摘要：

Four colony variants (two stable and two unstable phenotypes) were observed in Bacillus subtilis alpha-10, an alpha-amylase-hyperproducing strain. The stable variants lost the ability to produce alpha-amylase, while the unstable ones reveried to the typical morphology after restreaking. Unstable expanding sectors appeared in typical colonies, and their appearance was influenced by the culture origin and age.
