“…The area surrounding plant roots, called rhizosphere, is a space richly colonized by actinomycetes. Their high synthesis of antimicrobial compounds and other metabolites gives them a competitive advantage, besides helping with the improvement of soil fertility by promoting plant growth, providing protection against phytopathogens and resisting environmental stresses (15,16). Bacterial endophytes are other important class of microorganisms that help the host develop while using nutrients and shelter provided by the plant cells.…”

The use of fertilizers and chemical pesticides promotes significant improvements in crop development, but some problems and risks associated with them limit their application. An alternative is using biological inputs based on microorganisms, increasing production while combining efficiency and sustainability. Actinomycetes are a group of bacteria belonging to the phylum Actinobacteria, recently re-named Actinobacteriota. They represent important microbial communities in the soils with increasing agricultural applications, especially in the biological control of insect-pest and plant disease and in plant growth promotion. Studies report their promising use as microbiological inoculants by exploring mechanisms to improve plant development, such as biological nitrogen fixation, phosphate solubilization, production of phytohormones, and other biocompounds. In addition, many species produce metabolic pathways that generate high-value antibiotics, extracellular enzymes and secondary metabolites other than antimicrobials, with potential in the control of phytopathogenic fungi, insects, and nematodes. These actinomycetes could be used to formulate novel bioinoculants composed of spores and/or mycelium. Considering that the research in this field is up-and-coming, with significant economic and environmental impacts in the future, this review aims to group the most relevant works that explore the biodiversity of actinomycetes, helping to develop inoculants and biodefensives for more productive and conscious agriculture.

“…Actinobacteria produce a number of bioactive metabolites that are beneficial to both soil and plants. They also have the capacity to act as biocontrol agents [225] , making plants more resistant to biotic and abiotic stresses [225,226] . A study done by Wang et al [227] showed that certain actinobacteria (Streptomyces pactum Act12, S. globisporus Act7, and S. globisporus subsp.…”

“…For instance, Streptomyces violaceusniger YCED9 produces antibiotics such as headache, Geldanamycin, and Guanidylfingine to counteract plant pathogens. Previous studies have demonstrated actinobacteria ability to enhance plant growth and effectively manage plant diseases [226,228,231,232] . Streptomyces strains are primarily recognized for their capacity to act as a biocontrol agent by producing potent volatile compounds, metabolites, and antibiotics that exhibit antipathogenic properties [233] .…”

This article emphasizes the various contributions of actinobacteria to the well-being of human life on our planet. Agrarian virtues begin with the substitution of chemical fertilizers with bio-fertilizing microorganisms which have a versatile potential for the benefit of soil and plants by playing complementary and interconnected roles. Thus, these microorganisms improve soil health through bioremediation phenomena and the elimination of several non-beneficial microorganisms. In agriculture, these microorganisms can be added to compost as inoculants to speed up the composting process and provide an additional source of beneficial microorganisms for the compost-treated soil. Streptomyces and other actinobacteria can also be used as biotechnological sources of herbicides and insecticides. In the medical and therapeutic sectors, this paper emphasizes the potential of actinobacteria, in particular Streptomyces species, in the production of antibiotics, antioxidant, and anticancer agents, opening up avenues for the creation of molecules with high benefits. In biotechnology, these totipotent microorganisms produce enzymes widely used in several industries, generating considerable revenue. Sporadic data accumulated on these types of microorganisms opens up many new avenues for exploiting these natural biocatalytic resources. Papers published in the last decade have exploded the amount of information that can be put to practical use. To maximize the value of these microorganisms, it would be advisable to create common threads between the themes that bring together the areas of expertise where these microorganisms could potentially be exploited. This bibliographical synthesis is a contribution to the development of a targeted database.
