A SPIROGYA VARIANS 8GY HAVING THE HIGHER RESISTANCE AGAINST OXIDIZING STRESS AND HIGHER GROWTH RATE USING IRRADIATION, AND PREPARATION METHOD THEREOF

摘要

PURPOSE: A Spirogya varians 8GY(KCTC 11713BP) and a method for preparing the same are provided to ensure excellent growth under an oxidative environment and to prevent water pollution. CONSTITUTION: A method for preparing Spirogya varians 8GY(KCTC 11713BP) comprises: a step of irradiating radation to Spirogya varians and selecting survived Spirogya varians; a step of culturing the selected Spirogya varians in a medium and selecting Spirogya varians with improved starch content, resistance against oxidative environment, and growth rate; and a step of isolating starch using Spirogya varians 8GY(KCTC 11713BP) as a main ingredient. The radiation includes gamma ray, X-ray, alpha ray, beta ray, or electronic beam.
