About the book: 1968 / Did you know that the “union” of plants and microbes is much closer than previously thought? Microbial proteins become part of the body of plants, which, by the way, allow microbes to feed on the juices of their roots? Or that the study of the “war” of lower fungi with bacteria led to the discovery of antibiotics? But this is not enough. By voluntarily causing usually peaceful microorganisms to fight each other, man has learned to “manage” their relationships. The research goes further, and... ordinary brewer's yeast begins to attack cancer cells. The study of the structure of viruses and bacteriophages has greatly changed our knowledge of living nature. The world of microbes appears before man in all the diversity of the activities of its inhabitants, and the restructuring of this world begins at the request of man. About how this happened, what paths scientists followed and how in recent years it has been possible to remove the veil of mystery from many aspects of the life of the inhabitants of the “microcosm”, This book fascinatingly tells about their role in the existence of higher organisms and the Earth itself..
