PURPOSE:To obtain photo-setting type biocapsules easily and inexpensively, by a method wherein a photo-setting resin and a photopolymerization initiator are ingested by true fungi such as yeast to form photo-setting type biocapsules. CONSTITUTION:A photo-setting resin and a photopolymerization initiator are ingested by true fungi such as yeast, followed by a treatment at 35-70 deg.C to form photo-setting type biocapsules. The photo-setting resin enclosed in the cap?sules may be, for example, a photo-dimerized type resin having a photosensitive group such as a cinnamic acid residue, a cinnamylidene residue and alpha,beta-unsaturated ketone residue. As the photopolymerization initiator, a known compound such as benzoin alkyl ether and benzophenone can be used. Yeast may be in any of various forms suchas oval, lemon-like and cylindrical form, and the diameter thereof is preferably 5-20mum. |
