Title:
LIPASE MUTANT OF EUKARYOTIC MICROALGA
Document Type and Number:
WIPO Patent Application WO/2017/038995
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a eukaryotic microalga in which triacylglycerol (TAG) accumulation is improved, and which can proliferate even under short photoperiod conditions. Specifically, the present invention relates to a eukaryotic microalga mutant in which the TAG lipase activity of the SDP1 protein has been reduced, wherein intracellular TAG accumulation is increased and/or there is improved proliferation under short photoperiod cultivation conditions compared to the parent strain.
