    摘要: To provide a new method for efficiently producing theanine, by which theanine is simply and industrially advantageously produced. Pseudomonas citronellosis GEA, which is newly separated/selected from natural soil, belongs to the genus, Pseudomonas, and the species citronellosis and is theanine producing bacteria with activities of transferring γ-glutamyl group. Theanine is extremely efficiently produced by using glutaminase derived from the bacteria in a mixture of glutamine and ethylamine at pH 9-12 in comparison with a conventional method.

    摘要: A method for efficiently producing theanine is provided, wherein glutamine and ethylamine are reacted byPseudomonas citronellosis GEA FERM BP-8353, which is newly separated/selected from natural soil, belongs to the genus, Pseudomonas, and the species citronellosis and is a theanine producing bacteria with activities of transferring the γ-glutamyl group. Theanine production increased by four times by using glutaminase derived from the bacteria in a mixture of glutamine and ethylamine at a pH in a range of 9-12 in comparison with conventional methods.
