Performance of a growth-No growth model for Listeria monocytogenes developed for mayonnaise-based salads: Influence of strain variability, food matrix, inoculation level, and presence of sorbic and benzoic acid
(Int Assoc Food Protection, Des Moines, 2007)
A previously developed growth-no growth model for Listeria monocytogenes, based on nutrient broth data and describing the influence of water activity (a(w)), pH, and acetic acid concentrations, was validated (i) for a ...
Petroleum pollutant degradation by surface water microorganisms
(Springer Heidelberg, Heidelberg, 2006)
BACKGROUND: , Aims and Scope. It is well known that the composition of petroleum or some of its processing products changes in the environment mostly under the influence of microorganisms. A series of experiments was ...
Physical-mechanical properties of nitrodopes affected by ultra-violet radiation
(MDPI, BASEL, 2007)
The FTIR spectroscopy has been employed in this research work to monitor the process of nitrodope photodegradation, by measuring surfaces of bands typical of a nitro group. Nitric esters are subject to degradation, which ...
Permeate flux and fouling resistance in ultrafiltration of depectinized apple juice using ceramic membranes
(Elsevier Sci Ltd, Oxford, 2003)
Raw depectinized apple juice was clarified in a laboratory scale ultrafiltration system using ceramic tubular membranes (Tech-Sep Carbosep) with a molecular weight cut-off of 300,000, 50,000, and 30,000 Da. The experiments ...
Survival of listeria monocytogenes and Escherichia coli O157 : H7 during Sauerkraut fermentation
(Int Assoc Food Protection, Des Moines, 2005)
Sauerkraut was produced from shredded cabbage, as is typical in the United States, and from whole head cabbages, which is a traditional process in parts of Eastern Europe. The sauerkraut was inoculated with five strain ...
Influence of ventilation systems and related energy consumption on inhalable and respirable dust concentrations in fattening pigs confinement buildings
(Elsevier Science Sa, Lausanne, 2005)
In this paper are presented the results of experimental analysis of the influence of ventilation systems and related energy consumption on inhalable and respirable dust concentrations in fattening pigs confinement buildings. ...
The accuracy of turbulent velocity component measurements by multi-sensor hot-wire probes: a new approach to an old problem
(Springer, New York, 2003)
The measurement accuracy of different hot-wire probes possessing between two and 12 sensors is analyzed. Experimental data were sampled in a round free jet and in a zero-pressure-gradient turbulent boundary layer by a ...
An analytical approach to the uniqueness problem of hot-wire probes to measure simultaneously three velocity components
(IOP Publishing Ltd, Bristol, 2004)
The uniqueness range of hot-wire probes to simultaneously measure all three velocity components is analysed analytically. Expressions defining the uniqueness cone half-angle are presented for triple as well as for quadruple ...
Oak acorn, polyphenols and antioxidant activity in functional food
(Elsevier Sci Ltd, Oxford, 2006)
In this paper, are presented the results of physical and chemical investigations of differently treated samples of oak acorn. The aim of this investigation is to estimate the influence of thermal treatment on physical and ...
Comparative study of batch and continuous multi-stage fixed-bed tower (MFBT) bioreactor during wine-making using freeze-dried immobilized cells
(Elsevier Sci Ltd, Oxford, 2009)
A freeze-dried immobilized biocatalyst produced by immobilization of Saccharomyces cerevisiae AXAZ-1 yeast cells on gluten pellets and subsequent freeze-drying was used in a multistage fixed-bed tower (MFBT) bioreactor for ...
