L.

Dyes employed, such as trypan blue, pose risks to health and environment. Alternative dyes such as pen ink and aniline have variable coloring efficiency. In this work, Brachiaria decumbens roots, discolored with caustic soda (NaOH), were stained with açai, annatto, saffron, trypan blue and pen inks. There were significant differences among dyes regarding stained mycorrhizal structures and pictures quality. Acai was considered the best alternative dye, with similar results to trypan blue.  anatural dyes  aAçafrão  aAçaí  aMicrobiologia do Solo  aUrucum  aCorante natural  aMicorriza arbuscular  aSoil microbiology1 aSANTANA, M.
