Single-strain cultures of Pseudomonas fragi, P. fluorescens, P. putrefaciens, and strains of two marine species, Pseudomonas type I and Pseudomonas type II, were found to be capable of reducing added acetaldehyde, proprionaldehyde, and butyraldehyde to the corresponding alcohols at 21 C. All species studied reduced propionaldehyde at 6 C. P. fragi, Pseudomonas type I, and Pseudomonas type II reduced butanone at 6 and 21 C. P. fragi and Pseudomonas type II reduced acetone at 21 C. Dehydrogenase activity was found in some cultures in which growth was not evident. Under aerobic conditions, a strain of P. fragi reduced added propionaldehyde to n-propanol quantitatively within 36 hr at 21 C.
研究发现，嗜冷假单胞菌、荧光假单胞菌、腐败假单胞菌以及两种海洋假单胞菌菌株（假单胞菌I型和假单胞菌II型）的单菌株培养物，在21℃时能够将添加的乙醛、丙醛和丁醛还原为相应的醇类。所有研究的菌种在6℃时都能还原丙醛。嗜冷假单胞菌、假单胞菌I型和假单胞菌II型在6℃和21℃时能还原丁酮。嗜冷假单胞菌和假单胞菌II型在21℃时能还原丙酮。在一些未观察到明显生长的培养物中发现了脱氢酶活性。在有氧条件下，一株嗜冷假单胞菌在21℃时，能在36小时内将添加的丙醛定量还原为正丙醇。
