Phosphate limitation induces the intergeneric inhibition of Pseudomonas aeruginosa by Serratia marcescens isolated from paper machines
Phosphate is an essential nutrient for heterotrophic bacteria, affecting bacterioplankton in aquatic ecosystems and bacteria in biofilms. However, the influence of phosphate limitation on bacterial competition and biofilm development in multispecies populations has received limited attention in existing studies. To address this issue, we isolated 13 adhesive bacteria from paper machine aggregat...
متن کاملBiosynthesis of prodigiosin, a secondary metabolite of Serratia marcescens.
Prodigiosenes (prodigiosin and prodigiosin-like pigments) are known to be synthesized by only one genus of Eubacteriales and by two genera of Actinomycetales. Biosynthesis by Serratia marcescens occurs over a relatively narrow range of temperatures, although the bacteria grow over a broad range. When cultures of S. marcescens were incubated at 27 C in 1.0% casein hydrolysate, viable count and p...
متن کاملSerratia marcescens.
Over the last 30 years, Serratia marcescens has become an important cause of nosocomial infection. There have been many reports concerning the identification, antibiotic susceptibility, pathogenicity, epidemiological investigations and typing of this organism. Accurate identification is important in defining outbreaks. The API 20E system has been used widely, but is not individually satisfactor...
متن کاملSerratia marcescens
The nucleotide sequence of the proBA operon from a proline-hyperproducing mutant of Serratia marcescens was determined. Two base substitutions were found: one in theproBstructura1 gene, coding for y-glutamyl kinase (GK), and a second one in the promoter region of the operon. The former base substitution led to a change of the predicted amino acid at position 117 from an alanine to a valine in G...
متن کاملSerratia marcescens meningitis.
A case of Serratia marcescens meningitis in a 66-year-old man is reported. The infection occurred 4 weeks after apparently successful otic surgery, and a nidus of infection in the middle ear was established at autopsy. This is the second case of S. marcescens meningitis following ear surgery reported in the English-language literature.
