Bacillus licheniformis is an important bacterium that has been used extensively for large-scale industrial production of exoen-
zymes and peptide antibiotics. B. licheniformis WX-02 produces poly-gamma-glutamate increasingly when fermented under
is used to produce enzymatic agents (12), peptide antibiotics (7),
acetoin (8), and poly-?-glutamic acid (?-PGA) (1, 2), etc. B. li-
cheniformis WX-02 was isolated from saline soil in Yingcheng
produce larger amounts of ?-PGA under stress conditions than
under normal ones; the stresses refer to high salt, high tempera-
ture, caustic alkali, ultrasonic shock, and so on. The yield of
?-PGA can be raised 5.28 times against that of the control group
when the salt concentration reaches 8% (13). In order to explore
the mechanism of high production of ?-PGA under adverse cir-
licheniformis WX-02 has been maintained at the China Center for
Type Culture Collection and designated B. licheniformis CCTCC
Whole-genome sequencing was performed using a Solexa
genome analyzer (BGI; Shenzhen, China) using a shotgun
strategy, which produced paired reads totaling ?555 Mb with
were processed and assembled into 45 contigs and 29 scaffolds
(5). Gaps between contigs were closed by combinatorial PCR
and sequencing amplicons by primer walking. Finally, this as-
sembling process produced 3 large scaffolds in one potential
circular chromosome. Open reading frames were identified using
&group?programs&subgroup?gfindb), Prodigal (http://compbio
.ornl.gov/prodigal/), and Glimmer (http://www.ncbi.nlm.nih.gov
/genomes/MICROBES/glimmer_3.cgi) and BLAST against the Ref-
Seq database. tRNA and rRNA genes were identified by the
tRNAScan and RNAmmer software programs, respectively (4, 6).
The genome of strain CCTCC M208065 is 4,270,104 bp long with a
GC content of 46.06%, containing 4,320 open reading frames, 72
M208065 shares great similarity (94.8%) with that of ATCC 14580,
about 76 kb in this genome sharing very low homology with the
ment encodes the DNA replication initiator protein, conjugation
protein, RNA polymerase sigma factors, transcriptional regulators,
acillus licheniformis is a Gram-positive bacterium which in-
in regulation of ?-PGA synthesis (3, 11). The comP gene in the
ATCC 14580 strain is inactivated by two insertional fragments,
the comP gene between these two strains might be associated with
idence is needed to verify this.
