Fluorescence fingerprints of Eisenia fetida and Eisenia andrei¶

We describe a fluorescent method that allows to differentiate the worms Eisenia fetida and Eisenia andrei. In fact, the coelomic fluid of E. andrei displays specific fluorescence absent in that of E. fetida. The two species do not metabolize the same types of molecules and thus can be differentiated at the molecular level. Each species has specific fluorescence fingerprints.
