1. A method of reducing the amount of at least one tobacco-specific nitrosamine (TSNA) in a composition comprising tobacco, comprising contacting said composition with an isolated bacterial strain of Myroides odoratus comprising a 16S rDNA sequence at least 98% identical to SEQ ID NO: 1 under conditions in which the amount of said at least one TSNA is reduced in said composition, wherein said conditions comprise (a) a moisture content from about 45% to about 75% by weight of said tobacco; (b) a temperature from about 20° C. to about 45° C.; (c) a pH of about 5 to about 8; or (d) any combination of (a), (b), and (c), thereby producing a reduced-TSNA composition.
