“…Alg polymer includes a pair of monomers as a duplicating unit, which is (1-4)-β- d -mannuronic acid (M) and α- l -guluronic acid (G), as can be observed in Figure 1 [ 2 ]. However, α- l -guluronic acid stimulates the gel creation, the (1-4)-β- d -mannuronic acid, and a mixture of (L-4)-β- d -mannuronic acid and α- l -guluronic acid offers flexibility in the polymer matrix [ 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 ].…”

Three-dimensional (3D) bioprinting is an appealing and revolutionary manufacturing approach for the accurate placement of biologics, such as living cells and extracellular matrix (ECM) components, in the form of a 3D hierarchical structure to fabricate synthetic multicellular tissues. Many synthetic and natural polymers are applied as cell printing bioinks. One of them, alginate (Alg), is an inexpensive biomaterial that is among the most examined hydrogel materials intended for vascular, cartilage, and bone tissue printing. It has also been studied pertaining to the liver, kidney, and skin, due to its excellent cell response and flexible gelation preparation through divalent ions including calcium. Nevertheless, Alg hydrogels possess certain negative aspects, including weak mechanical characteristics, poor printability, poor structural stability, and poor cell attachment, which may restrict its usage along with the 3D printing approach to prepare artificial tissue. In this review paper, we prepare the accessible materials to be able to encourage and boost new Alg-based bioink formulations with superior characteristics for upcoming purposes in drug delivery systems. Moreover, the major outcomes are discussed, and the outstanding concerns regarding this area and the scope for upcoming examination are outlined.

“…Alginateentrapped bacterial cells were visually evaluated on the bead surface as seen in (Fig. 1C, D), since bacterial cells were restricted into the inner surface of the alginate beads via the entrapment process (Moreno Rivas et al, 2019). In this way, the immobilization efficiency (Yi) and bacterial cell retention (Cr) by the carrier was measured up to h. As shown from (Fig.…”

Bacterial cellulose (BC) has profound applications in different sectors of biotechnology due to its unique properties preferring it about plant cellulose. Although this polymer is extremely important in various applications, many problems still hinder the sustainable production in terms of increasing productivity and low-cost production. In order to overcome these problems, this study will focuses on the continuous production of cellulose using immobilized Glucanobacter xylinum cells onto Sugar Cane Bagasse (SCB) and Ca-alginate beads. Comparatively, adsorption of Glucanobacter xylinum cells to the cavum of stalk cells of SCB could be efficiently stable while, entrapment of cells onto Ca-alginate has drawback observed by the rapid disruption and instability of the beads in the Potato Peel Waste (PPW) culture medium. Our findings demonstrate that a combination between alternative low-cost medium with continuous production mode by immobilization onto inexpensive natural polymer can promote a sustainable bioprocess and reduction the production cost.

Encapsulation of Saccharomyces pastorianus Residual Biomass in Calcium Alginate Matrix with Insights in Ethacridine Lactate Biosorption

Pharmaceuticals are recognized as emerging water microcontaminants that have been reported in several aquatic environments worldwide; therefore, the elimination of these pollutants is a global challenge. This study aimed to develop a biosorbent based on Saccharomyces pastorianus residual biomass encapsulated in a calcium alginate matrix and to evaluate its biosorption performance to remove Ethacridine Lactate (EL) from aqueous solutions. Firstly, the synthesis and characterization of biosorbent has been carried out. Then, the impact of main parameters on biosorption process were investigated by batch experiments. Finally, the kinetics behavior and equilibrium isotherms were evaluated. The resulted beads have an irregular and elongated shape with about 1.89 mm ± 0.13 mm in size with a homogeneous structure. The best removal efficiency for EL of over 85% was obtained at acidic pH 2 and 25 °C for 50 mg/L initial concentration and 2 g/L biosorbent dose. The pseudo-second-order and intraparticle diffusion kinetics describe the biosorption process. The maximum calculated biosorption capacity was 21.39 mg/g similar to that recorded experimentally. The equilibrium biosorption data were a good fit for Freundlich and Dubinin–Radushkevich isotherms. Our findings reveal that the low cost and eco-friendly obtained biosorbent can be easily synthesized and suitable to remove Ethacridine Lactate from water matrices.
