The present invention relates to a ready to drink beverage composition comprising fermented hemp or fermented hemp extract. A further aspect of the invention is a method of preparing a ready to drink beverage composition.

Disclosed is a method for collecting bacteria from bacterial or fungal fermentation culture broth, the method comprising the steps of: a) mixing bacterial or fungal fermentation culture medium with a carboxylated chitosan to obtain a mixture; optionally, b) adding a sodium alginate solution to the mixture and mixing homogeneously; and c) precipitating to obtain bacterial or fungal cell precipitate or culture supernatant.

A recombinant type I allergen of Artemisia vulgaris pollen (Art v 1), a coding gene, an expression method, and a purification method thereof are provided. By different combinations of codon optimization, different signal peptides, expression vectors and strains, the Art v 1 obtained reaches the expression level of more than 200 mg/L, with a purity of more than 99%, and the activity of the Art v 1 is equivalent to that of a native protein, and the Art v 1 can be used for the desensitization immunotherapy and diagnosis of Artemisia pollen allergy.

The present invention relates to a beverage composition comprising fermented camomile or fermented camomile extract. A further aspect of the invention is a method of preparing a beverage composition.

Provided in the present disclosure are a yeast protein having an antibacterial function and a preparation method therefor. The method includes: S1, performing liquid fermentation on a Saccharomyces cerevisiae strain, and then performing separation to obtain a yeast milk; S2, acidifying the yeast milk to obtain an acidified yeast milk; and optionally performing autolysis, or exogenous enzyme catalytic hydrolysis, or mechanical crushing on the yeast milk to obtain a cell wall emulsion; S3, mixing the acidified yeast milk and the optional cell wall emulsion and performing autolysis to obtain an autolysis mixed solution; S4, performing first enzymolysis with compound protease; S5, performing second enzymolysis with seminase; and performing third enzymolysis with -glucanase and cellulase to obtain a yeast protein emulsion; and S6, evaporating and concentrating the yeast protein emulsion to obtain the yeast protein. According to the method, a yeast protein having a broad-spectrum antibacterial function can be prepared.

The present invention relates to fungal cells, in particular methylotrophic fungal cells, for use in improved production of recombinant peptides of interest and processes for producing recombinant peptides of interest.

The present invention relates to a beverage composition comprising fermented verbena or fermented verbena extract. A further aspect of the invention is a method of preparing a beverage composition.

A recombinant alphal-antitrysin (AAT) protein or a fragment thereof expressed in a genetically modified yeast for use in the treatment of a viral infection and/or lung inflammation. In one embodiment, the viral infection is a viral respiratory infection, preferably a coronavirus infection, such as a SARS CoV infection, more preferably SARS-CoV-2. Also disclosed is a method of producing recombinant AAT protein or fragment(s) thereof from genetically modified yeast. In embodiments, the method includes the steps of culturing a genetically modified yeast comprising an exogenous nucleic acid molecule with an AAT-encoding region operably linked to a promoter or promoter/enhancer combination, expressing recombinant AAT in the cultured yeast, and isolating recombinant AAT from the culture. In embodiments, the recombinant AAT produced from yeast is prepared in a pharmaceutical composition, such as a solution, preferably suitable for nebulization and subsequent inhalation by a subject.
