[ 1 ] - Bacterial diversity determination using culture-dependent and culture-independent methods

Mud volcanoes are taken into consideration by geologists and oil industry experts have given their association with oil and gas reserves and methane greenhouse gas production in hydrosphere and atmosphere. Gomishan mud volcano phenomenon in the southeastern edge of the Caspian Sea, given its oil and gas resources, has been studied by some geologists in terms of geology and tectonics but not in ...

[ 2 ] - Optimization of factors affecting on sulfide oxidation from synthetic spent caustic by Haloalkaliphilic Thioalkalivibrio versutus by focus on sodium ion effect: Application of response surface methodology

In the present study, the effects of four factors including initial sulfide concentration (mg l-1 ), agitation speed (rpm), amount of inoculums (%) and sodium concentration (mg l-1) on removal efficiency (%R) and yield of sulfate production by Thioalkalivibrio versutus from synthetic spent caustic were investigated. For this purpose, experiments are designed by design of experiments (DOE) and R...
