Abstract
The present invention relates to the use of microorganisms (biocatalysts), or catalysts derived from these organisms (enzymes), to improve the quality of crude oil and bitumen as an attractive alternative to current upgrading methods. The invention identifies and characterizes the microorganism species, in particular, N. muscorum (UTEX 2209) and Kocuria rhizophilia (ATCC533), that have the capability to biochemically convert organic acids into chemical species that do not possess corrosive properties.
