Several strains ofEscherichia coli, containing plasmids that ranged in size from 3.9 to 96 kb, were inoculated into soil at 104–105 cells/g soil. The initial total bacterial population was approximately 5×107 cells/g soil, and the gram-negative bacterial population ranged from 105 to 106 cells/g soil. Changes in various populations were followed on selective media, and as few as 1 to 20 introduced colony forming units (CFU)/g soil could be detected. The introduced strains either remained at… CONTINUE READING
