To know the value of the solubilization method using tissue solubilizer Soluene-350 in diagnosis of drowning, mice (ICR) were drowned artificially with the fresh water of Chungju district. Chlorophyta (or green algae), such as Oocystis and Eudorina, as well as diatoms, such as Diatoma, Synedra and Cyclotella were detected with other algae including Microcystis, Oscillatoria, Trachlomonas, Altenaria and Cephalodella in the water of Daeje-ji(Dae-je pond). This method is useful in detection of green algae and other kinds of algae for diagnosis of drowning in submerged bodies among legal autopsy cases.

Soil cyanobacteria isolated from the rice paddy fields of 10 different locations across Korea were evaluated by agar plate diffusion test for antifungal activity. Aqueous, petroleum ether, and methanol extracts from one hundred and forty two cyanobacterial strains belonging to the 14 genera were examined for antifungal properties against seven phytopathogenic fungi causing diseases in hot pepper (Capsicum annuum L). Of total cyanobacteria, nine cyanobacteria (6.34%) exhibited antifungal effects. The nine cyanobacteria selected with positive antifungal activities were two species of Oscillatoria, two of Anabaena, three of Nostoc, one of Nodularia, and one of Calothrix. Alternaria alternata and Botrytis cinerea were inhibited by nine and eight species of cyanobacteria, respectively. Rhizopus stolonifer was suppressed by only methanol extract of Nostoc commune FK-103. In particular, Nostoc commune FK-103 and Oscillatoria tenuis FK-109 showed strong antifungal activities against Phytophthora capsici. Their antifungal activity at the late exponential growth phase is related to the growth temperature and not associated with the growth parameters such as cell biomass and chlorophyll-alpha concentration. The high inhibition levels of antibiotics were 22.5 and 31.8 mm for N. commune FK-103 and O. tenuis FK-109, respectively. The optimal temperature for antibiotic productivity was 35degrees C.
