Abstract
Description
도 2는 식염 펩톤수 (37 ℃) 중 pH 5에서의 2회 반복 (시험 1 및 2)으로의 2종의 피부 병원체인 슈도모나스 아에루지노사 ( Pseudomonas aeruginosa ) ATCC 9027 (1.4 x 106 cfu/ml) 및 스태필로코쿠스 아우레우스 (Staphylococcus aureus ) ATCC 6538 (4.3 x 106 cfu/ml)에 대한 0.65 % (w/w) 키토산 락테이트 용액의 항박테리아 활성을 나타낸다. 검출 한계: 여기서 1 cfu/ml는 검출되지 않음을 표시함 (<1 cfu/ml).
도 3은 어육 박테리아 표면 오염을 감소시키는 키토산 아세테이트 세정 용액의 처리 시간 (0-60-120분) 및 희석 (dil 10x-50x-100x)의 효과에 대한 시험관내 연구를 요약하고 있다. 희석 매체는 어육 박테리아 균주인 리스테리아 모노사이토제네스 ( Listeria monocytogenes), 슈도모나스 종군 및 슈와넬라 푸트레파시엔스 ( Shewanella putrefaciens )를 사용한 접종 전에 가열 (1 어육:9 물), 오토클레이빙 (121 ℃에서 15분) 및 여과에 의해 제조된 연어육 추출물이었다. 효과: 60분 후 2-log (dil 10x) 및 1-log (dil 50x) 하락.
도 4는 처리-후 얼음 저장 동안의 내장을 제거한 대구 (2회 반복 샘플) 전체의 피부 상에서의 손상 박테리아 (슈도모나스 및 H2S-생성 박테리아)의 증식에 대한 처리 유형 (대조, 키토산 세정 또는 코팅)의 효과에 대한 연구를 요약하고 있다. 결과: 키토산 코팅이 세정 처리에 비해 어육 손상 박테리아의 성장을 지체시키는 데에 있어서 더 효과적임. H2S-생성 박테리아는 슈도모나스에 비해 키토산 처리에 더 민감하다. 별표는 계수가 대조에 비해 유의성 있게 더 낮음을 표시한다 (p<0.05).
도 5는 16-일 얼음 저장 동안의 내장을 제거한 연어 (2회 반복 샘플) 전체의 피부 상에서의 미생물 증식에 대한 키토산 세정의 효과에 대한 연구를 요약하고 있다. 결과: H2S-생성 박테리아는 슈도모나스에 비해 키토산 처리에 더 민감하다. 세정 처리는 적어도 13일 동안 민감성 손상 박테리아를 지체시켰다. 별표는 계수가 대조에 비해 유의성 있게 더 낮음을 표시한다 (p<0.05).
