Bacillus pumilus is a Gram-positive, aerobic, spore-forming bacillus commonly found in soil. [1]Bacillus pumilus spores—with the exception of mutant strain ATCC 7061—generally show high resistance to environmental stresses, including UV light exposure, desiccation, and the presence of oxidizers such as hydrogen peroxide.

[7] [139] [140] The correct definition of health benefit, backed with solid scientific evidence, is a strong element for the proper identification and assessment of the effect of a probiotic. This aspect is a challenge for scientific and industrial investigations because several difficulties arise, such as variability in the site for probiotic ...
ISAPP was created in 2000 by a group of professional scientists at a Fermented Foods and Health Meeting in New York. [3] This group recognized the lack of an organization that brought together the multidisciplinary scientists from fields such as microbiology, medicine, nutrition, food science, immunology, biochemistry and nutrition, who are conducting research on probiotics and prebiotics.
To increase the validity of a risk assessment, it is recommended that the assessment remain open for peer review and editing by food safety and science communities. A proper risk assessment is a constantly revolving process consisting of the following steps: (i) hazard identification, (ii) hazard characterization, (iii) exposure assessment, and ...
Colonies of B. cereus were originally isolated by Percy F. Frankland from a gelatine plate left exposed to the air in a cow shed in 1887. [11] In the 2010s, examination of warning letters issued by the US Food and Drug Administration issued to pharmaceutical manufacturing facilities addressing facility microbial contamination revealed that the most common contaminant was B. cereus.
Risk management tools help address uncertainty by identifying risks, generating metrics, setting parameters, prioritizing issues, developing responses, and tracking risks. [1] Without the use of these tools, techniques, documentation, and information systems, it can be challenging to effectively monitor these activities.
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.
The cortex lies beneath the spore coat and consists of peptidoglycan. The core wall lies beneath the cortex and surrounds the protoplast or core of the endospore. The core contains the spore chromosomal DNA which is encased in chromatin-like proteins known as SASPs (small acid-soluble spore proteins), that protect the spore DNA from UV ...
