“…The phylogenetic position of strain SgZ-5 T is shown in Fig. 2 , where A. humicireducens can be grouped as a Azospirillum species, forms a distinct subclade together with A. lipoferum that are known as a biofertilizer widely used for agricultural production [ 13 , 14 ]. The 16S rRNA gene of strain SgZ-5 T is 98% similar to that of A. lipoferum NCIMB 11861 T .…”

The Azospirillum humicireducens strain SgZ-5T, belonging to the Order Rhodospirillales and the Family Rhodospirillaceae, was isolated from a microbial fuel cell inoculated with paddy soil. A previous work has shown that strain SgZ-5T was able to fix atmospheric nitrogen involved in plant growth promotion. Here we present the complete genome of A. humicireducens SgZ-5T, which consists of a circular chromosome and six plasmids with the total genome size of 6,834,379 bp and the average GC content of 67.55%. Genome annotations predicted 5969 protein coding and 85 RNA genes including 14 rRNA and 67 tRNA genes. By genomic analysis, we identified a complete set of genes that is potentially involved in nitrogen fixation and its regulation. This genome also harbors numerous genes that are likely responsible for phytohormones production. We anticipate that the A. humicireducens SgZ-5T genome will contribute insights into plant growth promoting properties of Azospirillum strains.Electronic supplementary materialThe online version of this article (10.1186/s40793-018-0322-2) contains supplementary material, which is available to authorized users.

“…brasilense is a nitrogen-fixing microorganism that colonizes the root. This bacterium also produces growth-promoting substances such as indoleacetic acid (IAA), gibberellins, pantothenic acid, thiamine and niacin, in addition to increasing root density and branching (TAMILSELVI et al, 2016). Positive results with the inoculation of A. brasilense on maize were reported by QUADROS et al (2014) andHUNGRIA et al (2010).…”

The evaluation of plant growth-promoting bacteria in order to increase corn productivity is a biotechnology of global interest. This study evaluated the efficiency of the consortium between P. fluorescens CNPSo 2719(=CCTB03) and A. brasilense Ab-V06 in corn. Four experiments were carried out in four different locations, with a randomized block design and four replications, with the treatments: (1) without inoculation and without application of N coverage; (2) without inoculation and application of 100% of the recommended dose of N in coverage (200 kg ha-1 of N); (3) Azospirillum brasilense + application of 75% of the recommended dose of N in coverage (150 kg ha-1 of N); (4) bacterial consortium of Azospirillum brasilense + Pseudomonas fluorescens + application of 75% of the recommended dose of N in coverage (150 kg ha-1 of N). In all locations, with the use of the bacterial consortium (A. brasilense + P. fluorescens) + 75% of the recommended dose of N in coverage, it was possible to reduce the dose of N in coverage by up to 25% without compromising the productivity of the crop. In this way, it is concluded that the use of the consortium of the two bacteria promotes savings of up to 25% of N fertilization in top dressing and the possibility of using two microorganisms with the capacity to stimulation plant growth with a single application.
