The weight loss of standard
homo-polymer P3HB started at around 240 C and its Td5 was
at 269 C, completely decomposed at 295 C (Fig. 4). However
the starting temperature for weight loss of the P3HB produced
by H. palleronii was at around 170 C and its Td5 was at 200 C.
In addition, the P3HB was completely not decomposed at
600 C, 86% was decomposed at 540 C indicating that the
P3HB extracted from H. palleronii composed of 14% inorganic
material which may be came from bacterial dry mass.
