The present invention relates to a process for producing biofertilizers/biostimulants from microalgae with intensive CO.sub.2 capture, which comprises the following steps: a) preparing an inoculum; b) cultivating for the production of microalgae biomass in a window photobioreactor; c) collecting the biomass by flocculation; d) drying the biomass, and grinding and extracting a polar fraction by solvent in a two-phase system; and e) analyzing the polar fraction by liquid chromatography.

The invention also relates to the extracts of wet biomass of the microalgae Scenedesmus sp., obtaining the polar fraction. This polar fraction contains amino acids, sugars, betaine derivatives, vitamin B3 (nicotinamide or nicotinic acid) and pantothenic acid (vitamin B5), the monoterpene loliolide and the tryptophan derivative indole-lactic acid (analogous to indole-acetic acid, a phytohormone of the auxin class).

The polar fraction can also be used as an input in the cultivation of soybeans, corn, sugar cane, cotton and coffee, among other cultivated species.

The present invention is directed to isolated thraustochytrid microorganisms as well strains and mutants thereof. The invention is further directed to biomasses, microbial oils, compositions, cultures, methods of producing microbial oils, and methods of using the isolated thraustochytrids, biomasses, and microbial oils.

A method for producing biomass from a microalgae includes culturing the microalgae in an effluent diluted in seawater. A method for bioremediating an effluent includes culturing a microalgae in the effluent diluted in seawater. The microalgae is at least one of a strain of the genus Nodularia, a strain of the genus Chrysoreinhardia, a strain of the genus Halochlorella, or combinations thereof. At the beginning of culturing, the diluted effluent exhibits concentrations of total nitrogen (N) in the range of 30-150 mg/l and concentrations of total phosphorus (P) in the range of 1-15 mg/l. The N/P quotient is in the range of 5-40.
