πŸ’‘ SIU Bioconversion Mechanism

Southern Illinois University engineered microbial consortia express cutinases & PETases to cleavage PET into Terephthalic acid (TPA) & Ethylene Glycol (EG). Intracellular assimilation then converts these monomers into single-cell edible proteins rich in branched-chain amino acids.
