“特效药”是指微生物化学制品对于致病细菌、真菌和肿瘤的选择性作用。它的发现开创了“抗生素时代”。四十多年来我们已成了抗生素的卓越疗效的受益者。微生物次级代谢物的应用成功率竟如此之高,在抗细菌、抗真菌和抗肿瘤的化学治疗上占有优势。但不幸地,认为微生物次级代谢物的潜力有限的观点已妨碍了发酵工业的进一步发展。许多工业微生物学家子感到抗生素的活性几乎 “Potency” refers to the selective action of microbial chemicals on pathogenic bacteria, fungi and tumors. Its discovery opened the era of antibiotics. For more than 40 years we have become the beneficiaries of the remarkable efficacy of antibiotics. The success rate of microbial secondary metabolites is so high, in the anti-bacterial, anti-fungal and anti-tumor chemotherapy advantage. Unfortunately, however, the view that the potential of microbial secondary metabolites is limited has hindered the further development of the fermentation industry. Many industrial microbiologists feel almost the antibiotic activity
