Title:
ETHANOL PRODUCTION FROM OCEAN BIOMASS
Document Type and Number:
WIPO Patent Application WO/2011/024858
Kind Code:
A1
Abstract:
Provided is a method for producing ethanol from polysaccharide alginic acid, large amounts of which are found in brown algae. Said method uses the ability of Sphingomonas sp. A1 to metabolize alginic acid and the powerful ability of bacteria such as Zymomonas mobilis to produce ethanol. In the provided method, which produces ethanol using alginic acid as a starting material, a gene coding for a protein and enzyme related to alginic acid metabolism, derived from Sphingomonas sp. A1, and a gene coding for an enzyme related to ethanol production are combined in one microorganism. Said microorganism is cultured in a culture medium that contains alginic acid.
