Isolation and characterization of secondary metabolites from Arctic, Marine Invertebrates
The search for bioactive compounds, or genes in macro- and microorganisms from the sea, is termed marine bioprospecting. Marine bioprospecting aims to increase the utilization and value of marine biomasses and organisms with the purpose of developing commercial products. Because of the special condi...
