In 2007, a study done by B.E. Barragan Huerta et al. tested positive with the idea that green bean coffee extractcould serve as a nutrient to enrich the growth of pesticide degrading bacteria, namely Pseudomonas aeruginosa and Flavimonas oryzihabitans (which were found in said coffee beans). The bacteria grew in glucose media with 50ppm DDT or endosulfan, which are major components of organochlorine pesticides.
