Bacteriophage and methods of making and using
Bacteriophage are provided, and methods of making and using the bacteriophage also are provided.
1. A method for reducing the level of tobacco-specific nitrosamines (TSNAs) in tobacco, comprising:
contacting tobacco with an effective amount of a composition comprising:
a bacteriophage comprising a nucleic acid sequence encoding an endolysin, wherein the nucleic acid sequence has at least 95% sequence identity to the nucleic acid sequence shown in SEQ ID NO: 1; or
a bacteriophage comprising a nucleic acid sequence encoding an endolysin having at least 95% sequence identity to the amino acid sequence shown in SEQ ID NO: 2.
2. The method of claim 1 , wherein the tobacco is contacted with the composition comprising the bacteriophage prior to fermentation of the tobacco.
3. An aged and cured tobacco comprising one or more bacteriophages, wherein the bacteriophage is selected from the group consisting of
a bacteriophage comprising a nucleic acid sequence encoding an endolysin, wherein the nucleic acid sequence has at least 95% sequence identity to the nucleic acid sequence shown in SEQ ID NO: 1; and
a bacteriophage comprising a nucleic acid sequence encoding an endolysin having at least 95% sequence identity to the amino acid sequence shown in SEP ID NO: 2.
4. A smokeless tobacco product comprising a tobacco comprising one or more bacteriophages, wherein the bacteriophage is selected from the group consisting of
a bacteriophage comprising a nucleic acid sequence encoding an endolysin, wherein the nucleic acid sequence has at least 95% sequence identity to the nucleic acid sequence shown in SEQ ID NO: 1; and
a bacteriophage comprising a nucleic acid sequence encoding an endolysin having at least 95% sequence identity to the amino acid sequence shown in SEP ID NO: 2.
5. A cigarette comprising a tobacco comprising one or more bacteriophages, wherein the bacteriophage is selected from the group consisting of
a bacteriophage comprising a nucleic acid sequence encoding an endolysin, wherein the nucleic acid sequence has at least 95% sequence identity to the nucleic acid sequence shown in SEQ ID NO: 1; and
a bacteriophage comprising a nucleic acid sequence encoding an endolysin having at least 95% sequence identity to the amino acid sequence shown in SEQ ID NO: 2.
