To guarantee the supply of critical elements in the future, the development of new technologies is essential. Siderophores have high potential in the recovery and recycling of valuable metals due to their metal-chelating properties. Using the Chrome azurol S assay, 75 bacterial strains were screened to obtain a high-yield siderophore with the ability to complex valuable critical metal ions. The siderophore production of the four selected strains Nocardioides simplex 3E, Pseudomonas chlororaphis DSM 50083, Variovorax paradoxus EPS, and Rhodococcus erythropolis B7g was optimized, resulting in significantly increased siderophore production of N. simplex and R. erythropolis. Produced siderophore amounts and velocities were highly dependent on the carbon source. The genomes of N. simplex and P. chlororaphis were sequenced. Bioinformatical analyses revealed the occurrence of an achromobactin and a pyoverdine gene cluster in P. chlororaphis, a heterobactin and a requichelin gene cluster in R. erythropolis, and a desferrioxamine gene cluster in N. simplex. Finally, the results of the previous metal-binding screening were validated by a proof-of-concept development for the recovery of metal ions from aqueous solutions utilizing C18 columns functionalized with siderophores. We demonstrated the recovery of the critical metal ions V(III), Ga(III), and In(III) from mixed metal solutions with immobilized siderophores of N. simplex and R. erythropolis.

“…Industrial activities are considered the main sources of environmental pollution with heavy metal ions. Thus, different industrial sectors, such as metallurgy, mining, electroplating, coating, fertilizers manufacturing, etc., [2][3][4] generate an important amount of effluents that contain huge amounts of heavy metals ions, and whose discharge without proper treatment is a threat to the quality of the environment. Therefore, it is necessary to find suitable methods that are environmentally friendly and remove heavy metal ions more efficiently and cheaply [5].…”

In recent years, studies on the more efficient use of natural materials in adsorption processes have increased significantly. Thus, obtaining new adsorbents from marine algae biomass with higher adsorptive performance will ensure a better use of these renewable resources. In this study, the adsorption of Cu(II) ions from aqueous solution was done using three types of adsorbent materials obtained from marine red algae biomass (Callithamnion corymbosum sp.), namely: alginate (Alg), algae waste biomass resulted after alginate extraction (AWB) and iron nanoparticles functionalized with alginate (Fe-NPs-Alg), compared to raw marine red algae biomass (RAB). FTIR spectra and SEM images recorded for each type of adsorbent indicate a porous structure and the presence of various superficial functional groups who may be involved in the retention of Cu(II) ions. The biosorption experiments were performed in a batch system, at different initial Cu(II) ion concentrations and contact times, maintaining a constant initial solution pH (4.4), adsorbent dose (2.0 g/L), and temperature (25 ± 1 °C). The obtained results indicate that the retention of Cu(II) ions requires a maximum of 60 min to reach equilibrium, and the maximum adsorption capacity increases in order: RAB (47.62 mg/g) < Fe-NPs-Alg (52.63 mg/g) < AWB (83.33 mg/g) < Alg (166.66 mg/g). The quantitative removal of Cu(II) ions from aqueous effluents can be done in two successive adsorption stages, using AWB (in the first stage) and Fe-NPs-Alg (in the second stage), when the treated solution has a Cu(II) ions concentration below the maximum permissible limit. The quantitative recovery of retained Cu(II) ions (over 97%) can be done by treating these exhausted adsorbent materials with 0.1 N HNO3 solution. Therefore, the extraction of alginate from marine red algae biomass could be a viable solution to obtain efficient adsorbent materials for Cu(II) ions removal from aqueous media, and allow for a better valorisation of marine red algae biomass.

“…Natural products, especially carbohydrates, represent important biomass sources because they are both plentiful and inexpensive 20,21 . For many years, researchers have studied the possibility of synthesizing biomaterials based on starch, cellulose, and chitin (as well as their derivatives) through chemical and physical methods with potential applications in the pharmaceutical, chemical, cosmetics, and plastics industries 22 .…”

Self‐healing carbohydrate polymers were synthesized by Diels‐Alder reaction. Intermediate products and the carbohydrate matrices were characterized by Fourier transform infrared spectroscopy (FT‐IR) and 1H NMR, while the thermally reversible properties were assessed by FT‐IR and differential scanning calorimetry. The mechanical properties, water absorption, and enzymatic degradation of starch/PVA/modified carbohydrate films were examined, as well as the relationship of the properties to the DA and rDA reactions. These results showed that DA bonds were introduced into the carbohydrate polymers successfully and endow the material with self‐healing thermal recyclability. The mixed films exhibited alternating strong and weak mechanical properties upon cycling through the DA and rDA reactions. Water absorption was limited and the films demonstrated good water resistance. The status of the DA bonds was found not to affect the enzymatic degradation rates of the various carbohydrate films.
