Product value-addedThe recovery of alginate-like extracellular polymer (ALE) from municipal sludge is a highly anticipated approach for addressing resource and climate crises, achieving sustainable development, and transforming water-resource factories. This review begins with the recovery of ALE from ...

but also by other polymers such as proteins, humic substances, and lipids9. During ALE extraction, some intracellular polysaccharides and proteins can be released by cell lysis10; this combination of ALE and intracellular polymers is referred to as alginate-like polymers (ALP...

the cross-section area of samples was assessed using BEL View image analysis software (6.2.2.1). Assuming a sphere-like pore shape, the equivalent diameter was reported as the pore size. The distribution of pore sizes in the hydrogel samples was supposed to be Gaussian and the following equati...
The mannuronan C-5 epimerases catalyze epimerization of β-d-mannuronic acid to α-l-guluronic acid in alginate polymers. The seven extracellular Azotobacter vinelandii epimerases (AvAlgE1-7) are calcium-dependent, and calcium is essential for the structural integrity of their carbohydrate binding...
Previously the collagen/alginate combination has been used to create a structurally switchable 3D extracellular matrix26. As a polymer base for cell culture, alginate has many favora- ble attributes, including biocompatibility, lack of immunoresponse, precise mechanical control, no mammalian receptors, ...
Immunotherapies have been gaining attention for the prevention of cancer recurrence and metastasis. Cancer immunotherapy can induce memory cells to target cancer-specific antigens and, thus, selectively kill cancer cells. However, there are difficulties
Although, at first, the EPS solubilization from the biomass is necessary, it is not certain that polymers originate solely from the extracellular polymeric matrix. This is true for likely all studies in which ALE was recovered with harsh extraction methods. Hence, the term “extracellular polymeric...
Although natural polymers have good biological properties, their mechanical properties are poor, and they cannot withstand the stress transmitted by bones when used as scaffolds alone [201]. As a result, they can be combined with other materials to improve the mechanical properties while also exertin...
