Glyphosate-Tolerant Microorganisms and the Sustainability of Coffee Farming: A New Perspective

The cultivation of Conilon coffee (Coffea canephora) is a cornerstone of the economy in Brazil. However, the intensive use of glyphosate poses significant challenges, including the presence of residues in coffee beans, which can hinder exports to markets with stricter regulations, such as the European Union. This opinion paper discusses the importance of bioprospecting for native glyphosate-tolerant bacteria with plant growth-promoting characteristics as a sustainable alternative to mitigate the negative impacts of this herbicide. We argue that the use of microbial consortia composed of native strains represents a promising strategy to reduce glyphosate residues, improve soil health, and promote the growth of coffee plants, thus contributing to a more resilient and environmentally balanced coffee production chain.
