Summary
Cultured cells of Lavandula vera were entrapped with photosensitive synthetic resin prepolymers (PVA-SbQ). PVA-SbQ-entrapped cells grew well inside gel matrices and synthesized de novo blue pigments in the presence of l-cysteine as an inducer. The entrapped cells were superior to calcium alginate-entrapped cells judging from cell growth and total pigment productivity. Release of the pigments, which were almost insoluble in water, from the gels was markedly enhanced by the increase in hydrophilicity of the cell-entrapping gels. The entrapped cells could be used repeatedly for the pigment production.
