The results showed a spectrum
with the presence of three groups of signals characteristic of
the medium chain length Polyhydroxyalkanoate (mcl-PHA):
at 2.5 ppm attributed to the methylene group, at 5.2 ppm for
the methine group adjacent to an asymmetric carbon atom
and at 1.6 ppm characteristic of the methylene protons
adjacent to the b-carbon in the side-chains group (Figure 5).
