The invention provides a method for performing natural soil greening on slight alkaline land by using a salt-resistant water-retaining agent containing attapulgite. The water-retaining agent comprises attapulgite, acrylic acid, acrylamide, pine needle powder, walnut leaf powder, cassava starch, yam powder, corn stalk powder and bean peel powder. The preparation method comprises leaf powder treatment. The leaf powder treatment comprises a step of monomer solution preparation and a polymerization step. The invention further provides application of the water-retaining agent to trifolium repens plantin in saline-alkali soil. The method has the advantages that the prepared water-retaining agent has high water absorbing capability in distilled water, rainwater, and NaCl solution with a concentration of 0.6%, the capability of water absorption in the distilled water can reach 1030-1300 times the weight of itself, the capability of water absorption in the rainwater can reach 680-820 times the weight of itself, and the capability of water absorption in the NaCl solution with a concentration of 0.6% can reach 390-530 times the weight of itself.

The invention discloses a culture medium which is applicable to culturing staurosporine producing bacteria for producing staurosporine; the culture medium with pH value of 7.0 comprises carbon sources, organic nitrogen sources and inorganic salt, wherein, the inorganic salt comprises calcium salt; the carbon sources are selected from two or more than two of the following three groups of components, namely, A, B and C, wherein, at least two components are selected from different groups, group A: glucose, group B: amidulin, corn starch and potato starch, and group C: oats and maltodextrin; and / or, the organic nitrogen sources are selected from soybean cake powder, yeast extract, yeast cream and kapok meal; and / or, the inorganic salt is also added with magnesium salt. The invention also discloses a method for producing staurosporine from staurosporine producing bacteria by adopting the culture medium. By adopting the fermentation medium for producing staurosporine, the thalli of the staurosporine producing bacteria grows fast, the mycelia are not easy to clot, the yield of fermentation products is high, and the relative potency is optimized 230 percent of a former culture medium.

The invention discloses a ganoderma lucidum liquid spawn medium formula which comprises 6g of peptone, 15g of glucose, 0.5g of magnesium sulfate, 0.5g of monopotassium phosphate, 1g of potato starch, 3g of corn, 3g of cassava starch, 10mg of vitamin B1, 1g of agar and 1000ml of purified water. The invention further discloses a ganoderma lucidum liquid spawn culture method. The culture method comprises the following steps: by taking the ganoderma lucidum liquid spawn medium formula as a basis, performing high-temperature sterilization, inoculating into stock culture, and culturing in a shake table, thereby obtaining the ganoderma lucidum liquid spawn. The ganoderma lucidum liquid spawn medium formula and the ganoderma lucidum liquid spawn disclosed by the invention have the advantages that the culture steps are reduced, the fermentation period is shortened, the growth period is shortened, the pollution rate is low, the cost is low, the yield is low, and the culture method is applicable to large-scale industrial production.

The invention discloses a method using streptomyces lavendulae fermentation to produce alpha-glucosidase inhibitors. The method is characterized in that strain activation, seed fermentation broth preparation and liquid fermentation are performed on the strains of Streptomyces lavendulae UN-8 with the preservation number being No. M2015512 to obtain fermentation broth rich in alpha-glucosidase inhibitors. The method has the advantages that the method can widely use cheap carbon and nitrogen sources such as soluble starch, cassava starch, corn starch, dried corn steep liquor powder and inorganic ammonium salt; the method adopting liquid-submerged fermentation is convenient to operate and implement, free of pollution, high in production efficiency and capable of satisfying the requirements of industrial production; preliminary identification shows that the alpha-glucosidase inhibitors produced by the method are novel alpha-glucosidase inhibitors, the alpha-glucosidase inhibitors can intensely inhibit alpha-glucosidase, and the IC50 of the alpha-glucosidase inhibitors is 321 times of that of the commercially available alpha-glucosidase inhibitor, namely acarbose; in-vivo experiments show that the alpha-glucosidase inhibitors can evidently improve the formation of postprandial hyperglycemia, the effect of the alpha-glucosidase inhibitors is equivalent to that of the acarbose, and the alpha-glucosidase inhibitors can be used for preventing and treating diabetes.

The invention discloses a prawn feed, which contains fish meal, bean pulp, peanut bran, rape seed dreg, saccharomyces cerevisiae, flour, starch, corn oil, fish oil, K2HPO4 and plantain seed total flavonoids. The prawn feed can remarkably improve the survival rate, weight increment rate and stress resistance of the prawn at the same time of ensuring the growth of the prawn. The consumption of the fish meal is remarkably lower than that of the conventional prawn feed at current markets, so the cost of the feed is greatly reduced.

The present invention discloses purple sweet potato sheet jelly and a manufacture technology thereof. The purple sweet potato sheet jelly comprises the following raw materials in weight percentages: 70-85% of purple sweet potato starch, 5-15% of corn starch and 5-15% of tapioca starch. By adding the corn starch and the tapioca starch into the purple sweet potato starch, the manufacture technology can increase the toughness of the sheet jelly and enhance the taste. The purple sweet potato sheet jelly is strong in the cooking resistance, not stick or thick and chewy and tasty. But the addition of the corn starch and tapioca starch cannot be added too much, which leads to the too hard sheet jelly and affects the taste.

The invention belongs to the field of microbes, and particularly relates to a method for continuously culturing bacillus subtilis and a special fermenting system. The method provided by the invention comprises the following steps: (1) transferring stored bacillus subtilis strain to a test tube agarslantculture-medium, performing strain activation, and then, transferring the strain into a triangular flask and a seeding tank for culturing in sequence to prepare a bacillus subtilis seed; (2) taking culture materials including starch, corn powder, soya bean meal, peptone, NaCl, CaCl2, MgSO4.7H2O, KH2PO4, K2HPO4, MnSO4, a defoaming agent and water; (3) after the culture materials in the step (2) are subjected to sterilizing treatment, inoculating the activated and cultured bacillus subtilis seed, and performing three-stage continuous culturing to obtain a fermenting liquid. The bacillus subtilis cultured with the method provided by the invention is stable and uniform in quality; neither mixed fungi pollution nor strain mutation is easily caused; the service life of various detectors is prolonged; the time is reduced; the yield and the production efficiency are improved; the concentration and the spore rate of thalli of the bacillus subtilis are improved.
