Abstract

Psychrophilic pigment-forming strains, isolated from Lake Baikal and the Pokhabikha River, were studied. Based on culture-based, morphological, and biochemical properties, as well as the results of 16S rRNA gene sequence analysis, the studied bacteria were assigned to the genera Janthinobacterium and Iodobacter. The strains are able to form biofilms and produce violet pigment. When the pigments were extracted with methanol and identified by MALDI/TOF mass spectrometry, the pigments violacein and deoxyviolacein were identified.
