Abstract
s, proteases and oxidoreductases as well as two commercial mixtures containing enzymes: Apollo-GreenZyme™ and EOR-ZYMAX™ have been investigated. The group of esterases/lipases has demonstrated the best performance in terms of wettability alteration. Proteases appear to be relatively ambiguous, while carbohydrases and oxidoreductases have the lowest potential for EOR in the light of the present experiments. Application of the commercial product Apollo-GreenZyme™ has also resulted in positive wettability changes, but according to the observations the working mechanisms are different. In an attempt to assess validity of the proposed mechanisms, the reference experiments have been conducted with concentrated enzymes, enzyme product stabilizers, surfactant and protein.
