Abstract:
A bacterial mixture usable in an inoculum usable in a bioremediateion method for accelerated biological degradation of petroleum hydrocarbons in a sea ice-covered polar region includes a plurality of isolated cold-adapted autochthonous bacterial strains. Each of the bacterial strains has petroleum hydrocarbons degrading activity at an ambient temperature of −3° C. and each has a different temperature tolerance range, a different salinity tolerance range, a different petroleum hydrocarbons degradation spectrum, and a different capacity to emulsify oil.
