Abstract EN
Tyrosol hydroxylating Pseudomonas strain was previously isolated from olive mill wastewaters-irrigated soil.
In the present work, experimental design was used to study the bioconversion of tyrosol in laboratory fermenters aiming at the recovery of the highest yields of hydroxytyrosol.
The effects of biocatalyst loading and tyrosol concentration were studied.
The bioconversion yield reached 86.9% (37.3 mM hydroxytyrosol) starting from a tyrosol concentration of 43 mM.
Under these conditions, the specific productivity relative to the biocatalyst was 4.78 μM/min/g.
The established model to predict bioconversion yield was validated in two bench-scale fermenters.
At the downstream stage, the reaction product was recovered as a hydroxytyrosol rich solution after microfiltration and concentration under vacuum.
Subsequent to this operation, hydroxytyrosol composition yielded 73.8% of the total dry matter.
