| 摘 要： | 采用半导体激光(波长650nm,功率40mW,功率密度13mW/cm2)辐照钝顶螺旋藻,辐照时间为30min、15min、8min.通过测定藻丝形态参量、叶绿素a、β胡萝卜素,研究半导体激光对藻生长的影响.结果表明:三个辐照时间都对藻丝形态产生影响,使藻丝长、螺旋数、螺旋长发生变化;30min辐照组抑制藻体叶绿素a、β胡萝卜素的合成,8min和15min辐照组促进藻体叶绿素a和β胡萝卜素的合成,β胡萝卜素增幅最高达17.9%.8min促长作用最明显,使比生长速率提高10.9%,15min略有促长作用,而30min则起抑制生长作用.

| Abstract: | Spirulina platensis was irradiated with does of 30min,15min,and 8min of LD laser (wave length 650nm,power 40mW,power density 13mW/cm 2).The following parameters were used in assays:morphology,chlorophyll a and β-carotene.The results showed:three does of LD laser affected the filaments morphology,the length of filament and thread pitch and helix numbers were variety compare to initial strain.The dose of 30min restricted chlorophyll a and β-carotene,but 8min and 15min does stimulated chlorophll a and β carotene,and carotene productivity increased most by 17.9%,also 30min restricted the growth speed,but 8min promoted in best. |
