Abstract Microbial fuel cells (MFC) are of great interest for new sources renewable energies from the waste biomass and debris. This work aimed was to develop an anode electrode carbon fiber‐embedded bacterial cellulose/polyaniline (CF/BC/PANI) nanocomposite MFC applications. For this purpose, fiber wrapped onto cellulose (BC) fibers network during BC synthesis. The CF/BC/PANI obtained by polyaniline polymerization on nanofibers as a scaffold. To characterize electrode, scanning electron...
Bacterial cellulose (BC) is a biopolymer with interesting properties, such as biocompatibility, high tensile strength, absorption capacity, water retention and crystallinity. Nanoparticles of titanium dioxide (TiO 2 ) are extremely important in electrical applications, photocatalysis, sensors biomedical areas. Multifunctional materials, based on bacterial cellulose, differentiated properties can be designed from the BC/TiO nanocomposite by ex situ method sol-gel immersion. It was...
Summary The aim of this study was to determine the physico‐chemical, microbiological, rheological and sensory characteristics sugar cane juice with passion fruit pulp (5% w/w) added which had been submitted microfiltration pasteurisation (90 °C/30 s; 95 s) processes. results showed that juices obtained after processes low microbial counts. microfiltered a reduction in soluble solids, acidity vitamin C content ( P = 0.05), while pasteurised no change these parameters > 0.05) relation...
Bacterial cellulose (BC) is a polymer produced by some bacteria and it highly pure when compared to plant cellulose. Its structure properties are unique, which makes material of large commercial interest due its broad potential applications. The biosynthesis BC may be carried out in two ways either static or agitated culture. Static culture usually generates membranes whereas tends produce spherical shapes. production often enables an increase yield for production. However, provides with...
Bacterial cellulose nanocrystals are highly crystalline structures with nanoscopic scale dimensions that have received increased attention in the nanocomposites area. Its properties, such as large surface area, low density, mechanical strength and ease of modification, attractive to preparation many kinds nanomaterials applied multifunctional various fields. Besides, from abundant renewable sources biodegradable. An altemative method is obtain bacterial nanocrystal by enzymatic hydrolysis...
Tryptophan is an aromatic amino acid used for protein synthesis and cellular growth. Chromobacterium violaceum ATCC 12472 uses two tryptophan molecules to synthesize violacein, a secondary metabolite of pharmacological interest. The genome analysis this bacterium revealed that the genes trpA-F pabA-B encode enzymes pathway in which first reaction conversion chorismate anthranilate by synthase (AS), enzyme complex. In present study, organization structure AS subunits from C. were analyzed...
