Abstract
The ability of Yarrowia lipolytica to produce ammonia from urea was found variable on some media. The colour change of the indicator in Christensen's urea agar was not due to the urease activity of this species but was a non-specific alkalization reaction. Rapid urea broth was reliable giving no false positive results. It was found that Y. lipolytica is a urease negative yeast species.
摘要
解脂耶氏酵母在某些培养基上从尿素产生氨的能力存在差异。克里斯滕森尿素琼脂中指示剂的颜色变化并非由于该菌种的脲酶活性，而是一种非特异性碱化反应。快速尿素肉汤可靠，无假阳性结果。研究发现解脂耶氏酵母是一种脲酶阴性酵母菌种。
