Abstract: As a probiotic,Rhodopseudomonas palustris is not only metabolically robust but also rich in a variety of amino acids,vitamins,carotenoids,coenzyme Q,and other bioactive substances.It exhibits numerous biological functions.On the one hand,Rhodopseudomonas palustris can purify water by degrading and assimilating nitrogen,phosphorus,and other compounds through the production of specific metabolic enzymes.On the other hand,it promotes the growth of aquatic animals by providing essential nutrients,enhancing digestive enzyme activities,and increasing the abundance of beneficial intestinal bacteria.Moreover, Rhodopseudomonas palustris boosts the disease resistance of aquatic animals by enhancing the activity of immune-related enzymes to strengthen non-specific immunity,modulating signaling pathways to activate specific immunity,and producing antimicrobial substances or competing for ecological niches to inhibit the growth of pathogenic bacteria.Given the context of intensive aquaculture practices and the feed additive restrictions,Rhodopseudomonas palustris is widely utilized in aquaculture as a water purifier and feed additive due to its critical functions of improving water quality,enhancing animal growth performance,and strengthening immunity.The authors systematically reviewed the research progress on Rhodopseudomonas palustris in aquaculture,offering insights into future research directions and serving as a reference for further studies on its application in this field.
