Acorn worm Balanoglossus biminiensis

Dure and Cormier (1961) demonstrated a luciferin-luciferase reaction for the first time in the extracts of the acorn worm Balanoglossus biminiensis, and also discovered that the luminescence reaction is stimulated by H2O2, of which the details are described below. Recently, Kanakubo and Isobe (2005) reported the chemical structure of a probable luciferin of another acorn worm Ptychodera flava.
