Over the last decades, metabolites with biotechnological application produced by marine resources and notably macroalgae have seen increasing interest. Among these metabolites, many require the use of efficient extraction processes to reach a sufficiently high yield for industrial development. One of the more promising extraction processes currently used is the extraction assisted by enzymes, which can be coupled with other extraction techniques. However, most of the commercial enzymes used for the extraction of molecules of interest from marine material are enzymes obtained from terrestrial microorganisms and with limited substrate specificity. The efficiency of the extraction could then be increased by using more specific enzymes according to the targeted matrix. Marine fungi are particularly promising for the production of degradation enzymes and their interest recently increased, but they are still less studied than marine bacteria. A state of the art on the degradation enzymes from marine fungi is proposed, and more specifically on polysaccharide, protein and lipid degradation enzymes.
