Temperature is one of the most important factors for bacterial growth and development. Cold environments are widely distributed on earth, psychrotolerant psychrophilic microorganisms have developed different adaptation strategies to cope with stress derived from low temperatures. Pseudomonas extremaustralis an Antarctic bacterium able grow under temperatures produce high amounts polyhydroxyalkanoates (PHAs). In this work, we analyzed genome-wide transcriptome by RNA deep-sequencing...
Staphylococcus aureus (SA) and Pseudomonas aeruginosa (PA) cause a wide variety of bacterial infections coinfections, showing complex interaction that involves the production different metabolites metabolic changes. Temperature is key factor for survival virulence within host, bacteria could be exposed to an increment in temperature during fever development. We analyzed previously unexplored effect fever-like temperatures (39 °C) on S. USA300 P. PAO1 microaerobic mono- co-cultures compared...
Psychrotroph microorganisms have developed cellular mechanisms to cope with cold stress. Cell envelopes are key components for bacterial survival. Outer membrane is a constituent of Gram negative envelopes, consisting several components, such as lipopolysaccharides (LPS). In this work we investigated the relevance envelope characteristics adaptation in Antarctic bacterium Pseudomonas extremaustralis by analyzing mini Tn5 wapH mutant strain, encoding core LPS glycosyltransferase. Our results...
Bacteria are exposed to reactive oxygen and nitrogen species that provoke oxidative nitrosative stress which can lead macromolecule damage. Coping with conditions involves the adjustment of cellular responses, helps address metabolic challenges. In this study, we performed a global transcriptomic analysis response Pseudomonas extremaustralis stress, induced by S-nitrosoglutathione (GSNO), nitric oxide donor, under microaerobic conditions. The revealed upregulation genes associated inositol...
Bacterial small non-coding RNAs (sRNAs) play key roles as genetic regulators, mediating in the adaptability to changing environmental conditions and stress responses. In this work, we analysed putative sRNAs identified by RNA-seq experiments different aeration extremophile bacterium P. extremaustralis. These analyses allowed identification of 177 under aerobiosis (A), microaerobiosis (M) after H2 O2 exposure (m-OS). The size transcription profile eight with differential expression were...
