Company introduction
PhaBuilder with cutting-edge synthetic biotechnology
PhaBuilder is a company with leading synthetic biotechnology, focusing on the transformation and engineering of halophilic microorganisms.

PhaBuilder was founded in February 2021 by Professor Guoqiang Chen, director of the Center for Synthesis and Systems Biology at Tsinghua University. It mainly uses the cutting-edge "Next Generation Industrial Biotechnology(NGIB)" to develop and produce a variety of high-value-added products such as PHA - a biodegradable material, ectoine - a pharmaceutical intermediate, and cadaverine - a Nylon 56 precursor. 

PhaBuilder currently has two PHA plants under construction - the synthetic biology intelligent development plant in Beijing China-German Industrial Park and the 10 kt/annum plant in Yichang, Hubei Province. It also plans to build up 3-5 large-scale production bases throughout China within five years. 

At present, PhaBuilder has completed two rounds of financing, raising around 300 million yuan in total. The investors include Sequoia Capital, China State-owned Enterprise Mixed Ownership Reform Fund, and GRC SinoGreen Fund, etc. 

In the future, PhaBuilder will constantly promote synthetic biotechnology to deeply integrate with people's lives and upgrade the intelligent biological manufacturing industry, in order to achieve PhaBuilder's core mission of "Using microbes to change the world and build a green future".

Development and produce a variety of high value-added products, including PHA - a biodegradable material, ectoine - a pharmaceutical intermediate, and cadaverine - a nylon 56 precursor, etc.
Cross-industry Partnership
Cross-industry Partnership
PhaBuilder has established partnership with Angel Yeast Co.,Ltd (listed), North China Pharmaceutical Group Corporation (listed), Meituan Green Tech Fund, Engelbart Wuhan Biologische Verfahren GmbH, and Novozymes (China) Biotechnology Co., Ltd.
Efficient production
Efficient production
The non-sterile system makes it possible to ferment continuously during production, which along with the simple operation and standardized process, highly improves the production efficiency.
Non-food crops
Non-food crops
Through green innovative technology, PhaBuilder can use straw hydrolyzate, kitchen treatment products, waste glycerin, molasses and other products for production, reducing food consumption.
Multi-functional bacteria
Multi-functional bacteria
Only one strain (halophilic bacteria) can produce a variety of products, such as PHA, ectoine, cadaverine, inositol, carotenoids and other materials.
