Abstract
The subject invention provides microbe-based products, as well as their use in simultaneously enhancing oil recovery from an oil well while efficiently removing contaminating compositions such as biofilm, scale, paraffin, and/or asphaltenes from oil production equipment and oil-bearing formations. The subject invention can also be used to disperse paraffin and asphaltene precipitates, and to reduce the viscosity of heavy crude oil. The subject invention further provides materials and methods for bioremediation of hydrocarbon-contaminated sites.
