SUMMARY

Hazard alerts

The following Pesticide Hazard Tricolour (PHT) 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. The alerts for Highly Hazardous Pesticides (HHPs) are based on applying the FAO/WHO (Type 1) and the PAN (Type II) criteria to PPDB data. Further details on the HHP indicators are given in the tables below. Neither the PHT nor the HHP hazard alerts take account of usage patterns or exposure, thus they do not represent risk.

PHT: Environmental fate	PHT: Ecotoxicity	PHT: Human health	Highly Hazardous Pesticide
		Human health High alert: Reproduction/development effects Warning: Significant data are missing

Formulation and application details

Commercial production

The primary method for producing surfactin C is through microbial fermentation. Bacillus subtilis is cultivated in a nutrient-rich medium, often using agro-industrial waste products like potato peel waste and frying oil waste to reduce costs. The production process is optimised to maximize yield. This includes adjusting factors such as pH, temperature, and nutrient concentrations. Genetic engineering and selective breeding are employed to create strains of B. subtilis that produce higher quantities of surfactin C. After fermentation, surfactin C is extracted from the culture medium. This typically involves techniques like solvent extraction, precipitation, and chromatography to purify the substance.

Impact on climate of production and use

As microbial-based products tend to use fermentation-based production processes rather than chemical synthesis, they typically have a lower fossil fuel input in formulation and active ingredient creation, and also have reduced downstream emissions due to biodegradability and minimal soil disruption, their life-cycle GHG emissions are expected to be low. Whilst hard and precise data is not available, broad estimates suggest that typically emissions are likely to be below 5 kg CO₂e/kg.
