Screening for mutants of Rhizobium japonicum with defects in nitrogen fixing ability.

Zeitschrift fur Naturforschung. Section C, Biosciences - 1 Jan 2000

Hörcher R, Wilcockson J, Werner D

Abstract excerpt

Mutants of Rhizobium japonicum with reduced ex planta nitrogenase activity could be isolated with high frequency by direct screening of ultra-violet mutagenized bacteria growing as spots on the surface of an appropriate agar medium permitting derepression of nitrogenase synthesis. Small glass chambers fitted with a serum cap were pushed into the agar around each spot of growth, forming a small enclosed gas space...
