The Zymomonas mobilis gene encoding phosphoglucose isomerase (pgi) was cloned by genetic complementation of an Escherichia coli pgi mutant. An enzyme assay and sodium dodecyl sulfate-polyacrylamide gel electrophoresis confirmed the presence of excess amounts of phosphoglucose isomerase in E. coli clones carrying the Z. mobilis pgi gene. The pgi gene is present in only one copy on the Z. mobilis...

      In the present study, four carbon sources were tested for the polyester synthesis of Pseudomonas aeruginosa PA01 which is a ubiquitous environmental bacterium and is one of the top three causes of opportunistic human infections. These included linear C8 to C11 carboxylic acids. Octanoic acid, nonanoic acid, decanoic acid and undecanoic acid were added to M1 ...

Abstract Background: Increase of nitrate concentration in water sources is becoming a serious problem in many parts of the world. Nitrogen containing compounds released into environment can create serious problems, such as eutrophication of water sources and hazard potential to human health, because it has potency of causing methemoglubinemia disease and cancer. Between recommended methods, bi...
