Microbiology

Definition

Microbiology is the study of microscopic organisms, such as bacteria, viruses, archaea, fungi and protozoa. This discipline includes fundamental research on the biochemistry, physiology, cell biology, ecology, evolution and clinical aspects of microorganisms, including the host response to these agents.

    A pure culture of the complete nitrifier Nitrospira inopinata shows a high affinity for ammonia, low maximum rate of ammonia oxidation, high growth yield compared to canonical nitrifiers and genomic potential for alternative metabolisms, probably reflecting an important role in nitrification in oligotrophic environments.

    Measurements from Antarctic ice suggest that geological methane emissions are much lower than previously thought, and that methane emissions from hydrates and permafrost in response to climate warming are minimal.

    Direct-acting antiviral agents (DAAs) are highly effective treatments for HCV, but are not always accessible to people who inject drugs (PWID). Here, Grebely and colleagues outline the epidemiology of HCV in PWID, discuss current data on DAA outcomes in this population and highlight steps required to broaden access to HCV therapy with the eventual goal of HCV elimination.

    Most bacteria live in biofilms, surface-attached communities encased in an extracellular matrix. Here, Yan et al. show that matrix production in Vibrio cholerae increases the osmotic pressure within the biofilm, promoting biofilm expansion and physical exclusion of non-matrix producing cheaters.

    Estimates of the carbon content of Earth’s mantle and magmas vary. Analysis and modelling of gas emissions at Hawai‘i indicate that the amount of carbon in the Hawaiian mantle plume and CO2 in Hawaiian lavas is 40% greater than previously thought.
