【摘要】 用激光（335nm,0.014MW/mm²）对产生6-胡萝卜素的盐生杜氏藻（Dunaliella Salina）进行了诱变研究,藻的存活率为90％。诱导后筛选到三个盐生杜氏藻的品系。生长速度较原藻最高增加20％,长度增加7.5％,萨-胡萝卜素生产能力为0.48mg·100ml^-1天^-1),比原藻增加19％。更多还原

【Abstract】 Laser-mutagenesis of -earotene producer Dunaliella salina were investigated. Tie algal survival rate is above 90%. After mutagenesis three mutants were screened, in which the growth rate and length of alga were increased by 20% and 7.5% respectively aa compared with the original D. salina. The productivity of -carotene was 0.48mg-100 ml-1day-1, and waa increased by 19%.更多还原
