Usage of Bacillus and Azospirillum as new eco-friendly microbial consortium inoculants is a promising strategy to increase plant growth and crop yield by improving nutrient availability in agricultural sustainable systems. In this study, we designed a multispecies inoculum containing B. thuringiensis (strain B116), B. subtillis (strain B2084) and Azospirillum sp. (strains A1626 and A2142) to investigate their individual or co-inoculated ability to solubilize and mineralize phosphate, produce indole acetic acid (IAA) and their efect on maize growth promotion in hydroponics and in a non-sterile soil. All strains showed signifcant IAA production, P mineralization (sodium phytate) and Ca?P, Fe?P (tricalcium phosphate and iron phosphate, respectively) solubilization. In hydroponics, co-inoculation with A1626 x A2142, B2084 x A2142, B2084 x A1626 resulted in higher root total length, total surface area, and surface area of roots with diameter between 0 and 1 mm than other treatments with single inoculant, except B2084. In a greenhouse experiment, maize inoculated with the two Azospirillum strains exhibited enhanced shoot dry weight, shoot P and K content, root dry weight, root N and K content and acid and alkaline phosphatase activities than the other treatments. There was a signifcant correlation between soil P and P shoot, alkaline phosphatase and P shoot and between acid phosphatase and root dry weight. It may be concluded that coinoculations are most efective than single inoculants strains, mainly between two selected Azospirillum strains. Thus, they could have synergistic interactions during maize growth, and be useful in the formulation of new inoculants to improve the tropical cropping systems sustainability.

Com o objetivo de otimizar o encapsulamento de AN e analisar sua estabilidade, foi realizada a extração do DNA plasmídial (c-DNA) da bactéria Xanthomonas citri pv. viticola (syn. X. campestris pv. viticola) e um ds-RNA projetado (adiquirido de empresa específica) para silenciar o psilídeo Diaphorina citri, vetor da bactéria que causa o grenning. |
