This work focuses on the treatment of washing waters coming from surimi manufacturing using ultrafiltration technology at a laboratory scale. Four membrane materials (poly-ether sulfone, polyacrilonytrile, poly vinylidene fluoride and regenerated cellulose) and 5 Molecular Weight Cut-Off (from 3 to 100 kDa) have been studied at bench laboratory scale using the pilot Rayflow 100, commercialised ...

PURPOSE To analyze the effectiveness of bacterial cellulose hydrogel as a barrier in preventing postoperative peritoneal adhesion in rat model. METHODS Experimental study with 45 Wistar rats (Rattus norvegicus) that were divided into three groups for the following treatments: A. Saline, B. Oxidized Regenerated Cellulose (ORC) barrier, and C Bacterial Cellulose Hydrogel (BCH) barrier. After 45...

Bacterial cellulose is a biological polymer with a variety of extraordinary properties which make it a functional material for different industrial fields. This work aimed at monitoring the effects of three different organic acids and nanoparticles on the production, water holding capacity and structural characteristics of bacterial cellulose. Different concentrations of organic acids and nanop...

A previous report indicated that a formic acid chemical extraction method for the preparation of protein extracts for matrix-assisted laser desorption time-of-flight mass spectrometry (MALDI-TOF MS) identification, with filtration of extracts through 0.2 μm regenerated cellulose (RC) filters, would not reliably inactivate or exclude Bacillus anthracis Vollum cells or spores when tested under hi...
