title: [The development of bacterial growth stimulants from plants].
abstract: Dried bacterial growth stimulators in the form of water extracts of wild marjoram were developed; they produced a stimulating effect on Escherichia coli and Streptococcus pyogenes Dick 1 and had no influence on the growth of Corynebacterium xerosis 1911. The study aimed at finding out the active principle of the stimulator prepared from marjoram extract revealed that under experimental conditions marjoram extract could be divided into 3 fractions of these: fraction 1 contained terpenic hydrocarbons, fraction 2 contained vitamins and vitamin-like substances, fraction 3 contained phenols, flavonoids, phenolcarbonic and fatty acids. Fraction 3 at a concentration of 0.0001% produced the best effect. The stimulating effect of extracts obtained from lime and aspen leaves, haw berries was demonstrated.
