protein recovery under sonication treatment and autolysis, also protein hydrolysis progress during enzymatic hydrolysis (using trypsin and chymotrypsin) and autolysis (using endogenous enzymes) were investigated in saccharomyces cerevisiae and kluyveromyces marxianus. crude protein content of dried yeast cells were 53.22% and 45.6% for s.cerevisiae and k.marxianus, respectively. after 96 hrs of...
The effect of 20 kHz ultrasound on the viability of Cryptosporidium oocysts was investigated. More than 90% of the dispersed Cryptosporidium oocysts could be deactivated in about 1.5 min of continuous sonication. In order to apply this technique to large quantities of contaminated water, quantitative filtration and redispersion of Cryptosporidium oocysts were investigated and found to be easily...
Background and Objectives: Preparation and evaluation of nanocomposite films have become prevalent in recent years. One of the most important methods for dispersing nanoparticles in polymers is the use of ultrasound radiation. Polyvinyl alcohol-montmorillonite (PVA-MMT) nanocomposite films were prepared via solvent casting method. Materials and Methods: The effects of different ultrasound ti...
Previous studies have shown that sonication fluid cultures from removed orthopedic devices improved the microbiological diagnosis of orthopedic implant-associated infections; however, few of these investigations have applied sonication to the removed fracture fixation devices to evaluate its utility for the diagnosis of osteosynthesis-associated infection (OAI). We compared sonication fluid to ...
The Food Technology group of the University of Zaragoza has investigated the effect of ultrasound and its combination with other factors on the microbial inactivation since the early 90’s. Our group designed an equipment that allows to apply ultrasound under pressure treatments at sublethal (Mano-Sonication; MS), and at lethal temperatures (Mano-Thermo-Sonication; MTS) to liquid products. The i...
20 Previous studies have shown that sonication-fluid cultures from removed devices improved the 21 microbiological diagnosis of orthopedic implant-associated infections; however, few of these 22 investigations have applied sonication to the removed fracture-fixation devices to evaluate its 23 utility as an adjunctive diagnostic tool for osteosynthesis-associated infection (OAI). We 24 compared ...
Various washing protocols have been assessed for efficacy using Agilent LC/MS and GC/MS instrumentation to measure pesticide residues in tomatoes and other produce. Washing procedures in water and various solutions, with and without sonication, were evaluated in the laboratory. In general, the effect of sonication depended on the washing treatment and on the pesticide. A separate experiment mea...
