V. CONCLUSIONS
In order to find out a cheaper microbial production of
biomasses and PHAs we have investigated the capability of
Pseudomonas fluorescens SC4 to convert substrates formed
by fatty acids. The bacterial strain showed successfully
capability for utilizing linoleic acid and the studied polymer was identified as mcl-PHA, however the same good results were not observed in the other tested fatty acids at the same
conditions. It has been proved its potential to produce mcl- PHA in a high content (45.2 wt%) when linoleic acid medium was used as a sole carbon source and giving maximum CDW yield of 6.75 g/L and a PHA productivity of
3.05 g/L after 48 h fermentation in bioreactor. Further study will be fulfilled on the possibility of Pseudomonas fluorecens SC4 to enhance its growth conditions to use more efficiently
linoleic acid and oleic acid as sole carbon sources for production of PHAs by using media optimization technique via other fermentations of fed-batch, repeated batch, and
repeated fed batch processes to increase the economic
