Editorial: Composition, functions and modulation of gut microbiota in maricultural animals

Abstract

Editorial on the Research Topic Composition, functions and modulation of gut microbiota in maricultural animalsDespite that evaluation of the gut microbiota can be dates to the late 1920`s and early 1930`s (Reed andSpence, 1929;Stewart, 1932;Gibbons, 1933), controversy still existed in the 70s about the existence and role of indigenous microbiota in fish gastrointestinal (GI) tract (Ringø et al., 2016). However, today it is generally accepted that fish gut microbiome, which include e.g., bacteria, fungi and yeast are modulated by dietary components, age, gender, health status and environmental factors (Ringø et al., 2016;Egerton et al., 2018;Bates et al., 2022). The microbiome plays a crucial role in GI development, digestive function, maintaining mucosal tolerance, barrier functions and in the maintenance of its homeostasis, enhance the immune response, provide protection against exogenous microorganisms and diseases (e.g.,

Yeast-extracted nucleotides and nucleic acids as promising feed additives for European sea bass (Dicentrarchus labrax) juveniles

“…A similar overall decrease of LAB species after suboptimal rearing conditions (high temperature and low oxygen) was also described in previous studies (Busti et al, 2020) on European sea bass. In aquaculture species, LAB feed supplementation or their proliferation in GM has been attributed to positive outputs such as improved performance (LeBlanc et al, 2017;Xia et al, 2020), immune response and disease resistance, though their action mechanisms are still poorly understood (Ringo et al, 2018;Sun et al, 2022). After suboptimal condition, dietary NT was also able to increase Bacillus abundance in low fish meal diet.…”
