To evaluate associative growth of psychorotrophic P. aeruginosa and S. aureus with Y. enterocolitica 0:3, microorganisms were grown in trypticase soy broth in a diffusion apparatus (Ecologen) and incubated for 9 days at 4 degrees C. The effects of culture interactions were determined by growth curves, lag times, generation times, pH changes and acid production. The observed growth curves for Y. enterocolitica 0:3, P. aeruginosa and S. aureus, shows the stimulating effects of Y. enterocolitica 0:3 on growth of psychotrophic microorganisms in associative culture at 4 degrees C, although it was later inhibited by these organisms as they reached the stationary phase, thus proving itself to be a poor competitor with common spoilage microorganism.
为评估嗜冷性铜绿假单胞菌和金黄色葡萄球菌与小肠结肠炎耶尔森菌0:3的联合生长情况，将微生物接种于胰蛋白胨大豆肉汤中，置于扩散装置（Ecologen）中，于4℃培养9天。通过生长曲线、延滞期、代时、pH变化和产酸情况来确定培养相互作用的影响。观察到的小肠结肠炎耶尔森菌0:3、铜绿假单胞菌和金黄色葡萄球菌的生长曲线表明，在4℃的联合培养中，小肠结肠炎耶尔森菌0:3对嗜冷微生物的生长有刺激作用，尽管随着这些微生物进入稳定期，它后来受到抑制，从而证明其与常见腐败微生物相比竞争力较弱。
