Role of ureolytic activity in Bacillus cereus nitrogen metabolism and acid survival [PDF]
, 2008 The presence and activities of urease genes were investigated in 49 clinical, food, and environmental Bacillus cereus isolates. Ten strains were shown to have urease genes, with eight of these strains showing growth on urea as the sole nitrogen source ...
