Abstract
A spontaneously occurring variation of Aerobacter levanicum, affecting the appearance of colonies on sucrose agar (opaque to translucent colony form), has been observed and studied. This appears to be a mutation that is accompanied by a significant increase in levansucrase (EC 2.4.1.10) activity, in levan production, and by a change in some of the properties of levansucrase.
摘要
已观察并研究了产气肠杆菌的一种自发变异，该变异影响其在蔗糖琼脂上菌落的外观（从不透明菌落形态变为半透明菌落形态）。这似乎是一种突变，伴随着果聚糖蔗糖酶（EC 2.4.1.10）活性显著增加、果聚糖产量增加以及果聚糖蔗糖酶某些特性的改变。
