Bifidobacteriumlongumsubsp. infantis (***. infantis) and Bifidobacteriumadolescentis(B. adolescentis) play important roles in the guts of infants and adolescents， respectively. In this study， using a neonatal rat model， we compared the protective effects of these two bifidobacterial species against Salmonella infection. The results demonstrated that ***. infantis was more effective than B. adolescentis in alleviating the severity of infection in newborn rats exposed to Salmonella entericaserovarTyphimurium strain SL1344. B. *** attenuated intestinal inflammation and mucosal damage induced by Salmonella infection， as well as protecting intestinal nerves and intestinal barrier function through TLR4/MyD88 signalling. B. longumsubsp. infantis also displayed the potential to modulate gut metabolites by promoting the biosynthesis of unsaturated fatty acids (arachidonic acid， eicosapentaenoic acid and α-linolenic acid) and purine metabolism (guanine， adenine， inosine and adenosine)， thereby regulating metabolic disturbances. Additionally， the benefits of B. *** were also observed in the liver， spleen and brain， improving nerve reflexes and suppressing hepatosplenomegaly. Overall， these findings provide novel insights into the prevention and treatment of gut-related diseases in newborns， highlighting the potentially significant role of B. *** in clinical applications.

The inflammatory response is a crucial physiological process that can lead to tissue damage and is considered a causative factor for various chronic diseases， such as rheumatoid arthritis. Recent research has focused on exploring valuable nutrients derived from Cannabis sativa L. (hemp) seeds， particularly hemp seed proteins. Therefore， this study aimed to investigate the release of anti-inflammatory peptides from Lactobacillus paraplantarum-fermented hemp seed proteins. To confirm the complete hydrolysis of hemp seed proteins during the fermentation process， SDS-PAGE was employed. Further， the isolation and purification of peptides were achieved through ultrafiltration. The identity of peptides was nextly established using ultra-high-performance liquid chromatography coupled with hybrid quadrupole time-of-flight mass spectrometry (UHPLC-QTOF-MS). The results revealed a total of 39 identified peptides in fermented hemp seeds， with 9 peptides selected based on their relative quantity. Notably， AAELIGVP (P1)， AAVPYPQ (P2)， VFPEVAP (P4)， DVIGVPLG (P6)， and PVPKVL (P9) demonstrated strong anti-inflammatory abilities in LPS-induced Raw 264.7 macrophage cells. Molecular docking was used to understand the potential anti-inflammatory mechanism of these five peptides， and in silico results indicated that P1， P2， P4， P6， and P9 could bind to the active sites of TLR-4， NF-kB， and IKK with higher binding energies. Overall， these findings indicate that hemp seeds have potential to be a source of bioactive peptides for functional foods with anti-inflammatory properties.

This study was performed to investigate the changes in microbial communities and metabolites during the long-term fermentation of commercially manufactured anchovy sauce. Samples of commercial anchovy sauce were collected from large-scale fermentation tanks with fermentation periods of up to 7.87 years. The complex bacterial community was simplified to two genera， Tetragenococcus and Halanaerobium， after approximately 0.55 years of fermentation. Although genera， such as Saccharomyces， Cladosporium， Candida， and Aspergillus， were relatively dominant， no clear pattern was identified in fungal community analysis. The longitudinal metabolite profile demonstrated that approximately half (55.8%) of the metabolites present in anchovy sauce were produced within a year of fermentation due to rapid fermentation. Despite the static microbial community， the contents of several metabolites including amino acids and biogenic amines changed continuously during the long-term fermentation of anchovy sauce. This study provides novel insights into the changes in microbiota and metabolites in fish sauce produced without any starter inoculation.
