Mycoprotein nutrient product

Abstract

The invention provides a preparation method for a mycoprotein nutrient product which can be used in sunny or rainy whether and at a high or low temperature in an aquaculture breeding process. The method comprises the following steps of: (1) culturing rhodopseudomonas palustris by illumination; (2) flocculating and settling by using 0.01 mol.L<-1> poly aluminum chloride (PAC ) under the condition that pH is 7 to 7.5; concentrating to the effective viable count of over 100 billion CFU / ml and the protein content of over 10 percent; centrifuging to obtain a centrifuge product; and (3) mixing the centrifuge product in the step (2), dusty yeast, p-nitrobenzenesulfonic acid sodium and o-nitrobenzenesulfonic acid sodium in proportion to obtain the product of the invention. 1 ton product comprises10 percent of the dusty yeast based on the weight of the product, 1kg of the p-nitrobenzenesulfonic acid sodium and 1kg of the o-nitrobenzenesulfonic acid sodium, and the balance of the centrifuge product obtained in the step (2). The product obtained by the preparation method can provide protein nutrition for breeding aquatic animals and promote algal growth.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a mycoprotein nutrient product. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control, generally including the whole process of growing aquatic products from seedlings under artificial breeding management. There are currently three main types of fertilizers used in the aquaculture industry, namely traditional organic fertilizers, inorganic fertilizers and biological fertilizers. Traditional organic fertilizers have their advantages, but the fertilizer effect is slow, the process of being used by plankton is longer, and a large amount of oxygen in the water body is consumed in the process of decomposition and mineralization, which is not good for the growth of fish and so on; at the same time, in most cases , the utilization efficiency is low, and it is easy to cause water ...

AI Technical Summary

Problems solved by technology

[0003] However, in natural conditions, algae grow very slowly in low temperature and rainy weather, and continuous low temperature and rainy weather in aquaculture will limit the feeding and growth of farmed animals and reduce the breeding benefits

That is to say, in low temperature and rainy weather, on the one hand, the growth of primary producer algae in the water body is inhibited, and the sources of bait for various aquatic animals that feed on phytoplankton and plants are reduced. On the other hand, the appetite of aquatic animals decreases, which greatly Affect the growth of farmed aquatic animals

None of the existing studies have been conducted on this point, and there is currently no good fungus protein nutrition and algae growth-promoting products for aquatic products that can be used in sunny and rainy weather and high and low temperatures
