... the beginning of the experiment, the microalgae cultures were maintained in batch mode but later on they were cultured into continuous and semi-continuous dilution modes. As the experiment continued, the independent variables, including the light intensity, the dilution rate and the N status, were manipulated. The process of photosynthesis was also altered. The six microalgal strains were then observed. Their dry mass, which is the mass of the microalgae, in grams, actually cultivated in the experiment, was weighed and noted. The composition of the microalgal algae, including the percentage of proteins, carbohydrates and lipids present within the drymass of the algae. The oil was extracted from the drymass of the algae through various methods. The actual procedure of the experiment was carried out differently in respect to each microalgal strain. The treatments to each microalgal strain differ in the light intensity, the different batch methods, and the different uses methods ...
