“…An alternative is to make from these bacterial immunogenic compounds microbial-derived products for the phytosanitary market provided that they can be produced and formulated in cost-effective industrial processes. This is feasible for some metabolites with high production rate in bioreactors, such as Bacillus lipopeptides (Zanotto et al, 2019;Brück et al, 2020), but the dose and structure dependent activity should guide a rational selection of the strain, optimization of culture conditions and extensive testing in field experiments in comparison with chemical products.…”

The molecular basis of plant immunity triggered by microbial pathogens is being well-characterized as a complex sequential process leading to the activation of defense responses at the infection site, but which may also be systemically expressed in all organs, a phenomenon also known as systemic acquired resistance (SAR). Some plant-associated and beneficial bacteria are also able to stimulate their host to mount defenses against pathogen ingress via the phenotypically similar, induced systemic resistance phenomenon. Induced systemic resistance resembles SAR considering its mechanistic principle as it successively involves recognition at the plant cell surface, stimulation of early cellular immune-related events, systemic signaling via a fine-tuned hormonal cross-talk and activation of defense mechanisms. It thus represents an indirect but efficient mechanism by which beneficial bacteria with biocontrol potential improve the capacity of plants to restrict pathogen invasion. However, according to our current vision, induced systemic resistance is specific considering some molecular aspects underpinning these different steps. Here we overview the chemical diversity of compounds that have been identified as induced systemic resistance elicitors and thereby illustrating the diversity of plants species that are responsive as well as the range of pathogens that can be controlled via this phenomenon. We also point out the need for further investigations allowing better understanding how these elicitors are sensed by the host and the diversity and nature of the stimulated defense mechanisms.

“…Based on their chemical structure microbial biosurfactants are classified as glycolipids, lipopeptides, phospholipids, polymeric surfactants, and particulate surfactants [ 29 ]. Rhamnolipids, sophorolipids, and surfactin are the most widely studied microbial biosurfactants.…”

“…Rhamnolipids, sophorolipids, and surfactin are the most widely studied microbial biosurfactants. Their antimicrobial (antibacterial and antifungal), pharmaceutical and medical applications such as anticancer, anti-inflammatory and immunomodulators, antihypertensive activities are well reported in the literature [ 30 , 6 , 29 , 31 ]. More importantly, they have also been active against various viruses.…”

“…37,38 Different CMC values are obtained depending on the chemical structure of the biosurfactant and this value is influenced by the self-aggregation of molecules (micellar, hexagonal, cubic, or lamellar), which is governed by intermolecular electrostatic interactions, polarity, ionic strength and temperature of the solvent (Figure 3). 39 CMC values measure the efficiency of a biosurfactant, whereas surface and interfacial tension values determine its effectiveness. 40 The molecular weight of a biosurfactant should also be considered when studying its properties.…”

There has been considerable interest in the use of biosurfactants due to the diversity of structures and the possibility of production from a variety of substrates. The potential for industrial applications has been growing, as these natural compounds are tolerant to common processing methods and can compete with synthetic surfactants with regards to the capacity to reduce surface and interfacial tensions as well as stabilise emulsions while offering the advantages of biodegradability and low toxicity. Among biosurfactant-producing microorganisms, some yeasts present no risks of toxicity or pathogenicity, making them ideal for use in food formulations. Indeed, the use of these biomolecules in foods has attracted industrial interest due to their properties as emulsifiers and stabilizers of emulsions. Studies have also demonstrated other valuable properties, such as antioxidant and antimicrobial activity, enabling the aggregation of greater value to products and the avoidance of contamination both during and after processing. All these characteristics allow biosurfactants to be used as additives and versatile ingredients for the processing of foods. The present review discusses the potential application of biosurfactants as emulsifying agents in food formulations, such as salad dressing, bread, cakes, cookies, and ice cream. The antioxidant, antimicrobial and anti-adhesive properties of these biomolecules are also discussed, demonstrating the need for further studies to make the use of the natural compounds viable in this expanding sector.
