| Abstract: | We studied the effect of sea water concentration in a culture medium on fungal growth and the production of antimicrobial metabolites. Most of the marine fungal isolates were identified as members of the same genera as terrestrial isolates, such asAspergillus andTrichoderma. Many of the marine fungi isolated grew more abundantly as the sea water concentration increased. The production of antimicrobial materials was improved as the sea water concentration increased. Even though the marine fungi were considered to be similar to fungi from terrestrial environments, from a mycological perspective, the two types have different physiological characteristics. The fungi from marine samples are useful microbial resources in the search for new bioactive compounds. |
