“…Cell immobilization using an alginate matrix is very versatile and presents different applications, allowing the use of live or inactivated cells in bioreactors (Kureel et al 2017), enabling innovative applications in different areas. Bioreactors operated using microbial cells immobilized on Ca 2+ alginate beads has been extensively described in the literature in fermentation processes, e.g., for production of acids (Yoo et al 1996), carotenoids (Garbayo et al 2003), sweeteners (Kawaguti and Sato 2011), fermented beverages (García-Martínez et al 2015) and ethanol (Bangrak et al 2011).…”

Immobilized microbial cells have been used extensively in various industrial processes. However, immobilized cells have not been used widely for mining industrial applications. Cell immobilization consists of a technique by which microorganisms are confined through physical or chemical interactions in a matrix, or fixed to the surface of the immobilizing agent. In recent years, entrapment of cells within spheres of Ca 2+ alginate has become the most widely used technique for immobilizing living cells. This review examines many of the scientific and technical aspects involved in using Ca 2+ alginate immobilized microbial cells in mining activities, with a particular focus on the biohydrometallurgical industrial applications and processes of soil bioremediation in heavy metal contaminated mining areas, environmental recovery of atmospheric emissions containing H2S and treatment of acid mine drainage.Palabras clave: alginato de Ca 2+ , industria minera, inmovilización celular, recuperación ambiental RESUMEN Las células microbianas inmovilizadas se han utilizado ampliamente en diversos procesos industriales. Sin embargo, no se han usado de manera tan extensa en las aplicaciones para la industria minera. La inmovilización celular consiste en una técnica mediante la cual los microorganismos se confinan a través de interacciones físicas o químicas en una matriz, o se fijan a la superficie del agente inmovilizador. En los últimos años, el atrapamiento de las células dentro de esferas de alginato de Ca 2+ se ha convertido en la técnica más utilizada para inmovilizar las células vivas. Esta revisión examina muchos de los aspectos científicos y técnicos que abarca el uso de células microbianas inmovilizadas con alginato de Ca 2+ en aplicaciones en las actividades mineras, con un enfoque particular en las industriales biohidrometalúrgicas y en los procesos de biorremediación de suelos en áreas mineras contaminadas con metales pesados, recuperación ambiental de emisiones atmosféricas que contienen H2S y tratamiento del drenaje ácido de minas.

“…Glucosyltransferase from Erwinia sp. was used for immobilization in Ca-alginate beads in the form of crude extract or whole cells lysed by ultrasonication (Kawaguti and Sato 2011). Lysed cells showed higher stability than the crude enzyme extract, and reached 53%-59% conversion of sucrose to isomaltulose.…”

Isomaltulose is a natural isomer of sucrose. It is widely used as a functional sweetener with promising properties, including slower digestion, lower glycemic index, prolonged energy release, lower insulin reaction, and less cariogenicity. It has been approved as a safe sucrose substitute by the Food and Drug Administration of the US; Ministry of Health, Labor and Welfare of Japan; and the Commission of the European Communities. This article presents a review of recent studies on the properties, physiological effects, and food application of isomaltulose. In addition, the biochemical properties of sucrose isomerases producing isomaltulose are compared; the heterologous expression, fermentation optimization, structural determination, and catalysis mechanism of sucrose isomerase are reviewed; and the biotechnological production of isomaltulose from sucrose is summarized.
