| compositions of microbial communities associated with oil and water in a mesothermic oil field. | samples of produced water and oil obtained from the enermark field (near medicine hat, alberta, canada) were separated into oil and aqueous phases first gravitationally and then through centrifugation at 20°c in an atmosphere of 90% n(2) and 10% co(2). biomass that remained associated with oil after gravitational separation (1×g) was dislodged by centrifugation at 25,000×g. dna was isolated from the aqueous and oil-associated biomass fractions and subjected to polymerase chain reaction amplifica ... | 2011 | 22038128 |
