Probiotic Effects of a Marine Purple Non-Sulfur Bacterium, Rhodovulum sulfidophilum KKMI01, on Kuruma Shrimp (Marsupenaeus japonicus)

Abstract: Purple non-sulfur bacteria (PNSB) are used as probiotics in shrimp aquaculture; however, no studies have examined the probiotic effects of PNSB in shrimp at the gene expression level. In this study, we examined the effects of a marine PNSB, Rhodovulum sulfidophilum KKMI01, on the gene expression of kuruma shrimp (Marsupenaeus japonicus). Short-term (3 days) effects of R. sulfidophilum KKMI01 on the gene expression in shrimp were examined using small-scale laboratory aquaria experiments, while long-term (145 da… Show more

“…Vertical transmission of specific bacterial taxa from parents to their offspring has also been demonstrated in Rimicaris exoculta , a shrimp species living in hydrothermal vent areas [ 50 , 51 ], as well as in other marine hydrothermal or cold seep organisms such as clams [ 52 ] and aquatic macroorganisms such as fish or sponges [ 53 , 54 ]. Among the core microbiota, several lineages such as Alteromonas , Ascidiaceihabitans (formerly Roseobacter ), Halomonas , Litoricola , Leisingera , Micrococcus , Pseudoaltermonas , Rhodovulum , Ruegeria and Sulfitobacter might exhibit probiotic or beneficial activities [ 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 ]. Others have a putative antimicrobial activity or ixotrophic activity with evidence of ASV related to Aureispira or the OM27 Clade ( Bdellovibrionaceae, affiliated with the Bdellovibrio and like organisms) [ 6 , 65 ].…”

“…In general, Lactobacillus and Rhodovulum are probiotics that are colonized within the digestive tracts and are equipped with anti-microbial properties that inhibit the growth of pathogenic bacteria such as Vibrio sp. in fish and shrimp (Slover and Danziger, 2008;Liu et al, 2013;Chang et al, 2019;Koga et al, 2022). On the other hand, Shimia, Reugeria and Pseudoruegeria are beneficial bacteria with metabolic capability that could synthesize various bioactive molecules which are involved in the host adaptation and defence mechanism (Kanukollu et al, 2016;Abisado et al, 2018;Cho et al, 2020).…”

“…They also engage in the blockage of the pathogen's ability to utilize certain nutrients, prevention of their attachment to the host environment, distortion of the enzymatic activities of the pathogens, enhancement of the quality of water, stimulation of the immune system, and improvement of host nutrition. Marine probiotics are a promising source of novel bioactive compounds with anticancer, antibacterial, immunomodulatory, antioxidant, anti-inflammatory, and antiviral properties, as have been implicated in several studies [27,[32][33][34][35][36][37][38][39].…”
