Objective

To mine the bioinformation of Serratia marcescens HBQT and analyze its characteristics.

Methods

The selenium enrichment capacity of Serratia marcescens HBQT was evaluated. High-throughput whole-genome sequencing and bioinformatics analysis were performed. Its antibacterial activity against Staphylococcus aureus and Listeria monocytogenes, as well as its growth-promoting effect on mung bean sprouts, were determined. Additionally, changes in the strain’s susceptibility to drugs such as ceftazidime, biofilm growth and antioxidant capacity were measured before and after selenite treatment.

Results

Within 48 hours, Serratia marcescens HBQT was able to convert 99% of the selenite at a concentration of 3 mmol/L. The complete genome length was 5117438 bp, with a guanine-cytosine content of 59.51%, and it contained one circular plasmid.Bioinformatics analysis revealed enrichment of genes related to sulfur metabolism and active transport. The strain significantly inhibited the growth of Staphylococcus aureus and Listeria monocytogenes (P<0.001) and markedly promoted the growth of mung bean sprouts (P<0.001). After selenite treatment, the strain’s antagonistic ability against ceftazidime, biofilm formation capacity and antioxidant capacity were significantly enhanced (P<0.001).

Conclusion

Serratia marcescens HBQT exhibits promising biocontrol and plant growth-promoting characteristics.The whole-genome analysis and phenotypic changes after selenium enrichment lay the foundation for elucidating the molecular mechanisms by which bacteria antagonize selenite toxicity and generate selenium nanoparticles.
