Persisters show heritable phenotype and generate bacterial heterogeneity and noise in protein expression [PDF]

, 2009
Persisters are a small subpopulation of bacteria that survive a lethal concentration of antibiotic without antibiotic resistance genes. Isolation of persisters from normally dividing population is considered difficult due to their slow growth, low ...

Pyrite oxidation under initially neutral pH conditions and in the presence of Acidithiobacillus ferrooxidans and micromolar hydrogen peroxide [PDF]

, 2012
Hydrogen peroxide (H2O2) at a micromolar level played a role in the microbial surface oxidation of pyrite crystals under initially neutral pH. When the mineral-bacteria system was cyclically exposed to 50 μM H2O2, the colonization of Acidithiobacillus ...
