The pigment composition of Chlorella fusca has been investigated in the absence and in presence of vanadate and during iron stress.

1. Fe-deficiency generally decreases algal pigment content without change of the ratio chlorophyll a/b.

2. A twofold vanadate induced increase of the chlorophylls is accompanied by a similar enhancement of several xanthophylls, while lutein remains unaffected.

3. Vanadate stimulates the formation of β-carotene up to 5 fold, the effect being less obvious during iron stress
