Manures for Organic Crop Production
Livestock manures are an important resource in sustainable and organic crop production. This publication addresses the problems and challenges of using both raw and composted manures and discusses some of the solutions. It also deals with guano, a similar material. Manures for Organic
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 کاملDissociation Constant in Nitrogen Fixation by Azotobacter
6 Dodge originally used "A" and "a" to designate the two sex types in Neurospora crassa. Lindegren later substituted the symbols "+" and "-" for these. Because of the desirability of using the symbol + for the normal allele of a gene and also to designate a positive experimental result, we prefer Dodge's original designations. 4 Neither conversion of pimelic acid to p-aminobenzoic acid by the n...
متن کاملCorrelation between nitrogen fixation rate and alginate productivity of an indigenous Azotobacter vinelandii from Iran
BACKGROUND AND OBJECTIVES Azotobacter vinelandii, a gamma-proteobacterium, is an obligate aerobic free-living gram-negative soil bacterium capable of fixing nitrogen. Oxygen transfer rate into the cell is reduced by the increase of alginate concentrations during the course of A. vinelandii cultivation. This phenomenon provides a low intracellular oxygen concentration needed for nitrogenase acti...
متن کاملSymbiosis between Chlorella Sp. and Azotobacter Chroococcum and Nitrogen Fixation
Alfred Koch has given considerable attention to the subject of nitrogen fixation by bacteria as resulting from their symbiosis with alga~. Many others have also investigated various features of this problem. In spite of all this there are numerous questions which remain unsolved. The use of soil cultures for such studies is objectionable on account of the soil's complexity, its variety of flora...
