The invention discloses rhodotorula glutinis Harrison OMK-1 and method for fermentation production of natural cinnamic acid by virtue of the rhodotorula glutinis Harrison OMK-1, wherein the rhodotorula glutinis Harrison OMK-1 is rhodotorula sp. OMK-1 and is used for producing natural cinnamic acid. The production method of the natural cinnamic acid is achieved through fermentation by virtue of the rhodotorula sp. OMK-1. The fermentation method comprises steps of strain activating, seed culturing, fermenting, extracting and the like. The production method disclosed by the invention is a method which produces the natural cinnamic acid from glucose, amino acid and like natural raw materials by virtue of a microorganism fermentation method and produces a target product through microorganism metabolism; and the process, which belongs to the technical field of low temperature and low pressure, is relatively safe, simple in operation and small in pollution, and is a safe and environment-friendly production method.

The invention relates to crack self-repairing concrete using aerobic basophilic microorganisms and a preparation method thereof. The concrete contains expanded perlite loading an aerobic basophilic microorganism repair agent, cement, pebbles, sand, silica fume, water, calcium lactate and water reducer. The crack self-repairing concrete has the crack self-repairing function and has heat-preservation and heat-insulation functions, the aerobic basophilic microorganisms serve as a crack repairing agent, calcium lactate serves as nutritional matter for microorganism metabolism, and expanded perlite serves as a carrier of the crack repairing agent. When concrete cracks, water and air enters the cracks so that resting microorganisms can restore the metabolism function, calcium lactate is converted into calcium carbonate precipitate, and accordingly the aims of automatically diagnosing and repairing the concrete cracks, preventing expansion of the cracks and improving concrete impermeability are achieved. The microorganism crack self-repairing concrete serves as a concrete material integrating the functions of crack self-diagnosis and self-repairing, lightweight, heat preservation and heat insulation, and has large research value and application potential.

The invention provides a manufacturing method for a sprouted brown rice beverage, belongs to the technical field of beverage processing, and particularly relates to the manufacturing method for the sprouted brown rice beverage. The method comprises the following steps: using the sprouted brown rice as a raw material, preparing a fermentation fluid through the working procedures of microzyme fermentation, ethyl alcohol leaching, acetic acid bacteria fermentation and the like, and then obtaining finished products by diluting, mixing, filtering, bottling and disinfecting the fermentation fluid. The sprouted brown rice beverage disclosed by the invention overcomes the defect that the mouth feel of the brown rice is not good. Through the effect of the fermentation, macromolecular substances in the brown rice are degraded into micromolecule substances which are easily digested and absorbed by human bodies; at the same time, a large number of microorganism metabolism products which are beneficial to the human bodies are produced; at the same time, through the soaking effect of acetic acids, many nutrient substances in the brown rice, which are insoluble in water, are lixiviated; and therefore, the sprouted brown rice beverage disclosed by the invention remains the original nutrient components of the sprouted brown rice, at the same time, the sprouted brown rice beverage is easier to absorb, the mouth feel of the sprouted brown rice beverage is better, and the efficacies of the sprouted brown rice beverage are more outstanding.

The invention discloses a fermented biological feed prepared from the red date leftovers and a preparation method thereof, and belongs to the technical field of biological feed. The preparation method comprises the following steps: taking red date leftovers, rice bran, corn bran, and soybean meal as the mixed material, and ammonium chloride, magnesium sulfate, and potassium dihydrogen phosphate as the addictive; activating mixed bacterium liquid in a water solution containing the addictive; and then adding the activated mixed bacterium liquid into the mixed material to carry out fermentation reactions so as to obtain the fermented biological feed. The preparation method comprises the following processes: (1) material mixing; (2) bacterium liquid activation; (3) fermentation. Through the microorganism metabolism, the coarse fiber content is reduced, the species and number of amino acid are increased; the feed palatability is improved, the feed intake of the feeding objects is effectively promoted, the growth of the feeding objects is promoted, the marketing period is shortened, and the profit is raised.
