Characterization of Polyhydroxybutyrate Nanoparticles
Iraqi Journal of Science, 2022 Preparation of nanoparticles is one of the important ways to increase the biological effectiveness of materials. There are several methods to prepare the polyhydroxybutyrate (PHB) nanoparticles. Here, a new method is used based on exposing PHB to ultrasound waves under variable pH conditions.

Production of polyhydroxybutyrate in sugarcane
Plant Biotechnology Journal, 2006 SummaryWe report here the production of the bacterial polyester, polyhydroxybutyrate (PHB), in the crop species sugarcane (Saccharum spp. hybrids). The PHB biosynthesis enzymes of Ralstonia eutropha [β‐ketothiolase (PHAA), acetoacetyl‐reductase (PHAB) and PHB synthase (PHAC)] were expressed in the cytosol or targeted to mitochondria or plastids.

Enhanced polyhydroxybutyrate production in transgenic sugarcane [PDF]
Plant Biotechnology Journal, 2012 SummaryPolyhydroxybutyrate (PHB) is a bacterial polyester that has properties similar to some petrochemically produced plastics. Plant‐based production has the potential to make this biorenewable plastic highly competitive with petrochemical‐based plastics. We previously reported that transgenic sugarcane produced PHB at levels as high as 1.8% leaf dry
