Synthetic biology of microbes synthesizing polyhydroxyalkanoates (PHA)

Synthetic and Systems Biotechnology, 2016
Microbial polyhydroxyalkanoates (PHA) have been produced as bioplastics for various purposes. Under the support of China National Basic Research 973 Project, we developed synthetic biology methods to diversify the PHA structures into homo-, random, block polymers with improved properties to better meet various application requirements. At the same time,

Biosynthesis and characterization of polyhydroxyalkanoate containing high 3-hydroxyhexanoate monomer fraction from crude palm kernel oil by recombinant Cupriavidus necator [PDF]

, 2012
The potential of plant oils as sole carbon sources for production of P(3HB-co-3HHx) copolymer containing a high 3HHx monomer fraction using the recombinant Cupriavidus necator strain Re2160/pCB113 has been investigated.

Biological Degradation of Phthalates: From Bioremediation to Plastic Waste Valorization

ChemSusChem, Volume 19, Issue 7, 14 April 2026.
Phthalic acid isomers play a key role in the plastics industry, but pose significant environmental and health concerns. This review explores the microbial biodegradation of phthalates and their esters, focusing on bacterial enzymes, catabolic pathways, and cellular uptake mechanisms of phthalates.

Engineering bacteria for enhanced polyhydroxyalkanoates (PHA) biosynthesis

Synthetic and Systems Biotechnology, 2017
Polyhydroxyalkanoates (PHA) have been produced by some bacteria as bioplastics for many years. Yet their commercialization is still on the way. A few issues are related to the difficulty of PHA commercialization: namely, high cost and instabilities on molecular weights (Mw) and structures, thus instability on thermo-mechanical properties. The high cost

Telechelic Polyhydroxyalkanoates/Polyhydroxybutyrates (PHAs/PHBs)

, 2017
Poly(3-hydroxyalkanoate)s, PHAs, are natural polyesters collected as intracellular granules as a result of a metabolic stress upon unbalanced growth, owing to a limited supply of a necessary nutrient and to the presence of an excess of a carbon source [1,2,3,4,5,6,7-8]. PHAs have material properties ranging from rigid and highly crystalline to elastic,
