Project Summary
The project scope is to
create and perform experiments on a purification system for contaminated water
containing phenols and dyes. The system will consist of a fluidized bed reactor
(FBR) and a catalyst made of co-immobilized enzymes on solid supports composed
of recycled polyethylene terephthalate (rPET) as core, and chitosan (Cs) and
polyacrylic acid (PAA) as shell. Also, the project aims to implement an
ecological approach utilizing biocatalysis to effectively eliminate hazardous
or persistent substances from water. The project team desires to generate a
biocatalyst by co-immobilizing two enzymes - Laccase from Aspergillus (Lc) and
Tyrosinase from mushrooms (Tyr) - on solid supports composed of a rPET core and
a polymeric shell. One of the innovative solutions is the support activation
with carbodiimide alternated with the enzyme immobilization, in repetitive
procedures. The project encompasses 4 objectives: obtaining and characterizing
co-immobilized tyrosinase and laccase on recycled polyethylene terephthalate
coated with polyacrylic acid and chitosan; operational stability of
co-immobilized rPET-Cs-PAA-Lc-Tyr products in synthetic and real wastewaters;
design of a lab-scale fluidized bed reactor with co-immobilized enzymes to be
applied in wastewater treatment; validation of the operational efficiency of
the fluidized bed reactor and co-immobilized enzymes system for treatment of
bisphenols and dyes from real wastewater.
