摘要：

A high intensity light system (HILIS) was designed and constructed to define the environmental parameters affecting production of algae. The HILIS incorporates the basic concepts of an aerobic fermenter for heterotrophic cells with high intensity illumination for photosynthetic studies. Of nine parameters considered, temperature and light intensity studies using Chlorella 71105 have been completed. Total illumination was varied from 25,000 to 300,000 lumens (30 times intensity of sunlight as measured at earth's surface) in 7.7–1, culture. The effect of illumination upon growth was measured as cell concentration and total daily algal production when operating the HILIS as a continuous system at a dilution rate of 0.91 per day. Growth may be expressed as a long function of illumination. A maximum algal concentration of 25.5g/l., dry weight basis, was attained at 300,000 lumens. Copyright © 1969 John Wiley & Sons, Inc.
