16S rRNA-Based Identification of a Glucan-Hyperproducing Weissella confusa
A gram-positive, nonmotile, irregular, short, rod-shaped new strain of Weissella confusa bacterium was isolated from fermented cabbage. The isolate was physiologically and biochemically characterised. The 16S rDNA was amplified by polymerase chain reaction (PCR). The isolate was identified as Weissella confusa (GenBank accession number: GU138518.1) based on nucleotide homology and phylogenetic ...
متن کاملScreening of lactic acid bacteria from Indonesia reveals glucansucrase and fructansucrase genes in two different Weissella confusa strains from soya.
Homopolysaccharide (glucan and fructan) synthesis from sucrose by sucrase enzymes in lactic acid bacteria (LAB) has been well studied in the genera Leuconostoc, Streptococcus and Lactobacillus. This study aimed to identify and characterize genes encoding glucansucrase/glucosyltransferase (GTF) and fructansucrases/fructosyltransferase (FTF) enzymes from genomic DNA of 'rare' Indonesian exopolysa...
متن کاملDraft Genome Sequence of Weissella confusa MBF8-1, a Glucansucrase- and Bacteriocin-Producing Strain Isolated from a Homemade Soy Product
We report here the draft genome sequence of Weissella confusa MBF8-1, an isolate from a homemade fermented soybean product that produces sucrases and exhibits antibacterial (bacteriocin) activity. The draft genome of W. confusa MBF8-1 comprises a 2.2-Mbp chromosome and a 17.8-kbp bacteriocin-encoding plasmid. Two putative glucansucrase genes were also identified.
متن کاملDevelopment of Efficient Fermentation Process at Bioreactor Level by Taguchi's Orthogonal Array Methodology for Enhanced Dextransucrase Production from Weissella confusa Cab3
The influence of medium ingredients on extracellular dextransucrase production by a new bacterial strain Weissella confusa Cab3 (Genbank Accession Number JX649223) was evaluated using fractional factorial design of Taguchi’s orthogonal array. Four metabolism influencing factors viz. sucrose, yeast extract, K2HPO4 and Tween80 were selected to optimize dextransucrase production by W. confusa Cab3...
متن کاملGreen Synthesis of Silver Nanoparticles Using Dextran from Weissella Confusa
Dextran a polymer of glucose is produced by different microorganisms like Leuconostoc mesenteroides, Lactobacillus sps, Streptococcus mutants, Weissella confusa etc. It has a wide range of applications in the food, pharmaceuticals and other industries. It also has significant role in green synthesis of silver nanoparticles. In the present study an efficient low molecular dextran produced by an ...
