characteristics of uricase production by a Hyphomycetes isolated from the excrements of Cettia diphone cantans. iII. identification and microbiological properties of the strain

Examinations were made on the microbiological properties of Strain F1, a Hyphomycetes found in excrements of Cettia diphone cantans and showed some specific properties on the uricase formation. Colonies on the Czapek agar spread rather broadly, and were pale yellowish brown to avellaneous. Conidiophores were short, 10-20 μm, mostly arising from aerial hyphae. Annellophores were in a group of 3 to 4, or singly. Conidia were lemon-shaped or globose with flattened truncate base, verrucose-walled, measuring 7-9×5-7 μm. Details of conidia and other structures were observed under an electron microscope ; annellation on anellophore necks, marginal frill at the conidial base, etc. Physiologically, the strain decomposes arsenic compounds to release arsenic gas characterized by its garlic odor. From the examination of the morphological and physiological characteristics, together with various descriptions of the genus by several microbiologists, strain F1 is identified as Scopulariopsis brevicaulis (SACC.) BAINIER.
