Computer simulation of Clostridium botulinum strain 56A behavior at low spore concentrations.
It is generally assumed that spore behavior is independent of spore concentration, but recently published mathematical models indicate that this is not the case. A Monte Carlo simulation was employed in this study to further examine the independence assumption by evaluating the inherent variance in spore germination data. All simulations were carried out with @Risk software. A total of 500 to 4...
متن کاملEvidence for quorum sensing in Clostridium botulinum 56A.
AIMS Experiments were designed to detect quorum-sensing signals produced by Clostridium botulinum. METHODS AND RESULTS Clostridium botulinum 56A cell-free supernatants obtained at the end of lag phase, the mid-exponential phase and early stationary phase of growth were assayed for bioluminescence in the Vibrio harveyi quorum-sensing assay system. Twelve and 16-h culture supernatants induced b...
متن کاملQuantification of Nonproteolytic Clostridium botulinum Spore Loads in Food Materials
We have produced data and developed analysis to build representations for the concentration of spores of nonproteolytic Clostridium botulinum in materials that are used during the manufacture of minimally processed chilled foods in the United Kingdom. Food materials are categorized into homogenous groups which include meat, fish, shellfish, cereals, fresh plant material, dairy liquid, dairy non...
متن کاملTime-to-detection, percent-growth-positive and maximum growth rate models for Clostridium botulinum 56A at multiple temperatures.
We previously developed models for the influence of inoculum size on the growth kinetics (time-to-detection and maximum growth rate) and percent-growth-positive samples of Clostridium botulinum 56A with factors of inoculum size (1, 100, and 10,000 spores/sample). pH (5.5. 6.0 and 6.5) and sodium chloride concentration (0.5%, 2% and 4%) at 30 degrees C. In this present study, data were collected...
متن کاملComputer Simulation of Hydrodynamic Behavior of Aggregative Fluidized Beds
Hydrodynamic behavior of aggregative fluidized beds has been studied and a model proposed for the prediction of different characteristics of fluidized beds. According to this model, a computer program is prepared and the hydrodynamic behavior of some industrial units has been simulated.
