actinomycetes are interesting as a main producer of secondary metabolites and industrial antibiotics from marine environments. a total of 44 strains of actinomycetes were isolated from caspian sea sediments at a depth of 5-10 m. preliminary screening was done using cross-streak method against 2 gram-positive and 4 gram-negative pathogen bacteria. the most potent strains mn2, mn3, mn38, mn39, mn...

a study was made of the coking of a commercial fresh sulfide ni-mo/al2o3 catalyst in a fixed-bed reactor. the catalyst was coked using different coke precursors in the gas oil under accelerated conditions at temperatures of 400 to 450°c to yield different deactivated catalysts containing 2-20 wt% c. two cases were studied; crushed catalyst without diffusional resistance and extruded pellets wit...
