Phenotypic characterization of a tungsten-tolerant mutant of Azotobacter vinelandii.

Journal of bacteriology - 1 Feb 1996

Premakumar R, Jacobitz S, Ricke S C, Bishop P E

Abstract excerpt

A tungsten-tolerant mutant strain (CA6) of Azotobacter vinelandii first described in 1980 (P. E. Bishop, D. M. L. Jarlenski, and D. R. Hetherington, Proc. Natl. Acad. Sci. USA 77:7342-7346, 1980) has been further characterized. Results from growth experiments suggest that both nitrogenases 1 and...
