The anti-inflammatory activities of marine actinomycetes were surveyed. In total, 363 strains were isolated from marine sediments, seaweed tissue, and seaweed rhizosphere. Of these, strains 16 and 291-11 showed the most potent anti-inflammatory activity in phorbol-ester-induced mouse ear edema and erythema assays. Strains 16 and 291-11 were isolated from the rhizosphere of the brown seaweeds Sargassum thunbergli and Undaria pinnatifida, respectively, and were identified as Streptomyces macrosporeus and St. praecox, respectively, using 165 rDNA sequence analysis.

Arthrinium (Ascomycota, Apiosporaceae) is a major marine fungal genus. Three Arthrinium species were reported previously, but not fully described. We isolated the two species A. arundinis and A. saccharicola from Sargassum sp. brown algae in Jeju Island, Korea. These species have not been previously reported in Korea. We described these species in detail and performed a phylogenetic analysis based on the nucleotide sequences of the EF1-${\alpha}$ and ${\beta}$-tubulin genes.

White spot syndrome virus (WSSV) is a strong causative agent for high mortality in cultured and wild shrimps. From this study, the WSSV prevalence in marine organisms around shrimp farm as well as live feed-mediated transmission of WSSV to farmed shrimps were investigated. Based on nested-PCR method, WSSV was detected in wide array of marine organisms including Perinereis aibuhitensis (81.3% of prevalence rate, 13/16), Enedrias fangi (100%, 16/16), Ruditapes philippinarum (20%, 2/10), crab larvae (100%, 10/10), copepoda (30%, 3/10), Periophthalmus modestus (50%, 5/10), Pachygrapsus crassipes (10%, 1/10), Helice tridens (20%, 2/10) and Neomysis sp. (70%, 7/10). On the other hand, WSSV was not detected in Bullacta exarata, Uca arcuata, and Reishia clavigera. The percent prevalence of WSSV in wild shrimps, Fenneropenaeus chinensis was only 6%, but markedly increased up to 56% after a feeding trial using polychaete worms for one month, indicating that the live feed is one of significant carriers of WSSV to shrimps under practical farming conditions.

The delesseriacean parasitic red algal Asterocolax species was collected from Jindo in the southern coast of Korea. This parasitic species found on Pseudopolyneura japonica. And it is distinct from other species of Asterocolax with more or less denticulate branches when matured. This Korean entity is identified as Asterocolax denticulatus (Tokida) Feldmann & Feldmann (Delesseriaceae, Rhodophyta) based on these features. This is the first record of A. denticulatus in Korea.

It is preyed that marine algae, Chlorella pyrenoidosa can synthesize about 3.52% of eicosapentaenoic (EPA) of dry cell weight at the light intensity of 10 W/$\m^2$ which is optimal light intensity of producing EPA at $25^{\circ}C$. An equation to predict the amounts of EPA in the culture broth is derived as an exponential form with 0.91 of the correlation factor. The behavior of cell growth follows a photo-inhibition model by showing 12 W/$\m^2$ of saturation light intensity.
