Clostridia Isolated from the Soil in the East Coast of Lutzow-Holm Bay, East Antarctica
From the soil (permafrost, moraine, penguins' rookery, lake, coast, etc.) collected in the area around Syowa Station, the Antarctica during 1972-1973, 150 strains of Clostridium were isolated and identified according to the VPI manual. 1) C. perfringens (28%), C. sordellii (22%), C. bifermentan...
