The invention discloses a strain of bacillus for highly efficient anaerobic reduction of arsenic. The bacillus is preserved in China Center for Type Culture Collection, and the preservation number is CCTCC NO: M2018411. Under anaerobic culture conditions, Bacillus has high arsenic reducing ability, and the arsenic reducing rate reaches more than 80% in 4 days, which is of great significance for studying the migration and transformation of arsenic.

The invention relates to an extract derived from animal tissue, a preparation method and application thereof. The method comprises the following steps: (1) homogenizing the animal tissue; (2) adding a low-concentration aqueous solution of trypsin to the homogenized tissue obtained in step (1) to prepare a mixed solution, without adding any medium Place it in an anaerobic incubator and incubate; (3) centrifuge the mixture after incubation in step (2), collect the supernatant while retaining the deposited tissue; (4) obtain the deposited tissue in step (3) Add a high-concentration trypsin aqueous solution to the substance, then stir, centrifuge, and collect the supernatant; (5) combine the supernatant collected in step (3) and step (4). The method of the invention can prepare the extract with high extraction rate, and the obtained extract has stable performance.

The invention belongs to the technical field of food processing, and relates to a dietary supplement rich in soybean polypeptide and a preparation method thereof. The method comprises the following steps: A. preparing a fermentation base material, dissolving soybean polypeptide in water, adding sugar, homogenizing to obtain a homogenate liquid, cooling after sterilization, B. preparing a mother starter, taking a dairy solution, cooling after sterilization, and putting it in the dairy solution Add compound lactic acid bacteria suspension, anaerobic culture to obtain the mother starter, C, prepare fermentation broth, put the fermentation base material under sterile conditions, adjust the temperature to 35-42°C, then add an appropriate amount of mother starter, and cultivate for 3-6 Hours, D, hydrolyzed, the temperature of the fermented liquid is raised to 45-55°C, hydrolyzed at 45-55°C to obtain a hydrolyzed liquid, E, dried, an appropriate amount of cyclodextrin is added to the hydrolyzed liquid, dried to remove moisture, and dried powder. The invention has rich nutrition, good taste and is easy to be absorbed by human body.

The invention discloses a floating type double-bed micro-porous membrane water body repairing device which comprises a floating plate, a photovoltaic assembly, an air conveying pump, a storage battery, a control center, an anaerobic jar, a liquid conveying pump, an aerobic bed, an anaerobic bed and a connecting rope. The aerobic bed and the anaerobic bed are sequentially suspended below the floating plate in series. Air is introduced into the aerobic bed so as to accelerate the reproduction of aerobic bacteria. The anaerobic bed conveys anaerobic bacteria through the anaerobic jar. Filled biological rope filler is beneficial for the adhesion reproduction of bacteria. Small holes are formed in shells of the aerobic bed and the anaerobic bed so that bacteria diffusion can be facilitated. Thestructure of the repairing device is beneficial for bacteria reproduction; a winding machine, an ultrasonic distance detector, a water body eutrophy detector, an electric propeller, an electric rudder, an anchor and a remote controller are additionally arranged, the water body eutrophy degree is judged, and the repairing device is automatically controlled by a control center or remotely controlled by manpower to move in a water body for repairing and purifying; aerobic bacteria and anaerobic bacteria are used for repairing the water body without being interfered with by each other, the growthand reproduction of the bacteria are rapid, and the water body repairing and purifying effect is good.
