Solicitante:

ENI SPA [IT]

WO_2020115692_PA

Resumen de: WO2020115692A1

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.
