Urea splitting bacteria are related to the formation of struvite or apatite. We investigated the urease activity of bacteria by two methods; the direct measurement of urease activity of viable bacteria and sonicated bacteria from amounts of ammonia by the indophenol method, and the measurement of urease activity by alkalization of infected urine. Proteus mirabilis and Pseudomonas aeruginosa had moderate activity of urease, and Morganella morganii and Staphylococcus epidermidis had the most powerful activity. P. mirabilis caused the strongest alkalization in infected urine.
尿素分解菌与鸟粪石或磷灰石的形成有关。我们通过两种方法研究了细菌的脲酶活性：一种是通过吲哚酚法，从氨的量直接测量活菌和经超声处理的细菌的脲酶活性；另一种是通过感染尿液的碱化来测量脲酶活性。奇异变形杆菌和铜绿假单胞菌具有中等脲酶活性，摩根摩根菌和表皮葡萄球菌具有最强的活性。奇异变形杆菌在感染尿液中引起的碱化作用最强。
