节能灯替代白炽灯为光源对光合细菌SXY-8菌株生长及活细胞吸收光谱的影响
Effects of Illuminant with Energy-saving Lamps Replacing Incandescent Lamps on Growth and Absorption Spectra of Photosynthetic Bacteria SXY-8
摘要
Abstract
In order to explore the possibility of energy-saving lamps that replaced incandescent light sources for culturing photosynthetic bacteria,the growth and living cells absorption spectra of photosynthetic bacteria SXY-8 producing 5-aminolevulinic acid(ALA)at the same light intensity of energy-saving lamps and incandescent lamps and at the different light intensities of energy-saving lamp were compared. At the same light intensity,the tests showed that SXY-8 at the incandescent lamp than energy-saving lamps arrived the logarithmic growth phase 8 h in advance,and bacteriochlorophyll content was higher,but the concentration of the culture and the absorption spectra of carotenoid and bacteriochlorophyll of living cells were same at the two light sources. Growth rate of SXY-8 at 8 W energy-saving lamp was significantly (P<0.05) higher than at 14 W energy-saving lamp,and the concentration of the culture at 8 W (820 Lux)and 14 W (1 500 Lux)energy-saving lamp were similar and high,and energy-saving lamps could replace incandescent lamp as the light source for culturing photosynthetic bacteria SXY-8 producing ALA.关键词
