南极菲尔德斯半岛生物体的微生物含量分析

ANALYSIS OF MICROBIAL CONTENTS OF LIVING MATERIALS IN FILDES PENINSULA,ANTARCTICA

于１９９３／１９９４年以平板培养法用５种基本培养基对南极菲尔德斯半岛地区的生物体作了微生物含量分析。所研究的海藻、苔藓、地衣、沙蚕、小红蛤、帽贝、鱼、企鹅和鲸等的体表和体内样本计３３个。分析和比较了各类生物体内外所含的陆源性细菌、海洋性细菌、肠细菌、真菌及耐酸细菌等的含量，在一定程度上，培养温度的提高可促进样本中原有的微生物迅速大量繁殖，表明低温仍是制约南极微生物的重要因子。

The analysis of microbial contents of living materials in Fildes Peninsula,Antarctica was made by using the plating method with five basic culture media during the austral summers from 1993 to 1994. The 33 samples of the surface and inner materials of their bodies collected were marine algae,mosses,lichen,sea worm,little red clam,cap shaped shell,fish,penguin and whale. It was analyzed and compared to the contents of terrigenous. Marine,intestinal,acid fast bacteria and fungi of each category of organisms. The appropriate rise of incubation temperature promoted the multiplication of the microbes rapid and a large number at some degree. It suggests that the low temperature is still an important factor for restricting the microorganisms in Antarctica.
