Summary: White, linearly polarized transformed starch amylopectin into amylose. Moreover, it activated α ‐amylolysis of starch, hydrolysis of xylane with xylanase, hydrolyses of chitin with chitinase, chitosan with chitosanase, and, interestingly, influenced production of cyclodextrins with cyclodextrin glycosyltransferase. Effect of duration of illumination of cyclodextrin glucosyltransferase with polarized light had certain effect upon the yield and isomer ration of three isomeric cyclodextrins. Application of the polarized light required 1–2 hour illumination of the enzymes in a small reaction vessel followed by admixture of so activated enzymes to a bioreactor. Further reactions did not require any illumination.
