Waste management of dark coniferous trees debarking for producing antibacterial preparations [Текст] / Ирина Владимировна Кротова, Галина Сергеевна Гуленкова, Наталья Алексеевна Осмоловская, Ростислав Юрьевич Смирнов // IOP: Conference Series: Earth and Environmental Series. — 2019. — Т. 315.Аннотация:
The article presents the results of studying the antibacterial activity of fir tree an
Siberian spruce bark water extracts. As test objects, pathogenic (3-4 hazard class) and
saprotrophic bacteria were used. It has been shown that the studied aqueous extracts of darkd
coniferous bark do not exhibit biocide activity against the conditionally pathogenic bacterium-
Escherichia coli. However, all the other studied bacteria are sensitive to the extracts analyze
both on day 3 and day 13. At the same time, the aqueous extract of the Siberian fir bark has d
higher biocide activity against conditionally pathogenic and saprotrophic bacteria ina
comparison with the aqueous extract of the Siberian spruce bark. The antibacterial activity o
aqueous extracts of the studied plants bark is determined by their chemical compositionf
primarily the presence of substances of a phenolic nature. It has been shown that the studied,
extracts mainly contain compounds of quercetin, dihydroquercetin and kaempferol.
