Role of Humic Compounds in Viability Prolongation of the Cells of Hydrocarbon-Oxidizing Bacteria

摘要

Addition of humic compounds (9 preparations) to the cultures of hydrocarbon-oxidizing bacteria was shown to result in up to 15-fold increase in the number of viable cells in the cultures stored in the growth media with access to air at 20-25 degrees C. The most oxidized humates exhibited the highest activity in induction of persister formation, which subsequently matured to dormant forms, while unoxidized humates with antioxidant activity supported viability persistence.
