The algJ gene from Azotobacter vinelandii was cloned using a labelled RNA probe representing the coding region of the algE gene from Pseudomonas aeruginosa. DNA sequencing revealed an ORF of 1452 bp encoding a protein of 484 amino acid residues with a calculated molecular mass of 54611 Da. An RNA probe corresponding to algE was also used for Southern hybridization of chromosomal DNA, which show...

Purpose. To investigate effects of biologicals on disease-induced damage to white cabbage plants during the growing period and yield. Methods. Informational/analytical (collection review publications), field research (planning conducting experiments, records plant damage, harvesting accounting yields), phytopathological (isolation identification pathogens), mathematical/statistical (processing ...

In order to Study the efficacy application of green manure as chickpea pre plant, field experiments were carried out in 2007 and 2008 growing seasons. In this research the effects of different strategies for soil fertilization were investigated on grain yield and yield component, minerals, organic compounds and cooking time of chickpea. Experimental units were arranged in splitsplit plots based...

Methods employed in the study of the fluorescent culture filtrates of Azotobacter are described. The use of a fluorescence meter in the characterization of the fluorescent substances elaborated by Azotobacter agile, Azotobacter vinelandii, and Azotobacter macrocytogenes n. sp. is discussed. A. macrocytogenes, a fluorescent species, is included with the two previously reported fluorescent Azotob...

Rhizosphere microorganisms are a heterogenous group of bacteria, including plant growth promoting bacteria, which can improve extent or quality of plant growth direct and indirect. Generally large array of bacteria, including species of Pseudomonas, Azospirillum, Azotobacter, Klebsiella, Enterobacter, Alcaligenes, Arthrobacter, Burkholderia, Bacillus and Serratia have been reported to enhance p...

Biofertilizers are living microorganisms; they themselves are not source of nutrients but can help the plant in accessing the nutrient available in its surrounding environments (Suman et al., 2015). In general, commonly microbes used as biofertilizers may be Azotobacter, Azospirillum, Rhizobium as nitrogen fixing soil bacteria (Verma et al., 2013, 2014; Verma et al., 2015; Verma et al., 2016a);...
