2. 1. Encounters at the microscale: Unraveling soil microbial interactions with nanoplastics

   Author : P. Micaela Mafla-Endara; MEMEG; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microfluidic devices; Nanoplastics; Soil microorganisms; Toxicity;

   Abstract : Nanoplastics (NPs) originated from plastic residues can interact with soil microorganisms with potential negative effects to their functions. Therefore, I aimed to investigate soil microbial population dynamics when exposed to different NP polymers and concentrations. READ MORE

4. 2. Multiple regulatory inputs for hierarchical control of phenol catabolism by Pseudomonas putida

   Author : W. K. Anjana Madhushani; Victoria Shingler; Livia Leoni; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; P. putida; Phenol catabolism; dmpR; dmp-System; 5’-LR; Carbon Catabolite Repression; Transcriptional Translational regulation; Crc; CrcZ; CrcY; Hfq;

   Abstract : Metabolically versatile bacteria have evolved diverse strategies to adapt to different environmental niches and respond to fluctuating physico-chemical parameters. In order to survive in soil and water habitats, they employ specific and global regulatory circuits to integrate external and internal signals to counteract stress and optimise their energy status.

5. 3. Metabolism-dependent taxis and control of motility in Pseudomonas putida

   Author : Sofia Österberg; Vicky Shingler; Caroline Harwood; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Motility; c-di-GMP; metabolism-dependent taxis; receptors; transcription; Pseudomonas putida; molekylärbiologi; Molecular Biology;

   Abstract : Bacteria living in soil and aquatic habitats rapidly adapt to changes in physico-chemical parameters that influence their energy status and thus their ability to proliferate and survive. One immediate survival strategy is to relocate to more metabolically optimal environments. READ MORE

6. 4. Deciphering control of Mechano-Transcription Activators of σ54-RNA polymerase

   Author : Henrik Seibt; Victoria Shingler; Uwe H. Sauer; Ray Dixon; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transcriptional regulation; P. putida; V. cholerae; AAA ; bEBP; B-linker; DmpR; Phenol catabolism; VCA0117; Type VI secretion; molekylärbiologi; Molecular Biology;

   Abstract : To survive and proliferate, bacteria have to respond to a plethora of fluctuating signals within their habitats. Transcriptional control is one crucial entry point for such signal-responsive adaption responses. READ MORE

7. 5. On the role of ppGpp and DksA mediated control of σ54-dependent transcription

   Author : Lisandro Bernardo; Victoria Shingler; Victor de Lorenzo; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ppGpp; DksA; σ54-transcription; global regulation; E. coli; P. putida; Molecular biology; Molekylärbiologi;

   Abstract : The σ54-dependent Po promoter drives transcription of an operon that encodes a suite of enzymes for (methyl)phenols catabolism. Transcription from Po is controlled by the sensor-activator DmpR that binds (methyl)phenol effectors to take up its active form. READ MORE
