Summary, etc. |
<p class="Body"><span>The selective behaviour of lauryl alcohol to catalyze esterification for the synthesis of tuna free fatty acids (TFFAs) using immobilized </span><em>Pseudomonas cepacia</em><span> (PCL) and </span><em>Thermomyces lanuginosus</em><span> lipases (TLL) have been investigated. The characterization of both immobilized PCL and TLL and their support immobead-150 is carried out using particle size analyzer, BET method and FT-IR. The suitable reaction conditions have been determined as lauryl alcohol to TFFAs ratio 4:1 (wt/wt), </span><em>p</em><span>H 8.0, buffer to TFFAs ratio 1:1 (wt/wt), temperature 50°C and agitation speed 800 rpm. Reusability of both the immobilized lipases for esterification has also been carried out and the activity was stabilized at 60.9% and 47.6% after 5 cycles of repeated use of immobilized PCL and TLL, respectively. Maximum 93.8 wt% Docosahexaenoic acid is recovered in esters with immobilized PCL after 16 h.</span></p> |
