| Abstract: | The blue-green alga - Nostoc commune is distributed in China, and is proved one of the valuable economic species among blue-green algae. Conditions of the growth of this alga was studied on liquid medium in culture. The results of our experiments demonstrated that this blue-green alga grews better under the scattered light with light intensity 2200lux, 25℃, and pH of 8. Maximum percentage of the growth of Nostoc commune was obtained at Ca 2+ -ion concentration 0.02%. |
