Aspergillus carbonarius was recorded as a good producer of microbial cell wall lytic enzymes. The enzyme preparation effectively lysed both living and heat-treated cells of some bacteria and yeasts. Polymers of microbial cell wall constitution had been also hydrolysed. Production of the highest content of lytic enzymes was induced by killed cells of Escherichia coli. The crude preparation revealed its maximal bacteriolytic activity at pH 7.2 and 35 degrees C. Endo-1,3-beta--glucanase, mannanase and protease were the prevailing enzymes in this preparation.
炭黑曲霉被记录为微生物细胞壁裂解酶的良好生产者。该酶制剂能有效裂解一些细菌和酵母的活细胞及热处理细胞。微生物细胞壁组成的聚合物也被水解。大肠杆菌的死细胞诱导产生了最高含量的裂解酶。粗制剂在pH 7.2和35摄氏度时显示出最大的溶菌活性。内切-1,3-β-葡聚糖酶、甘露聚糖酶和蛋白酶是该制剂中的主要酶。
