To obtain protease- and lipase-producing halotolerant/halophilic strains suitable for shrimp paste (SP) fermentation， the microbial community structure and enzyme-producing microbial species were analyzed and predicted using metagenomics in three high-salt samples. Based on the linear salt gradient method， 128 strains were screened. Eight halotolerant/halophilic strains highly producing two types of enzymes were identified and inoculated into low-salt SP to assess the heterogeneity of SP. Physicochemical properties of SP indicated that Bacillus subtilis XJ-11， Virgibacillus halodenitrificans XJ-229， Piscibacillus halophilus XY-193， and Bacillus vallismortis HT-73 were more suitable for rapid fermentation of SP. Nutritional analysis showed that SP inoculated with V. halodenitrificans XJ-229 had the highest free amino acid content and SP inoculated with P. halophilus XY-193 had the highest unsaturated fatty acid content. The former had prominent umami， sweetness， and meaty aroma， weak bitterness and fishy flavor， and the closest flavor to the control based on sensory evaluation and E-nose analysis. A total of 61 volatile compounds were detected in all samples by SPME-GC-MS， of which 32， 23， 40， 24， and 28 were detected in the control and SP inoculated with B. subtilis XJ-11， V. halodenitrificans XJ-229， P. halophilus XY-193， and B. vallismortis HT-73， respectively， with 12， 11， 12， 9， and 9 key flavor compounds. Among several samples， the highest levels of pyrazines， aldehydes， alcohols， and ketones were found in SP inoculated with B. subtilis XJ-11， V. halodenitrificans XJ-229， P. halophilus XY-193， and B. vallismortis HT-73， respectively. These results suggested that inoculation of different enzyme-producing halotolerant/halophilic strains resulted in differences in SP quality and main flavors. This study provides some references for process control and interpretation of heterogeneous mechanisms in low-salt SP fermented by inoculated strains.

Obesity has brought great challenges to global human health， and how to effectively prevent and control the occurrence and development of obesity has become an urgent problem. The role and mechanism of 4-[(α-L-Rhamnosyloxy) benzyl] isothiocyanate (MITC)， an active ingredient of Moringa oleifera Lam.， in the regulation of lipid metabolism have not been comprehensively investigated. In the present study， we investigated the mechanism of MITC in inhibiting lipid accumulation in mice fed with a high-fat diet (HFD) in terms of both lipolysis and central appetite regulation mediated by the gut microbe–gut–brain axis. MITC enhanced the characteristic indices associated with HFD mice and also promoted adipocytolysis and brown fat thermogenesis. Moreover， MITC was observed to improve leptin resistance， modulate the composition of gut microbiota such as Ruminococcaceae， Parasutterella， and Acetatifactor， promote 5-HT secretion， further enhance the secretion of glucagon-like peptide-1 (GLP-1) and peptide tyrosine-tyrosine (PYY) to activate peroxisome proliferator-activated receptor (PPAR) signaling in the hypothalamus， and modulate feeding behavior to inhibit lipid accumulation in HFD mice. These data suggest that MITC supplementation can help to alleviate obesity or obesity-related diseases.
