Bacterial and archaeal diversity in sediments of west Lake Bonney, McMurdo Dry Valleys, Antarctica.

abstract：:Growth, survival, and pathogenicity of Klebsiella growing in and on environmental foci were examined. Total coliforms present in raw wastes from pulp mills were in excess of 10(5)/ml, and 60 to 80% were Klebsiella. Fecal coliform counts ranged from 10(1) to 10(5)/ml. Klebsiella isolates from industrial effluents and a...
