| Abstract: | Anabaena flos-aquae were scanned in vivo by fluorescence spectrum.The estimated optimal excitation and emission wavelength of cyanobacterial phycocyanin fluorescence were 620nm,650nm respectively and a linear relationship between anabaena flos-aquae biomass and the phycocyanin characteristic fluorescence intensity was detected.The results impressed that applying fluorescence spectrum to detect the phycocyanin fluorescence intensity and reflect the anabaena flos-aquae biomass is specific and feasible.The met... |
