A Penicillium species isolated during a 1960s study on the ecology of fungi infecting Pinus radiata timber, and subsequently held in an in-house collection in Rotorua, New Zealand, was found to differ morphologically and in growth rate from two closely related Penicillium species. Phylogenetic analysis of the rDNA internal transcribed spacer (ITS), β-tubulin, calmodulin and RNA polymerase II second largest subunit regions (RPB2) confirmed this to be a new species closely related to Penicillium ochrochloron in the Rolfsiorum series of the Lanata-Divaricata section and Aspergilloides sub-genus. Micromorphologically, the new species is characterised by predominantly monoverticilliate and occasional divaricate or biverticilliate conidiophores and smooth-walled subglobose to slightly ovoid conidia with absence of conidiogenesis at 25 °C. This new species is described here as Penicillium rotoruae sp. nov. which has potential applications in biofuel and biorefining industry.

Penicilliumrotoruae,来自新西兰地下木材耐久性试验场的新物种

在 1960 年代对感染辐射松木材的真菌生态学研究中分离出的一种青霉属物种,随后在新西兰罗托鲁瓦的内部收藏中被发现,其形态和生长速度与两种密切相关的青霉属物种不同。对 rDNA 内部转录间隔区 (ITS)、β-微管蛋白、钙调蛋白和 RNA 聚合酶 II 第二大亚基区域 (RPB2) 的系统发育分析证实,这是一个与毛茛属部分 Rolfsiorum 系列中的青霉密切相关的新物种和曲霉亚属。在微形态学上,新物种的特点是主要是单轮枝孢子体,偶尔有分生孢子或双轮枝孢子梗,以及壁光滑的近球形至略卵球形的分生孢子,在 25 °C 下没有分生孢子发生。这个新物种在这里被描述为旋转青霉 sp。十一月 在生物燃料和生物精炼行业具有潜在应用。
