유기산 처리법을 이용하여 15℃ 저장 동안 생굴의 V. vulnificus strain 29307의 세균수 변화에 대한 영향을 조사하였다. 각각 3분 동안 0.5% 초산, 0.5% 유산, 또는 0.5% 구연산으로 침지한 생굴은 저장 4일 후부터 V. vulnificus가 검출되지 않았다. 2% 초산 함유한 3% 알지닉산 처리구는 저장 2일 후부터 V. vulnificus가 검출되지 않았으며, 수돗물로 처리한 대조구는 저장 4일동안 V. vulnificus가 분리되었다. 본 연구의 결과를 토대로 알지닉산과 초산의 조합은 각 유기산 처리구보다 V. vulnificus에 대한 항균력을 증진하였다.

The number of Vivrio vulnificus strain 29307 was assessed for oysters treated with acetic, lactic, citric, and alginic acids during storage at 15℃. When oysters were dipped with 0.5% acetic, 0.5% lactic, or 0.5% citric acids for 3 min, V. vulnificus was not detected after 4 days of storage. V. vulnificus in the treatment of 3% alginic acid (AL) containing 2% acetic acid (AA) was not detected after 2 days of storage, while it was isolated in the controls for 4 days of storage. Based on these results, the combination of AL and AA was more effective for preventing the growth of V. vulnificus in oysters than the treatments of the acid alone.
