Strain M438, deposited as CGMCC3917 and isolated from inoculums of bacterial cellulose (BC) producing strain screened in homemade vinegar and then induced by high hydrostatic pressure treatment (HHP), has strong ability to produce BC more than three times as that of its initial strain. It is the highest yield BC-producing strain ever reported. In this paper, M438 was identidied as Gluconacetobacter hansenii subsp. nov. on the basis of the results obtained by examining it phylogenetically… 
Characterizations of Bacterial Cellulose Producing Strain Gluconoacetobacter hansenii CGMCC3917
Gluconoacetobacter hansenii CGMCC3917 (M438), isolated from inoculums of strain J2 treated by high hydrostatic pressure, has strong ability of producing cellulose as more than three times as that of
The effect of ultraviolet modification of Acetobacter xylinum (CGMCC No. 7431) and the use of coconut milk on the yield and quality of bacterial cellulose
This paper reports on the treatment of Acetobacter xylinum (CGMCC No. 7431) by ultraviolet (UV) to investigate the role of mutagenesis on the production of cellulose. When Acetobacter xylinum was
Characterization of Bacterial Cellulose by Gluconacetobacter hansenii CGMCC 3917.
The results suggest that the bacterial cellulose produced from HHP-mutant strain has an effective characterization, which can be used for a wide range of applications in food industry.
Komagataeibacter hansenii CGMCC 3917 alleviates alcohol-induced liver injury by regulating fatty acid metabolism and intestinal microbiota diversity in mice.
Findings suggest that K. hansenii CGMCC 3917 cells alleviate alcohol-induced liver damage via regulating fatty acid metabolism and intestinal microbiota diversity in mice, and could regulate gut microbiome by significantly decreasing the abundance of Actinobacteria, Proteobacteria and Firmicutes, and dramatically increasing the availability of Bacteroidetes in alcohol-treated mice.
Antioxidant properties of Komagataeibacter hansenii CGMCC 3917 and its ameliorative effects on alcohol-induced liver injury in mice
In vivo and in vitro study suggested that K. hansenii CGMCC 3917 exhibited strong scavenging abilities against DPPH, ABTS, OH free radicals and reducing power, suggesting significant anti-oxidant ability.
Enhancement of the fermentation process and properties of bacterial cellulose: a review
AbstractCellulose produced by bacteria (BC) has attracted increasing interest in view of its superior properties with respect to nanofibrillar structure, high purity and biocompatibility. Despite the
Recent advances in bacterial cellulose
This review mainly summarizes the recent developments of the functional products fabricated with BC and highlights the literatures mainly in last 5 years to provide the state-of-the-art opinions in areas wherever are focused on for BC researching.

Nitrogen-fixing and cellulose-producing Gluconacetobacter kombuchae sp. nov., isolated from Kombucha tea.
Strain RG3T produced cellulose in both nitrogen-free broth and enriched medium and exhibited low values of 5.2-27.2 % DNA-DNA relatedness to the type strains of related gluconacetobacters, which placed it within a separate taxon.
Description of Gluconacetobacter swingsii sp. nov. and Gluconacetobacter rhaeticus sp. nov., isolated from Italian apple fruit.
Two Gram-negative, rod-shaped, non-spore-forming bacteria isolated from apple fruit juice in the region of the Italian Alps were shown to belong to the alpha-subclass of the Proteobacteria, and, in particular, to the genus Gluconacetobacter, in the Glu Conacetobacteria xylinus branch.
Production of bacterial cellulose byGluconacetobacter hansenii PJK isolated from rotten apple
A cellulose-producing strain isolated from rotten apples was identified asGluconace-tobacter hansenii based on its physiological properties and the 16S rDNA complete sequencing method, and
Mutagenesis induced by high hydrostatic pressure treatment: a useful method to improve the bacterial cellulose yield of a Gluconoacetobacter xylinus strain
HHP treatment can serve as an effective method to cause mutagenesis in BC-producing bacteria and strains with significantly higher BC yield than parental strain can be screened from the HHP-induced mutants.
Reclassification of Gluconacetobacter hansenii strains and proposals of Gluconacetobacter saccharivorans sp. nov. and Gluconacetobacter nataicola sp. nov.
Ten strains previously assigned to Acetobacter hansenii, AcetOBacter pasteurianus LMG 1584 and eight reference strains of the genus Gluconacetobacter were reclassified by 16S rRNA gene sequencing, DNA-DNA similarity, DNA base composition and phenotypic characteristics.
Large-Scale Transposon Mutagenesis of Photobacterium profundum SS9 Reveals New Genetic Loci Important for Growth at Low Temperature and High Pressure
These analyses of genes conditionally required for low-temperature or high-pressure growth in a deep-sea microorganism were the first global analyses of signal transduction mechanisms in adaptation to either physical parameter.
Intrageneric structure of the genus Gluconobacter analyzed by the 16S rRNA gene and 16S-23S rRNA gene internal transcribed spacer sequences.
The results suggest that phenotypic differences among Gluconobacter species are ambiguous and the species definition must be re-evaluated and the 16S rDNA and ITS sequences determined in this study are valuable for the identification and phylogenetic analysis of Glu Conobacter Species.
