Bacillus subtilis (/ b ə ˈ s ɪ l. ə s s u b ˈ t iː. l i s /), [3] [4] known also as the hay bacillus or grass bacillus, is a gram-positive, catalase-positive bacterium, found in soil and the gastrointestinal tract of ruminants, humans and marine sponges.

Oct 15, 2020 · Bacillus subtilis, hay bacillus, or grass bacillus was one of the first Gram-positive bacteria to be studied. It is an aerobic, rod-shaped spore-forming microorganism that can spread in extreme cold, heat, and even disinfected environments.

Bacillus subtilis (B. subtilis) is a type of probiotic ("good" bacteria) found naturally in the human gut. It's also found in fermented foods.

Bacillus subtilis is the best studied model organism of the Gram-positive lineage. It is naturally transformable and has an extremely powerful genetic toolbox. It is fast growing and easy to cultivate.

Jul 7, 2022 · Bacillus subtilis is a Gram-positive, rod-shaped bacterium that is the type species of the genus Bacillus, commonly used as a model organism to describe the structure of different species of the genus.

Bacillus subtilis is a Gram positive, facultative aerobic bacterium which is a well characterized work horse in fundamental research and biotechnological processes.

Next to Escherichia coli, Bacillus subtilis is the most studied and best understood organism that also serves as a model for many important pathogens. Due to its ability to form heat-resistant spores that can germinate even after very long periods ...

Jan 27, 2025 · 1. Introduction. The bacterium, Bacillus subtilis which is well-known as soil-dwelling prokaryote, was discovered by Christian Gottfried Ehrenberg [].It is a Gram-positive bacterium with rod-shaped cells, 2–6 μm in length and less than 1 μm in diameter. The organism has a single circular chromosome of 4.2 million base pairs long, encoding 4100 genes [].

Bacillus subtilis is a remarkably diverse bacterial species that is capable of growth within many environments. Recent microarray-based comparative genomic analyses have revealed that members of this species also exhibit considerable genomic diversity. The identification of strain-specific genes might explain how B. subtilis has become so broadly adapted. The goal of …

Feb 2, 2025 · Using Bacillus subtilis biofilms, we detected coherent alignment and chaining of wild-type cells towards the oxygen-rich capillary tip. In contrast, the ΔtasA genetic knock-out showed a loss of ...
