Asphaltene biotransformation by a novel enzyme thiol peroxidase from Micrococcus sp. IITD107 [PDF]
Applied and Environmental MicrobiologyAsphaltenes are known to cause high density and viscosity in heavy crude oil. The gene for thiol peroxidase was found to be present in five members of the nine-membered bacterial consortium able to biotransform about 75% of asphaltenes.
