Optimization of the fermentation process of Moutai-flavored with the addition of green tea: impacts on bacterial succession and endogenous factors.

Unlabelled: This study explored the impact of green tea addition on bacterial communities in Moutai-flavored fermentation using high-throughput sequencing, alongside physicochemical and flavor analysis. Significant differences in microbial succession were observed over the 40-day fermentation period among types with varying tea proportions, resulting in distinct bacterial communities. Sixteen dominant genera, including , , and , were identified, with their relative abundances and succession patterns varying by type.

The spatio-temporal diversity and succession of microbial community and its environment driving factors during stacking fermentation of Maotai-flavor baijiu.

Stacking fermentation is an important stage of microbial expansion and enrichment in the brewing process of Maotai-flavor baijiu and has an important impact on quality. However, the structure and succession of microbial communities at different spatial points of fermented grains, as well as the key environmental factors driving community assembly, remain unclear. Here, we analyzed spatio-temporal similarities and differences in the microbial community structure and succession during 1-6 rounds of stacking fermentation of Maotai-flavor baijiu.

High magneto-optical characteristics of Holmium-doped terbium gallium garnet crystal.

Magneto-optical characteristics of a new magneto-active material, (TbHo)GaO crystal, have been grown by the Czochralski (Cz) method. A high value of the Verdet constant was obtained at room temperature-namely, 214.9 and 77.

Assessment of dietary intake of polychlorinated dibenzo-p-dioxins and dibenzofurans and dioxin-like polychlorinated biphenyls from the Chinese Total Diet Study in 2011.

The concentrations of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) as well as dioxin-like polychlorinated biphenyls (dl-PCBs) were measured in food samples from the fifth Chinese Total Diet Study (TDS) performed in 2011. A total of 152 composite samples from various food groups were analyzed by high resolution gas chromatography-high resolution mass spectrometer (HRGC-HRMS). The dietary intakes of PCDD/Fs and dl-PCBs were subsequently estimated for the adult from various regions in China.

Fabrication and characterization of cerium-doped terbium gallium garnet with high magneto-optical properties.

High optical quality (Tb((1-x))Ce(x))₃Ga₅O₁₂ (TCGG) single crystal has been grown by the Czochralski method. The optical and magneto-optical properties of the TCGG are analyzed in detail and the Verdet constant (V) of TCGG is compared with that of undoped terbium gallium garnet (TGG) crystal. TCGG presents a very high transmittance, particularly in the visible-near infrared (VIS-NIR) region, and its V is obviously larger than that of TGG in the VIS-NIR region.

Assessment on dioxin-like compounds intake from various marine fish from Zhoushan Fishery, China.

Sea fish consuming is an important intake source of dioxin-like compounds, especially for the coastal residents. To assess the intake levels of these contaminants from sea fish and to provide risk-based consumption advice, concentrations of 17 polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and 12 dioxin-like polychlorinated biphenyls (dl-PCBs) were measured in 32 commonly consumed fish species from Zhoushan Fishery, China. Due to the different accumulation influenced by fat content, feed habits and living zone in the sea area, the levels of PCDDs, PCDFs and dl-PCBs in different fish species varied significantly ranging from 0.
