Shandong Yangcheng Biotechnology Co., Ltd. was founded in 2009, with a registered capital of 11.7 million yuan and total corporate assets of 118 million yuan. The company is a high-tech enterprise engaged in the research and development, production and operation of pharmaceutical intermediates, food and feed additives. It covers an area of 84.44 mu and has a total construction area of 22,000 square meters. It has built general fermentation workshops, enzyme conversion workshops, refined drying and packaging workshops and other production auxiliary facilities such as perfect sewage treatment.

The company currently has 260 employees, including 45 R&D personnel, among whom there are 3 professors, 3 senior engineers, 10 personnel with intermediate titles, 4 doctoral students and 12 master students. It has gathered a large number of biological engineering technology, industrial and management talents. After years of technical R&D and industrial practice, an excellent team with strong creativity and competitiveness has been built, and many technical achievements developed by the company are at the international leading level. During this period, it has obtained 6 invention patents, 2 software copyrights, 11 patents under application and acceptance, and 5 scientific and technological achievement appraisal certificates. In 2018, it won honors such as "Gazelle Enterprise", "Shandong Provincial Engineering Laboratory", "Shandong Provincial Recognized Enterprise Technology Center", "Shandong Provincial Small and Medium-sized Enterprises Hidden Champion", "Shandong Provincial Amino Acid Biological Enzyme Development and Application Engineering Technology Research Center" and "Shandong Provincial Enterprise Technology Innovation First Prize".

The company has abandoned the original high-energy-consumption and high-cost chemical products, and has transformed into a circular economy model with recyclable raw materials and products. The production process has replaced animal sources with non-animal sources, and biological methods with chemical synthesis methods and plant extraction methods. Compared with traditional processes, it has unique advantages such as high yield, high purity, low energy consumption, safety and sustainable development.

The company currently has five series of products: fermented L-tyrosine series, glutamic acid series, alanine series, tryptophan series and organic nitrogen source series. Among them, the fermented L-tyrosine is the flagship product, and derivative products (tyramine, tyramine hydrochloride, acetyltyrosine, butyric acid, etc.) are produced around tyrosine. Based on amino acids such as glutamic acid, alanine and tryptophan, a series of derivative products are produced by fermentation and biological enzyme conversion, thus forming a complete industrial chain.
