CRISPR research began over 30 years ago with the incidental discovery of an unusual nucleotide arrangement in the Escherichia coli genome. It took 20 years to find the main function of CRISPR-Cas systems as an adaptive defence mechanism against invading nucleic acids, and our knowledge of their biology has steadily increased ever since. In parallel...

Understanding the pathogenesis of certain viral agents is essential for developing new treatments and obtaining a clinical cure. With the onset of the new coronavirus (SARS-CoV-2) pandemic in the beginning of 2020, a rush to conduct studies and develop drugs has led to the publication of articles that seek to address knowledge gaps and contribute t...

Hot Lake is a small heliothermal and hypersaline lake in far north-central Washington State (USA) and is limnologically unusual because MgSO4 rather than NaCl is the dominant salt. In late summer, the Hot Lake metalimnion becomes distinctly green from blooms of planktonic phototrophs. In a study undertaken over 60 years ago, these blooms were predi...

The enormous spread of Staphylococcus aureus infections through biofilms is a major concern in hospital-acquired infections. Biofilm formation by S. aureus on any surface is facilitated by adjusting its redox status. This organism is a facultative anaerobe shifts more towards reductive conditions by enhancing nitrogen metabolism where Glutamine syn...

The ongoing coronavirus disease 2019 (COVID-19) pandemic is a rapidly evolving situation. New discoveries about COVID-19 and its causative virus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), continue to deepen the understanding of this novel disease. As there is currently no COVID-19 specific treatment, isolation is the most effect...

The bacteria can establish beneficial interactions with plants acting as growth promoters and enhance stress tolerance during plant interactions. Likewise, bacteria are able to develop multi-species communities where multiple interactions are possible. In this work, we assessed the physiological effects of three bacteria isolated from an arid envir...

Brewer's yeast has been widely used in the food industry, and the autolysates thereof are increasingly being studied for their valuable nutritional compositions. Yeast autolysis is most affected by medium composition and temperature. In this study, a thermosensitive autolytic brewer's yeast P-510 was obtained with atmospheric and room temperature p...

The gut microbiome encompasses trillions of residing microbes, mainly bacteria, which play a crucial role in maintaining the physiological and metabolic health of the host. The gut microbiome has been associated with several diseases, including cardiovascular disease (CVD). A growing body of evidence suggests that an altered gut environment and gut...

The ability for a soybean plant to be efficiently nodulated when grown as a crop is dependent on the number of effective Bradyrhizobium japonicum that can be found in close proximity to the developing seedling shortly after planting. In Manitoba, the growing of soybean as a crop has increased from less than 500,000 acres in 2008 to over 2.3 million...

Jacquinia macrocarpa, a plant native to northwestern Mexico, has an inhibitory effect against phytopathogenic fungi. Previous studies have shown that the butanolic extract of J. macrocarpa causes retardation and atrophy in mycelial growth of Fusarium verticillioides. However, the action mechanism of this extract is unknown. We used a proteomics app...
