Abstract

In N-sufficient cells of Chlorella sorokiniana Shihira and Krauss strain 211/8K (CCAP of Cambridge University), assimilation of ammonium was strictly dependent on light and CO 2 , and was severely inhibited by 100 μM atrazine or 10 μM 3-(3,4-dichlorophenyl)-1,1-dimethylurea (DCMU). In N-limited cells, assimilation of NH 4 + took place at similar rates in both light and darkness, which were 1.6-fold higher than the rate of light-dependent assimilation by N-sufficient cells. Assimilation by N-limited cells was inhibited by L-methionine-DL-sulfoximine (MSX), but not by atrazine or DCMU
