Abstract

The increasing demand for using microorganisms in agriculture to improve food production requires constantly assessing microbial diversity. This study aimed to investigate the biochemical properties of individual and combined multifunctional microorganisms, as well as to identify potential applications in biotechnology or agriculture. The experiment comprised 29 treatments, with 7 single and 21 combined microorganisms: M01 (Serratia marcescens), M02 (Bacillus toyonensis), M03 (Phanerochaete australis), M04 (Trichoderma koningiopsis), M05 (Azospirillum brasilense), M06 (Azospirillum sp.), M07 (Bacillus sp.), M08 to M28 (combination among these microorganisms) and M29 (control - no microorganisms). All the single and combined treatments assimilated nitrogen, produced siderophores and indoleacetic acid and solubilized phosphate. Only the treatments M04, M13 and M26 produced HCN. Additionally, all treatments, except for M03, produced biofilm. Only M03, M07, M09, M10, M12 and M13 solubilized potassium.

KEYWORDS: Bacteria isolates, multifunctional microorganisms, nitrogen assimilation.
