  • Zymomonas mobilis exopolysaccharide structure and role in high ethanol tolerance.
    Carbohydrate polymers, 2018
    Co-Authors: Mateusz Pallach, Roberta Marchetti, Flaviana Di Lorenzo, Antonio Fabozzi, Eric Giraud, Djamel Gully, Luigi Paduano, Antonio Molinaro, Gerardino D'errico, Alba Silipo
    Abstract:

    Bacterial cell surface exopolysaccharides (EPS) provide a protective barrier from the external milieu and participate in host-environment interactions. Zymomonas mobilis, an ethanologenic Gram negative bacterium, is used by the industry in bio-ethanol production process, due to its extraordinary resistance to a highly ethanolic environment. We found that Z. mobilis produces a mixture of two EPSs, an [α-(1→6)-D-Manp] mannose homopolymer and a galactose containing polysaccharide: [→2)-β-D-Galf-(1→3)-β-D-Galp-(1→]n. A physico-chemical study, conducted with diffusion-ordered spectroscopy (DOSY) and Dynamic Light Scattering (DLS), allowed to demonstrate that, differently from the majority of polysaccharides, ethanol is a good solvent for the galactose containing EPS, revealing that its chemical structure is specifically connected with the Zymomonas mobilis high ethanol tolerance.

Zymomonas mobilis, an ethanologenic Gram negative bacterium, is used by the industry in bio-ethanol production process, due to its extraordinary resistance to a highly ethanolic environment. We found that Z. mobilis produces a mixture of two EPSs, an [alpha - (1 -> 6)-D-Manp] mannose homopolymer and a galactose containing polysaccharide: [-> 2)-beta-D-Galf-(1 -> 3)-beta-D-Galp-(1 ->](n).

  • Zymomonas Mobilis—Science and Industrial Application
    Critical reviews in biotechnology, 1993
    Co-Authors: Horst W. Doelle, Lisa A. Kirk, Ross Crittenden, Hsien Toh, Monica B. Doelle
    Abstract:

    Zymomonas mobilis is undoubtedly one of the most unique bacterium within the microbial world. Known since 1912 under the names Termobacterium mobilis, Pseudomonas linderi, and Zymomonas mobilis, reviews on its uniqueness have been published in 1977 and 1988. The bacterium Zymomonas mobilis not only exhibits an extraordinarily uniqueness in its biochemistry, but also in its growth behavior, energy production, and response to culture conditions, as well as cultivation techniques used. This uniqueness caused great interest in the scientific, biotechnological, and industrial worlds. Its ability to couple and uncouple energy production in favor of product formation, to respond to physical and chemical environment manipulation, as well as its restricted product formation, makes it an ideal microorganism for microbial process development. This review explores the advances made since 1987, together with new developments in the pure scientific and applied commercial areas.
