The method provided by the invention has strong processing capability, less occupied field and low energy consumption in a processing process; in the processing process of the human excrement dregs, a biological organic fertilizer and the biologic proteins of maggots of the black solider flies are obtained synchronously; the resource utilization of the human excrement dregs is achieved; waste is changed into valuable articles; not only is the environmental sanitation improved, but also the organic fertilizer and the biologic proteins are produced simultaneously; and the method has quite good application foreground.

The invention provides Bacillus velezensis and a screening culture method and application thereof. The classification name of the Bacillus velezensis is Bacillus velezensis B3-4, the strain is preserved in the China Center for Type Culture Collection on May 29 , 2020, and the preservation number is CCTCC NO: M 2020160. The screening culture method comprises the following steps that a sample iscollected and preserved at low temperature; a beef extract peptone culture medium is coated with diluent of the sample through a gradient dilution method, and constant-temperature culture is conducted at 15-50 DEG C; after the culture medium grows out bacterial colonies, the bacterial colonies with different forms are selected for streak culture; and then, a circle of bacterial colonies are selected for repeated streak culture, and microscopic observation is combined till the purified strain is obtained. The Bacillus velezensis can effectively degrade and remove organic matter and COD in human excrement and domestic sewage.

The present invention provides freeze-dried compositions that include an extract of human feces and a cryoprotectant, and methods for making and using such compositions, including methods for replacing or supplementing or modifying a subject's colon microbiota, and methods for treating a disease, pathological condition, and / or iatrogenic condition of the colon.

The invention relates to the biological technical field, and in particular, relates to a kit for detecting calprotectin in human feces and a preparation method thereof. The kit uses a specific microsphere conjugate sealing reagent instead of a traditional sealant, and can accurately, quantitatively, quickly and sensitively detect the calprotectin in the human feces.

The invention discloses an intercropping planting cultivation method of oil peony and oil paeonia lactiflora. The method comprises the following steps: (1) selecting a land which is deep, thick and loose in earth, rich in organic substances, sufficient in sunshine, good in draining performance, and low in groundwater level and exposed to the sun; applying mature farmyard manure and slowly-released nutrition particles to the land of each mu, and then deeply ploughing; (2) selecting three-year-old disease-free and healthy seedlings of peony and paeonia lactiflora; (3) digging holes in the prepared earth based on the planting spacing of 40-50 cm*20-25 cm; planting a three-year-old oil peony seedling in each hole; digging holes with the depth of 15 to 20 cm for paeonia lactiflora among the row spacing of the oil peony, and planting a three-year-old oil paeonia lactiflora seedling in each hole; heaping with earth; slightly upwards lifting the seedlings to enable the roots to be in close connection with the earth; covering with earth and compressing; pouring little human feces and urine to fix the roots; covering with fine earth which is higher than the ridge surface; (4) loosening the earth and weeding three to four times each year, and timely hoeing after raining.
