Researchers from Tomsk Polytechnic University (TPU) study the biosynthesis of three types of antibiotics from plants.
Although it will not be a drug for humans, but a drug for protection of plants – phenazine-1 carbonic acid, hydroxyphenazine and hydroxyphenazine-1-carbonic acid active against phytopathogenic bacteria. Currently these substances are obtained by chemical synthesis. It is not safe, requires precautionary measures. Researchers from Tomsk suggested that these substances may be obtained from non-pathogenic bacterial strains of pseudomonades, which is cheaper and, above all, is a safe and environmentally friendly technology.
Bacteria are placed into a special liquid nutritional medium, where they synthesize antibiotics. In a few days the desired substances are extracted from the nutritional medium.
It is important to note, that the antibiotics thus obtained have no adverse effects on plants, do not fit into their structure and are non-hazardous for humans.
