Abstract

Sponges live in a symbiotic relationship with microorganisms, especially bacteria. Here we show, using the demosponge Suberites domuncula as a model, that the sponge expresses the enzyme tyrosinase which synthesizes diphenols from monophenolic compounds. It is assumed that these products serve as carbon source for symbiotic bacteria to grow.

摘要

海绵与微生物，尤其是细菌，存在共生关系。在此，我们以海洋海绵纲的多孔海绵属为模型表明，海绵表达酪氨酸酶，该酶可从单酚类化合物合成二酚类。据推测，这些产物可作为共生细菌生长的碳源。
