Improved technique for isolation and identification of Sphaerotilus.

Managanese oxidation by Sphaerotilus discophorus.

Johnson, A. H. (Washington State University, Pullman), and J. L. Stokes. Manganese oxidation by Sphaerotilus discophorus. J. Bacteriol. 91:1543-1547. 1966.-Cell suspensions of Sphaerotilus discophorus in 0.02 m potassium phosphate buffer (pH 7.2) readily oxidized MnSO(4) to dark-brown manganic oxide. The latter appeared to be MnO(2), since its color was the same as MnO(2) and, like the latter, ...

Requirement for Revision of Virology Education for Medical Students

Background: Medical education should be considered as a dynamic process. If necessary, the program should be changed. Considering rapid advantages in the field of virology, it seems to be necessary to review and change the virology course of medical students. Therefore we decided to analyze the view of Iranian medical students of the quantity and quality of virology course. Methods: Medical stu...

Factors Affecting Filamentous Growth of Sphaerotilus natanst

GAUDY, ELIZABETH (University of Illinois, Urbana), AND R. S. WOLFE. Factors affecting filamentous growth of Sphaerotilus natans. Appi. Microbiol. 9:580-584. 1961. Filamentous growth in cultures of Sphaerotilus natans can be measured and compared with total growth by a standardized procedure of winding filaments around an inoculating needle. Filaments and residual growth are then separately wash...
