摘要：
Aspergillus niger is known for its efficient excretion machinery. However, problems have often arisen in obtaining high amounts of heterologous proteins in the culture medium. Here we present a quick method using sandwiched colonies to evaluate transgenic strains for secretion of heterologous proteins. Expressing the ABH1 hydrophobin of Agaricas bisporus in A. niger; we showed that low production levels of the heterologous protein are probably due to extracellular proteolytic degradation of the protein.
