“…As a result, the current trend is to use crop‐derived starch to produce biocompatible and food‐grade surfactants (Bhadani et al, 2020). In addition to starch, alternative resources such as lignocellulosic materials, food waste, wood, and nonwood residues (Calicioglu et al, 2021; Maia et al, 2020; Parchami et al, 2021) are becoming the preferable choices of research according to life cycle assessments (LCAs) and techno‐economic analyses (Athaley et al, 2019; Kannah et al, 2021; F. Liu et al, 2021).…”

This work reviews the use of carbohydrates and their derivatives as renewable raw materials in the production of surfactants. Methods to attain state‐of‐the‐art carbohydrate‐derived surfactants are described. This includes surfactants widely used nowadays and others that have not yet transcended beyond the academic field. Given the abundance of hydroxyl groups in carbohydrates and the considerable quantity of different surfactant structures that can be generated during their synthesis, selectively obtaining a target product represents a challenge. Therefore, this work focuses on the platform chemicals available to synthesize biobased surfactants. The first part of the review comprises a brief introduction of simple and complex carbohydrates to better understand their chemistry. Then, a description of the processes to obtain biobased building blocks derived from carbohydrates according to the National Renewable Energy Laboratory (NREL, USA), and their usefulness in synthesizing surfactants is presented. This provides an organized inventory of the knowledge around the synthesis–production of surfactants from carbohydrate derivatives, emphasizing raw materials that could be inserted into the circular bioeconomy concept. Finally, the current industry trends and the potential role of biobased surfactants around new dioxane regulations are discussed.

“…These bioproducts can even be sold helping to pay the costs in the entire treatment system. Microalgae can be used as biofuels (biomethane, biodiesel and bioethanol) (Xiao, et al, 2019;Maia, et al, 2020) and even as biopolymers for the development of bioplastics, which can move the regional socioeconomic scenario (Marques, et al, 2020;Duarte, et al, 2021).…”

“…Microalgae are aquatic microorganisms, photosynthesizer, which transform light, carbon dioxide present in the atmosphere and the nutrients present in the water into biomass rich in different molecules, such as proteins, carbohydrates, lipids, vitamins and antioxidants (Marques, et al, 2021). These biomass components are used for the production of bioproducts such as: biodiesel (Dogaris, et al, 2020), bioethanol (Maia, et al, 2020), bioplastics (Chong, et al, 2022) biomethane (Xiao, et al, 2019), biohydrogen (Batista, et al, 2015), bioelectricity (Maity, et al, 2014).…”

O cultivo de microalgas em resíduos líquidos surge como uma possibilidade biotecnológica devido à sustentabilidade do processo, uma vez que poluentes presentes em resíduos como nitrogênio (N) e fósforo (P) são utilizados por esses microrganismos como nutrientes para seu crescimento e produção de biomassa com valor adicionado. O objetivo deste trabalho foi desenvolver um protótipo de fotobiorreatores para remoção de nutrientes: nitrogênio e fósforo através do cultivo da microalga Chlorella vulgaris em lixiviado de aterro sanitário diluído em efluente doméstico. O cultivo teve duração de 28 dias onde foi avaliada a remoção de nutrientes nitrogênio e fósforo, bem como o crescimento de microalgas. Os melhores resultados de crescimento de microalgas foram obtidos em fotobiorreatores contendo 100% de efluente doméstico e 15% de chorume com concentração de clorofila de 2.277,08±247,21 µg.L-1 e 223,12±17,44 µg.L-1, respectivamente, no 21º dia de cultivo. Com relação à remoção de nutrientes de nitrogênio e fósforo, foi possível observar que a espécie utilizada neste estudo apresenta boa eficiência, cerca de 72,36% para nitrogênio e 44,32% para fósforo ao final do cultivo.

“…Storage polysaccharides have different structures depending on phyla, e.g., cyanobacteria (including Spirulina and Arthrospira species) synthesize glycogen in the cytosol and chlorophyceae like the microalga Chlorella fusca accumulate amylopectin-like polysaccharides (starch) in the plastid [7][8][9][10], under specific conditions [11,12]. Such storage carbohydrates can be used as feedstock for bioethanol production [13].…”

Static Magnetic Fields Effects on Polysaccharides Production by Different Microalgae Strains

Microalgae are able to produce many valuable biomolecules, such as polysaccharides, that presents a large diversity of biochemical structures and functions as antioxidant, antifungal, anticancer, among others. Static magnetic fields (SMF) influence the metabolism of microorganisms and has been shown as an alternative to increase microalgae biomass, yield and compounds production. Especially, some studies have highlighted that SMF application could enhance carbohydrate content. This study aimed to evaluate different conditions of SMF on Spirulina and Chlorella in indoor and outdoor conditions, in order to confirm the influence of SMF on polysaccharides production, evaluating which polysaccharidic fraction could be enhanced by SMF and highlighting a possible modification in EPS composition. Starch from Chlorella and exopolysaccharides (EPS) from Spirulina were quantified and characterized. SMF increased the starch content in Chorella fusca biomass. EPS productions from A. platensis and Spirulina sp. were not significantly increased, and global composition appeared similar to the controls (constituted basically of 80%–86% neutral sugars and 13%–19% uronic acids). However, the monosaccharide composition analysis revealed a significant modification of composition, i.e., the amount of fucose, arabinose, rhamnose, galactose and glucuronic acid was increased, while the glucose content was decreased. SMF application led to significant modification of polysaccharides production and this study demonstrate that combining the outdoor conditions with SMF, the starch content and EPS composition was positively affected.
