激光对生产β-胡萝卜素的藻种——盐生杜氏藻(Dunaliella salina)诱变的研究
Studies on laser-mutagenesis of β-carotene producer Dunaiiella salina
摘要
用激光(335 nm,0.014 MW/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0.48 mg·100 ml-1天-1,比原藻增加19％。
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%.
