Abstract
A methane-utilizing microorganism capable of producing L-amino acid, for example, bacteria belonging to type I, type X or type II in the taxonomic categorization methane-utilizing bacteria such as Methylomonas albus, Methylococcus capsulatus and Methylosinus trichosporium, is cultivated in a culture medium in contact with gas containing methane which is the main source of carbon, to allow the L-amino acid to be produced and accumulated in the medium, and the L-amino acid is collected from the medium.
Claims12
A method for production of an L-amino acid, comprising the steps of:
- cultivating a methane-utilizing microorganism capable of producing L-amino acid in a culture medium which is in contact with gas containing methane which is the main source of carbon, to allow said L-amino acid to be produced and accumulated in said medium, and collecting said L-amino acid from said medium.
A mutant strain of a methane-utilizing microorganism capable of producing L-amino acid and resistant to the an L-amino acid or an analog thereof.
A transformant of a mthane-utilizing microorganism capable of producing L-amino acid which harbors a vector capable of encoding at least one enzyme involved in biosynthesis of L-amino acid.
