title: [Genetic studies of Photobacterium mandapamensis. II. The classification of mutants with an altered luminescence intensity according to their sensitivity to exogenous aldehyde].
abstract: The collection of 157 dark and dim Photobacterium mandapamensis strains was divided into four groups using the addition of 0.2 ml of 0.15% myristis aldehyde to cell suspension. The luminescence did not change in the presence of the aldehyde in 76 mutants, it decreased in 30 mutants, it was 2--8-fold increased in 35 mutants, and it was increased more than 10-fold in 16 mutant strains. 19 strains of those having luminescence in the presence of the aldehyde have mutations in genes controlling the biosynthesis of the aldehyde factor. Among them mutants are chosen which can be used as indicators for the aldehyde presence in the medium.
