摘要： The present disclosure relates to strains of Thraustochyrium genus, including a high content of polyunsaturated fatty acids, and a method of producing a biomass using the same. According to the novel CJM01 microalgae of Thraustochyrium genus of the present disclosure, the content of lipids in the biomass and the content of unsaturated fatty acid such as docosahexaenoic acid in the biomass are high, so that the microalgae itself, a biomass produced by the culturing and fermentation of microalgae, a condensate of the biomass, and a dried product of the biomass are very useful as a feed composition.

摘要： The present invention relates to microorganisms of Escherichia coli having enhanced L-tryptophan productivity and to a method for producing L-tryptophan using the same. More particularly, the present invention relates to an Escherichia coli variant in which repression and attenuation control of the tryptophan operon is released and accumulation of anthranilate is reduced and thereby enhancing L-tryptophan productivity. The present invention also relates to a method for producing L-tryptophan using the Escherichia coli variant.
