Bacillus subtilis is a rod-shaped, catalase-positive bacterium that can form endospores and grow in soil and gut. It is a model organism for studying sporulation, chromosome replication and cell differentiation.
B. subtilis is a fast-growing, Gram-positive, aerobic bacterium with rod-shaped cells that are typically 2–6 µm long and just less than 1 µm in diameter. The optimal growth temperature is about 30–35 C, giving a doubling time of as little as 20 min.
15 Οκτ 2020 · Learn about Bacillus subtilis, a common and versatile bacterium that can survive extreme conditions and produce antimicrobial compounds. Find out how it is identified by Gram stain, used in probiotics and biotechnology, and degrades plastic.
Bacillus subtilis, strain 168 remains a case in point, and here we present an updated annotation, based on experimental evidence collected for this organism but also from other organisms, that we describe here with the aim of summarizing knowledge about this bacterium as a possible chassis for Synthetic Biology studies.
14 Αυγ 2023 · Gram stain is often the initial diagnostic test for the evaluation of infections. The use of Gram stain facilitates the rapid use of appropriate antibiotics. However, genetic sequences and molecular techniques are more specific than classic gram stain.
Learn how to perform a Gram stain and differentiate between Gram-positive and Gram-negative bacteria. See how Bacillus subtilis, a Gram-positive rod, can exhibit Gram stain variability.
The genome of Bacillus subtilis strain 168 was sequenced twenty years ago. Using a combination of inductive, deductive and abductive reasoning, we present a unique, manually curated annotation, essentially based on experimental data.
