“…The positive effects of these bacteria on the plant are consistent with literature data (Dobbelaere et al, 2003;Mantelin et al, 2006) suggesting that the stimuli to plant growth are always correlated with remarkable changes in root morphology, such as increased length of lateral roots and number of hairs (Mantelin and Touraine, 2004;Vacheron et al, 2013). Several authors attribute the increase in root development in inoculated plants to the release of auxin by bacteria (Bhattacharjee et al, 2008;Dobbelaere et al, 2003;Mantelin and Touraine, 2004). Knowing that Kosakonia sp.…”

“…Studies about the interaction of endophytes with their host plants are important to understand the ecological relevance of this relationship (Hardoim et al, 2008). In addition to the possibility of making fixed nitrogen available to the plant, either through cell death or active release of nitrogenous compounds, diazotrophic bacteria can act as biocontrol agents and can release phytohormones such as indole-3-acetic acid, cytokinins and gibberellins (Bhattacharjee et al, 2008;Ferrara et al, 2012).…”

The present study investigates the strain Kosakonia sp. ICB117, an endophytic, N 2 -fixing bacterium that belongs to a genus recently described. The bacteria were isolated from sugarcane stalks (Saccharum sp. variety SP791011) and inoculated into other sugarcane plants of the same variety. The effect of inoculation on sugarcane growth was then studied in the presence or absence of nitrate supplementation (10 mM). The following plant growth parameters were analyzed: biomass, plant height and number of leaves. Furthermore, CO 2 assimilation and the C and N content of plants were also determined, as was the size of the endophytic bacteria population resulting from the inoculation. The findings showed that inoculation with bacteria (both with or without additional nitrate) led to an increase of plant biomass, CO 2 assimilation, total C and N in the roots, and the number of leaves. In addition, the polyamine putrescine and indole-3-acetic acid were actively released by the bacterium in in vitro assays and might be released in internal plant tissues as well, resulting in plant growth promotion. In conclusion, inoculation of sugarcane with Kosakonia sp. ICB117 increased the efficiency of the plant's metabolism.

“…Applied endophytic bacteria produce ACC deaminase that stops the production of ethylene by degrading the ACC. Bhattacharjee et al (2008) observed that production increase in plant biomass of rice cultivars due to ACC deaminase and IAA by plant growth promoting rhizobacteria upon inoculation. In this study both bacterial strains Bulkholderia phytofirmans (PsJN) and Enterobacter (MN17) produced ACC deaminase and IAA.…”

Micronutrient malnutrition caused by inadequate dietary intake is a global nutritional problem of more than half of world's population. Fortification is expensive while biofotification is a natural approach and considered better than fortification. Biofotification of wheat with micronutrients especially zinc (Zn) and iron (Fe) is a relatively new public approach to control deficiencies of these nutrients in flour/diet in developing countries. This research study is comprised of results of field experiment to examine the effects of foliar feeding of micronutrients along with endophytic bacteria on growth, yield and nutrient uptake of wheat. Compared with control (without foliar feeding of micronutrients), foliar application on wheat with endophytic bacteria increased the plant height, leaf area, spike length and plant biomass by 13.53, 41.67, 55.07 and 42.50% respectively. It was observed that Zn and Fe concentration enhanced in grains up to 37.93 and 10.14% respectively with the combine application of micropower and endophytic bacteria. These results elucidate that foliar feeding of micronutrients effectively biofortified wheat grains. Furthermore, foliar feeding of micronutrients along with endophytic bacteria could be used as an easy, quick and cost-effective approach to enrich wheat flour with health essential micronutrients for correcting malnutrition.

“…The nitrogen-fixing and phosphate-solubilizing bacteria are among the important bacteria in the soil, they play an important role in the nitrogen and phosphorus availability in the soil, and consequently on soil fertility. The bacterial nitrogen fixation phenomenon is an alternative to the high use of chemical fertilizers (Bhattacharjee et al, 2008).…”

The presence of residual pesticides in the soil affect the microbial Communities, as well the continuous use of pesticides exacerbates this problem. Glyphosate is one of the most used herbicides in the world. Up to date several studies have evaluated the tolerance and resistance of bacteria to glyphosate. Nitrogen-fixing bacteria play an important role in soil fertility; thus, the alteration of these bacterial communities decrease soil fertility. The objective of this study was to evaluate the effect of glyphosate application on four bacterial strains Pantoea agglomerans, Rhizobium nepotum, Rhizobium radiobacter, and Rhizobium tibeticum. Glyphosate was applied as the sole source of carbon at the rate (0 g/l, 0.5 g/l, 1g/l, 3g/l, 6g/l and 12 g/l) with two methods. Microbial growth was measured by the Colony Forming Units (CFUs /ml) method. Comparing with the control, our results showed that the growth of the four strains decreased by increasing the concentration of glyphosate. The four strains have shown resistance to glyphosate in the direct enrichment compared to the continued enrichment method. Comparing strains with each other, Rhizobium radiobacter is the most resistant strain to glyphosate.
