Most endogeic earthworms have weak enzymatic complement and they usually establish mutualistic relationships with soil microflora to digest some organic compounds. Therefore, the intestinal wall tissues were cultured in vitro to assess the origin of the glycolytic enzymes found in the gut and enzymatic activities were measured in both cultured tissues and culture media. H. elisae had a wide but not very strong enzyme complement, since all substrates were degraded but most of them at a low rate. This species cannot produce cellulase and mannamase, so for the digestion of these substrates it probably uses the digestive enzymatic capabilities of the ingested microflora.
