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
