Nitrogen Fixation by Yeasts and Other Fungi
Since the epoch making discoveries of Hellriegel~ there have followed in quick succession many series of investigations relative to the hxation of atmospheric nitrogen by living organisms. Especially brilliant are the investigations of Winogradskyt on Clostridium pastorianum and those of Beyerincka on the Azotobacter group, and it is unnecessary here to go into a review of the investigations wh...
متن کاملLegume Growth and Nitrogen Fixation as Affected by Plant Competition for Light and for Soil Nitrogen'
395 ABSTRACT Since the legume responses to environmental factors may be different in grass mixtures than in pure stands, a pot experiment was conducted to evaluate the effects of plant top and root competition on the growth and N fixation of Desmodium intortum, cv. ‘Greenleaf’ grown in association with Setaria anceps, cv. 'Nandi' The plants were grown in deep, narrow pots which provided for ± t...
متن کاملNitrogen Fixation by Ceanothus.
The rapidity of successioni of Ceanothus species in burned-over areas where they are indigenous and the apparent enhancing effect which these species have on the development of other shrubs and ground cover suggests that Ceanothus has a soil-improvement effect and implies the fixation of nitrogen. Nodulation of some species of Ceanothus was observed as early as 1912 (3). Bottomley and also Petr...
متن کاملNitrogen Fixation by Azotobacter vinelandii
Nitrogenase was isolated and purified from wildtype and a tungsten-resistant mutant (LM2) of Azotobacter vinelandii strain OP derepressed on medium containing 1-10 mM W. While the enzyme from the wild-type strain contained the polypeptides of the conventional enzyme, metal analysis of component 1 demonstrated the existence of one atom each of molybdenum and tungsten. Furthermore, the ESR spectr...
متن کاملStudies on Nitrogen Fixation by Blue-green Algae I. Nitrogen Fixation by Anabaena Cylindrica Lemm
RECENT work, particularly that of De (1939), has shown that some blue-green algae are capable of utilizing the free nitrogen of the atmosphere in the synthesis of cell material. Much further work will be necessary, however, before the importance of nitrogen fixation by these organisms in nature can be estimated, our knowledge both of the distribution of the property within the group of the Myxo...
