摘 要:
Chlorella sorokiniana (C. sorokiniana), a type of green microalgae, features broad prospects for applications in such fields as health foods, biodiesel and so on. Microalgae grow through photosynthesis through their chloroplasts, so the source of light in the environment has a considerable impact on the growth of microalgae. The aim of this study was to find the optimal light source for culturing C. sorokiniana by comparing growth and functional compounds under LED mixed light and fluorescent light. C. sorokiniana was cultured at 25°C, photoperiod 12:12 (Light :Dark), aeration 1vvm (Lair Lmedia-1 min-1 ), and cultured with fluorescent lamp or different ratios of red and blue mixed light. The results showed that the OD650nm on the 7th dayof culture: (Red:Blue:Green = 189 : 21 : 45 μmol • m -2• s-1 ) > (63 : 147 : 45) = (fluorescent lamp) = (21 : 189 : 45) = (105 : 105 : 45) > (210 : 0 : 45) = (0 : 210 : 45),
R:B:G =189: 21: 45 μmol • m -2
• s-1
26 was the best mixed LED light source for cultivating
27 C. sorokiniana, which can effectively promote chlorophyll, total carotenoids and PUFAs
28 contents of C. sorokiniana. It is worth mention that if there is no red or blue LED light
29 source, the growth of C. sorokiniana is worse than other mixed light conditions .
