Forty-eight mutants unable to reduce nitrate were isolated from "cowpea" Rhizobium sp. strain 32Hl and examined for nitrogenase activity in culture. All but two of the mutants had nitrogenase activity comparable with the parental sttain and two nitro

Summary Analysis of a range of antigens by comparative immune diffusion, from wells located at the interface between gels containing 0.75% agar and 3% gelatin respectively, suggests that the formation of immune precipitates in gelatin is selective an
