A novel species, Aspergillus brasiliensis sp. nov., is described within Aspergillus section Nigri. This species can be distinguished from other black aspergilli based on intergenic transcribed region, beta-tubulin and calmodulin gene sequences, by amplified fragment length polymorphism analysis and by extrolite profiles. A. brasiliensis isolates produced naphtho-gamma-pyrones, tensidol A and B and pyrophen in common with Aspergillus niger and Aspergillus tubingensis, but also several unique compounds, justifying their treatment as representing a separate species. None of the isolates were found to produce ochratoxin A, kotanins, funalenone or pyranonigrins. The novel species was most closely related to A. niger, and was isolated from soil from Brazil, Australia, USA and The Netherlands, and from grape berries from Portugal. The type strain of Aspergillus brasiliensis sp. nov. is CBS 101740(T) (=IMI 381727(T)=IBT 21946(T)).
在黑曲霉组中描述了一个新种,巴西曲霉(Aspergillus brasiliensis sp. nov.)。该物种可通过基因间转录区域、β-微管蛋白和钙调蛋白基因序列、扩增片段长度多态性分析以及次生代谢产物谱与其他黑曲霉区分开来。巴西曲霉分离株与黑曲霉和土曲霉共同产生萘并γ-吡喃酮、表面活性剂A和B以及焦酚,但也产生几种独特的化合物,这证明将它们视为一个单独的物种是合理的。未发现任何分离株产生赭曲霉毒素A、科他宁、富纳伦酮或吡喃黑菌素。该新物种与黑曲霉关系最为密切,从巴西、澳大利亚、美国和荷兰的土壤以及葡萄牙的葡萄浆果中分离得到。巴西曲霉新种的模式菌株为CBS 101740(T)(=IMI 381727(T)=IBT 21946(T))。
