“…like those isolated in this study can be used as probiotics in future studies to suppress the growth of C. immitis in soils of California. However, it has to be confirmed in situ that these antagonists will also be effective against the pathogen in its natural habitat and that the benefit of a biocontrol approach will outweigh any potential negative influences on other soil inhabitants, as well as plants, animals, and humans who reside in the area [84,85]. Furthermore, it should be considered that Coccidioides strains might vary in their ability to withstand microbial antagonism.…”

Valley Fever on the Rise—Searching for Microbial Antagonists to the Fungal Pathogen Coccidioides immitis

The incidence of coccidioidomycosis, also known as Valley Fever, is increasing in the Southwestern United States and Mexico. Despite considerable efforts, a vaccine to protect humans from this disease is not forthcoming. The aim of this project was to isolate and phylogenetically compare bacterial species that could serve as biocontrol candidates to suppress the growth of Coccidioides immitis, the causative agent of coccidioidomycosis, in eroded soils or in areas close to human settlements that are being developed. Soil erosion in Coccidioides endemic areas is leading to substantial emissions of fugitive dust that can contain arthroconidia of the pathogen and thus it is becoming a health hazard. Natural microbial antagonists to C. immitis, that are adapted to arid desert soils could be used for biocontrol attempts to suppress the growth of the pathogen in situ to reduce the risk for humans and animals of contracting coccidioidomycosis. Bacteria were isolated from soil samples obtained near Bakersfield, California. Subsequently, pairwise challenge assays with bacterial pure cultures were initially performed against Uncinocarpus reesii, a non-pathogenic relative of C. immitis on media plates. Bacterial isolates that exhibited strongly antifungal properties were then re-challenged against C. immitis. Strongly anti-C. immitis bacterial isolates related to Bacillus subtilis and Streptomyces spp. were isolated, and their antifungal spectrum was investigated using a selection of environmental fungi.

“…Las comunidades microbianas en los suelos conducen entre 80 y 90% de los procesos biológicos desarrollados en el suelo (Bajsa et al, 2013), debido a sus múltiples nichos ecológicos, entre los que destacan la mitigación de alteraciones exógenas, promoción de crecimiento vegetal, actividad de biocontrol, ciclaje de nutrientes, producción de biomasa vegetal, estructura y fertilidad del suelo, la degradación de compuestos tóxicos, entre otros (Delgado-Baquerizo et al, 2016).…”

Numerosas especies vegetales de interés agrícola establecen simbiosis con microorganismos edáficos, tal es el caso de microorganismos promotores del crecimiento vegetal; los cuales proporcionan grandes beneficios debido a que ayudan a disminuir el uso excesivo de fertilizantes y pesticidas utilizados en la producción agrícola. Actualmente, la agricultura mexicana busca alternativas de fertilización amigables con el medio ambiente. Es por ello que las prácticas de agricultura sostenible solamente pueden ser exitosas cuando los productores tienen todos los medios para implementarlas adecuadamente. El presente ensayo aborda temas sobre las consideraciones y retos para el desarrollo de una agricultura sostenible en México, mediante el uso de microorganismos benéficos, y presenta el panorama actual y futuro sobre su uso tomando en cuenta el beneficio para el productor.

For decades, the surging demand for agricultural produce to alleviate hunger has spurred extensive research into novel and sustainable agricultural practices. Given the detrimental environmental impact of some contemporary agricultural methods, this paper underscores the potential of microbial inoculants as environmentally friendly tools for achieving sustainable agriculture. This narrative review evaluates the use of microbial inoculants in various agricultural practices such as monocropping, crop rotation, and intercropping, contrasts their effectiveness to synthetic agricultural compounds, and highlights potential limitations and strategies for their mitigation. The review reveals that microbial inoculants, as renewable, eco-friendly, crop-supportive, and cost-effective alternatives to synthetic agricultural compounds, hold immense promise for sustainable agriculture. The study concludes with a call for greater emphasis on the use of microbial inoculants, encouraging their broader adoption by farmers to promote sustainability in agriculture.
