Abstract

The growth and the metabolic activity of Shewanella putrfaciens, Brochothrix thermosphacta, and Pseudomonas sp., when cultured individually or in all possible combinations in gel cassettes system supplemented with 0.1% glucose at 5 degrees C, were investigated. The overall outcome was that the coexistence of the above-mentioned microorganisms affected not only each growth rate but also their type of metabolic end products compared to the control cultures. These effects were varied and depended on the selection of the combination of the tested bacteria. For example, the growth of Pseudomonas sp. strains cocultured with either B. thermosphacta or S. putrefaciens strains resulted in different effects: a promoting one for the first and an inhibitory one for the second. Moreover, the production of formic acid and two unidentified organic acids (peaks a and b) was characteristic in all cases in which S. putrefaciens was cultured.

摘要

研究了在补充有0.1%葡萄糖的凝胶盒系统中于5℃单独培养或进行所有可能组合培养时,腐败希瓦氏菌、嗜热栖热菌和假单胞菌属的生长及代谢活性。总体结果是,与对照培养物相比,上述微生物的共存不仅影响每种微生物的生长速率,还影响其代谢终产物的类型。这些影响各不相同,且取决于所测试细菌组合的选择。例如,与嗜热栖热菌或腐败希瓦氏菌菌株共培养的假单胞菌属菌株的生长产生了不同的影响:对前者有促进作用,对后者有抑制作用。此外,在所有培养腐败希瓦氏菌的情况下,甲酸和两种未鉴定的有机酸(峰a和峰b)的产生是其特征。
