%X 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 (x 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 into Sp-Z(L), The contents of carotenoids and phycobilins raised 23% and 12%, respectively, but the contents of chlorophylls dropped 14.5%, and the growth rate dropped 36% too. The results probably showed that the decrease of chlorophylls was one of the main reasons that caused the remarkable decrease of the growth rate of Sp-Z(L).
