Showing SEM micrographs of R. africanum under nitrate and phosphate stress. (a) Untreated intact cell (×1.0 KX). (b) Disintegrated cell wall polysaccharides of AN treated cell (×1.0 KX). (c) Cell with degraded cellulose macrofibrils in AP condition (×1.0 KX). (d) Cells become swollen and rectangular to oval in DDP media (×256 X). (e) A terminal cell with folded margins in DDP treated condition (×1.0 KX). (f) Cross wall with greater folding of cellulosic macrofibrils in DDN treated cell (×500 X).
