62-50-0 - Biological effects of ethyl methanesulfonate on rhombohedral microcrescentic algae
from VIP Journal Professional Edition
Author:
Yang Mao pure , Zhao Geng Mao , Wang Changhai
Abstract:
in order to improve the oil-producing ability of Nitzschia cesterium and to obtain a mutant strain with high oil content, ethyl methanesulfonate (EMS) was used to chemically mutagenize the strain, and its biological effects were investigated. The results showed that EMS had a good mutagenic effect on the small Crescent, after treated by 0.1 mol/L and 0.05 mol/L EMS, the mutant algal strains YA and YB with strong oil production ability were obtained, respectively, under the same culture conditions, the relative contents of chlorophyll a, carotenoid, protein, soluble sugar and oil in the unit volume cells of the two mutant algae increased by 30.05% and 25.77%, respectively, compared with the control group, 22.15% and 19.26%, 9.06% and 8.27%, 48.25% and 45.48%, 44.06% and 12.86%.
