During the mid-20th century, which scientific practice was the primary method used to identify new drugs and led to the discovery of erythromycin?

Answer

Soil sampling

During the period known as the Golden Age of Antibiotics, researchers extensively practiced soil sampling to find new antibiotic-producing bacteria. Scientists believed that diverse environments, particularly tropical soils, contained unique bacterial strains capable of resisting other microorganisms. This strategy involved isolating soil samples and analyzing them in laboratory settings, which is how the bacteria responsible for erythromycin were identified.
