Bacillus paranthracis
Genomic DNA was extracted from a pure culture of *Bacillus paranthracis* strain S23 using a commercial bacterial genomic DNA extraction kit according to the manufacturer's instructions. DNA quality and concentration were assessed using spectrophotometry and agarose gel electrophoresis. A paired-end sequencing library was prepared using the Illumina DNA Prep (Nextera DNA Flex) library preparation kit following the manufacturer's protocol. The library was sequenced on an Illumina platform to generate 2  150 bp paired-end reads. Raw sequencing reads were subjected to quality assessment and adapter trimming prior to de novo genome assembly.
