芽孢杆菌属细菌是一类广泛存在的革兰氏阳性菌,其中诸如炭疽芽孢杆菌、蜡样芽孢杆菌杆菌、短小芽孢杆菌、苏云金芽孢杆菌等为人类、动物、植物或昆虫的病原菌。噬菌体为细菌病毒,它和其编码的裂解酶在细菌性病害的防治中有着巨大的应用前景。同时,在工业发酵中,Bt噬菌体的污染可导致工业发酵的重大减产。 Bacillus bacteria are a wide range of Gram-positive bacteria, among which Bacillus anthracis, Bacillus cereus, Bacillus pumilus, Bacillus thuringiensis and the like are human, animal, plant or insect pathogenic bacteria. Bacteriophages are bacterial viruses, which, together with their encoded lytic enzymes, have great potential applications in the prevention and treatment of bacterial diseases. In the meantime, contamination of Bt phage in industrial fermentation can result in a significant reduction in industrial fermentation.
