Buried hydrocarbon deposits, such as liquid petroleum, represent an abundant source of reduced carbon for microbes. It is not surprising therefore that many organisms have adapted to an oily, anaerobic life deep underground, often at high temperatures and pressures, and that those organisms have had, and in some cases continue to have, an effect on the quality and recovery of the earth’s dimini...

The injection of seawater into a hydrocarbon reservoir (seawater flooding), as an oil recovery method, triggers microbial souring, through which microorganisms consume sulfate ions and produce hydrogen sulfide, is hazardous, corrosive, detrimental to the environment if enters production wells. A strategy mitigate this problem add nitrate or nitrite seawater, also known treatment. This study inv...

Protein from oil seed meal is usually prepared by dispersing the protein at a pH more basic than its isoelectric point, separating the undispersed material, and precipitating the protein by lowering the pH to about the isoelectric point. The increase in pH is ordinarily accomplished by addition of base to the meal suspension, while lowering of the pH is effected by addition of acid, frequently ...
