Fishmeal is the most important protein source for aquaculture animals.Rich in essential amino acids (anchovy meal: lys 4.9%, Met 1.9%; herring Powder: lys 5.7%, Met 2.2%) and fatty acids (especially EPA,DHA), and relatively balanced; high digestible energy, carbohydrate content Low; good palatability; low anti-nutritional factors; can be used by aquaculture animals Well absorbed; contains unknown growth factors: such as Se, VB2,Rich in VB12, niacin, choline, small peptides, special immune proteins, etc.Calcium, phosphorus, iron, zinc, iodine, VD, VA, etc.Approximately of global fish catch 30% is used to produce fishmeal, and most of the fishmeal is used in aquatic products feed (FAO, 2011). However, due to global climate change, environmental, Factors such as deterioration and overfishing have caused the decline of fishery biological resources, Fish catches are getting lower and lower, and fishery biological resources used to produce fishmealdecrease. In recent years, global fishmeal production has been between 5 and 6 million fluctuates between tonnes (FAO, 2011). The market demand for fishmeal is strong boom, leading to rapid and continuous rise in fishmeal prices and fishmeal shortages It is one of the biggest problems faced by the global aquafeed industry. It has seriously affected the healthy and sustainable development of the aquatic feed industry and urgently needs countermeasures.solve this problem. Recently, with the rapid rise in temperature, high-priced fishThe pressure put on aquatic feed companies by fish meal is also increasing.Substitution has always been the focus of global aquatic animal nutrition and feed scholars and aquatic productsA hot topic in feed enterprise research.1 The necessity and feasibility of fishmeal substitutionmy country is the world's largest aquaculture country, and its aquacultureThe total amount accounts for about 70% of the global share, and the total aquatic feedProduction exceeds 60% of global aquafeed production and is the largest Fishmeal consuming countries.   We produced bio-enzyme protein powder with 80% crude protein , and crude protein digestibility is above 95%,this product can replace imported steamed fish meal or other animal-derived protein raw materials, and the addition amount in the full-price feed is about 5%. it can save cost and increase the digestibility rate.  

Methanol protein is a single-cell protein produced by culturing microorganisms using methanol as a carbon source. It has the advantages of low cost, stable and controllable quality. Methyl protein is also considered an effective alternative to food and feed protein. Recently, the nutritional resources synthetic biology team led by researcher Wu Xin of the Tianjin Institute of Industrial Biotechnology, Chinese Academy of Sciences, with the support of the "Protein Feed Bioengineering Manufacturing Frontier Technology and New Product Creation" project, biosynthesized one-carbon methanol raw materials in single cells. New breakthroughs have been made in protein. This study provides a new strategy for analyzing the regulatory mechanism of efficient utilization of carbon and nitrogen sources and directional synthesis of methanol-protein in Pichia pastoris, and also lays the foundation for breaking through the economic threshold of methanol-protein biomanufacturing. Relevant research results were published in the international journals "Microbial Cell Factory" and "Biofuels and Bioproduct Technology"   Methanol protein can replace natural plant protein At present, my country's dependence on foreign countries for bulk agricultural products is still high. Among them, the foreign dependence on protein raw materials such as soybeans has exceeded 80% for more than ten consecutive years. High dependence on imported nutritional resources has seriously threatened my country's food supply security. It is urgent to seek new protein resources to replace soybean and other crop proteins. "Single-cell protein is regarded as an important substitute for food and feed protein production. This protein is a bacterial protein produced through microbial fermentation." Wu Xin introduced that the protein content in bacteria is as high as 40%-85%, which is far from Higher protein content than in natural plants. At the same time, the bacterial cells have complete amino acid components and high availability. They also contain nutrients such as vitamins, inorganic salts, fats and sugars, and can partially replace fish meal, soybeans, meat and skimmed milk powder. Compared with obtaining protein through traditional planting methods, single-cell protein production is not affected by the natural environment and has a higher yield. With the same output, the land use efficiency for single-cell protein production is more than 1,000 times higher than that for crop cultivation.
