The urealytically active microorganism Sporosarcina luteola induces the precipitation of metals which has attracted attention in biomineralization, bioremediation, and industrial waste recycling. Herein, we report a novel biosurfactant producing strain of Sporosarcina luteola ME44 isolated from Chinese oilfield. The structure, composition, and surface activity of the biosurfactants produced by Sporosarcina luteola ME44 were investigated by using a combination of the high‐performance liquid chromatography, time‐of‐flight mass spectrometry and surface tensiometer. The biosurfactant extracted by strain ME44 was identified as surfactin with five variants and the yield was 1,010 ± 60 mg⋅L−1. This is the first report on the structural composition and surface activity of biosurfactants isolated from the Sporosarcina luteola. It extended our knowledge about the role of the species Sporosarcina luteola in the ecosystem of extreme natural environments such as oil reservoir. In addition, Sporosarcina luteola ME44 showed bioprecipitation properties for metal ions Cd (II), Cu (II), Zn (II), and Ag (I), which indicated the application potential of Sporosarcina luteola in the field of bioremediation.This article is protected by copyright.

“…Finally, the organic system containing N235 and TBP was used to recover Ga(III) and Ge(IV). Saikia et al [12] studied the adsorption and precipitation of Ga, Ge, and Zn using chemical sulfur and biological sulfur (S 0 ). They found that bioderived adsorbents and biosulfides have good treatment effects.…”

“…It has been found that these metals are usually combined with Zn, Al, Pb, and Sn in bauxites, zinc concentrates, and fly ash used for coal combustion [11]. In primary resources, 90% of Ga comes from the aluminum oxide production process [12]. In addition, leaching residues from zinc hydrometallurgy and fly ash from coal combustion are also primary resources for Ga production.…”

Gallium (Ga), indium (In), and germanium (Ge) play an important role in the modern high-tech material field. Due to their low content and scattered distribution in the crust, and the increasing demand for these metals in recent years, their supply risks have sharply increased. Therefore, the recycling of these metals is of great significance. In this work, a systematic review was performed using the Web of Science, Scopus, MDPI, Elsevier, and Springer Link databases. The combined terms used for the search were Ga/In/Ge, extraction, separation, and recycling. After a careful evaluation of the titles, abstracts, and full texts, a total of 106 articles were included. This paper briefly describes the resource features of Ga, In, and Ge. After that, the chemical principles, technical parameters, and metal recovery in various extraction and separation methods from monometallic and polymetallic resources are systematically reviewed. Leaching followed by solvent extraction or ion exchange is the main process for Ga, In, and Ge recovery. Although many attempts have been made to separate multiple metals from leaching solutions, highly selective solvents and resins are still the research priority. This review can provide theoretical and technical guidance for the separation of Ga, In, and Ge from various resources.

“…In the case of gallium recovery, even the most recently proposed processes do not achieve a quantitative recovery. Thus, algae-based sorbents [ 8 ], biogenic elemental tellurium nanoparticles [ 9 ], synthetic zinc refinery residues [ 10 ] and H-clinoptilolite [ 11 ] have been successfully used as adsorbents. The reported removal efficiencies were, on average, 80% at low gallium concentrations (60% and 85% at 35 °C and 69 °C, respectively).…”

Using a Simple Magnetic Adsorbent for the Preconcentration and Determination of Ga(III) and In(III) by Electrothermal Atomic Absorption Spectrometry

et al. 2023

A solid-phase dispersive microextraction procedure has been developed using ferrite (Fe3O4), an inexpensive magnetic material, as an adsorbent for the separation and subsequent determination of Ga(III) and In(III). The ions were removed from an aqueous solution by adsorption on Fe3O4, which was next easily collected from the medium by the action of a magnet. The analytes were then desorbed using 50 µL of 2 M NaOH or 50 µL of a 4:1 mixture of 0.1 M EDTA and 2 M HNO3 for the determination of Ga(III) or In(III), respectively. The level of the elements in the desorption phase was measured by electrothermal atomic absorption spectrometry (ETAAS) by injecting 10 µL of this phase into the atomizer. The enrichment factor was 163, and detection limits of 0.02 and 0.01 µg L−1 were achieved for Ga(III) and In(III), respectively. The reliability of the procedure has been verified by means of standard reference materials and by means of standard additions. Results are given for waters, soils and samples obtained from various electronic devices. It is of note that the procedure could be the basis for a useful way of recovering these valuable elements from different matrices for reuse.
