The process consists of culturing in a closed photobioreactor (2) microalgae suspended in a culture medium (1), the oxygen produced by the microalgae by photosynthesis being collected and then reinjected into the culture medium, separating (6) the microalgae from the culture medium (1), dissolving (12) the microalgae, grin- ding or crushing (14) the solution of microalgae, adding (16) a solvent to the ground or crushed solution for solubilizing the antioxidants pro- duced by the microalgae and then separating (18) the liquid phases present.

A process for improving freeness of paper pulp which comprises these steps: a) Adding to the pulp at least 0.05~o based on the dry weight of the pulp, of a cellulolytic enzyme; b) Allowing the pulp to contact the cellulolytic enzyme for at least 20 minutes at a temperature of at least 20 degrees C.; c) Adding at least 0.0007% based on the dry weight of the pulp of a water soluble cationic polymer, and then d) Forming the thus treated pulp into paper.
