Evolving strategies for single-celled organisms in multi-nutrient environments [PDF]
, 2015 When micro-organisms are in environments with multiple nutrients, they often preferentially utilise one first. A second is only utilised once the first is exhausted. Such a two-phase growth pattern is known as diauxic growth.

Multiple facets of bacterial porins [PDF]
FEMS Microbiology Letters, 2001 Porins form channels allowing the transport of molecules across lipid bilayer membranes. Their structure, location and large number on the bacterial surface lend them multiple functions. Porin loops are potential targets for adhesion to other cells and binding of bactericidal compounds to the surface of Gram-negative bacteria.

Quantification of Fluoroquinolone Uptake through the Outer Membrane Channel OmpF of Escherichia coli. [PDF]
, 2015 Decreased drug accumulation is a common cause of antibiotic resistance in microorganisms. However, there are few reliable general techniques capable of quantifying drug uptake through bacterial membranes.

Evolving Biological Systems: Evolutionary Pressure to Inefficiency [PDF]
, 2014 The evolution of quantitative details (i.e. “parameter values”) of biological systems is highly under-researched. We use evolutionary algorithms to co-evolve parameters for a generic but biologically plausible topological differential equation model of ...

Asymmetric conductivity of engineered porins [PDF]
Protein Engineering, Design and Selection, 2002 Positively charged peptide segments of 16 and 18 residues were inserted at a periplasmic turn of the porin from Rhodobacter blasticus in order to form an electric field-dependent plug. The X-ray diffraction analysis of a mutant confirmed that the structure of the porin had remained intact and that the insert was mobile.

Fluoroquinolone-Transition Metal Complexes: A Strategy to Overcome Bacterial Resistance
Microorganisms, 2021 Fluoroquinolones (FQs) are antibiotics widely used in the clinical practice due to their large spectrum of action against Gram-negative and some Gram-positive bacteria.

The pio Operon Is Essential for Phototrophic Fe(II) Oxidation in Rhodopseudomonas palustris TIE-1 [PDF]
, 2006 Phototrophic Fe(II)-oxidizing bacteria couple the oxidation of ferrous iron [Fe(II)] to reductive CO2 fixation by using light energy, but until recently, little has been understood about the molecular basis for this process. Here we report the discovery,

Socialization of Providencia stuartii Enables Resistance to Environmental Insults
Microorganisms, 2022 Providencia stuartii is a highly social pathogen responsible for nosocomial chronic urinary tract infections. The bacterium indeed forms floating communities of cells (FCC) besides and prior-to canonical surface-attached biofilms (SAB).
