Draft Genome Sequence of Ureolytic Environmental Isolate Bacillus galactosidilyticus PL133

Area of Science:

• Microbiology
• Genomics
• Environmental Science

Background:

• Poultry litter generates ammonia, impacting air quality and nutrient cycling.
• Cultivable aerobic bacteria play roles in decomposition processes within agricultural waste.
• Ureolytic activity is a key microbial function linked to ammonia production.

Purpose of the Study:

• To present the draft genome sequence of Bacillus galactosidilyticus PL133.
• To characterize the ureolytic potential of this bacterium isolated from poultry litter.

Main Methods:

• Whole-genome sequencing was performed to generate a 5.19-Mb draft genome.
• Bacterial isolation and identification from poultry litter samples.
• Assay of ureolytic activity.

Main Results:

• A 5.19-megabase (Mb) draft genome sequence for Bacillus galactosidilyticus PL133 was successfully obtained.
• The isolate was confirmed as a significant cultivable aerobic bacterium.
• Demonstrated ureolytic activity, confirming its role in ammonia generation.

Conclusions:

• The genome sequence provides a foundation for understanding Bacillus galactosidilyticus PL133.
• This bacterium is a key player in the microbial community of poultry litter.
• Its ureolytic function is critical for ammonia release from poultry residue.
