Protective antimicrobial coverings containing amber and propolis
Compositions in the form of pencils and varnishes containing amber and propolis may be used for creation of protective films to prevent the growth and development of the fungusesAspergillusniger and Penicillumculmorum,bacterias Bacillus subtilis, Bacillus turengensis, and other commonly encountered on many surfaces in residential and industrial areas, in bio-filters, in hermetic premises, including space stations. Pencils are compact, hygienic and easy to use, but the protective properties of varnishes are more pronounced.
