Title:
MARINE MICRO-ALGA PRODUCING ETHANOL
Document Type and Number:
Japanese Patent JP3837589
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To obtain a marine micro-alga that can produce ethanol and to provide a process that can efficiently produce ethanol by using the micro-alga in no need of a large amount of water and even in a dry region having reduced amount of rain fall.
SOLUTION: This is a micro-alga in Chlamydomonas that grows in an aqueous solution containing salts of sea water concentrations to accumulate starch in its cells and produce ethanol from the starch in the cells by keeping the cells in a dark and anaerobic atmosphere. The ethanol is by culturing a micro- alga, Chlamydomonas sp. MT-JE-SH-1 in an aqueous solution containing the salts of the seawater concentrations to accumulate starch in the cells of the micro-algae. Then, the slurry including the cell bodies of the micro-algae cultured is held in the dark place and anaerobic atmosphere, while the pH of the culture mixture is kept at 6.0-9.0, thereby forming ethanol.
