Discovery NotesThe phage is discovered from the suface soil.In January , we collected soil samples and discovered a new bacteriophage from it. There was no snow covering the soil.
Naming NotesPhage named "Nonchalant". It wishes the researchers can do the research in calm and without worry.

Genome length (bp)Unknown
Character of genome endsUnknown
Fasta file available?No
Characterization
ClusterUnclustered
Subcluster--
Lysogeny NotesNo evidence of lysogeny was observed in phage Nonchalant. During host range and stress condition testing, the phage showed:

No growth (no plaques) on Gordonia rubi, a non-permissive host.

No growth after exposure to harsh environments (pH = 2 and 100 °C), indicating that the phage was inactivated rather than entering a lysogenic state.

Clear plaques on M. smegmatis ATCC 607 with an EOP > 1, suggesting strong lytic activity.

Nonchalant appears to be a strictly lytic phage under current lab conditions.
