제목 Polymerization of cardanol using soybean peroxidase and its potential application as anti-biofilm coating material
초록 Cardanol is obtained by thermal distillation of cashew nut shell liquid. It is a phenol derivative having a C 15 unsaturated alkyl chain with 1 to 3 double bonds at its meta position (Ikeda et al. 2000). Although it has been used as a raw material for resins and friction lining materials, new applications may be found if it could be polymerized using enzyme technology. The major advantages of enzymatic polymerization are: no need for formaldehyde, which has to be used in chemical polymerization and a good chemoselective conversion. Peroxidase induces oxidative polymerization of phenol derivatives under mild conditions to yield a new class of polyphenols (Huttermann et al. 2001, Echig & Ohno 2001). In this study, cardanol was polymerized using soybean peroxidase and the potential application of polycardanol as an anti-biofouling material was investigated. Until now, there have been no reports on the anti-biofouling characteristics of polycardanol.
Soybean peroxidase (20 mg) catalyzed the oxidative polymerization of cardanol and yielded 62 % of polycardanol in the 2-propanol/phospate buffer solution (25 ml, 50:50, by vol.) during 6 h reaction where stable soybean peroxidase activity was maintained for 2 h. Cobalt naphthenate (0.5 % w/w) catalyzed the crosslinking of polycardanol and the final hardness of crosslinked polycardanol film exceeded 9 H scale as pencil scratch hardness, which shows a high potential as a commercial coating material. In addition, it showed an excellent anti-biofouling activity to Pseudomonas fluorescens compared to other polymeric materials such as polypropylene.
