Zygosporium geminatum, isolated as a contaminant in a culture of the mycelial phase of Paracoccidioides brasiliensis, was lethal to the latter organism. Its lytic action was due to exocellular alpha-1,3- and beta-1,3-glucanases which degraded the P. brasiliensis cell wall. The alpha-1,3-glucanase was more active at 30 degrees C and the beta-1,3-glucanase at 23 degrees C, each having pH 6.0 as its optimum.
双孢接合菌（Zygosporium geminatum）作为巴西副球孢子菌（Paracoccidioides brasiliensis）菌丝体阶段培养物中的污染物被分离出来，对后者具有致死性。其溶解作用归因于细胞外α-1,3-和β-1,3-葡聚糖酶，这些酶可降解巴西副球孢子菌的细胞壁。α-1,3-葡聚糖酶在30℃时活性更高，β-1,3-葡聚糖酶在23℃时活性更高，两者的最适pH均为6.0。
