20.500.12556/RUL-135212 Acetan and acetan-like polysaccharides genetics, biosynthesis, structure, and viscoelasticity Bacteria produce a variety of multifunctional polysaccharides, including structural, intracellular, and extracellular polysaccharides. They are attractive for the industrial sector due to their natural origin, sustainability, biodegradability, low toxicity, stability, unique viscoelastic properties, stable cost, and supply. When incorporated into different matrices, they may control emulsification, stabilization, crystallization, water release, and encapsulation. Acetan is an important extracellular water-soluble polysaccharide produced mainly by bacterial species of the genera Komagataeibacter and Acetobacter. Since its original description in Komagataeibacter xylinus, acetan-like polysaccharides have also been described in other species of acetic acid bacteria. Our knowledge on chemical composition of different acetan-like polysaccharides, their viscoelasticity, and the genetic basis for their production has expanded during the last years. Here, we review data on acetan biosynthesis, its molecular structure, genetic organization, and mechanical properties. In addition, we have performed an extended bioinformatic analysis on acetan-like polysaccharide genetic clusters in the genomes of Komagataeibacter and Acetobacter species. The analysis revealed for the first time a second acetan-like polysaccharide genetic cluster, that is widespread in both genera. All species of the Komagataeibacter possess at least one acetan genetic cluster, while it is present in only one third of the Acetobacter species surveyed. extracellular polysaccharide acetan acetan genetic cluster acetan synthesis acetan viscoelasticity applications of acetan Komagataeibacter Acetobacter acetan-like polysaccharide acetan-like polysaccharide genetic cluster acetan structure true false true Angleški jezik Ni določen Članek v reviji 2022-03-01 09:30:51 2022-03-01 09:30:57 2022-09-14 04:12:12 0000-00-00 00:00:00 2021 0 0 16 str. iss. 5, art. 815 Vol. 13 Mar. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 577.1 2073-4360 10.3390/polym13050815 54160899 RAZ_Trcek_Janja_2021.pdf RAZ_Trcek_Janja_2021.pdf 1 52334B9EB9E1A3B9319B1F4EEA59D769 63b9e1eb0807ab327fe47d10209e2542af4c1d10e2fd2842ff99a0b4a8748ef2 2510ab4c-993a-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154132 https://www.mdpi.com/2073-4360/13/5/815 0 f7756271-9939-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154131 Biotehniška fakulteta 0 0 0
