[Effects of light quality on the growth characteristics and biochemical component of Chlorella pyrenoidosa].

Effect of light quality, including red light, blue light, white light, red and blue mixing light with ratios of 8: 1, 8:2 and 8 : 3, on the growth characteristics and biochenmical composition of Chlorella pyrenoidosa was investigated based on light emitting diode (LED). Results showed that Chlorella pyrenoidosa grew best under blue light, and the optical density, specific growth rate and biomass of Chlorella pyrenoidosa was about 2.4, 0.

[Study on the Chlorella pyrenoidosa cultivation technology based on the excess sludge utilization].

Microalgae cultivation based on the waste water or other reused waste can not only make rational use of the waste, but also provide cheap materials for microalgae production. In the present study, Chlorella pyrenoidosa was used to develop a new way for microalgae cultivation based on the mix culture media with different ratio of sludge extracts and SE (selenite enrichment). Results showed that after 14 d cultivation under the same cultivating condition, the absorbency of C.
