Abstract

The invention belongs to the technical field of bio-fertilizer, particularly relates to bio-organic fertilizer prepared from soy protein wastewater sludge, and further discloses a preparation method of the bio-organic fertilizer. The preparation method of the bio-organic fertilizer includes: bacillus stearothermophilus, streptomyces albus, fine candida and staphylococcus epidermidis are used as a composite fermentation microbial agent to perform aerobic fermentation on the protein sludge so as to prepare the bio-organic fertilizer. The prepared bio-organic fertilizer is high in nutritive value and can be used as organic fertilizer.

Description

technical field [0001] The invention belongs to the technical field of biological fertilizers, in particular to a biological organic fertilizer prepared from soybean protein wastewater sludge, and further discloses a preparation method thereof. Background technique [0002] With the improvement of people's living standards, great changes have taken place in people's dietary structure, the intake of protein per capita is increasing day by day, and because animal protein contains cholesterol, long-term consumption can easily induce diseases such as cardiovascular and cerebrovascular diseases, obesity, etc. The intake of vegetable protein is more important. [0003] Among the many vegetable proteins, soy protein (also known as soybean protein) has the highest nutritional value. Soybean protein powder is obtained from low-temperature defatted soybean meal through extraction, separation, enzymatic hydrolysis, spray drying and other steps. Enzymatic hydrolysis can decompose large...
