Study of the Component Structure of the Metabolites of Bacteria Nocardiopsis umidischolae in the Search for Eco-Friendly Plant Protection Agents
2020
The component structure of the suspension and extracts (water-alcohol,
methanol, and hexane) of isolates of Nocardiopsis
umidischolae nos. 2 and 18 strains having high rates of aphicidal
and acaricidal activities and lacking phytotoxicity was studied using the
methods of qualitative tests and thin layer chromatography (TLC). The
composition of the water-alcohol extracts from the actinomycete strains was
analyzed by high performance liquid chromatography (HPLC). The HPLC analysis of
the metabolites of N. umidischolae no. 2
bacteria revealed the presence of isocitric, acetic, fumaric, malic, lactic, and
citric acids. The metabolites of N.
umidischolae no. 18 culture contained isocitric, acetic, fumaric,
and lactic acids.
