Abstract: The objective of this work is to verifying the consume of the minerals K, Na, Fe, Mg, P, S-SO4−2, B, N Total Kjedahl (NTK), NO3−-N, and NH4+-N in the production of bacterial cellulose by Acetobacter xylinum, according to the medium and the manner of cultivation. The fermentative process was in ripe and green coconut water. K and Na were determined by flame emission photometry, Mg and Fe by atomic absorption spectrophotometry, P by molecular absorption spectrophotometry, S-SO4−2 by barium sulphate turbidimetry,… Show more

“…13 This biopolymer has similar characteristics to cellulose polymer of a vegetable origin, but it differs in terms of the degree of polymerization and purity and has more stable, resistant nanofibers with an ultra-fine reticular structure, high crystallinity, tensile strength, elasticity, and durability. 4,5…”

“…[1][2][3] This biopolymer has similar characteristics to cellulose polymer of a vegetable origin, but it differs in terms of the degree of polymerization and purity and has more stable, resistant nanofibers with an ultra-fine reticular structure, high crystallinity, tensile strength, elasticity, and durability. 4,5 Cellulose can be produced by algae, fungi, protozoa, and prokaryotic organisms. 6 Among the producers of BC, bacteria of the genus Komagataeibacter (recently reclassified from the genus Gluconacetobacter based on the phylogenetic, phenotypic, ecological, and chemotaxonomic characteristics of the 16S rRNA sequence) are gaining prominence in the production of this biopolymer of considerable scientific value.…”

“…However, only a few studies have been conducted on UV technology to mutate A. xylinum in order to reduce problems, such as low fermentative yield, instability and high material cost of BC fermentation. Moreover, the coconut milk of medium nutrients was an important part because the content of Na + , NO 3 ‐ , NH 4 + and SO 4 2− had a significant effect on the yield of BC (Almeida et al , ). Coconut milk has a potential use in the fabrication of membranes by converting it to bacterial cellulose and then to cellulose diacetate (Radiman & Yuliani, ).…”
