Genome Sequences of Microbacterium foliorum Phages Anseraureola, Pondwater, and Yasuo

Area of Science:

• Microbiology
• Virology
• Genomics

Background:

• Bacteriophages are viruses that infect bacteria.
• Microbacterium foliorum is a bacterial species found in various environments.
• Siphovirus morphology is common among bacteriophages.

Purpose of the Study:

• To isolate and characterize novel bacteriophages targeting Microbacterium foliorum NRRL B-24224.
• To determine the genomic features and taxonomic placement of newly discovered phages.

Main Methods:

• Isolation of bacteriophages from soil samples.
• Electron microscopy for morphological characterization (siphovirus).
• Genome sequencing and analysis to determine genome size and gene content.
• Phylogenetic analysis for phage clustering (phage cluster EE).

Main Results:

• Isolation of three distinct bacteriophages: Anseraureola, Pondwater, and Yasuo.
• All three phages exhibit siphovirus morphology.
• Genome lengths range from 17,362 to 17,453 base pairs.
• Each phage genome contains 25 predicted protein-coding genes.
• Phages are assigned to the EE phage cluster.

Conclusions:

• Anseraureola, Pondwater, and Yasuo represent newly identified bacteriophages infecting Microbacterium foliorum.
• These siphoviruses share conserved genomic characteristics and belong to phage cluster EE.
• The findings contribute to the understanding of phage diversity and host specificity.
