Capsule degradation in azotobacter
Life Sciences, 1974Abstract Enzymic degradation of Azotobacter capsular polysaccharide by the depolymerases from azotophage lysates of A . vinelandii , and from a strain of A . chroococcum was examined. The molecular size of the capsular polysaccharide was examined by molecular sieve chromatography both before and after exposure to the ...

A field experiment was conducted during two consecutive growing seasons (2013 and 2014) to evaluate the effects of inoculations with Rhizobium and Azotobacter on the growth and yield of two chickpea (Cicer arietinum L.) varieties under saline (5.8 dS m−1)

Derepression of nitrogenase in Azotobacter
Biochemical and Biophysical Research Communications, 1974Abstract When nitrogenase in Azotobacter vinelandii 12837 is repressed by ammonia, the derepression is accelerated by endotoxin or cyclic AMP. The phenomenon appears neither to be a consequence of accelerated ammonia utilization nor altered activity of preformed enzyme. This is a unique example of an effect of endotoxin on a procaryotic system.

Azotobacters have been used as biofertilizer since more than a century. Azotobacters fix nitrogen aerobically, elaborate plant hormones, solubilize phosphates and also suppress phytopathogens or reduce their deleterious effect. Application of wild type Azotobacters results in better yield of cereals like corn, wheat, oat, barley, rice, pearl millet and

Acid Production by Azotobacter vinelandii
Nature, 1963Azotobacter vinelandii has been characterized by its lack of acid production in culture1. In fact, most species of Azotobacter do not form acid, but appear to oxidize carbohydrates completely to carbon dioxide and water2. The notable exceptions to this are the acid-tolerant A. indicum (Beijerinckia indica)3 and A. macrocytogenes4 that are characterized

Electron transport in Azotobacter vinelandii
Biochimica et Biophysica Acta (BBA) - Enzymology and Biological Oxidation, 1966Summary 1. The nature and intracellular distribution of the respiratory enzyme system of Azotobacter vinelandii has been investigated. 2. Whole cells of this organism were found to contain high concentrations of ubiquinone (Q-8) but, in contrast to Azotobacter vinelandii strain O, no menaquinone (vitamin K2) was detected. 3.

Nutritive Qualities of Azotobacter vinelandii
Journal of the American Dietetic Association, 1957The bodies of the bacteria called Azotobacter, when dried, contain 75 per cent protein of good quality. Growing this organism on a commercial scale could conceivably add substantially to the world's supply of protein ...

Reduction of Nitrates by Azotobacter indicum and Azotobacter chroococcum Cultures
Applied Biochemistry and Microbiology, 2002The capacity for denitrification was studied in Azotobacter bacteria, which are free-living nitrogen-fixing obligatory aerobes. Data on nitrate reduction to nitrites and nitric oxide by A. indicum under anaerobic conditions were obtained for the first time for genus Azotobacter.

PREVIOUS attempts at studying the antigens of Azotobacter have met with only limited success. Azo and Yoshida in a brief report1 described complement-fixation by Azotobacter cells in the presence of specific antisera but gave few experimental details. Jensen and Petersen2 obtained an agglutinating antiserum for Azotobacter chroococcum.

Glucose catabolism in Azotobacter vinelandii
Archives of Biochemistry and Biophysics, 1964Abstract The catabolism of glucose in proliferating cells of Azotobacter vinelandii has been examined with respect to the nature and participation of individual pathways. The radiorespirometric method and substrate incorporation studies were used in this investigation.
