“…Similar findings were presented by Yu and coauthors [28] and Efe [29], where not all Bacillus strains produced this auxin. The effect of Au on IAA was studied by Panichikkal and co-workers [30]. In their study, gold nanoparticles (AuNPs) synthesized by Bacillus subtilis SJ15 were introduced into the growing medium of Pseudomonas monteilii and Vigna unguiculata.…”

As an adaptation to unfavorable conditions, microorganisms may represent different phenotypes. Azolla filiculoides L. is a hyperaccumulator of pollutants, but the functions of its microbiome have not been well recognized to date. We aimed to reveal the potential of the microbiome for degradation of organic compounds, as well as its potential to promote plant growth in the presence of heavy metals. We applied the BiologTM Phenotypic Microarrays platform to study the potential of the microbiome for the degradation of 96 carbon compounds and stress factors and assayed the hydrolytic potential and auxin production by the microorganisms in the presence of Pb, Cd, Cr (VI), Ni, Ag, and Au. We found various phenotype changes depending on the stress factor, suggesting a possible dual function of the studied microorganisms, i.e., in bioremediation and as a biofertilizer for plant growth promotion. Delftia sp., Staphylococcus sp. and Microbacterium sp. exhibited high efficacy in metabolizing organic compounds. Delftia sp., Achromobacter sp. and Agrobacterium sp. were efficient in enzymatic responses and were characterized by metal tolerant. Since each strain exhibited individual phenotype changes due to the studied stresses, they may all be beneficial as both biofertilizers and bioremediation agents, especially when combined in one biopreparation.

“…Siderophore-based biological control agents are gaining commercial significance as they are safer, do not lead to biomagnification, and also provide iron nutrition to the crops thereby promoting plant growth (Sasirekha and Srividya 2016). Phytohormone indole-3-acetic acid (IAA) is often found among the compounds produced by rhizobacteria and has significant roles in interaction between plants and bacteria (Panichikkal et al 2019). Microbial IAA production acts as one of the key mechanisms that influence plant physiology and growth stimulation during the plant-microbe interaction.…”

Fusarium wilt of banana, caused by Fusarium oxysporum f. sp. cubense (Foc), tropical race 4 (TR4), is one of the most devastating diseases, thus control of this disease is an urgent need in banana production. Streptomyces morookaensis strain Sm4-1986 significantly inhibited mycelial growth and spore germination of pathogen Foc-TR4. Chrome Azurol S assay showed that the strain Sm4-1986 is able to produce siderophores, and spectrometric scan confirmed that the siderophores produced belong to carboxylate-type. Addition of FeCl 3 eliminated the antagonism between the strain Sm4-1986 and Foc-TR4. Inoculation of banana plantlets with strain Sm4-1986 promotes plant growth, which may be mainly due to the production of indole-3-acetic acid (IAA). Application of strain Sm4-1986 to banana plantlets significantly reduced disease severity index and disease incidence of Fusarium wilt. These findings suggest that the Streptomyces morookaensis strain Sm4-1986 could be explored for uses such as biocontrol agents or biofertilizers in banana plantation.
