“…More recently, the transformation of dairy industry waste and by-products into valueadded compounds through biotechnological processes has been considered. This approach proved that dairy waste can be a good source to produce many different materials such as bioplastics, biofuels, organic acids, and biosurfactants [11]. Industrial meat processing also significantly affects the environment contributing to climate change.…”

“…Landfill waste promotes the uncontrolled growth of microorganisms that cause bacterial contamination of groundwater and the production of toxic gases that contribute to air pollution. In addition, increased greenhouse gas emissions have devastating effects on climate by contributing to global warming [11]. On the other hand, the incineration of agri-food waste causes the release into the atmosphere of ashes, fumes, and dioxin with serious consequences for the health of living organisms and, more generally, of the environment.…”

Agri-food wastes generated by industrial food processing are valorized through the extraction of biomolecules to obtain value-added products useful for various industrial applications. In the present review, we describe the valuable by-products and bioactive molecules that can be obtained from agricultural wastes and propose extracellular vesicles (EVs) as innovative nutraceutical and therapeutic compounds that could be derived from agriculture residues. To support this idea, we described the general features and roles of EVs and focused on plant-derived extracellular vesicles (PDEVs) that are considered natural carriers of bioactive molecules and are involved in intercellular communication between diverse kingdoms of life. Consistently, PDEVs exert beneficial effects (anti-inflammatory, anti-tumor, and immune-modulatory) on mammalian cells. Although this research field is currently in its infancy, in the near future, the isolation of EVs and their use as nutraceutical tools could represent a new and innovative way to valorize waste from the agri-food industry in an ecofriendly way.

“…If not handled correctly, it can lead to pollution and the release of greenhouse gases. On the other hand, the idea of using dairy waste to make biosurfactants has recently gained a lot of attention ( Leong et al, 2021 ). The volume of dairy waste generated by activities involving the use of dairy products is substantial.…”

“…The primary constituents of dairy waste that are utilized in the production of biosurfactants are proteins and lipids derived from milk. Dairy effluent’s lactose and protein promote microbial development, which in turn leads to the generation of valuable byproducts ( Leong et al, 2021 ). Utilizing dairy waste for the production of biosurfactants is an ecologically conscientious and enduring approach to waste management.…”

The adverse effects of waste generation on the environment and public health have raised global concerns. The utilization of waste as a raw material to develop products with enhanced value has opened up novel prospects for promoting environmental sustainability. Biosurfactants obtained from agro-industrial waste are noteworthy due to their sustainability and environmental friendliness. Microorganisms have been employed to generate biosurfactants as secondary metabolites by making use of waste streams. The utilization of garbage as a substrate significantly reduces the expenses associated with the process. Furthermore, apart from reducing waste and offering alternatives to artificial surfactants, they are extensively employed in bioremediation, food processing, agriculture, and various other industrial pursuits. Bioremediation of heavy metals and other metallic pollutants mitigated through the use of bacteria that produce biosurfactants which has been the more recent research area with the aim of improving its quality and environmental safety. Moreover, the production of biosurfactants utilizing agricultural waste as a raw material aligns with the principles of waste minimization, environmental sustainability, and the circular economy. This review primarily focuses on the production process and various types of biosurfactants obtained from waste biomass and feedstocks. The subsequent discourse entails the production of biosurfactants derived from various waste streams, specifically agro-industrial waste.

“…The word "surfactant", was created from the phrase "surface active agent" (Rosen and Kunjappu, 2012). Biosurfactants are amphiphilic chemical compounds (they have a hydrophobic tail group and a hydrophilic head group (Leong et al, 2021)), produced by microorganisms, with many advantages over conventional surfactants (Sandeep and Rajasree, 2017). Some of these advantages include easy biodegradability, minimal toxicity and unaltered activity in extreme conditions of salinity and pH (Costa et al, 2018).…”

The worldwide occurrence of antibiotic resistance, has triggered the quest for viable alternatives, to the failing antibiotics in common usage. Biosurfactants have been studied for their potential in this regard. The aim of this study, was to characterise a biosurfactant, produced from Pseudomonas aeruginosa strain S16 (accession number OQ734845), shown to possess effective biocontrol activity, against Staphylococcus aureus SO183 at 0.060 g/L. Pseudomonas aeruginosa strain S16 was isolated from soil in a mixed farm, at Ajibode area, Ibadan, Oyo State, Nigeria, with the use of the pour plate method, identified through biochemical tests, and confirmed through molecular studies. Scanning electron microscopy revealed that the biosurfactant possessed a surface composed of, globular and spindle-shaped projections, while energy dispersive x-ray spectroscopy revealed that its elemental composition was mainly oxygen (3.00%), carbon (36.10%), nitrogen (43.00%), phosphorus (3.00%) and sodium (6.60%); the least abundant was manganese (0.48%). High performance liquid chromatography and mass spectrometry, revealed that the monosaccharides, were mainly rhamnose, glucose, xylose and mannose, while the phenol-sulfuric acid method measured their concentration as 0.0047 g/L. Fourier transform infrared spectroscopy, revealed the presence of carboxyl, alcohol, amine and halo functional groups, amongst others. The biosurfactant produced from Pseudomonas aeruginosa strain S16 was a positively charged, manganese-containing, polymeric biosurfactant made up of carbohydrates, lipid and peptide molecules. It was likely a positively-charged, manganese-containing glycolipopeptide/glycolipoprotein, polysaccharide-protein-fatty acid composite, or lipopolysaccharide-protein composite. The manganese probably conferred to it, the potential for antibacterial and diverse bioactivities. From available records, this is the first report of a manganese-containing biosurfactant.
