Explanation:

1. Statement about Robert Koch: Robert Koch indeed was aware that healthy animals could carry pathogens and modified his postulates accordingly, so this is a correct statement.
2. Statement about Winogradsky: Winogradsky discovered lithotrophs that can obtain energy from inorganic sources and use carbon - dioxide for growth, so this is a correct statement.
3. Statement about live, non - attenuated vaccines: Live, non - attenuated vaccines are not the safest choice for immunization as they can potentially cause the disease they are meant to prevent, so this statement is false.
4. Statement about Archaea: Domain Archaea contains prokaryote cell types, which is a correct statement.
5. Statement about unculturable microbes: Unculturable microbes have been revealed through metagenomics studies, which is a correct statement.

Answer:

The false statement is: Live, non - attenuated vaccines are the safest choice for immunization of individuals.
