(Table 3.2)(Pagliano et al., 2017). Polyhydroxyalkanoic acids formed by microbes
are the building blocks of biodegradable elastomers and thermoplastics presently in
use, or candidates to be used, within the pharmaceutical and medical industries in
addition to agriculture (Suriyamongkol et al., 2007). The PHAs production mainly
occurs when cells are cultivated with an abundant source of carbon and cell growth
is limited by the absence of other nutrient, such as oxygen, nitrogen, sulfur, or
