“…94 Similarly, membrane-based recovery and purification techniques have also been used in the downstream processing of other biosurfactants, such as the lipopeptide surfactin. 95,96 In this case, a two-step ceramic membrane ultrafiltration permitted a high recovery yield and purity, even in the presence of organic solvents. Therefore, the knowledge gathered from surfactin ultrafiltration processes could be fundamental for developing a highly efficient and low energy-demanding platform for MEL purification.…”

“…The market of bio-based surfactants (biosurfactants) has been increasing yearly, very likely due to the consumer demand for eco-friendly products and processes. In addition, environmental laws favor the biosurfactants market (Vicente et al 2021;Ahuja and Singh 2022).…”

“…As well as their synthetic analogs, biosurfactants reduce surface and interfacial tension as their concentration is increased in the medium until the maximum possible reduction (variable according to the type of surfactant or even the producing strain) is obtained when reaching the critical micelle concentration (CMC). Above CMC, these surfactants form self-aggregating structures that can be micellar, hexagonal, cubic, or lamellar (diameter 2-3 orders of magnitude larger than the isolated molecule) (Jauregi and Kourmentza 2000;Zanotto et al 2019;Vicente et al 2021).…”

“…It is also important to point out that a wide range of microorganisms can produce biosurfactants (Ron and Rosenberg 2001). In addition, the same strain can produce more than one type of biosurfactant; for example, Bacillus subtilis can produce surfactin, iturine, fengycin, and subtilisin (Vicente et al 2021). Natural surfactants can be classified into glycolipids, lipopeptides, lipoproteins, phospholipids, polymeric biosurfactants, and particulate surfactants.…”

The global production of cassava was estimated at ca. 303 million tons. Due to this high production, the cassava processing industry (cassava flour and starch) generates approximately ca. 0.65 kg of solid residue and ca. 25.3 l of wastewater per kg of fresh processed cassava root. The composition of the liquid effluent varies according to its origin; for example, the effluent from cassava flour production, when compared to the wastewater from the starch processing, presents a higher organic load (ca. 12 times) and total cyanide (ca. 29 times). It is worthy to highlight the toxicity of cassava residues regarding cyanide presence, which could generate disorders with acute or chronic symptoms in humans and animals. In this sense, the development of simple and low-cost eco-friendly methods for the proper treatment or reuse of cassava wastewater is a challenging, but promising path. Cassava wastewater is rich in macro-nutrients (proteins, starch, sugars) and micro-nutrients (iron, magnesium), enabling its use as a low-cost culture medium for biotechnological processes, such as the production of biosurfactants. These compounds are amphipathic molecules synthesized by living cells and can be widely used in industries as pharmaceutical agents, for microbial-enhanced oil recovery, among others. Amongst these biosurfactants, surfactin, rhamnolipids, and mannosileritritol lipids show remarkable properties such as antimicrobial, biodegradability, demulsifying and emulsifying capacity. However, the high production cost restricts the massive biosurfactant applications. Therefore, this study aims to present the state of the art and challenges in the production of biosurfactants using cassava wastewater as an alternative culture medium.

Corn steep water (CSW) is a complex agro-food stream that is used as a source of cost-competitive biosurfactants, since they are produced spontaneously in the steeping process of corn, avoiding production costs. Nevertheless, the extraction of biosurfactants from CSW using sustainable processes is still a challenge. Consequently, the use of calcium alginate membranes could present a novel and sustainable technology for recovering biosurfactants from aqueous streams. Therefore, the aim of this work is to evaluate calcium alginate-based biopolymers, without and with the presence of grape marc as an additive, as a key component of membranes for the recovery of biosurfactants in corn steep water. Biosurfactants are present in CSW, together with other inorganic solutes and biomolecules, such as organic acids, sugars, cations, anions as well as metals. Hence, the competition of these mentioned compounds for the active sites of the calcium alginate-based biopolymers was high. However, they showed a good adsorption capacity for biosurfactants, recovering around 55 ± 2% and 47 ± 1%, of biosurfactants from CSW using both calcium alginate-based biopolymers, with and without biodegraded grape marc. Regarding adsorption capacity, it was 54.8 ± 0.6 mg biosurfactant/g bioadsorbent for the biopolymer containing grape marc, and 46.8 ± 0.4 mg biosurfactant/g bioadsorbent for the calcium alginate-based biopolymer alone. Based on these results, it could be postulated that the formulation of green membranes, based on calcium alginate-based polymers, could be an interesting alternative for the recovery of biosurfactants from aqueous streams including CSW.
