Seafood is highly perishable, presenting a rapid loss of its quality soon after capture. Temperature is the critical parameter that impacts on seafood shelf-life reduction, allowing the growth of foodborne pathogens and spoilage microorganisms. In recent years, the search by additional methods of preserving seafood has increased, able to ensure quality and safety. Several natural preservatives have highlighted and gained considerable attention from the scientific community, consumers, industry, and health sectors as a method with broad action antimicrobial and generally economical. Natural preservatives, from different sources, have been widely studied, such as chitosan from animal sources, essential oils, and plant extracts from a plant source, lactic acid bacteria, and bacteriocins from microbiological sources and organic acid from different sources, all with great potential for use in seafood systems. The ocean supports a rich biodiversity, of which bacteria comprise a vast number. Exploration of the ocean for novel bacteriocins is built on the idea that because marine habitat is an extreme environment, highly competitive marine bacteria could produce more potent bacteriocins as compared to compounds isolated from other sources. This review provides updated information about the production, mode of action and applications of marine bacteriocins in seafood preservation. In addition, the actual and potential applications of marine bacteria and their bacteriocins in aquaculture and briefly on the potential uses in other fields have been discussed. Moreover, literature data from isolation, biochemical characterization, and antimicrobial assay reports have also been integrated to provide a contemporary understanding of marine bacteriocin potentials., REVUE DE L���ENTREPRENEURIAT ET DE L���INNOVATION, Vol. 3, No 10 (2021)

Hypersaline environments are extreme habitats on the planet and have a diverse microbial population formed by halophilic microorganisms. They are considered to be actual or potential sources for discovery bioactive compounds, compatible solutes including novel and/or extraordinarily enzymes. To date, a number of bioactive compounds for the use in various fields of biotechnology which show assorted biological activities ranging from antioxidant, sunscreen and antibiotic actions have been reported. In addition, some halophilic microorganisms are capable of producing massive amounts of compatible solutes that are useful as stabilizers for biomolecules or stress-protective agents. The present review will impart knowledge and discuss on diversity of halophilic bacteria and their use in various biotechnological applications, including industrial, pharmaceutical, agricultural and environmental aspects. Culture dependent as well as culture independent methods for isolation of halophiles should go hand in hand to provide the insight mechanisms of halophilic adaptation and their future applications., REVUE DE L���ENTREPRENEURIAT ET DE L���INNOVATION, Vol. 3, No 10 (2021)
