Azotobacter chroococcum: Utilization and potential use for agricultural crop production: An overview

چکیده
It is important to develop integrated crop production strategies that enhance the productive ability of crops in a sustainable manner for the developing nations worldwide. Intensive farming practice of high yielding crop production is mainly dependent on chemical inputs as fertilizer, pesticide and weedicides. However, excessive use of chemical inputs has negative impact on environment in the form of soil infertility, ground water contamination, imbalance of biological ecosystem and cost inputs. Soil health is an important aspect of productive sustainable agriculture and in recent years maintaining soil quality can reduce the problems of land degradation, decreasing soil fertility through use of advanced technologies in the field of biofertilizers. Biofertilizers can produce mineral nutrients through natural processes of biological nitrogen fixation, phosphate solubilization and also stimulation plant growth through the synthesis of plant growth promoting substances. Thus, in recent years biofertilizers have become an important component of integrated management for enhanced crop production. This paper reviews the facts and observations regarding an important biofertilizer microorganism Azotobacter chroococcum and its potential for crop production based.

Assessment of plant growth promoting activities and abiotic stress tolerance of Azotobacter chroococcum strains for a potential use in sustainable agriculture
This study aimed to select and characterize bacterial strains with multiple plant growth promotion properties able to tolerate drought and salinity stress in order to improve plant growth performance under abiotic stresses. Plant growth promoting activities were evaluated in 106 bacterial strains isolated by soil, compost, lignocellulosic biomasses and food matrices. Two strains A. chroococcum ...
متن کاملProduction of Polyhydroxyalkanoates by Azotobacter chroococcum H23 in Wastewater from Olive Oil Mills (Alpechin)
We describe the production of large amounts of homoand copolymers of polyhydroxyalkanoates (PHAs) by Azotobacter chroococcum strain H23 when growing in culture media amended with alpechin. A. chroococcum grown on NH4+-medium supplemented with alpechin formed PHAs up to 50% of the cell dry weight after 24h. The results show that alpechin supports the growth of strain H23 and also that this waste...

Selection of plant growth-promoting bacteria in sweet sorghum (Sorghum bicolor (L.) Moench) under the effects of salinity
Background Sorghum, a grassy non-halophyte, it is both drought and salinity tolerant, and is considered a promising crop for semiarid regions. During the last 20 years, its culture has expanded in Brazilian production by 780%, reaching 1,928,970 tons in 2009 [1]. Salinization of the soil and lack of rain are increasing constraints in semiarid regions. They predominate in northeastern Brazil. Th...
متن کاملEffect of Rhizobium trifolii, Pseudomonas fluorescens and Azotobacter chroococcum on Growth and Yield of Crismon Clover and Rice in a Rice-Clover Rotation
Cultivation of legume species as the second crop in rotation with rice and using plant growth promoting bacteria can be a good approach to improve rice production sustainability. This experiment was carried out to evaluate the effect of plant growth promoting bacteria on accelerating vegetative growth of crimson clover (Alborz 1) and rice (Hashemi) yield in a rice-based cropping system. A facto...
