Sensitivity to heavy metal (HM) exposure has been studied in actinobacterial cultures maintained at the Regional Specialized Collection of Alkanotrophic Microorganisms (acronym IEGM; http://www.iegm.ru/iegmcol ). Possible mechanisms of nonspecific resistance of actinobacteria to HMs are discussed, which may be due to their ecological preferences, alkanotrophy, and ability to synthesize biosurfactants. Hydrocarbon-oxidizing strains have been selected that are characterized by high emulsifying activity and resistance to increased (>250 mM) HM concentrations.
