Article Abstract
In the present study, four species that could degrade Fuzhuan brick tea polysaccharide-3 (FBTPS-3) were isolated from human feces and identified to be , . The four species showed growth on FBTPS-3 as the carbon source, and showed the best capability for utilizing FBTPS-3 among the four species since could utilize more FBTPS-3 during 24 h fermentation. Moreover, the four species could metabolize FBTPS-3 and promote the production of acetic, propionic and isovaleric acids. Transcriptome analysis of revealed that 602 genes were up-regulated by FBTPS-3, including two carbohydrate-active enzyme clusters and four polysaccharide utilization loci (PULs). The PUL 1 contained GH28 family that could hydrolyze rhamnogalacturonan and other pectic substrates, which was in line with our previous work that rhamnose and galacturonic acid were the main component monosaccharides of FBTPS-3. Collectively, the results suggested that FBTPS-3 could be utilized by spp., and it might be developed as a promising prebiotic targeting Bacteroidetes in intestinal environment.

In this study, the chemical constituents, quality and functional characteristics of the mixture of Fuzhuan brick tea and wheat bread (2:100, 4:100, 6:100, 8:100, 10:100) were investigated to guide the production of slow-digested wheat bread. The dough fermentability, the content of free sulfhydryl groups and wet gluten, specific volume, sensory evaluation were determined to evaluate the influence of Fuzhuan brick tea on wheat bread quality. When the ratio of tea to water was 6:100, the dough fermented faster, and the resulting bread, with the flavor of Fuzhuan brick tea, was of higher quality and more acceptable to consumers.

(EC), the dominant fungus in Fuzhuan brick tea, has significant applications in food fermentation and pharmaceutical industries, exhibiting probiotic properties, but further investigation of its intestinal benefits is required. This study characterized the EC-520 strain through whole genome sequencing and evaluated its effects on rat colons using histomorphology, 16S rRNA sequencing, and untargeted metabolomics. The genomic analysis revealed that EC-520 possessed a 28.

Probiotics are considered an effective strategy for relieving DSS-induced colitis. This study investigated the protective effects and mechanisms of , a potential probiotic fungus from Fuzhuan brick tea, on colitis. Supplementation with live 10 spores/mL of H-1 and 10 spores/mL of S-6 significantly improved gut integrity by preventing colon shortening, mucus disruption, and goblet cell depletion.

Drinking tea is beneficial to reduce the incidence of obesity. Unlike Fuzhuan brick tea (DT, a typical dark tea) widely reported to have good glycolipid-lowering activity (GLA), there is little information on GLA of Dancong summer tea (OT, a typical oolong tea). A comparative study on GLA and chemical compositions of OT and DT was systematically conducted.
