The invention discloses a preparation method of natural lemon liquid fermented fruit vinegar. The preparation method comprises the steps: picking up lemon fruits, juicing, adjusting the sugar content, heating, insulating heat and cooling; mixing wine yeast, saccharomyces cerevisiae and streptococcus pasteurianus to obtain a mixed strain; transferring the lemon juice to the mixed strain, and fermenting to obtain a fermentation liquid; mixing acetobacter pasteurianus, gluconacetobacter xylinus and glucinacetobacter hansenii to obtain mixed acetic acid bacteria; transferring the fermentation liquid to the mixed acetic acid bacteria and fermenting to obtain lemon fermented vinegar; adding chitosan to the lemon fermented vinegar, clarifying, and sterilizing to obtain the natural lemon liquid fermented fruit vinegar. The acid components of the product are capable of dredging and softening blood vessels, killing bacteria, enhancing human immunity and virus resisting capability, improving digestion system, and cleaning digestive tracts, and have obvious blood fat reducing and health preserving functions; the natural lemon liquid fermented fruit vinegar is high in alcohol and acetic acid content, high in fermentation speed and good in flavor, has special fruit flavor of lemons and also has special flavor of lemon juice fermented fruit vinegar.

The invention belongs to the field of biological materials, and in particular relates to a simple and fast method for producing PHB / bacterial cellulose composite materials, comprising: 1) cultivation of Ralstonia eutropha bacterial liquid; 2) cultivation of Gluconacetobacter xylinus bacterial liquid: 3) taking Ralstonia eutropha bacteria The solution is added to the basic culture solution containing Gluconacetobacter xylinus cells, dynamic culture and static culture are carried out, the bacteria solution is collected, and the bacterial cellulose / PHB composite product is extracted. The method of the invention can produce the required composite material by directly adding an appropriate amount of Ralstonia eutropha bacterial liquid in the cultivation process of Gluconacetobacter xylinus, and the method has the advantages of simple operation, low cost, mild condition, environment friendly and the like.

The invention discloses monascus-nata complex and a preparation method thereof. The monascus-nata complex is prepared by inoculating gluconacetobacter xylinus seed liquid and red kojic rice into a coconut water culture medium for fermentation, wherein the gluconacetobacter xylinus seed liquid is prepared by adding sucrose, (NH4)2SO4, KH2PO4, MgSO4 and yeast extract into coconut water, and taking gluconacetobacter xylinus as a strain; and the red kojic rice is prepared by soaking and steaming long shaped rice, inoculating amaranthine aspergillus for fermentation, drying and crushing. The invention combines various health care functions of high-fiber nata de coco and red yeast rice together, is beneficial to promoting the development of the nata de coco processing industry and has importantapplication values in the aspects of economic benefits, social benefits, and the like.
