The sugarcane (Saccharum spp) presents economic importance, mainly for tropical regions, being an important Brazilian commodity. However, this crop is strongly dependent on fertilizers, mainly nitrogen (N). This study assessed the plant growth-promoting bacteria (PGPB) associated with sugarcane that could be used as a potential inoculant to the crop. We evaluated the genetic diversity of PGPB i...
The strain BR 3267 is a nitrogen-fixing symbiotic bacteria isolated from soil of semi-arid area of Brazilian Northeast using cowpea as the trap plant. This strain is used as commercial inoculant for cowpea and presents high efficient in nitrogen fixation as consequence of its adaptation potential to semi-arid conditions. We report here the draft genome sequence of Bradyrhizobium sp. strain BR 3...
Plants are generally subjected to a combination of different conditions such as magnetic field and soil bacteria in their life. The present investigation tried to compare the effects and interactions of magnetic field and rhizobial inoculant in alfalfa. A pot experiment was performed under a natural condition by a factorial design to ...
Although Azospirillum strains used in commercial inoculant formulations presents diazotrophic activity, it has been reported that their ability to produce phytohormones plays a pivotal role in plant growth-promotion, leading to a general recommendation of its use in association with regular N-fertilizer doses. In addition, a high variability in the effectiveness of Azospirillum inoculants is st...
Rhizobial inoculants have been used successfully in world agriculture for about 100 years. About 20 million ha crop and pasture legumes are inoculated in the world each year, although that figure could be increased if high-quality inoculants were available to all farmers. The characteristics of a high-quality inoculant relate to the properties of the carrier, the infective (nodulating) and effe...
This study examined the effects of bacterial inoculants on chemical composition and fermentation indices of barley silage. Barley forage (Youngyang) was harvested at 24% dry matter (DM) and wilted to 47.9% DM. The wilted barley forage was chopped to 3-5 cm length and applied with no inoculant (CON), L. plantarum (1×10(10) cfu/g, LP) or Effective Microorganisms (0.5×10(9) cfu/g, EM). Then the fo...
the aim of this study was to investigate the effect of bacterial inoculation on the fermentation and aerobic stability of corn silage and on the dry matter degradability and milk composition when fed to sheep or cows. four male sheep were selected to measure dry matter degradability of uninoculated (ucs) and inoculated (ics) corn silage. milk composition was measured for 22 holstein cows, separ...
We examined the influence of soil aeration state and plant root presence on the comparative survival of wild-type bacteria and isogenic Tn5 (Nir(sup-)) mutants lacking the ability to synthesize nitrite reductase. Two denitrifying Pseudomonas strains with different nitrite reductase types were used. Enumeration of bacteria in sterile and nonsterile soils was based on differential antibiotic resi...
