title: [Effect of physiological factors on biosynthesis of urease in Bacillus spp].
abstract: In this study, urea was shown to be the inducer of the urease enzyme of the soil isolate Bacillus spp. The extracellular urease enzyme production was repressed in UGT cultures containing ammonia, ammonium chloride or tryptophane and in nutrient broth cultures. The optimal urease production culture conditions were determined as pH: 7.0, 30 degrees C and 150 rpm.
