Comamonas acidovorans DS-17 was isolated from activated sludge and found to produce copolymers of 3-hydroxybutyrate (3HB) and 4-hydroxybutyrate (4HB) at 30 degrees C under growth-limited conditions. When 1,4-butanediol or 4-hydroxybutyric acid was used as the sole carbon source, a P(4HB) homopolymer was produced.

Enzymatic degradation of poly(3-hydroxybutyrate-co-4-hydroxybutyrate) by commercial lipases
Polymer Degradation and Stability, 2012Abstract Polyhydroxyalkanoates (PHAs) are biocompatible and biodegradable polymers utilized in a wide range of applications. Among these applications, low-molecular-mass (LMW) PHAs are currently being applied in different studies such as amphiphilic block copolymer synthesis.

Nanofibers as niche-biomimetic scaffolds exhibit potential in bone tissue engineering (BTE). Here, poly(3-hydroxybutyrate-co-4-hydroxybutyrate) co-polymer (P34HB)/poly(ethylene glycol) (PEG) nanofiber membranes with a high hydrophilicity and mechanical properties were fabricated by introducing PEG to P34HB via electrospinning. The P34HB/PEG nanofibrous

Poly(3-hydroxybutyrate-co-4-hydroxybutyrate), short as P(3HB-co-4HB), was successfully produced by engineered Halomonas bluephagenesis TD01 grown in glucose and γ-butyrolactone under open non-sterile conditions. Gene orfZ encoding 4HB-CoA transferase of Clostridium kluyveri was integrated into the genome to achieve P(3HB-co-4HB) accumulation comparable
