Summary
A total of 40 actinomycete strains, isolated from Antarctica, were tested
for antagonistic activity against 7 Gram-positive and Gram negative bacteria
and yeasts, 16 phytopathogenic fungi and bacteria. During the initial screening
60 % of the strains showed inhibition potential against test-microorganisms.
Ten of them had a broader spectrum of antibacterial activity and could be used
in the development of new substances for pharmaceutical or agricultural
purposes.
