Degradation of crude oil by fungal enzyme preparations from Aspergillus spp. for potential use in enhanced oil recovery

摘要

BACKGROUNDMicrobial enhanced oil recovery is a potential technology to enhance crude oil recovery from depleted oil reservoirs and solve stagnant petroleum production. Relevant studies have mainly focused on the use of bacteria, with less attention paid to the potential of fungi. In this study, the efficiency of fungal extracellular enzymes for crude oil degradation and their feasibility for use in enhanced oil recovery were evaluated.
