Abstract

Anabaena doliolum grown under molybdenum deficiency produced less biomass (on a dry wt basis) and the cells had lower protein content but higher carbohydrate content than Mo-grown material. Molybdenum deficiency led to a slight decrease in chlorophyll a, a 1.5-fold increase in carotenoids and a 1.4-fold increase in total lipid but there was no difference in the lipid profiles of Mo-enriched and Mo-deficient cells. Molybdenum deficiency caused increases in the cell contents of digalactosyl diacylglycerol and phosphatidylglycerol and decreases in monogalactosyl diacylglycerol and sulphoquinovosyl diacylglycerol lipids. The concentration of unsaturated C18 fatty acids was lower in the Mo-deficient cells.
