Improvement of content of the essential amino acids lysine and methionine in Algae and cyanobacteria for improved Animal Feed

摘要

It provides a method to improve the content of lysine and methionine by genetic modification of Algae and cyanobacteria in combination with modified expression of Proteins with a High Content of lysine and methionine as sinks of the amino acids. The method is particularly useful for the production of animal feed.Claim 2: The Method according to claim 1, wherein the up Regulation of lysine is achieved by Transforming the Algae or cyanobacteria with RNAi cetoglutaratorreductasa lysine / sacaropinadeshidrogenasa alga.Claim 3: The Method according to claim 1, wherein the up Regulation of methionine is achieved by Transforming the Algae or cyanobacteria with cystathionine - synthase Mutant of Arabidopsis.
