Aquatic ecosystems around the world are contaminated with a wide range of anthropogenic
chemicals, including metals and organic pollutants, that originate from point and nonpoint …

The ability of Staphylococcus aureus to infect many different tissue sites is enabled, in part,
by its transcriptional regulatory network (TRN) that coordinates its gene expression to …

Evolution fine-tunes biological pathways to achieve a robust cellular physiology. Two and a
half billion years ago, rapidly rising levels of oxygen as a byproduct of blooming …

Oxidative stress is concomitant with aerobic metabolism. Thus, bacterial genomes encode
elaborate mechanisms to achieve redox homeostasis. Here we report that the peroxide-…

The bacterial respiratory electron transport system (ETS) is branched to allow condition-specific
modulation of energy metabolism. There is a detailed understanding of the structural …

The ability of Escherichia coli to tolerate acid stress is important for its survival and colonization
in the human digestive tract. Here, we performed adaptive laboratory evolution of the …

Relationships between the genome, transcriptome, and metabolome underlie all evolved
phenotypes. However, it has proved difficult to elucidate these relationships because of the …

Soils account for the largest global mercury reservoirs, but observations are sparse in many
regions. The accumulation and turnover of mercury in soils determines whether they act as …

Although the use of ionic liquids (ILs) for the pretreatment of lignocellulosic biomass has
been limited due to high costs, recent efforts to develop low-cost protic ILs show promise for …

Mercury is a global pollutant whose supply to the environment has greatly increased due to
human activities resulting in adverse effects on human and wildlife health. In response, the …
