工程菌所产黑色素对生物大分子光保护作用的研究

摘要

研究了黑色素在防止紫外线照射引起的DNA双链断裂方面的作用，并探讨了该黑色素对B.t.的毒素蛋白和杀虫活性的光保护作用.%Studing melanin on the prevent function of DNA duplex breakage byUV irradiation, this paper discusses the protection of B.t. toxin protein and insecticidal activation against UV irradiation by melanin from engineering bacteria(E.Coli/p WSY).
