The aim of this study, therefore, is to design the fermented foods that are adaptable to low temperature, using psychrophilic bacteria isolated from Antarctica as starters, and to improve the physical properties of foods by using psychrophilic enzymes produced by psychrophilic bacteria. Bald rockcods, starfishes, sea urchins, and moss isolated from the surrounding area of Syowa Station mainly sampled as sources of psychrophilic bacteria were followed by enrichment culture. In Japan, the media inoculated with the enrichment samples were incubated at 4 oC for more than one week, we could confirm bacterial growth in some samples.

因此，本研究的目的是以从南极洲分离的嗜冷菌为发酵剂，设计出适应低温的发酵食品，并利用嗜冷菌产生的嗜冷酶来改善食品的物理特性。主要从昭和站周边地区分离出的秃鳕鱼、海星、海胆、苔藓等作为嗜冷菌的来源，进行了富集培养。在日本，接种富集样品的培养基在4℃下培养1周以上，可以确认部分样品中的细菌生长。
