      Ringø, Einar; Harikrishnan, Ramasamy; Soltani, Mehdi; Ghosh, Koushik (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-03)
      The present paper presents an overview of the effects of gut microbiota and probiotics on lipid-, carbohydrate-, protein- and amino acid metabolism in fish and shrimp. In probiotic fish studies, the zebrafish (Danio rerio) model is the most frequently used, and probiotic administration reveals the effect on glucose homeostasis, anti-lipidemic effects and increasing short-chain fatty acids, and ...
    • Extracellular tannase-producing bacteria detected in the digestive tracts of freshwater fishes (Actinopterygii: Cyprinidae and Cichlidae) 

      Talukdar, Sandipan; Ringø, Einar; Ghosh, Koushik (Journal article; Tidsskriftartikkel; Peer reviewed, 2016)
      Background. Although, presence of tannase-producing and/or tannin tolerant gut bacteria has been documented in ruminants and non-ruminant herbivores, the topic is rarely addressed in fi sh. The present study aimed at enumeration of autochthonous tannase-producing bacteria in the gut of freshwater teleosts. <p> Materials and methods. This study covered seven freshwater teleost fi sh species: rohu, ...
    • Fungi and Actinobacteria: Alternative Probiotics for Sustainable Aquaculture 

      Ghosh, Koushik; Harikrishnan, Ramasamy; Mukhopadhyay, Abhisek; Ringø, Einar (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-25)
      Aquatic animals are continually being exposed to stressors under farming conditions, increasing risks to gut health that result in dysbiosis. Since restrictions are imposed on the frequent use of antibiotics in aquaculture, there is emerging demand for economically viable, environmentally safe, and sustainable alternatives for the intensive production of aquaculture species. The application ...
    • Genus bacillus, promising probiotics in aquaculture: Aquatic animal origin, bio-active components, bioremediation and efficacy in fish and shellfish 

      Soltani, Mehdi; Ghosh, Koushik; Hoseinifar, Seyed Hossein; Kumar, Vikash; Lymbery, Alan J.; Roy, Suvra; Ringø, Einar (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-07)
      Species of <i>Bacillus</i> are spore-forming bacteria that are resistant to aggressive physical and chemical conditions, with various species showing unusual physiological features enabling them to survive in various environmental conditions including fresh waters, marine sediments, desert sands, hot springs, Arctic soils, and the gastrointestinal tract of finfish and shellfish. They are able to ...
    • Interesting Probiotic Bacteria Other Than the More Widely Used Lactic Acid Bacteria and Bacilli in Finfish 

      Ringø, Einar; Li, Xuemei; Doan, Hien van; Ghosh, Koushik (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-02)
      Growing demands stimulate the intensification of production and create the need for practices that are both economically viable and environmentally sustainable. As European Union banned the use of antibiotics in production in 2003, several alternative treatments have been suggested, including probiotics. The first probiotic study in aquaculture was published in 1986, and since then probiotics ...
    • Lactic acid bacteria in finfish - An update 

      Ringø, Einar; Hoseinifar, Seyed Hossein; Ghosh, Koushik; Doan, Hien Van; Beck, Bo Ram; Song, Seong Kyu (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-10)
      A complex and dynamic community of microorganisms, play important roles within the fish gastrointestinal (GI) tract. Of the bacteria colonizing the GI tract, are lactic acid bacteria (LAB) generally considered as favorable microorganism due to their abilities to stimulating host GI development, digestive function, mucosal tolerance, stimulating immune response, and improved disease resistance. ...
