RNAs prepared from particles of ten plant viruses by a new procedure in which detergent and sodium perchlorate were used were compared with RNAs obtained by the standard two-phase phenol technique.… (More)
Ion exchange papers were used to study the adsorption of 32P-labelled rhizobia on defined surfaces. Two strains of Rhizobium japonicum and one each of R. leguminosarum and R. lupini were compared… (More)
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… (More)
Sodium perchlorate in high concentrations will remove from solution the detergent sodium dodecyl sulphate and protein complexed with it. This and the failure of proteins to be precipitated by ethanol… (More)
At low temperatures, bacterial spores and Micrococcus radiodurans show paradoxical changes in sensitivity to the lethal effects of ultraviolet irradiation.
Tissue-cultured cells of soy bean, grown in liquid medium and then transferred to an agar substratum in so-called tissue chambers, showed an affinity for the binding of applied bacteria (Klebsiella… (More)
Induced by soy bean tissue cultures in socalled "tissue chambers", Rhizobium japonicum str. 61-A-96 developed nitrogenase activity separated from the plant cells. The activity proceded for 48 h with… (More)
The lethal effects of solar radiation on frozen Escherichia coli are increased at low temperatures. At the same time there is an increased number of mutations, which may be concerned in speciation.
