Lu, Yuting published the artcileComparison of gut microbial communities, free amino acids or fatty acids contents in the muscle of wild Aristichthys nobilis from Xinlicheng reservoir and Chagan lake, Application of (S)-2-Amino-4-(methylthio)butanoic acid, the publication is BMC Microbiology (2022), 22(1), 32, database is CAplus and MEDLINE.
Fish is favored by consumers, while amino acids and fatty acids are the main nutrients of muscle. At present, it has been found that the gut microbial community may be involved in the regulation of host material anabolism. Juvenile and adult bighead carp (A. nobilis) from Chagan lake and Xinlicheng reservoir were selected, and divided into four groups to compare the differences of gut microbial communities, free amino acid and fatty acids in muscle. The results showed that fish in different lakes or ages contained specific microbiota, the gut microbial structure was similar, but the microbial content was significantly different. Gut microbial abundance of juvenile fish in Chagan lake was significantly higher than that of other groups. Phylum level anal. Proteobacteria was the dominant gut bacteria of fish in both adult and juvenile fish from two sep. lakes. Actinobacteria was another dominant bacterial phylum in juvenile fish in both lakes. Contents of free amino acids and fatty acids in muscle were detected, and the relationships between them and gut microbial communities were analyzed. Bighead carp grew from juvenile to adult, Actinobacteria abundance decreased (P < 0.05) and Proteobacteria increased (P < 0.05). Proteobacteria was pos. correlated with the contents of Thr, Lys, Pro, Asp, Gly and Glu, Actinobacteria was neg. correlated with Met and His. Meanwhile, EPA and DHA were pos. correlated with Proteobacteria, EPA and DHA were not significantly associated with Actinobacteria. It was speculated that the contents of free amino acids and fatty acids in muscle might be affected by the difference of gut microbiota, thus affecting the taste and nutritional quality.
