“…Numerous species of the genus Paecilomyces produce a wide variety of secondary metabolites with different chemical structures and diverse biological activities, such as herbicidal [ 45 ], insecticidal [ 46 , 47 ], bactericidal [ 48 ], fungicidal [ 49 ], nematicidal [ 50 , 51 , 52 ] or cytotoxic [ 53 ]. There are also descriptions of metabolites with antitumour activity [ 54 , 55 ] or enzyme inhibitors, such as Paecilomide, which acts as an acetylcholinesterase inhibitor and can be used to control human diseases such as Alzheimer’s [ 56 ].…”

Incorporating beneficial microorganisms in crop production is the most promising strategy for maintaining agricultural productivity and reducing the use of inorganic fertilizers, herbicides, and pesticides. Numerous microorganisms have been described in the literature as biological control agents for pests and diseases, although some have not yet been commercialised due to their lack of viability or efficacy in different crops. Paecilomyces is a cosmopolitan fungus that is mainly known for its nematophagous capacity, but it has also been reported as an insect parasite and biological control agent of several fungi and phytopathogenic bacteria through different mechanisms of action. In addition, species of this genus have recently been described as biostimulants of plant growth and crop yield. This review includes all the information on the genus Paecilomyces as a biological control agent for pests and diseases. Its growth rate and high spore production rate in numerous substrates ensures the production of viable, affordable, and efficient commercial formulations for agricultural use.

“…This species has been described as a biological control agent (BCA) against nematodes [6,7], trematode eggs [8] and phytopathogenic fungi, such as Biscogniauxia mediterranea, Fusarium moniliforme and Phytophthora cinnamomi [9], Pyricularia oryzae [10], Fusarium graminearum [11] and Magnaphorte oryzae [12], among others, that function through their raw extracts, secondary bioactive metabolites or their mycelia. P. variotii produces metabolites with herbicidal [13] and insecticidal [14] activity and has been reported to control infections caused by pathogenic bacteria in fish [15] and humans [9]. In turn, this fungal species has even been shown to degrade aromatic compounds [16,17], in addition to removing ammonium from synthetic media and reducing ammonia emissions from chicken manure.…”

In the present study, P. variotii, an endophytic fungus isolated from plant roots from the Cabo de Gata Natural Park (Parque Nacional Cabo de Gata—Spain), was tested to determine the effect on the growth promotion of tomato and pepper seeds and seedlings. For these purposes, germination trials in a laboratory and two experiments in a commercial nursery and greenhouse conditions were performed. The P. variotii isolate has shown a high ability to produce siderophores and IAA, but low ability to solubilize P. High values for germination percentage, seedling vigor, root and shoot length were obtained by P. variotii on tomato and pepper against control. P. variotii applications resulted in improved most of the growth parameters evaluated, for both horticultural crops, with the best results in the development of pepper seedlings. The application of a higher dose of P. variotii improved most of the morphological parameters and the Dickson quality index (DQI) value in tomato in seedlings and plants. The establishment of the endophytic fungus at the root enabled its biostimulant effects to persist after transplantation without any additional application. Few studies have analyzed this species as a biostimulant. The positive results from the tests showed its high potential. The application of this isolate can be of enormous benefit to horticultural crops for its high reproductive and establishment capacity.

“…También, estas dos especies presentan la ventaja de poder crecer a altas temperaturas (70ºC) y sobreviven hasta 20 minutos a en el rango de 80 a 90ºC, por lo que pueden ser utilizados en procesos biotecnológicos que requieren estas temperaturas, pero también presentan un riesgo para la industria alimenticia porque su eliminación es tediosa aún luego de pasteurizar los productos.

El cultivo de la caña de azúcar contribuye a la economía nicaragüense generando el 6.9% del PIB nacional en 2016. Actualmente, está en riesgo el crecimiento de la industria azucarera y su transformación en una biofabrica, tanto por las malas prácticas agrícolas (uso excesivo de agroquímicos y degradación del suelo) como por los efectos del cambio climático, que van desde sequías hasta enfermedades y plagas emergentes. Una de las alternativas más prometedoras para enfrentar la problemática, es el conocimiento de los microorganismos nativos asociados a los principales cultivos (patógenos y benéficos) y poder tomar decisiones de manejo acertadas. En este trabajo, aislamos éstos microorganismos, los identificamos a nivel de ADN y obtuvimos información de su función y relación con el cultivo, constituyendo una base de datos biológica que en adelante será utilizada para el desarrollo de productos biológicos y las mejores estrategias de control para los patógenos emergentes. Esta pionera investigación desarrollada en Nicaragua, enfocada en la microbiota asociada al cultivo de la caña de azúcar, contribuye a la comprensión de la relación plantasuelo. Y los resultados aportan a la innovación agrícola, la mitigación de los efectos del cambio climático y la sostenibilidad ambiental.
