The invention relates to a plant and process for producing photosynthetic microorganisms, particularly microalgae, in a photobioreactor (14) using CO2 (42) and heat from waste from a siderurgical plant (102). The use of low-temperature thermal waste, which cannot generally leverage for other uses, makes the system very economical. The thermal waste transfers its heat through a heat exchanger (34) to the cultivation water. Carbon dioxide discarded from metallurgical plants, and, in particular, steel plants, is transformed into valuable biomass, particularly microalgae. Produced microalgae serve, for example, for nutrition, for the extraction of biomolecules of nutraceutical or pharmaceutical interest and for biofuel production (114).

The present invention relates to a microalgal strain of the species Nannochloropsis gaditana. More in particular, the present invention relates to a microalgal strain of the species Nannochloropsis gaditana, characterised by a mutation of an enzyme involved in the biosynthesis of chlorophyll that changes the physiology thereof with respect to the wild-type strain of the same species. In particular, thanks to said mutation, microalgae are formed which, with respect to the wild-type strain of the same species, have a lower chlorophyll content and a reduced capacity to absorb visible radiation (light). Further, the present invention relates to a process for the production of lipids through the cultivation of said mutated Nannochloropsis gaditana strain. The lipids thus obtained can be used as synthesis intermediates, particularly in the so-called "green-chemistry" sector or in the production of biofuels.
