“…Other works of the same research group revealed that these same isolates are growth promoters in rice, soybean and bean crops, antagonists to some phytopathogens such as M. oryzae and B. oryzae and resistance inducers. (Filippi et al 2011;Sousa et al 2017;Côrtes et al 2015;Nascente et al 2017;Sperandio et al 2017;Arriel-Elias et al, 2018;Arriel-Elias et al 2019;Silva et al 2020;Rezende et al 2021). However, complete genome characterization and chemical characterization of the metabolites of both bacterial isolates had not been performed so far.…”

The objective of this work was to optimize the extraction process and application of bacterial extracts of Bacillus sp. and Serratia sp. in leaf blast control (Magnapothe oryzae) and brown spot (Bipolaris oryzae) in rice culture. The work was divided into three stages: 1) Bacterial obtaining extracts through liquid-liquid extraction 2) Antagonistic capacity of bacterial extracts to M. oryaze and B. oryae 3) Suppression of brown spot (A1) and leaf blast (A2) in greenhouse. The bacterial isolates in present study were identified as Bacillus sp. (BRM32110) and Serratia marcescens (BRM32113). The crude extract of both isolates at different extraction times 6, 16, 24, 48 and 72 hours reduced the growth of colonies of M. oryzae and B. oryzae by up to 92% and 28%, respectively. The extracts that showed highest inhibition of colony growth were those obtained after 6 and 16h of incubation and were selected for subsequent assays. These, for both isolates were able to reduce conidia germination by up to 91% and apressorium formation of M. oryzae by up to 93%. In green house, A1 the treatment that stood out was the extract of Bacillus sp. (16h) with 6.7% of leaf area affected and in A2 the treatment S. marcescens extract (16h) stood out with only 7.6% of leaf area affected with brusone when compared to control. The use of extracts of Bacillus sp. and Serratia marcescens was efficient in reducing the severity of brown spot and leaf blast in rice crop.

“…In recent decades, Brazilian production has advanced in using sustainable technologies; however, significant challenges are encountered, especially those associated with climate change (SANTOS et al, 2022). Thus, investment in research, development, and innovation is essential to reduce the intensive use of synthetic inputs and cultural management that negatively impact the environment (SILVA et al, 2020b).…”

“…Recent studies show the beneficial effects of multifunctional microorganisms in increasing shoot dry biomass and productivity of soybean (SILVA et al, 2020b;CHAGAS JUNIOR et al, 2022) and common bean (Phaseoulus vulgaris) (REZENDE et al, 2021a); growth promotion of rice (Oryza sativa L.) (FERNANDES et al, 2021;PARRALES et al, 2022) and accumulation of N in maize plants (Zea mays) (MORENO et al, 2021). In addition, the use of different beneficial microorganisms at the same time, defined as coinoculation or consortium of microorganisms, has been gaining market share, since it adds different mechanisms of action, producing potential synergistic effects, compared to the use of isolated microorganisms (FLAUZINO et al, 2018).…”

The use of multifunctional microorganisms (MM) directly benefits the growth and development of plants due to the production of phytohormones and siderophores, supply of nutrients, and assimilation of atmospheric nitrogen (N2), as well as, indirectly, by protecting plants against pathogens. In this way, the search for sustainable agricultural systems is of great importance in searching for cultivation technologies that provide productive increments and minimize production costs and negative environmental impacts. The study aimed to determine the effect of multifunctional microorganisms on gas exchange, grain yield, and production components in soybean plants. In the field experiment, 2019/2020 harvest, a randomized block design was used, with 32 replications. Soybean plants were treated with a consortium of microorganisms Serratia marcensens (BRM 32114) + Bacillus sp. (BRM63573), and, as a control, soybean plants were treated without intercropping. Soybean plants treated with microorganisms showed an increase in photosynthetic rate (16.65%), stomatal conductance (37.50%), the internal concentration of CO2 (10.36%), a mass of 100 grains (4.04%), and yield of grains (14.83%) about untreated plants. Therefore, using a consortium of multifunctional microorganisms, combining multiple functionalities from different microorganisms, shows the potential to increase the agronomic performance of soybean plants. Co-inoculation technology appears as a strategic component of achieving sustainable agriculture.

“…Studies have shown the ability of benefic microorganisms to promote plant development, specifically Pseudomonas in wheat and soybean (Afzal et al, 2010;Karimzadeh et al, 2020;Shirmohammadi et al, 2020), Bacillus strains on millet, corn and oil palm (Ribeiro et al, 2018;Lima et al, 2020, Sousa et al, 2020, Trichoderma in soybean (Bononi et al, 2020), arbuscular mycorrhiza in rice, corn and tomato (Zhang et al, 2016;Saia et al, 2020), among others. Also, these microorganisms, in most cases, are of the "multifunctional" type and can bring benefits to plants through multiple mechanisms of direct and indirect stimulation (Sobral et al, 2018;Silva et al, 2020), with the capacity to fix atmospheric nitrogen (Döbereiner, 1997), potassium solubilization (Basak et al, 2022), siderophore production (Yadav et al, 2020) and mitigation of biotic and abiotic stresses (Leite et al, 2019;Wang et al, 2020;Oliveira et al, 2021).…”

Microorganisms in the soil and rhizosphere can release part of the total phosphorus in the soil through solubilization, mineralization, and an increase of the root absorption surface. The ability of phosphate solubilizing bacteria and mycorrhizal fungi to promote higher yield and profitability in co-inoculated soybean was investigated. For this purpose, field and greenhouse experiments were conducted in the years 2020 and 2021 in Brazil. In the field, the first factor was composed of microorganism application on soybean (simple inoculation with Bradyrhizobium; co-inoculation with Bacillus strains; co-inoculation with arbuscular mycorrhiza), and the second factor consisted of the application or not of phosphate fertilizer (0 and 100 kg ha -1 of P 2 O 5 ). In the greenhouse, treatments of the first factor were maintained with 50 % of the phosphate fertilization and one treatment added (standard inoculation with 100 % of the fertilization). Plant growth, roots, nodules, leaf nutrition, yield, and profitability were evaluated. In 2020, co-inoculation increased plant height, the number of pods, grains, and profitability index. The co-inoculation with Bacillus strains and arbuscular mycorrhiza promoted yield increase only associated with phosphate fertilization, by 813 and 761 kg ha -1 compared to standard inoculation, respectively. In 2021, there were increases for pods, grains, yield, gross profit, net income, and profitability index. Co-inoculation with Bacillus strains and arbuscular mycorrhiza promoted increased soybean yield and profitability, confirming itself as a sustainable technology for Brazilian soybean fields.
