Hazard alerts

The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement. These hazard alerts do not take account of usage patterns or exposure, thus do not represent risk.

Commercial production

Commercial production of Bacillus species typically involves large-scale aerobic fermentation. The process begins with selecting a robust strain, often genetically optimised for yield and stability. These bacteria are cultivated in bioreactors under tightly controlled conditions, temperature (usually 30–37 degrees C), pH (neutral to slightly alkaline), and oxygen levels are carefully regulated to maximise growth and productivity. Nutrient-rich media, often containing glucose or other carbon sources, support rapid biomass accumulation. After fermentation, the culture is harvested, and the desired products, such as enzymes or spores, are extracted and purified.
