Bacillus globigii, also known as Bacillus subtilis var. niger or B. atrophaeus, is a Gram-positive, rod-shaped bacterium commonly found in soil, water, and air. It is a non-pathogenic, spore-forming organism that belongs to the genus Bacillus and the family Bacillaceae.
The species name "globigii" refers to the round spores produced by this bacterium. The spores of Bacillus globigii are highly resistant to heat, desiccation, and various chemical agents, making it a popular choice for studying microbial resistance and control. They can remain viable in harsh conditions for extended periods and are often used as a biological indicator for sterilization processes.
Bacillus globigii is widely used in laboratories and industry for various purposes. It is commonly employed as a model organism to study the physiological processes, genetics, and biochemistry of bacteria due to its rapid growth, ease of cultivation, and genotypic stability. Additionally, Bacillus globigii is utilized in the production of industrial enzymes, antibiotics, and other bioactive compounds.
While Bacillus globigii is generally considered safe and non-pathogenic, some strains possess genes that enable them to survive and thrive in certain host environments, including human hosts. These rare strains have been implicated in opportunistic infections, particularly in individuals with compromised immune systems. Overall, the study of Bacillus globigii provides valuable insights into microbial ecology, the dynamics of bacterial spore formation, and the development of effective decontamination and sterilization methods.
