The integrity and morphology of bacteria is sustained by the cell wall, the target of the main microbial inactivation processes. One promising approach to inactivation is based on the use of pulsed electric fields (PEF). The current dogma is that irreversible cell membrane electro-permeabilisation causes the death of the bacteria. However, the actual effect on the cell-wall architecture has bee...
Membrane permeabilization due to pulsed electric field (PEF) treatment of gram-positive Lactobacillus cells was investigated by using propidium iodide uptake and single-cell analysis with flow cytometry. Electric field strength, energy input, treatment time, and growth phase affected membrane permeabilization of Lactobacillus plantarum during PEF treatment. A correlation between PEF inactivatio...
In this investigation, the influence of the application of pulsed electric fields (PEFs) of different intensities (3-7 kV/cm and 0-300 μs) on the carotenoid extraction from tomato peel and pulp in a mixture of hexane:acetone:ethanol was studied with the aim of increasing extraction yield or reducing the percentage of the less green solvents in the extraction medium. According to the cellular di...
BACKGROUND Objective measures are required that may be used as a proxy for exacerbations in asthma. The aim was to determine the sensitivity and specificity of electronic diary data to detect severe exacerbations (SEs) of asthma. A secondary aim was to identify phenotypic variables associated with a higher risk of exacerbation. METHODS In the BIOAIR study, 169 patients with asthma (93 severe ...
Listeriosis is an emerging infection with major public health concerns worldwide because of occurrence associated food-borne outbreak and significant risk mortality morbidity. This study aimed to isolate Listeria monocytogenes in raw meat samples selected markets Nasarawa State, determine the level contamination, as well antibiogram isolates. A total 60 were collected from different animals, in...
