The subject invention provides materials and methods for producing, isolating, extracting and purifying single-molecule products. The subject invention provides materials and methods for extracting microbial metabolites at a high level of purity, for example, a purity of at least 80% by weight, and preferably at least 95% by weight or more. Specifically, the subject invention provides materials and methods for isolating or extracting biosurfactants and polyketides at a high level of purity. Preferably, the biosurfactant is a sophorolipid (SLP).

Disclosed herein is a process for producing a peanut milk product, which includes subjecting a milk material to a hydrolysis reaction with lactase and transglucosidase to obtain a milk product, immersing peanut kernels in water to obtain swelled peanut kernels, subjecting the swelled peanut kernels to a steam cooking treatment to obtain steamed peanut kernels, and admixing the milk product with the steamed peanut kernels, followed by subjecting a mixture thus obtained to a heating treatment, so as to obtain the peanut milk product. A method for improving gut health using the peanut milk product and a canned food containing the peanut milk product are also disclosed.

A material with a scaffold comprising a series of at least partially spaced fibers and gas vesicles locates between fibers. The gas vesicles comprise external anchoring modules that are effective to anchor the gas vesicles to the fibers.

The invention discloses a recombinant Corynebacterium glutamicum for efficient synthesis of highly pure hyaluronic acid and oligosaccharides thereof, belonging to the technical field of bioengineering. The recombinant Corynebacterium glutamicum constructed in the present invention can produce hyaluronic acid with a yield up to 40g/L, and a crude product purity of 95%. Addition of exogenous hyaluronic acid hydrolase and optimization of the fermentation conditions results in hyaluronic acid oligosaccharides with specific molecular weight, and can further improve the yield of hyaluronic acid to 72 g/L. The invention lays a solid foundation for the efficient synthesis of highly pure hyaluronic acid by microorganisms, and the constructed recombinant Corynebacterium glutamicum is suitable for industrial production and application.
