Acetobacter xylinum sllbsp. sucrojlermentans BPR2001, a cellulose-producing bacterillm, that was newly isolated from a natural source, prodllced large amounts of the water-soluble po]ysaccharide, acetan. UDP-glucose is known to be the direct precllrsor in the synthetic pathways of both cellulose and acetan. We attempted to breed mutant strains and succeeded in obtalning olle, BPR3001A, which pr...

Cellulose was the most abundant polymer or polysaccharide that presents as the structural component of the primary cell wall of green plants but also signify for microbial extracellular polymer. The production of cellulose by microorganism such as Acetobacter xylinum sp. was most favored by researchers because the cellulose that produced was extremely pure and had a higher degree of polymerizat...

In a previous publication (2) evidence was presented that the synthesis of chitin in Neurospora crassa occurs by way of a glycosyl transfer from uridine diphosphate-N-acetylglucosamine. The similarity of the structure of chitin and cellulose suggested that a like mechanism may be operative in the biosynthesis of cellulose. It has been shown by Hestrin and Schramm (3) that non-viable lyophilized...

The nucleotide sequence of the Acetobacter xylinum uridine diphosphoglucose pyrophosphorylase gene was determined; this is the first procaryotic uridine diphosphoglucose pyrophosphorylase gene sequence reported. The sequence data indicated that the gene product consists of 284 amino acids. This finding was consistent with the results obtained by expression analysis in vivo and in vitro in Esche...

background bedsore is one of the major problems in all the societies as patients are confined to bed. due to antibiotic resistant strains being a significant obstacle for cure, many plants and herbs are being used by researchers as medicinal compounds. objectives the investigation of synergistic effect of cellulose biopolymer and papaver macrostomum extract on bedsores bacterial community. mate...
