Miscibility, properties, and biodegradability of microbial polyester containing blends

Extraction and Characterization of Polyhydroxybutyrates (PHB) from Bacillus thuringiensisKSADL127 Isolated from Mangrove Environments of Saudi Arabia

“…Macrae and Wilkinson (Macrae and Wilkinson 1958) first reported that Properties of biodegradability of PHB produced by B. cereus and B. megaterium. Shape, size, structure, physical properties of these granules differ from organism to organism accordingly (Ha and Cho 2002). Beijerinck was the first to observe lucent granules of PHB in bacterial cells in 1888 (Chowdhury 1963).…”

Exploring biodegradable polymer production from marine microbes

“…Using metabolic engineering approaches, many researches had developed novel PHA homopolymers and this was a new opportunity for polymer production [51][52][53]. These types of polymers are accumulated as intracellular granules in their cytoplasm with varying size, number, monomer composition (> 100), and molecular mass 50,000−1,000,000 Dalton (Da) that are dependent on the organisms [47,54]. The size of the granules ranges from 0.2 to 0.5 μm, which can be clearly visualized by high refractivity in light microscope using staining dyes (Sudan Black B and Nile Blue A or Nile red), PHAs can accumulate 80 % in their cell weight [55,56].…”

Genome Structure ofBacillus cereustsu1 and Genes Involved in Cellulose Degradation and Poly-3-Hydroxybutyrate Synthesis

“…A large number of microorganisms have been found to accumulate PHA as lipoidic storage materials in the cytosol [14][15][16][17]. These microorganisms are mainly divided into four classes (I, II, III, and IV) based on the type of PHA synthases, which are the key enzymes for PHA biosynthesis [18].…”
