螺旋藻品系Z中不同形态藻丝体的生长速率和光合色素比较

摘要:

The line-shaped filaments Sp-Z(L) were isolated and cultured from Spirulina platensis Sp-Z. The growth rate of Sp-Z(L) was only 64% as much as that of SP-Z when the light intensity was 4000 Lux. The contentS (×10-3 g / g dry weight) of chlorophylls, carotenoids and phycobilins of Sp-Z(L) and Sp-Z were 20.6, 0.343, 5.00 and 24.1 0.297, 4.46, respectively. Moreover, as to the absorption spectra of the three photopigments of SP-Z(L), red shifts were observed. Therefore, after the spiral Sp-Z breeded or changed…
