Abstract

The colonial morphology and growth of Penicillium claviforme and P. clavigerum in manganese-deficient, defined medium, were examined with and without manganese supplementation. In unsupplemented medium rendered free of manganese through treatment with a chelating resin, P. claviforme grew but did not produce coremia. Similar results were obtained for P. clavigerum on media devoid of added manganese. However, when these media were supplemented with optimal concentrations of manganese both fungi produced coremia. The presence of manganese in various colony sections oed in the conidia.

摘要

在有无添加锰的情况下，研究了棒形青霉和棒状青霉在缺锰的特定培养基中的菌落形态和生长情况。在用螯合树脂处理以去除锰的未添加培养基中，棒形青霉生长但不产生束状分生孢子梗。在未添加锰的培养基上，棒状青霉也得到了类似的结果。然而，当这些培养基添加最佳浓度的锰时，两种真菌都产生了束状分生孢子梗。在分生孢子中检测到不同菌落部分存在锰。
