Immobilization of chloroplast

Abstract

Abstract PURPOSE: To immobilize chlorophyll on a polyvinyl acetate derivative having photo- crosslinking stilbazolium groups without loss the activity. CONSTITUTION: Partially or completely saponified polyvinyl acetate having a saponification degree ≥75%, is reacted with a formylstilbazolium compound of formula II [R is H, or (un)substituted alkyl, or aralkyl group; X - is anion] or a styrylpyridinium compound of formula III (R and X - are the same as described above; n is an integer 1W6) or its acetal to give a photo-crosslinkable resin wherein the hydroxyl groups are substituted by the group of formula I (R, X - , and n are the same as described above; m is 0 or 1) at least partly. Chlorophyll is suspended in an aqueous solution of the resin, and if necessary enzymes having the inhibitory action on the lowering activity, are added. The suspension is then cast or applied to a plane to form a film, which is irradiated with light. COPYRIGHT: (C)1980,JPO&Japio
