2 days ago · Staphylococcus aureus is a gram-positive spherically shaped bacterium, a member of the Bacillota, and is a usual member of the microbiota of the body, frequently found in the upper respiratory tract and on the skin. It is often positive for catalase and nitrate reduction and is a facultative anaerobe that can grow without the need for oxygen.
6 days ago · Gut microbiota, gut microbiome, or gut flora are the microorganisms, including bacteria, archaea, fungi, and viruses, that live in the digestive tracts of animals. [1] [2] The gastrointestinal metagenome is the aggregate of all the genomes of the gut microbiota. [3] [4] The gut is the main location of the human microbiome. [5]
2 days ago · They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust.
May 23, 2024 · A higher relative abundance was observed for Bacillota (Weisella, Veillonella, Allisonella, Acidaminococcus, Catenibacterium, and Streptococcus) ...
May 11, 2024 · The relative abundance of the Bacillota class Clostridia more than doubled in the 0–5 cm agricultural soils relative to the forest soils. At both depths two Actinomycetota classes (Acidimicrobiia, MB.A2.108) decreased in relative abundance after conversion to agriculture, while two Gemmatimonadota classes (Gemmatimonadetes, Gemm.1) increased ...
May 17, 2024 · The soil microbial community was dominated by Bacillota after glucose addition. • The ratio of heat to CO 2 release during growth showed a pronounced temporal pattern. • A dynamic model suggests a transition to anaerobiosis as the cause of this pattern. • Anaerobic pathways like fermentations are also consistent with Bacillota dominance.
May 3, 2024 · These enzyme structures are most similar to an α-L-fucosidase synthesised by a Bacillota species. However, protein–protein blast results revealed the highest sequence coverage for Bacteroidota ...
