of them are like the bean seed .

Photobacterium luciferum. Cylindrical, Gram-negative cells are visible. Photo 1 shows Gram stained cells and photo 2 shows negative stained cells of this bacterium.

Vibrio fischeri. Photo 1 shows cylindrical cells of this Gram-negative bacterium. Cylindrical shape is more visible when cells are negative stained (photo 2).

Vibrio harveyi cells. Cells are cylindrical, Gram-negative (photo 1). Cylindrical shape is more visible when cells are negative stained (photo 2).
