FLOTATION REMOVAL OF CESIUM (I) AND BARIUM (II) …

Sep 08, 2006· Corynebacterium glutamicum grew on resorcinol as a sole source of carbon and energy. By genome-wide data mining, two gene clusters, designated NCgl1110-NCgl1113 and NCgl2950-NCgl2953, were proposed to encode putative proteins involved in resorcinol catabolism.
