“…Lactococcus lactis and various other LAB species have been previously reported as indigenous microflora in different species of sturgeon (Mahious, Vanhoute, De Brandt, Huys & Ollevier ; Askarian, Kousha & Ringø ). Lactococcus lactis has been used in several probiotic studies and showed the ability to inhibit the growth of fish pathogens to a various extent (Balcázar, Vendrell, Blas, Ruiz‐Zarzuela, Gironés & Múzquiz ; Balcázar, Vendrell, Blas, Ruiz‐Zarzuela, Muzquiz & Gironés ; Zhou, Wang, Yao & Li ).…”

To select and characterize potential probiotic bacteria from the gut microbiota of Siberian sturgeon (Acipenser baerii), 129 strains isolated from the hindgut were screened for antagonistic activity against five fish pathogens. Ten isolates showed antagonism towards three or more pathogens. Nine of these isolates were Gram-positive, belonging to Lactococcus (seven) and Bacillus (two), and a single strain belonging to the Gram-negative Citrobacter. These inhibitory isolates were identified using genetic, phentotypic and biochemical traits, and further characterized by in vitro tests assessing the adhesion and growth in mucus and resistance to gastric and intestinal fluids. The candidate probiotics were determined to be non-pathogenic through an in vivo study. Based on these assays, Lactococcus lactis ssp. lactis STG45 and STG81 showed the broadest inhibitory potential, a high viability in simulated gastrointestinal juice and the highest adhesion capacity to mucus. They were therefore selected as the most promising candidate probiotics. This is the first study screening probiotics among the gut microflora of Siberian sturgeon.

“…This topic is highly relevant to evaluate as the intestinal tract, where digestion and absorption take place, is very important for fish. The first aim of this study was therefore to investigate the effect of two LAB, Lactobacillus curvatus and Leuconostoc mesenteroides originally isolated from the GI tract of beluga and Persian sturgeon, respectively (Askarian et al. 2009), on growth, survival and digestive enzyme (amylase, lipase and protease) activities.…”

The aims of this study was to assess the effect of two lactic acid bacteria (LAB), Lactobacillus curvatus and Leuconostoc mesenteroides, originally isolated from gastrointestinal (GI) tract of beluga (Huso huso) and Persian sturgeon (Acipenser persicus), respectively, on growth, survival and digestive enzyme (amylase, lipase and protease) activities and the population level of LAB in the GI tract. The treatments included 10 different groups; control, separate supplements of L. curvatus and Leu. mesenteroides at three different counts [2 · 10 9 , 5 · 10 9 and 9 · 10 9 colony forming units (CFU) per gram food] and three combinations of the two LAB (2 · 10 9 + 2 · 10 9 , 5 · 10 9 + 5 · 10 9 and 9 · 10 9 + 9 · 10 9 CFU per gram food). The bacteria used in this study were added in lyophilized form to chopped Chironomidae. In the beluga study, highest specific growth rate, survival and improved intestinal enzyme activities were noted in the rearing group fed 9 · 10 9 L. curvatus per gram food. In Persian sturgeon, the inclusion level of 2 · 10 9 Leu. mesenteroides had similar positive effect. The ability of LAB to colonize the digestive tract seems to involve host specificity, and our bacteriological results are relevant to initiate future probiotic studies in sturgeons and future directions will be discussed.

This study addressed the issue of the dietary supplements; probiotic, prebiotic and synbiotics considered as functional food ingredients in sturgeon aquaculture. Developments of this strategy have been suggested and practiced as an alternative to antibiotic administration in aquaculture. Sturgeons are commercially valuable species due to their meet and roe, which is made into caviar. Aquaculture of sturgeons up to marketable size has increased during the last decade while disquieting decreases have been noticed of the natural populations. In line with the expand evaluations of microbial dietary supplements and prebiotics in finfish and shellfish aquaculture, the scientific community has also increased their interest in approaches to these issues in sturgeon aquaculture. The present review summarizes and discusses the results on intestinal microbiota of sturgeon species and the effects of probiotic, prebiotic or synbiotic administration on growth performance, gut physiology, intestinal microbiota, immune response and health. Furthermore, this study tries to cover the gaps of existing knowledge and suggest issues that merits further investigations.
