Greenase Biosynthesis Ltd. (Xiamen) [天演益合(厦门)生物技术有限公司 in Chinese] was founded in November 2015 by Dr. Ruming Chen (PhD，Cambridge 2004), who now serves as its Chief Executive Officer.  This biotech company is located in Biomed Bay, Haicang, Xiamen, one of the most beautiful seaside city in South-eastern China and nick-named Amoy, which is better known to the Western. Our company is devoted to the biosynthesis of macromolecules and cellular metabolites, which is beneficial to our health and daiy use. For this purpose, our company have a modern research laboratory in Molecular Biology and Protein Science, as well as a GMP-standard production unit.  Our research and development team comprehensively use our knowledge in protein biochemistry, structural biology, cellular metabolism and chemical biology, togethe with protein engineering and gene engineering, to deliberately modify the metabolic pathway in prokaryotic or eukaryotic cells. The application of directed-evolution of key enzymes in biosynthesis, combined with the production capability of "cell factory", helps to improve the high-level production of  recombinant proteins, bioactive-peptides and organic compounds. We are well equipped with several automatic cell bioreactors for high-density fermentation at different levels.  Two preparative HPLC and protein purification system enable us to purify hundred grams of proteins or peptide in a batch. Other instruments also include a preparative vacuum-freeze dryer, high-speed refrigerated centrifuges, large-volume cell centrifuges, high-pressure cell emulsifiers,  -80C freezers, analytical HPLC, DNA and protein analysis instruments.

 Our company is delicated to produce highly pure enzymes, bioactive peptides and organic compounds at industrial scale, at lower cost, and matching o the GMP standards.
