- Abstract
The industrial limitations for the use of enzymes are mainly related to their catalytic capacity and their high cost. Herein, it is proposed to evaluate the productive capacity of Burkholderia cepacia lipase (free enzyme and cross‐linked enzyme aggregates – CLEAs) for the hydrolysis and esterification reactions of licuri (Syagrus coronata (Mart.) Becc.) oil, also addressing different strategies to optimize the processes for the reuse of this valuable biocatalyst. For hydrolysis reactions, it was obtained an increase of 178 % in fatty acids productivity using CLEAS compared to free enzymes. By submitting the system to liquid‐liquid separation, it was possible to reuse the free enzymes, which maintained a relative conversion of approximately 75 % of the initial cycle. For the esterification reaction, CLEAs showed a productivity increase of 50 times with lauric acid and 15 times with palmitic acid; in addition to being recovered and reused for 5 cycles, with little loss of efficiency, showing good resistance to the organic environment.
