[Continuous cultivation of Photobacterium phosphoreum luminescent bacteria with control of the luminescence].

The paper describes a procedure for continuous cultivation of luminescent bacteria Photobacterium phosphoreum according to which the nutrient flow is controlled with respect to the luminescence intensity. The biomass yield of this cultivation procedure at the given luminescence intensity 6.1 X 10(12) quantum X ml-1 s-1 is over three times higher than that obtained in periodic cultivation, with the specific cell luminescence being identical in both cases. The cultivation process is unstable at the luminescence intensity 4.1 X 10(12) quantum X ml-1 s-1 and the glycerol content in the nutrient medium over 6 g/l. Practical applications of the above procedure for the cultivation of luminescent bacteria are discussed.
