Fig. 1From: Asphaltene biotransformation for heavy oil upgradationAsphaltene biotransformation at shake flask level. a Growth profile of consortium in seven weeks growing cell experiment in the presence of both asphaltene and sucrose where the latter is used as primary carbon source. b Percentage asphaltene biotransformation by consortium with respect to controls in seven weeks growing cell experiment. The left bar represents asphaltene alone and the right bar represents asphaltene and sucrose where the latter serves as primary carbon sources. c Growth profile of consortium in 3Â weeks growing cell experiment with higher inoculum size in the presence of both asphaltene and sucrose where the latter is used as primary carbon source. d Percentage asphaltene biotransformation by consortium with respect to controls in three weeks growing cell experiment with higher inoculum. The left bar represents asphaltene alone and the right bar represents asphaltene and sucrose where the latter serves as primary carbon sourcesBack to article page
