Title:
NOVEL MICROALGA HAVING AGGREGATION ABILITY
Document Type and Number:
WIPO Patent Application WO/2017/217116
Kind Code:
A1
Abstract:
In the production of ethyl alcohol by taking advantage of autofermentation of a microalga, a step for concentrating or recovering alga cells by centrifugation, filtration, etc. is omitted or simplified so as to save labor and facility required therefor.
The microalga, which belongs to the genus Chlamydomonas sp., is a variant that is able to produce ethyl alcohol under anaerobic and dark conditions and has acquired an ability to grow in an aggregate state. In the ethyl alcohol production method, the microalga is grown and maintained under anaerobic and dark conditions to thereby allow the microalga to produce ethyl alcohol.
