노무라 입깃 해파리(Nemopilema nomurai)로부터 항균활성물질의 분리 및 정제 = Isolation and Purification of an Antimicrobial Material from the Jellyfish Nemopilema nomurai

다국어 초록 (Multilingual Abstract)

An antimicrobial material was purified from the acidified whole body extract of the jellyfish Nemopilema nomurai by using C18 reversed phase and cation-exchange high performance liquid chromatography (HPLC). Whole body extract and the purified compound (JAP-1) showed potent antimicrobial activities against a wide range of microorganisms including Escherichia coli D31, Bacillus subtilis, Streptococcus iniae and Candida albicans, without significant hemolytic activity. Treatment of JAP-1 with trypsin completely abolished all antibacterial activity against Bacillus subtilis, suggesting that JAP-1 is likely to be a proteinaceous antibiotic. The molecular weight of JAP-1 was determined to be 680.10 Da by MALDI-TOF mass spectroscopy.
