Two amoebae were presented with six bacterial prey at a range of concentrations, and the growth parameters of the amoebae were deduced. All but one bacterium (Synechococcus) resulted in a positive growth response, but the gram-positive bacterium Staphylococcus aureus proved to be difficult to digest and the heavily pigmented bacterium Klebsiella ozaenae induced unusual amoebic behavior prior to ingestion.
向两个变形虫呈现了六种处于一系列浓度的细菌猎物,并推断出变形虫的生长参数。除了一种细菌(聚球藻属)之外,其他所有细菌都引发了积极的生长反应,但革兰氏阳性菌金黄色葡萄球菌被证明难以消化,而色素沉着严重的细菌鼻硬结克雷伯菌在被摄取之前引发了变形虫的异常行为。
