Determined the effect of seven antibiotic substances upon Ceratostmella ulmi, the causative agent of Dutch elm disease.
Found that actinomycin and clavacin had a strong effect upon the fungus, while penicillin and streptothricin had no effect.
Determined that certain nutrients in the medium provide a neutralizing effect of the antibiotics to C. ulmi.
Compared different strains of fungi in the Aspergillus flavus-oryzae group.
Investigated whether these strains could produce antibiotic substances.
Demonstrated that not all strains behave the same and some produce useful antimicrobial compounds, while others do not.
Introduced streptomycin as a newly discovered antibiotic produced by Streptomyces griseus.
Demonstrated activity against both Gram-positive and Gram-negative bacteria.
Compared its effectiveness to other antibiotics, showing broader antibacterial activity.
Examined how antibiotic substances inhibit or kill different types of bacteria.
Demonstrated that antibiotics vary in their effectiveness depending on the organism.
Introduced the idea of an “antibiotic spectrum,” describing how certain antibiotics selectively act on certain bacteria.
Identified chaetomin, an antibiotic produced by the fungus Chaetomium cochliodes.
Demonstrated C. cochliodes can produce substances that inhibit microbial growth.
Contributed to early efforts to explore microorganisms as sources of antibiotics.
Identified a new antibiotic, micromonosporin, from Micromonospora bacteria.
Tested its antibacterial activity, mainly against Gram-positive bacteria.
Described how the antibiotic is produced, extracted, and its chemical properties.
Tested how penicillin affects the growth of Mycobacterium tuberculosis.
Found that high concentrations of penicillin could inhibit M. tuberculosis.
Showed effectiveness depends on bacterial amount (with smaller samples being more sensitive).
