Demands for renewable and sustainable biopolymers have rapidly increased in the last decades along with environmental issues. In this context, bacterial cellulose, as biodegradable biopolymer has received considerable attention. Particularly, acetic acid bacteria of Komagataeibacter xylinus species can produce cellulose from several carbon sources. To fully exploit metabolic potential producing bacteria, an understanding ability different sources characterization genes involved synthesis is...
In this study, a medical device made of surface microstructured bacterial cellulose was produced using cellulose-producing acetic acid bacteria wild-type strains in combination with guided assembly-based biolithography. The aims at interfering the cell's focal adhesion establishment and maturation around implantable devices placed soft tissues by symmetrical array on its surface. A total 25 Komagataeibacter evaluated over three-step selection. first step, ability to produce suitable layer...
Bacterial cellulose (BC) is receiving a great deal of attention due to its unique properties such as high purity, water retention capacity, mechanical strength, and biocompatibility. However, the production BC has been limited because associated costs low productivity. In light this, isolation new producing bacteria selection highly productive strains become prominent issue. Kombucha tea fermented beverage in which fraction microbial community composed mostly belonging genus...
In this study, twelve strains of acetic acid bacteria (AAB) belonging to five different genera were tested for their ability produce levan, at 70 and 250 g/L sucrose concentration, respectively. The fructan produced by the bacterial was characterized as levan NMR spectroscopy. Most highlighting intra- inter-species variability. High yield observed Neoasaia chiangmaiensis NBRC 101099 T, Kozakia baliensis DSM 14400 T Gluconobacter cerinus 9533 sucrose. A 12-fold increase N. concentration....
Among naturally produced polymers, bacterial cellulose is receiving enormous attention due to remarkable properties, making it suitable for a wide range of industrial applications. However, the low yield, instability microbial strains and limited knowledge mechanisms regulating metabolism producer strains, limit large-scale production cellulose. In this study,
In this study, a co-culture system combining bacterial cellulose (BC) producers and hyaluronic acid (HA) was developed for four different combinations. AAB of the genus Komagataeibacter sp. LAB Lactocaseibacillus were used to produce BC HA, respectively. Fourier-transform infrared spectroscopy, scanning electron microscopy, X-ray diffraction investigate changes in BC-HA composites chemical morphological structure. Water absorption, uptake, antibacterial properties also tested. Outcomes...

A Ciboria sp. strain (Phylum Ascomycota) was isolated from hydrocarbon-polluted soil of an abandoned oil refinery in Italy. The able to utilize diesel as a sole carbon source for growth. Laboratory-scale experiments were designed evaluate the use this fungal treatment polluted soil. concentration total petroleum hydrocarbons (TPH) 8,538 mg/kg. Mesocosms containing contaminated inoculated with at 1 or 7%, on fresh weight base ratio. After 90 days incubation, depletion TPH contamination 78% 1%...
The recovery of yeasts and lactic acid bacteria (LAB) involved in sourdough fermentation is the first step selection starters with suitable technological aptitude capable producing desired aromas and/or aromatic precursors. In this work, two sourdoughs samples (MA MB) derived doughs (samples A B) were collected from a bakery during artisanal Panettone manufacture. Yeasts isolated at different steps on selective agar media. total 77 isolates obtained characterized. Representative strains LAB...
This study demonstrated that a microbial community dominated by fungi can be selected and maintained in the long-term under non-sterile conditions, pilot-scale packed-bed reactor fed with tannery wastewater. During start-up phase, reactor, filled 0.6 m3 of polyurethane foam cubes, was inoculated pure culture Aspergillus tubingensis Quebracho tannin, recalcitrant compound widely used industry, as sole carbon source feeding. start-up, grew attached biofilm carriers reactor. Subsequently,...
Rice germination and seedlings' growth are crucial stages that influence crop establishment productivity. These performances depend on several factors, including the abundance diversity of seed microbial endophytes. Two popular rainfed rice varieties cultivated in Cameroon, NERICA 3 8, were used for investigating seed-associated microbiome using Illumina-based 16 S rRNA gene. Significant differences observed terms richness index between normal abnormal seedlings developed from sprouting...
In this study, spore-forming bacteria isolated from saccharified rice were selected for producing acetic acid. From the screening of 15 strains, P8 strain was chosen as a candidate. The identified Paenibacillus azoreducens by 16S rRNA analysis (99.85% similarity with P. CM1T). Acetic acid is main component vinegar but also an industrial commodity produced chemical synthesis. Sustainable routes obtaining are great interest decreasing environmental impact generated syntheses. Biological...
A new halo-alkaline sulfur-oxidising bacterial strain was isolated from brackish estuary sediments contaminated by total petroleum hydrocarbon. The isolate classified as a of Thioalkalivibrio sulfidiphilus sp., showing higher capability adaptation to pH and optimal sodium concentration for growth, when compared sp. HL-EbGr7, type the species. capable grow in saline concentrations up 1.5 M Na+ 10. genome sequenced annotated. comparison with HL-EbGr7 showed duplication an operon encoding...
