The natural, non-genetically modified microorganisms used are free

to use, listed and classified for a long time by science and state services. Directive 2000/54/CE1 and the EFB (European Federation

of Biotechnologies - CR 12894:1997) have classified known microorganisms into 5 categories. Microorganisms used and authorized in bioremediation

and environmental protection are class 1.

This class contains microorganisms, which have never been described

as a causative agent of diseases in humans and which do not constitute a threat to the environment (EFB). They are authorized,

without reference to the competent authority for the protection

workers (directive article 2).

These microorganisms belong to the same category as those used

in industrial food.
