Description of key information

Additional information

Yeast Saccharomyces cerevisiae (SC) is ubiquitous in nature and naturally occurring in all environmental compartments and animals. The presence of living yeast (SC) in environmental compartments implies the presence of dead yeast (SC) which composition can be compared to yeast SC's extract. No toxicity of SC and SC’s extract is expected in all terrestrial compartments.

Moreover, the macrocomposition of yeast extract, consisting of proteins, carbohydrates and salt, corresponds to elements composing all organisms. No toxicity of these elements is expected on environmental compartments.

Soil organisms are continuously and naturally exposed to SC and severe effects on non-target soil populations and communities are considered improbable.

No toxicity of S. cerevisiae, extract, is expected on terrestrial compartments and therefore, testing is not considered scientifically necessary.
