BACKGROUNDLevulinic acid (LA) is a multifunctional compound that is relevant to the economy of bio‐based chemical products. Citrus sinensis, the Valencia variety, is one of the world's most consumed citrus fruit varieties but suffers significant losses due to blue mold infestation. This research evaluated the inhibitory action of unpurified levulinic acid obtained from watermelon residues against the fungus Penicillium italicum, proposing a new use as a fungal inhibitor.RESULTSLA was evaluated in in vitro tests and inhibited the mycelial growth of the fungus. In in vivo experiments with oranges, fungal proliferation in fruits was investigated by applying a crude mixture containing LA (43 mM) and formic acid (FA, 28 mM), comparing with FA alone and negative control (without inhibitory agent). The weight loss and disease incidence results decreased when LA was used as an inhibitory agent, with no negative impacts on fruit quality being observed. Its inhibitory effect was confirmed by determining the activities of the antioxidant enzymes catalase (CAT), ascorbate peroxidase (APX), superoxide dismutase (SOD), and peroxidase (POD), where there was no increase in activities due to inhibition of the fungus before its proliferation in the fruits.CONCLUSIONThis study provides relevant data on the new use of raw LA as an antifungal agent, an effect still unexplored for this compound in recent literature, offering a practical and innovative solution to combat blue mold.This article is protected by copyright.

With the expansion of the green products market and the worldwide policies and strategies directed toward a green revolution and ecological transition, the demand for innovative approaches is always on the rise. Among the sustainable agricultural approaches, microbial-based products are emerging over time as effective and feasible alternatives to agrochemicals. However, the production, formulation, and commercialization of some products can be challenging. Among the main challenges are the industrial production processes that ensure the quality of the product and its cost on the market. In the context of a circular economy, solid-state fermentation (SSF) might represent a smart approach to obtaining valuable products from waste and by-products. SSF enables the growth of various microorganisms on solid surfaces in the absence or near absence of free-flowing water. It is a valuable and practical method and is used in the food, pharmaceutical, energy, and chemical industries. Nevertheless, the application of this technology in the production of formulations useful in agriculture is still limited. This review summarizes the literature dealing with SSF agricultural applications and the future perspective of its use in sustainable agriculture. The survey showed good potential for SSF to produce biostimulants and biopesticides useful in agriculture.

“…Despite a few studies using yeasts as bioherbicides, there is some evidence of their potential to inhibit weed growth. Yeasts carrying enzymes such as lipases, cellulases, xylanases, pectinases, proteases, and peroxidases are capable of degrading the polysaccharides of weeds’ cell walls [ 140 , 141 ]. Species such as Papiliotrema laurentii , Meyerozyma caribbica , and Rhodotorula mucilaginosa isolated from insects and an Antarctic lagoon, for example, are capable of secreting these enzymes [ 140 , 142 ].…”

“…In this case, through the metabolic routes of glycosides, yeasts can be used to produce these compounds from complex substrates containing polysaccharides [ 62 , 155 , 156 ]. Therefore, polysaccharide-rich waste hydrolysates (such as sugarcane bagasse, fruit peels, and algal biomass extract) can be used as feedstocks for the production of growth promoters, biocontrol agents, and bioherbicides with circular economy consistency [ 16 , 141 , 157 ].…”

The literature is full of studies reporting environmental and health issues related to using traditional pesticides in food production and storage. Fortunately, alternatives have arisen in the last few decades, showing that organic agriculture is possible and economically feasible. And in this scenario, fungi may be helpful. In the natural environment, when associated with plants, these microorganisms offer plant-growth-promoting molecules, facilitate plant nutrient uptake, and antagonize phytopathogens. It is true that fungi can also be phytopathogenic, but even they can benefit agriculture in some way—since pathogenicity is species-specific, these fungi are shown to be useful against weeds (as bioherbicides). Finally, plant-associated yeasts and molds are natural biofactories, and the metabolites they produce while dwelling in leaves, flowers, roots, or the rhizosphere have the potential to be employed in different industrial activities. By addressing all these subjects, this manuscript comprehensively reviews the biotechnological uses of plant-associated fungi and, in addition, aims to sensitize academics, researchers, and investors to new alternatives for healthier and more environmentally friendly production processes.
