“…Silva et al, 2020). Co-inoculation is an agricultural practice that aims to optimize and improve plant development by associating different multifunctional microorganisms (Korber et al, 2021). As a result, the plant may experience greater initial development with positive effects on the crop's grain yield (Silva et al, 2022a).…”

A inoculação e coinoculação do arroz de terras altas com rizobactérias multifuncionais pode promover o crescimento das plantas, especialmente do sistema radicular. Assim, este estudo teve como objetivo avaliar o efeito da inoculação e coinoculação com Azospirillum sp. e Bacillus sp. no desenvolvimento inicial do arroz de terras altas. O experimento foi conduzido em delineamento inteiramente casualizado com 4 tratamentos e 10 repetições, totalizando 40 parcelas. Os tratamentos foram: 1) Ab-V5 (Azospirillum brasilense), 2) BRM 63573 (Bacillus sp.), 3) coinoculação de Ab-V5 + BRM 63573 e 4) controle (sem rizobactérias). A inoculação e coinoculação com as rizobactérias multifuncionais Ab-V5 e BRM 63573 proporcionaram efeitos positivos no desenvolvimento inicial do arroz de terras altas. A inoculação com o isolado BRM 63573 teve efeitos significativos no comprimento da raiz, parte aérea e biomassa total, enquanto a inoculação com o isolado Ab-V5 teve efeitos significativos no comprimento da raiz e produção de raiz e biomassa total. O tratamento com coinoculação teve efeitos significativos em variáveis como diâmetro, volume e superfície total de raiz e biomassa de raiz e total. O tratamento controle (sem rizobactérias multifuncionais) apresentou os piores resultados para a maioria das variáveis analisadas.

“…Similar results were found in the present study, indicating that co-inoculation can be studied as a good strategy to promote plant growth. Therefore, in order to promote sustainable management in the production of soybeans or other crops, studies are needed to identify microorganisms capable of improving the plant's defense and stimulating the acquisition of nutrients(Kang et al 2019;Pranaw et al 2020;Korber et al 2021).…”

Bacteria of the genus Bacillus are ubiquitous in nature and produce several antimicrobial compounds, being increasingly used in plant biocontrol. The objective of this study was to identify the bacterium isolate Bacillus sp. 1.4 at the species level and study its bioactive properties prospecting a potential in agricultural application. The bacterial isolate was identified as belonging to Bacillus altitudinis by 16S rRNA gene sequence analysis and genomic metrics. The antimicrobial substance extracted with butanol inhibited Listeria monocytogenes ATCC 7644 and Bradyrhizobium japonicum CT 00345 with inhibition halos of 12 and 13 mm, respectively. In the exopolysaccharide production assay, B. altitudinis1.4 presented a negative result and in the evaluation of motility through the swarming assay, 90 mm halos were observed in both agar concentrations (0.3 and 0.7%) for up to 72 h of incubation. Genomic analysis revealed genes potentially coding for features that might both be beneficial for plants and improve the competition of B. altitudinis 1.4 in soil. This bacterium was able to solubilize inorganic phosphate, coexist with B. japonicum CT 00345, and form more biofilm when grown together. Based on the results found and with new tests to be performed, it is suggested that the B. altitudinis 1.4 isolate could be a candidate for plant growth promoter.
