1. Growth requirements of blue-green algae containing only the c-phycocyanin -[-chlorophyll a pigment system have been studied under blue light (380--540 nm) which approximates light conditions existing in subsurface waters in nature. 2. While a few species were capable of very slow photosynthetic
After exposure of cells to N-methyl-N'-nitro-N-nitrosoguanidine a series of stable mutants of the marine coccoid blue-green alga, Agmenellum quadruplicatum, were isolated. 1. Two of these mutants were blocked at nitrate reductase and required nitrite or ammonium ion for growth. 2. Four of the muta
