WebWe demonstrate a novel strategy to produce ( R )-3-hydroxybutyric acid [( R )-3-HB] using Pseudomonas sp. DS1001a or its extracellular poly (3-hydroxybutyrate) (PHB) depolymerase. While approximately 77.8% PHB was degraded by Pseudomonas sp. DS1001a after 12 h of cultivation, only 1.555 g/l of 3-HB monomer was produced because … WebAug 1, 2024 · DOI: 10.1016/J.POLYMDEGRADSTAB.2024.06.002 Corpus ID: 89893246; Purification, characterization, and gene cloning of an Aspergillus fumigatus polyhydroxybutyrate depolymerase used for degradation of polyhydroxybutyrate, polyethylene succinate, and polybutylene succinate high school backpacks for athletes
