The counting values generally ranged from 104 to 107 cells/L. Thirty-four strains of mercury- tolerant bacteria were isolated from the MPN tubes. They were classified into nine groups according to the characterization tests, including Gram reaction, glucose fermentation, motility and NaCl requirement. Seven groups included strains that were identified as members of Acinetobacter, Alteromonas, Bacillus, Hyphomonas, Lactobacillus, Pseudoalteromonas and Pseudomonas, respectively. The other two groups included halophilic, Gram-positive strains that were not identified to the generic level; one group produced orange or yellow colonies on agar plates while colonies of the other group were white (opaque or translucent).application/pdf122156 bytesapplication/pdfzh-TW國立臺灣大學海洋研究所汞耐受性細菌mercury-tolerant bacteriareporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/14821/1/912313B002327.pdf
