Abstract
Secretion of beta-1,3-glucanases by the arctic bacterial isolates 4221 and 4236, related to the genera Flavobacterium and Pedobacter, was discovered. Escherichia coli and Lactococcus lactis expression of beta-1,3-glucanases Glc4221-1 and Glc4236-1 from the respective isolates was achieved. The enzymes hydrolyzed fungal cell walls and retained activity at low temperatures.
摘要
发现了与黄杆菌属和 Pedobacter 属相关的北极细菌分离株 4221 和 4236 分泌 β-1,3-葡聚糖酶。实现了大肠杆菌和乳酸乳球菌对来自各自分离株的 β-1,3-葡聚糖酶 Glc4221-1 和 Glc4236-1 的表达。这些酶可水解真菌细胞壁并在低温下保持活性。
