Aspergillus niger Spores Are Highly Resistant to Space Radiation [PDF]

Frontiers in Microbiology, 2020
The filamentous fungus Aspergillus niger is one of the main contaminants of the International Space Station (ISS). It forms highly pigmented, airborne spores that have thick cell walls and low metabolic activity, enabling them to withstand harsh ...

Electrochemical potential enables dormant spores to integrate environmental signals

Science, 2022
The dormant state of bacterial spores is generally thought to be devoid of biological activity. We show that despite continued dormancy, spores can integrate environmental signals over time through a preexisting electrochemical potential.

Entry of spores into intestinal epithelial cells contributes to recurrence of Clostridioides difficile infection

Nature Communications, 2021
Clostridioides difficile spores produced during infection are important for the recurrence of the disease. Here, we show that C. difficile spores gain entry into the intestinal mucosa via pathways dependent on host fibronectin-α5β1 and vitronectin-αvβ1 ...

Bacillus spores: a review of their properties and inactivation processing technologies

Food Science and Biotechnology, 2020
Many factors determine the resistance properties of a Bacillus spore to heat, chemical and physical processing, including thick proteinaceous coats, peptidoglycan cortex and low water content, high levels of dipicolinic acid (DPA), and divalent cations ...

Sporulation conditions influence the surface and adhesion properties of Bacillus subtilis spores

Frontiers in Microbiology, 2023
Spore-forming bacteria of the Bacillus subtilis group are responsible for recurrent contamination of processing lines in the food industry which can lead to food spoilage. The persistence of B.

DNA Damage Kills Bacterial Spores and Cells Exposed to 222-Nanometer UV Radiation

Applied and Environmental Microbiology, 2020
Spores of a variety of bacteria are resistant to common decontamination agents, and many of them are major causes of food spoilage and some serious human diseases, including anthrax caused by spores of Bacillus anthracis.

Resilient living materials built by printing bacterial spores

bioRxiv, 2019
Materials can be made multifunctional by embedding them with living cells that perform sensing, synthesis, energy production, and physical movement. A challenge is that the conditions needed for living cells are not conducive to materials processing and ...

Characterization of Lung Inflammatory Response to Aspergillus fumigatus Spores

Journal of Fungi, 2023
The airway exposure to Aspergillus fumigatus spores (AFsp) is associated with an inflammatory response, potentially leading to allergic and/or chronic pulmonary aspergillosis. The aim of our study is to better understand the host response, first in vitro,
