The production of extracellular deoxyribonuclease and ribonuclease by 23 marine and 3 dairy strains of Pseudomonas putrefaciens, 15 strains of fish-pathogenic fluorescent pseudomonads, 38 strains of fluorescent pseudomonads isolated from haddock, and 34 related organisms was determined by an agar plate method. All strains of P. putrefaciens produced both deoxyribonuclease and ribonuclease. Of the other 87 organisms examined, 26.5% produced ribonuclease and 14.5% produced deoxyribonuclease. All organisms which produced deoxyribonuclease also produced ribonuclease. Deoxyribonuclease production by P. putrefaciens is suggested as a useful criterion of identity for members of this intense fish spoilage species.
采用琼脂平板法测定了23株海洋腐败假单胞菌、3株乳源腐败假单胞菌、15株鱼致病性荧光假单胞菌、38株从黑线鳕中分离出的荧光假单胞菌以及34株相关微生物产生细胞外脱氧核糖核酸酶和核糖核酸酶的情况。所有腐败假单胞菌菌株均能产生脱氧核糖核酸酶和核糖核酸酶。在检测的其他87种微生物中，26.5%能产生核糖核酸酶，14.5%能产生脱氧核糖核酸酶。所有产生脱氧核糖核酸酶的微生物也都能产生核糖核酸酶。建议将腐败假单胞菌产生脱氧核糖核酸酶作为该严重致鱼腐败菌种成员鉴定的一个有用标准。
