Figure 1: The role of bacteria in the transformation of caffeine in H. hampei.
From: Gut microbiota mediate caffeine detoxification in the primary insect pest of coffee
(a) Experimental design and analysis of caffeine concentrations in the frass of control and antibiotic-treated H. hampei specimens. Antibiotic-mediated depletion of the H. hampei microbiome eliminates the transformation of caffeine and increases caffeine excretion. (b) FTIR profiles for pure caffeine (black), frass of control (non-antibiotic-treated insects—red) and frass of antibiotic-treated insects (green). Depicted profiles represent the average of all measurements (n=6).
