The reestablishment of autochthonous shrubs species is an essential strategy for recovering degraded soils under semiarid Mediterranean areas. A field experiment was carried out to assess the effectiveness of an immobilized microbial inoculant (Azospirillum brasilense and Pantoea dispersa) and the addition of organic olive residue (alperujo), for plant growth promotion of Cistus albidus L. and ...

The objective of this study is to verify the population density and the dynamics of tillering in the Marandu palisade grass sward subjected to nitrogen (N) fertilization strategies, characterized by the N supply via urea or bacterial inoculant (Azospirillum brasilense). The treatments comprised of four nitrogen fertilization strategies: (A) Without fertilization, (B) 80 kg N/ha, (C) inoculant (...

Analysis of phylogenomic metrics of a recently released draft genome sequence of the halotolerant, acidophile 'Thiobacillus prosperus' DSM 5130 indicates that it is not a member of the genus Thiobacillus within the class Betaproteobacteria as originally proposed. Based on data from 16S rRNA gene phylogeny, and analyses of multiprotein phylogeny and average nucleotide identity (ANI), we show tha...

The complete 5S and 16S ribosomal DNA (rDNA) sequences of the facultatively chemolithotrophic bacterium Thiobacillus cuprinus and results of a comparison of these sequences with homologous sequences from several proteobacterial species supported affiliation of T. cuprinus with the beta 1 subgroup of the Proteobacteria. T. cuprinus, Thiobacillus intermedius, Thiobacillus perometabolis, and Thiob...

Diverse rhizobia able to nodulate Biserrula pelecinus evolved following in situ transfer of nodA and nifH from an inoculant to soil bacteria. Transfer of these chromosomal genes and the presence of an identical integrase gene adjacent to a Phe tRNA gene in both the inoculant and recipients indicate that there was lateral transfer of a symbiosis island.

The aim of this study was to determine the effects of a bacterial inoculant and chemical additives on nutrient composition, in vitro degradation, total loss, aerobic stability, microbiological quality, and fermentative profile of sugarcane silage. Treatments were distributed to forty-eight mini-silos in a 2 × 4 factorial arrangement: two levels of microbial inoculant (INO, 0 or 4 g/t of fresh s...
