Salt-tolerant extracellular enzymes from the genus Gracilibacillus: A review

Le résumé fourni par la source

The genus Gracilibacillus includes over 20 species of halophilic bacteria which have been isolated from salterns, saline lakes or soils, plants, or animals and can grow in media containing 0.5% to 20% NaCl. The bacteria are Gram-positive motile thin rods or filaments that form terminal endospores. They release a variety of extracellular enzymes that are active in the presence of high salt concentrations but often also tolerate high temperatures, extreme pH, solvents, detergents, or metal ions. This review summarizes the characterization of five well-studied examples of these enzymes: an α-amylase/cyclodextrin glycosyl transferase from G. dipsosauri strain DD1: a xylanase from Gracilibacillus sp. strain TSCPVG, a protease from G. boraciitolerans strain LO15, an azo-dye reductase from Gracilibacillus sp. GTY, and an alginate lyase from Gracilibacillus strain A7. These studies illustrate how these proteins can be studied and suggest ways by which additional salt-tolerant extracellular enzymes from this group can be investigated.
