Tolerance of the Nanocellulose-Producing Bacterium Gluconacetobacter xylinus to Lignocellulose-Derived Acids and Aldehydes

Journal of Agricultural and Food Chemistry, 2014
Lignocellulosic biomass serves as a potential alternative feedstock for production of bacterial nanocellulose (BNC), a high-value-added product of bacteria such as Gluconacetobacter xylinus. The tolerance of G. xylinus to lignocellulose-derived inhibitors (formic acid, acetic acid, levulinic acid, furfural, and 5-hydroxymethylfurfural) was investigated.

Exploring Bacterial Cellulose and a Biosurfactant as Eco-Friendly Strategies for Addressing Pharmaceutical Contaminants

Molecules
Aquatic environments face contamination by pharmaceuticals, prompting concerns due to their toxicity even at low concentrations. To combat this, we developed an ecologically sustainable biosurfactant derived from a microorganism and integrated it into ...

Differentiation of Gluconacetobacter liquefaciens and Gluconacetobacter xylinus on the basis of DNA base composition, DNA relatedness, and oxidation products from glucose.

The Journal of General and Applied Microbiology, 1999
Gluconacetobacter liquefaciens and Gluconacetobacter xylinus share very similar phenotypic characteristics. They are differentiated by the production of a reddish-brown water-soluble pigment of the former and cellulose production of the latter. However, the loss of the two distinguishing features questions the separate standings of the two species. The

Production of bacterial cellulose membranes in a modified airlift bioreactor by Gluconacetobacter xylinus

, 2016
In this study, a novel bioreactor for producing bacterial cellulose (BC) is proposed. Traditional BC production uses static culture conditions and produces a gelatinous membrane.

Genetic Characteristics of Cellulose-Forming Acetic Acid Bacteria Identified Phenotypically asGluconacetobacter xylinus

Bioscience, Biotechnology, and Biochemistry, 2000
Gluconacetobacter xylinus (=Acetobacter xylinum) shows variety in acid formation from sugars and sugar-alcohols. Toyosaki et al. proposed new subspecies of G. xylinus (=Acetobacter xylinum) subsp. sucrofermentans in point of acid formation from sucrose and a homology index of 58.2% with the type strain of G. xylinus subsp.

Effects of Different Gluconacetobacter xylinus Strains on Yield and Properties of Bacterial Cellulose

Bioprocess, 2016
木葡糖酸醋杆菌是重要的细菌纤维素生产菌。该课题以40 g/L葡萄糖为碳源，研究了静态培养时5株菌种对细菌纤维素产量与性能的影响。采用扫描电镜、X射线衍射和万能材料测试机分别对细菌纤维素进行了形貌观察、结晶度表征以及力学性能测试。研究结果表明：细菌纤维素的产量排序依次为DHU-ZCY-1 (3.9 g/L) > DHU-ATCC-1 (2.6 g/L) > DHU-ZGD-1 (2.3 g/L) > DHU-YQ-1 (1.7 g/L) > ATCC23770 (0.6 g/L)；株型对细菌纤维素的含水率和结晶度基本无影响；不同菌株产的细菌纤维素湿膜的断裂拉伸强度大小依次如下：DHU-ZGD-1 (350 KPa) > DHU-ZCY-1 (150 KPa) > DHU-YQ-1 (68 KPa) >

Molecular Identification and Characterization of Some Gluconacetobacter Strains Isolated from Some Egyptian Fruits

, 2014
Three local isolates of biocellulose (BC)-producing Gluconacetobacter strains were isolated from rotten fruits out of 103 isolates. The representative isolates were selected from each of the 20 isolation sources (rotten fruits).

Comparison of bacterial cellulose production by Gluconacetobacter xylinus on bagasse acid and enzymatic hydrolysates

, 2017
To fulfill the comprehensive utilization of cellulose and hemicellulose components in bagasse for bacterial cellulose (BC) production, both bagasse acid and enzymatic hydrolysates were used for BC production by Gluconacetobacter xylinus.
