Genome-guided prediction of acid resistance mechanisms in acidophilic methanotrophs of phylogenetically deep-rooted Verrucomicrobia isolated from geothermal environments

Autor: Gonzalo Neira, Eva Vergara, David S. Holmes

Publikováno v: Frontiers in Microbiology, Vol 13 (2022)

Verrucomicrobia are a group of microorganisms that have been proposed to be deeply rooted in the Tree of Life. Some are methanotrophs that oxidize the potent greenhouse gas methane and are thus important in decreasing atmospheric concentrations of th

Prediction and Inferred Evolution of Acid Tolerance Genes in the Biotechnologically Important Acidihalobacter Genus

Autor: Katelyn Boase, Carolina González, Eva Vergara, Gonzalo Neira, David Holmes, Elizabeth Watkin

Publikováno v: Frontiers in Microbiology, Vol 13 (2022)

Acidihalobacter is a genus of acidophilic, gram-negative bacteria known for its ability to oxidize pyrite minerals in the presence of elevated chloride ions, a capability rare in other iron-sulfur oxidizing acidophiles. Previous research involving Ac

A Large-Scale Genome-Based Survey of Acidophilic Bacteria Suggests That Genome Streamlining Is an Adaption for Life at Low pH

Autor: Diego Cortez, Gonzalo Neira, Carolina González, Eva Vergara, David S. Holmes

Publikováno v: Frontiers in Microbiology, Vol 13 (2022)

The genome streamlining theory suggests that reduction of microbial genome size optimizes energy utilization in stressful environments. Although this hypothesis has been explored in several cases of low-nutrient (oligotrophic) and high-temperature en

A Large-Scale Multiple Genome Comparison of Acidophilic Archaea (pH ≤ 5.0) Extends Our Understanding of Oxidative Stress Responses in Polyextreme Environments

Autor: Gonzalo Neira, Eva Vergara, Diego Cortez, David S. Holmes

Publikováno v: Antioxidants, Vol 11, Iss 1, p 59 (2021)

Acidophilic archaea thrive in anaerobic and aerobic low pH environments (pH < 5) rich in dissolved heavy metals that exacerbate stress caused by the production of reactive oxygen species (ROS) such as hydrogen peroxide (H2O2), hydroxyl radical (·OH)

A large scale, multiple genome comparison of acidophilic Archaea (pH ≤ 5.0) extends our understanding of oxidative stress responses in polyextreme environments

Autor: Eva Vergara, David S. Holmes, Diego Cortez, Gonzalo Neira

Acidophilic Archaea thrive in anaerobic and aerobic low pH environments (2O2), hydroxyl radical (•OH) and superoxide (O2•−). ROS react with lipids, proteins and nucleic acids causing oxidative stress and damage that can lead to cell death. Here
