Effect of Metal Ions on Cell Growth and Phenol Degradation of a Thermophilic Strain BF80

Abstract: The effect on the growth and phenol degradation of the thermophilic strain BF80 by seventeen different metal ions were studied. The results showed that the metal ions certainly affected the growth and phenol degradation of the strain BF80. At the concentration of 0.01%, contrasting to the comparison, the growth and phenol degradation of the strain BF80 were restrained intensively by the metal ions of Cu2+, Zn2+, Co2+, Ba2+, Hg2+, Ni2+, Ag+, Al3+. The metal ions of Cr2+ restrained the phenol degradation of BF80 strongly while Cr2+ restrained the growth of BF80 faintly. The metal ions of Sn2+, Fe2+, Fe3+, Pn2+ restrained the growth and phenol degradation of the strain BF80 at a certain concentration, and the effect of inhibition increased with the increase of the concentrations of the metal ions. At the low concentration of Mn2+ or Mo2+, the growth and phenol degradation of the strain BF80 were increased, but if the concentration beyond the 0.1%, the growth and phenol degradation of the strain BF80 were inhibited. At the different concentration of Ca2+ or Mg2+, the growth of the strain BF80 were increased and the phenol degradation were accelerated, but the max rate of phenol degradation by BF80 was not influenced obviously. When the medium was added the mixture of metal ions of Mo2+ and Mn2+, the strain BF80 grew better, but the rate of the phenol degradation was lower than that of single Mo2+ and Mn2+.

微生物学通报 , 2008,
Abstract: The practice of English teaching of microbiology course using the original edition of Microbiology (Prescott LM et al., 5e, 2002) as textbook have been carried out for two years for undergraduate students majoring in Biology. The strengths of this book are comprehensive coverage, flexibility of organizing, and emphasis on the enhancing the overall ability of students. Its content is excellent with fundamental knowledge, systematic arrangement and up-to-date currency, which helps instructor to construct a suitable system in the course structure and curriculum, as well as to enrich the teaching content and to increase teaching effectiveness. The selection of original edition of English textbook in microbiology course is useful to train high-quality biological talents possessing international view and the adaptive ability of globalization process.
