This thesis describes the study of the secondary metabolites produced by two selected sponge-associated fungi with anti-tumor and anti-inflammatory activities.

Studies on the steroid components isolated from marine fungus No.2492 from the South China Sea;

Fermentation of fucoidanase production by marine fungus Dedryphiella Arenaria and enzyme properties;

Antibacterial metabolites from the fermentation broth of marine fungus 095407;

Preliminary studies on xylanase production of marine fungi Asteromyces sp. TM76;

Optimal cultivation conditions of marine fungi KLEB-07;

Study on the isolation of marine fungi , screening of their antitumor activity and fermentation conditions;

Isolation of algicolous fungi and screening of their antitumor activity;

Although almost one-third of all known higher marine fungi are associated with algae, algicolous fungi are relatively little investigated.

In this study we reported the isolation of compound P4 from algicolous fungi B5 and the structure identification by NMR and MS spectra.

Preliminary Study on the Bioactive Compounds from Metabolites of Two Marine-Derived Fungi;

Inhibition of extracts from four isolates of marine-derived fungi on plant pathogens

The nematicidal,brine shrimp lethality and acetylcholinesterase inhibitory activity of secondary metabolites from 188 marine-derived fungi were tested.
