Increase of lipid content in microalgae by triacylglycerol (TAG) lipase gene manipulation

摘要

The present invention , organisms using the regulation of triacylglycerol (TAG) lipase activity , a method for increasing the lipid content in the particular microalgae . The present invention obtained by the above method , organisms or micro- algae lipid content is increased , as well as in industrial and medical further relates to their use in order to obtain particularly omega- 3 unsaturated fatty acids . The present invention , nucleic acid from Phaeodactylum tricornutum encoding a new TAG lipase , and the proportion of fatty acids in the biomass , in particular further relates to the use of the nucleic acid when it affects the content of polyunsaturated fatty acids .
