Note(s): Harbor Branch Oceanographic Institution (HBOI) has a worldwide collection of over25,000 marine macro-invertebrates and algae representing diverse geographical,latitudinal, and depth (0-3000 ft) ranges. Samples are tested for biological activity in apanel of whole cell and enzyme/receptor assays, including antibacterial, antifungal,cytotoxicity, antitumor, and immunomodulatory assays. Of the taxa sampled, Poriferahave the greatest incidence of activity within these screens and especially within theantimicrobial assays. Cnidaria, Chordata (Ascidiacea), Phaeophyta, and Chlorophytaalso show strong antimicrobial activity. A comparison of bioactivity and depth ofcollection indicates that benthic organisms are active throughout the depth range of thisstudy. Antifungal activity is greatest for high latitude samples then decreases at thelower latitudes, whereas antibacterial activity decreases markedly above 30°N latitude.Strong site-specific trends also exist regardless of latitude or temperature. For example,samples from both the Bahamas and Seychelles show very strong activities for allassays whereas samples from various other tropical, warm water sites such as theVirgin Islands, Senegal, Colombia, Venezuela, and Sierra Leone are inactive in theenzyme assays. Data are used to target potential taxonomic and geographic sources ofnatural products for drug discovery to treat human diseases or as biomedical researchtools.
