Bioluminescence is an interesting phenomenon of production of light, wich occurs in various life forms like bacteria, fungi and animals.
Bacteria are the most numerous bioluminescent orga-nisms. It is interesting that the majority of these organisms live in marine environments. This thesis deals with the isolation and determination of the bioluminescent bacteria from hake (Merluccius merluccius).
The freshly caught hake (Merluccius merluccius) was held in the refrigerator on 4˚C for 24 hours. After that period the isolation was done.
The bioluminescent bacteria colonies were producing intensive greenish – blue light. The results obtained by the research of the morphological and biochemical features showed that the light producing bacteria is Vibrio fischeri,which in certain conditions could cause disease in some invertebrates, i.e. deterioration of the caught fish.
