Next Generation Industrial Biotechnology

Next Generation Industrial Biotechnology

Can we develop new biomanufacturing technologies to reduce the dependence on the chemical industry?

The answer is yes!

Using the "Next Generation Industrial Biotechnology" system accumulated and successfully developed by Tsinghua University in the past 30 years, PhaBuilder’s technical team has carried out series transformations on the basis of the halophilic bacteria- originally found in Ayding Lake, Xinjiang/China, to make it more suitable for industrial mass production.
Since then, the technical team of Tsinghua University and PhaBuilder have continued to focus on the development of bacterial strains.
Since 2018, the bacterial strains have been iterated to 20 generations. Now PhaBuilder can use a new metabolic pathway to produce PHB, P34HB, P34HBHV, PHBHHx, PHB5HV, P3HP3HB and other products.

Insights on PHA: A Closer Look
"PHAs can be produced from renewable carbon resources and be completely biodegraded to CO2 and H2O, so PHAs have come under investigation as potential alternatives to petrochemical plastics."
—— Yoshiharu Doi.
Professor, RIKEN Institute, Japan.
"Due to the facts that PHAs are nontoxic and water-insoluble thermoplastic polymers, a high commercial potential arose from their possible applications in industry, medicine, pharmacy, and agriculture."
—— Alexander Steinbüchel.
Professor, Universität Münster, Germany.
"When PHAs are discarded in the environment, they will be completely biodegraded. However, it is interesting to note that PHAs might also be used as a supplementary carbon source for some animals beyond microorganisms."
—— Sang Yup Lee.
Professor, KAIST, Korea.
