“…New research has suggested that changes in the intestinal flora of fish are correlated with changes in their muscle nutrition. 33,34 Through functional prediction analysis of PICRUSt2, we found that the secondary functional layer of intestinal bacterial genes mainly included amino acid and fatty acid metabolism in the rice-fish symbiosis of tilapia. Our research showed that the superpathways of chorismate metabolism, the superpathways of L-phenylalanine biosynthesis, the superpathway of L-tyrosine biosynthesis, the superpathway of L-aspartate and L-asparagine biosynthesis, the aspartate superpathways, the L-lysine biosynthesis II, the β-alanine biosynthesis II, the fatty acid β-oxidation I, and the superpathways of fatty acid biosynthesis initiation (E. coli) in the gut of tilapia in the R group had a higher number of predicted genes than T group.…”

Rice-fish symbiosis is an ecological farming model that can improve fish’s muscle nutrient profile and intestinal flora. We investigated the effect of rice-fish symbiosis on tilapia’s intestinal flora and muscle nutrients. We used 16S rDNA technology to analyze the intestinal flora of tilapia in pond culture and rice-fish symbiosis. Furthermore, spearman correlation analysis was performed on tilapia intestinal flora and muscle nutrients. The results showed that the contents of Valine, Phenylalanine, and Docosahexaenoic acid were significantly higher in the rice-fish symbiosis than those in the pond culture (p<0.05). Intestinal flora analysis showed that the diversity in rice-fish symbiosis was significantly higher than in pond culture (p<0.05). Meanwhile, the abundance of Brevundimonas, Pseudomonas, and Ralstonia in rice-fish symbiosis was significantly higher than those in pond culture (p<0.05), but Pirellulaceae unclassified and Cyanobium_PCC-6307 were opposite. The number of 8 predictive functional tilapia genes in the rice-fish symbiosis was higher than in the pond culture. Correlation analysis showed that the abundance of Ralstonia was positively correlated with the contents of Valine, Phenylalanine, and Docosahexaenoic acid, respectively. Our study shows that the rice-fish symbiosis could improve muscle nutrient profile and intestinal flora diversity in tilapia. This study will help to improve the rice-fish symbiosis model and provide a scientific basis for ecological aquaculture and healthy fish production.

ScopeButyric acid (C4) and lauric acid (C12) are recognized as functional fatty acids, while the health benefits of the structural lipids they constitute remain unclear.Methods and resultsIn this study, lauric acid‐butyric structural lipid (SLBL) is synthesized through ultrasound‐assisted enzyme‐catalyzed acidolysis and its health benefits are evaluated in a high‐fat diet‐induced obesity mouse model. SLBL and its physical mixture (MLBL) do not significantly inhibit obesity in mice. However, SLBL treatment increases the ratio of n3/n6 fatty acids in the liver and improves obesity‐induced hepatic lipid metabolism disorders. Furthermore, the expression of liver pro‐inflammatory cytokines (interleukin [IL]‐6, IL‐1β, TNF‐α) are significantly suppressed by SLBL, while the expression of anti‐inflammatory cytokine (IL‐10) is increased. Moreover, SLBL ameliorates the dysbiosis of small intestinal microbes induced by high‐fat diet and regulates microbial community structure to be close to the control group. Especially, SLBL significantly alleviates the high‐fat diet‐induced decrease in Dubosiella and Bifidobacterium abundance. Correlation analysis reveals that SLBL treatment increases the abundance of microorganisms with potential anti‐inflammatory function and decreases the abundance of potentially pathogenic bacteria.ConclusionIn all, small intestinal microbes may be a significant bridge for the positive anti‐inflammatory effects of SLBL, while the exact mechanism remains to be clarified.
