The growth of H. fusiformis was determined by weighting the fresh algae every two days and the photosynthetic oxygen evolution was assayed by a Clark-type oxygen electrode. To determine the contents of chlorophyll a and UV-absorbing compounds, methanol extracts from H. fusiformis were scanned from 250 to 750 nm. The concentration of chlorophyll a was calculated using the equation of Porra and the contents of UVAC per fresh mass were estimated by determining the ratio of UVAC to chlorophyll a according to Dunlap et al and multiplying the ratio of chlorophyll a content to fresh weight of the sample used.
