“…In addition to the importance of investigation on their ecological role, different biotechnological and industrial applications of luminous bacteria have recently been highlighted. For instance, bioluminescent bacteria were proposed as indicators or biosensors for measuring the pollution level and toxicity of chemicals in environmental samples or for detecting possible DNA-tropic and oxidative stress-causing agents [79][80][81].…”

Luminescent bacteria are a fascinating component of marine microbial communities, often related to the light emissions in deep sea marine organisms. They are mainly affiliated with specific phylogenetic groups, such as Photobacterium, Vibrio, and Photorhabdus, and are sometimes involved in symbiotic relationships. However, the luminescence of some marine organisms remains a poorly understood process, and it is not always certain whether their luminescence is attributable to associated luminescent bacteria. In this study, for the first time, luminescent bacteria were isolated from two deep sea organisms, namely, the cephalopod Neorossia caroli and the teleost Chlorophthalmus agassizi. The isolation was carried out on glycerol-supplemented medium, and the search for the luxAB gene was performed on all isolates as a complementary tool to the culture-dependent techniques to detect bioluminescence by molecular approach. The optimum of salinity, temperature, and pH was evaluated by physiological tests for all isolates. The production of extracellular polymeric substances was also preliminarily screened. A total of 24 luminescent isolates were obtained, with an abundance from C. agassizi specimens. All the isolates were taxonomically characterized and were related to different species of Photobacterium, with the exception of Vibrio sp. CLD11 that was from C. agassizi. The luxAB gene was detected in about the 90% of the analysed strains.

“…And, the released bacteria recolonize new generations of the same host [128], or may colonize other luminous and non-luminous organisms [120,125,129]. Anomalopidae, monocentrid fish, and angler fish are known to release luminous bacteria from their light organs and intestine excretions into the external environment and maintain the bacterial count in their light organs [125,126]. Cardinal fish Siphamia releases luminous feces composed of luminous bacteria cultured in the light organ, connected to its digestive tract [127].…”

“…Hence, fish feces appear to be an important source of viable luminous bacteria in the marine environment and could affect both the distribution and the species composition of luminous populations. The luminescence of fecal particles has been reported numerous times and is always associated with luminous bacteria, due to the observation of continuous light emission or direct isolation (Andrews et al, 1984;Ramesh et al, 1990;Raymond and DeVries, 1976;Ruby and Morin, 1979;Zarubin et al, 2012).…”

Abstract. Around 30 species of marine bacteria can emit light, a critical characteristic in the oceanic environment is mostly deprived of sunlight. In this article, we first review current knowledge on bioluminescent bacteria symbiosis in light organs. Then, focusing on gut-associated bacteria, we highlight that recent works, based on omics methods, confirm previous claims about the prominence of bioluminescent bacterial species in fish guts. Such host–symbiont relationships are relatively well-established and represent important knowledge in the bioluminescence field. However, the consequences of bioluminescent bacteria continuously released from light organs and through the digestive tracts to the seawater have been barely taken into account at the ecological and biogeochemical level. For too long neglected, we propose considering the role of bioluminescent bacteria and reconsidering the biological carbon pump, taking into account the bioluminescence effect (“bioluminescence shunt hypothesis”). Indeed, it has been shown that marine snow and fecal pellets are often luminous due to microbial colonization, which makes them a visual target. These luminous particles seem preferentially consumed by organisms of higher trophic levels in comparison to nonluminous ones. As a consequence, the sinking rate of consumed particles could be either increased (due to repackaging) or reduced (due to sloppy feeding or coprophagy/coprorhexy), which can imply a major impact on global biological carbon fluxes. Finally, we propose a strategy, at a worldwide scale, relying on recently developed instrumentation and methodological tools to quantify the impact of bioluminescent bacteria in the biological carbon pump.
