The strains of bioluminescent bacteria isolated from the White Sea finfishes: genera Photobacterium, Aliivibrio, Vibrio, Shewanella, and first luminous Kosakonia

Acquisition of bioluminescent trait by non-luminous organisms from luminous organisms through various origins

“…The Photobacterium toruni also might obtain lux genes via HGT. Nonluminous bacterial strains of Kosakonia [43] and Kurthia sp. are thought to acquire lux genes through HGT to emit luminescence [44].…”

Structure-Function Relationships in Temperature Effects on Bacterial Luciferases: Nothing Is Perfect

“…Cold adapted representatives can be found in all known genera except the mentioned Photorhabdus . Recent studies also revealed several dozens of psychrophilic luminous strains, including first luminous Kosakonia cowanii , associated with the digestive system of fishes from the White, Okhotsk, and Bering Seas [ 14 , 15 ]. Thus, luminous bacteria have adapted to a wide range of temperatures, from near zero to about 35 °C, although thermophilic species have not been identified.…”

“…Each group comprises luciferases with the similar type of decay kinetics in reaction with dodecanal: “fast” type from the Aliivibrio and Photobacterium species, and “slow”—from Vibrio and Photorhabdus [ 21 , 22 , 23 ]. The majority of known psychrophilic luciferases belong to the group with the fast decay kinetics, however a few species with “slow” luciferase were also isolated from the northern latitudes, for example, Vibrio splendidus [ 15 ]. The presence of both types of luciferases among psychrophilic strains suggests that either luciferases acquired the properties of cold-active enzymes, regardless of the structural features of the active center, or the adaptation of luminous bacteria passed through a change in the other cellular components and did not affect the bioluminescent system.…”

Novel Viruses That Lyse Plant and Human Strains of Kosakonia cowanii

“…In animals, it has been found to inhabit the gut of the tropical Anopheles gambiae mosquito [ 7 ], as well as the gut of bees ( Apis mellifera mellifera ) hibernating under snow [ 8 ]. It was isolated from the intestine of Atlantic codfish ( Gadus morhua ) from the subpolar White Sea [ 9 ] and from nasal aperture of kea parrot ( Nestor notabilis ). In human, several strains of K. cowanii and K. radicincitans species have been isolated from clinical samples, including of blood, urine, bile, and sputum [ 2 , 10 , 11 ].…”
