  • Publication number: 20240182847
    Abstract: A strain of Bifidobacterium longum subsp. infantis Y46 with fimbriae (BI_Y46) includes a unique flagella structure, exhibits strong abilities in utilizing 2-fucosyllactose (2?-FL), galacto-oligosaccharides and short-chain galacto-oligosaccharides, possesses excellent probiotic characteristics with higher levels of extracellular polysaccharides and surface proteins than a strain of Bifidobacterium longum subsp. infantis M63 (BI_M63) and a strain of Bifidobacterium longum subsp. infantis ATCC 15697 (BI_15697), and further displays stronger ability to tolerate gastric acid and inhibitory ability of the cell-free supernatant to Escherichia coli ATCC 15922 than the BI_15697. Therefore, the BI_Y46 has excellent probiotic potential and can be used to develop probiotics, infant food, prebiotic products, and functional foods.

  • Patent number: 10479694
    Abstract: The present disclosure provides a process of clean production of electronic grade high-purity copper oxide. The process includes (1) preparing a carbon-ammonia system solution with a certain ratio of CO2, NH3 and H2O; (2) dissolving copper under a slightly negative pressure and at a system temperature less than or equal to 60° C.; the reaction ends until the concentration of copper in the carbon-ammonia system solution reaches 80 to 140 g/L; (3) adding sodium polyacrylate; the reaction solution is heated to 60-80° C. under a reduced pressure for deamination; (4) disposing basic copper carbonate to separate the solid from the liquid by a centrifuge to give an filter cake and copper-containing clear solution; (5) calcining the filter cake at 250-600° C.
