Polyhydroxyalkanoates (PHAs) are polyesters of hydroxyacids (HAs) with the general structural formula as depicted in Figure 1 Where X varies from 600 to 35,000 n = 1 R = hydrogen Poly (3-hydroxypropionate) R = methyl Poly (3-hydroxybutyrate) R = ethyl Poly (3-hydroxyvalerate) R = propyl Poly (3-hydroxyhexanoate) R = pentyl Poly (3-hydroxyoctanoate) R = nonyl Poly (3-hydroxydodecanoate) n = 2 R = hydrogen Poly (4-hydroxybutyrate) n = 3 R = hydrogen Poly (5-hydroxyvalerate) (Ojumu et al., 2004).
