Marine microalgae are a promising sustainable source of lipids, omega-3 fatty acids, and carbohydrates. Selected microalgae species belonging to the Bacillariophyceae, Haptophyceae, Eustigmatophyceae, and Prasinophyceae were characterised for cellular content of carbon and nitrogen, and for production yields of lipids, fatty acids, total carbohydrates, and β-glucans. Carbon and nitrogen content showed a hyperbolic decrease with increasing cell numbers for  Chaetoceros calcitrans ,  C. muelleri ,  Skeletonema costatum ,  Tetraselmis  sp., and  Nannochloropsis oculata . Cultures of  Pavlova lutheri  and  Tisochrysis lutea  showed an increase in carbon content per cell, but a decrease in nitrogen content. The total lipid content of  C. muelleri ,  C. calcitrans ,  N. oculata , and  T. lutea  increased with decreasing relative growth rate; however, the highest productivity of lipids was found in  T. lutea  grown at 40% of the maximum specific growth rate. The highest content of eicosapentaenoic acid was found in  C. muelleri ,  C. calcitrans , and  N. oculata , and the highest content of docosahexaenoic acid was found in  T. lutea . The β-glucan fraction of the carbohydrates was highest in  C. muelleri  and  C. calcitrans  and was very low in  N. oculata . Out of the species investigated,  C. muelleri  had the highest production yield of β-glucans, obtained when cultivated at a 40% relative growth rate.
