摘要

Bordetella sp. HZ20 was isolated from the surface of brown seaweed (Laminaria japonica) and absence of the abilities to decompose the brown seaweed. The genome of Bordetella sp. HZ20 was sequenced and comprised of one circular chromosome with the size of 4,227,194 bp and DNA G + C content of 55.5%. Genomic annotation showed that, Bordetella sp. HZ20 may have chitin degradation related enzymes, heparin-sulfate lyase-like protein and enzymes related to the synthase and utilization of polyhydroxyalkanoate for carbon utilization, nitrate and nitrite reductase, glutamate dehydrogenase, glutamate synthase and glutamine synthetase for nitrogen cycle, polyphosphate kinases (pkkl and pkk2), the high-affinity phosphate-specific transport (Pst) system and the low-affinity inorganic phosphate transporter (pitA) for phosphorus cycle, cysteine synthase and type III acyl coenzyme A transferase (dddD) for sulfur cycle. These features indicated the metabolic patterns of Bordetella sp. HZ20 in C, N, P and S cycles. In addition, the predicted Pst system and cysteine synthase were also related to biofilm formation which showed the potential pathogenicity of Bordetella sp. HZ20 to the cells of animals or plants. This study provides evidences about the metabolic patterns of Bordetella sp. HZ20 and broadens our understandings about ecological roles of bacterium without algal-polysaccharides degrading abilities in the brown seaweed-abundant environment.
