Carbon monoxide can improve the effectiveness of antibiotics, making bacteria more sensitive to antibiotic medication, according to a study led by Georgia State University.
Researchers at Duke University have created a framework for helping bioengineers determine when to use multiple lines of cells to manufacture a product. The work could help a variety of industries that use bacteria to produce chemicals ranging from pharmaceuticals to fragrances.
A team of scientists, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has unveiled that the bacterium Chromobacterium piscinae produces cyanide, an inhibitory molecule, to defend themselves in the battle against Bdellovibrio bacteriovorus HD100.
The bacterium Streptomyces chartreusis is an antibiotic-producing bacterium that releases more metabolites into the surrounding medium than scientists assumed based on the analysis of the genome. Many of the substances are likely released to mediate interactions with its environment. They might also include molecules that are of interest as potential pharmaceutical agents. A research team analysed a broad spectrum of the bacterium's metabolic products under various culture conditions.
Attack at the protein front: Xanthomonas bacteria cause diseases in tomato and pepper plants and inject harmful proteins into plant cells. Researchers from Martin Luther University Halle-Wittenberg (MLU), the University of Bonn, the University of Freiburg and the Leibniz Institute of Plant Biochemistry (IPB) in Halle have now discovered how one of these proteins manipulates the nutrient supply and hormonal balance of plants. Their study was recently published in the renowned journal "Nature Communications".
Sipping wine is good for your colon and heart, possibly because of the beverage's abundant and structurally diverse polyphenols. Now researchers report in ACS' Journal of Agricultural and Food Chemistry that wine polyphenols might also be good for your oral health.
Bacteria-killing viruses could be employed not just in health care, but also in the food industry, a study conducted at the University of Helsinki indicates. The researchers have been investigating the possibility of utilising phages in eradicating foodborne pathogens and preventing food poisoning
A team of American Museum of Natural History researchers has created a computational model capable of predicting whether or not organisms have the ability to 'eat' other cells through a process known as phagocytosis. The model may be a useful tool for large-scale microbe surveys and provides valuable insight into the evolution of complex life on Earth, challenging ideas put forward in recent studies.
Researchers at Stanford are studying how bacteria living in the gut respond to common changes within their habitat, working with mice. They change the gut environment within the mice, and then measure which bacterial species survive the change and how the gut environment itself has changed. They also study the physiological response of the bacteria -- if they grow faster or slower, or produce different proteins. The work was presented during the Biophysical Society Meeting.
Bacteria play a major role in cleaning up oil spills and mitigating its environmental impacts. In a review published in Science of the Total Environment, researchers from Aarhus University, Denmark, examine the major limiting factors for microbial degradation in Arctic environments.
