Abstract: The invention provides a microbial composition with weight loss efficacy, the microbial composition including Lactobacillus gasseri and Akkermansia muciniphila; a ratio of the Lactobacillus gasseri and the Akkermansia muciniphila is 2:3-3:2 by viable counts. By probiotic composition containing a specific proportion and content of Lactobacillus gasseri and Akkermansia muciniphila, it is able to improve body weight abnormalities caused by metabolic diseases.

Abstract: This application provides an information processing method and apparatus, an electronic device, a computer program product, and a non-transitory computer-readable storage medium. The method includes: obtaining an information stream and a promotion video in response to a user trigger operation, the information stream including at least one piece of media information and the promotion video including at least one material to be recommended; and displaying, at a first area of an information stream interface, a first part of the promotion video in a presentation mode and displaying, at a second area of the information stream interface, a second part of the promotion video in a transparent mode, so as to enable the information stream interface to be revealed through the second area, the first area and the second area being dynamically changing areas.

Abstract: Disclosed are an oil-in-water (O/W) emulsion gel and a preparation method and use thereof, and a fat substitute. The O/W emulsion gel includes: starch nanoparticles with a content of 8 g/L to 40 g/L, curdlan with a content of 10 g/L to 30 g/L, an oil with a volume fraction of 10% to 30%, and water. The O/W emulsion gel could be used to prepare a fat substitute, especially the fat substitute prepared by 3D printing with various complex models.

Abstract: The present disclosure discloses a preparation method of porous starch for encapsulating probiotic, and belongs to the field of food processing. The present disclosure provides porous starch with controllable pore size and morphology by regulating the ratio of amylose to amylopectin (quantitative compounding), keeping starch hydroxyl sites exposed (concentration cultivation), and building interfacial tension to stretch starch chains (convection drying), and uses the porous starch to encapsulate probiotics, which can improve the retention rate of probiotics, reduce the loss of probiotics during food processing and transportation, and thus retain the biological functions of probiotics to a maximum extent.

Abstract: A lithium metal negative electrode includes a substrate, lithium metal, and a fiber layer. The substrate includes a copper mesh. The copper mesh is plated with the lithium metal. The copper mesh and the fiber layer are composited. The copper mesh serves as a substrate support structure for supporting the lithium metal.

Abstract: Disclosed in the present invention is a system and method for supplying acetylene to an apparatus using acetylene, the system having at least one acetylene storage apparatus and an acetylene content analysis apparatus. The system and method disclosed in the present invention can utilize the capacity of an acetylene cylinder to a higher degree; before the solvent impurity concentration in acetylene gas reaches a level where it is no longer suitable, a more accurate understanding of the usable acetylene amount in the acetylene storage apparatus can be gained through detection, thereby reducing the number of times that the acetylene storage apparatus is refilled and replaced, and lowering the user's total costs.
