Growth from spores of nonproteolytic Clostridium botulinum in heat-treated vegetable juice. (1/249)

Unheated spores of nonproteolytic Clostridium botulinum were able to lead to growth in sterile deoxygenated turnip, spring green, helda bean, broccoli, or potato juice, although the probability of growth was low and the time to growth was longer than the time to growth in culture media. With all five vegetable juices tested, the probability of growth increased when spores were inoculated into the juice and then heated for 2 min in a water bath at 80 degrees C. The probability of growth was greater in bean or broccoli juice than in culture media following 10 min of heat treatment in these media. Growth was prevented by heat treatment of spores in vegetable juices or culture media at 80 degrees C for 100 min. We show for the first time that adding heat-treated vegetable juice to culture media can increase the number of heat-damaged spores of C. botulinum that can lead to colony formation.  (+info)

Vaccine storage in the community: a study in central Italy. (2/249)

Maintaining the vaccine cold chain is an essential part of a successful immunization programme, but in developed countries faulty procedures may occur more commonly than is generally believed. A survey was conducted in a health district in central Italy to assess the methods of vaccine transportation and storage. Of 52 primary vaccination offices inspected, 39 (76.5%) had a refrigerator for vaccine storage but only 17 (33.3%) kept records of received and stored doses. None of the seven main offices selected for monitoring had a maximum and minimum thermometer and none monitored the internal temperature of the refrigerator. Moreover, other faulty procedures, such as the storage of food and laboratory specimens in vaccine refrigerators and the storage of vaccines on refrigerator door shelves, indicated that the knowledge and practice of vaccine storage and handling were often inadequate.  (+info)

Bacterial resistance of refrigerated and cryopreserved aortic allografts in an experimental virulent infection model. (3/249)

PURPOSE: The bacterial resistance of refrigerated and cryopreserved aortic allografts in a highly virulent infection in a dog model was studied. METHODS: The infrarenal aorta of 12 dogs was replaced with either a cryopreserved aortic allograft (group I, n = 6) or a refrigerated aortic allograft (group II, n = 6) in infected sites. Allografts were harvested from dogs and stored for 1 week, either by cryopreservation (-140 degrees C) or refrigerated method (4 degrees C), in a preservation medium. At the time of implantation, induction of infection was achieved with an infected piece of knitted Dacron placed just beneath the allograft. The Dacron was contaminated in vitro by soaking it in a solution with Staphylococcus aureus PR209. All 12 dogs received no adjunct antibiotic or antithrombotic therapy. Four weeks after implantation, the animals were killed to recover the grafts for bacteriological and histological analyses. Bacterial results were expressed as colony-forming units (CFU)/cm2 of graft material. RESULTS: In group I, only one allograft grew bacteria at 2. 16 x 10(6 )CFU/cm2, with a blood culture positive for S aureus. In group II, one dog died at 3 weeks from a false septic aneurysm rupture, all the allografts were infected (P <.05) with a mean bacterial count of 9.41 +/- 6.8 x 10(4) CFU/cm2, and three blood cultures were positive for S aureus. The patency of the grafts was analyzed at the time of recovery. Three laminar thrombi without occlusion were present in group I; none were present in group II. A better preserved endothelium in group I was revealed by means of histologic analysis staining with factor VIII antibody before implantation. After 4 weeks of implantation in the infected site, infected allografts presented polynuclear infiltrates in the media with a high degree of inflammatory reaction, and endothelial recovery was more significant in group I, with numerous young plump cells. CONCLUSION: This study demonstrates that cryopreserved allografts implanted in infected sites in a dog model can produce greater bacterial resistance.  (+info)

A predictive model that describes the effect of prolonged heating at 70 to 90 degrees C and subsequent incubation at refrigeration temperatures on growth from spores and toxigenesis by nonproteolytic Clostridium botulinum in the presence of lysozyme. (4/249)

Refrigerated processed foods of extended durability such as cook-chill and sous-vide foods rely on a minimal heat treatment at 70 to 95 degrees C and then storage at a refrigeration temperature for safety and preservation. These foods are not sterile and are intended to have an extended shelf life, often up to 42 days. The principal microbiological hazard in foods of this type is growth of and toxin production by nonproteolytic Clostridium botulinum. Lysozyme has been shown to increase the measured heat resistance of nonproteolytic C. botulinum spores. However, the heat treatment guidelines for prevention of risk of botulism in these products have not taken into consideration the effect of lysozyme, which can be present in many foods. In order to assess the botulism hazard, the effect of heat treatments at 70, 75, 80, 85, and 90 degrees C combined with refrigerated storage for up to 90 days on growth from 10(6) spores of nonproteolytic C. botulinum (types B, E, and F) in an anaerobic meat medium containing 2,400 U of lysozyme per ml (50 microg per ml) was studied. Provided that the storage temperature was no higher than 8 degrees C, the following heat treatments each prevented growth and toxin production during 90 days; 70 degrees C for >/=2,545 min, 75 degrees C for >/=463 min, 80 degrees C for >/=230 min, 85 degrees C for >/=84 min, and 90 degrees C for >/=33.5 min. A factorial experimental design allowed development of a predictive model that described the incubation time required before the first sample showed growth, as a function of heating temperature (70 to 90 degrees C), period of heat treatment (up to 2,545 min), and incubation temperature (5 to 25 degrees C). Predictions from the model provided a valid description of the data used to generate the model and agreed with observations made previously.  (+info)

Influence of refrigeration and formalin on the floatability of Giardia duodenalis cysts. (5/249)

Giardia duodenalis cysts obtained from fresh fecal samples, fecal samples kept under refrigeration and fecal samples treated with formalin were studied as to their floatability on sucrose solutions with the following specific gravities: 1,040 kg/m3; 1,050 kg/m3; 1, 060 kg/m3; 1,070 kg/m3; 1,080 kg/m3; 1,090 kg/m3; 1,100 kgm3; 1,150 kg/m3; 1,200 kg/m3; and 1,250 kg/m3, contained within counting-chambers 0.17 mm high. Cysts that floated on and those settled down as sediments were counted, and had their percentages estimated. Sucrose solutions of 1,200 kg/m3 specific gravity (the average specific gravity of diluting liquids employed in floatation techniques) caused to float 77.7%, 78.4% and 6.6% of the G. duodenalis cysts obtained, respectively, from fresh fecal samples, fecal samples kept under refrigeration, and fecal samples treated with formalin. Cysts obtained both from fresh fecal samples and fecal samples kept under refrigeration presented similar results concerning floatability. It was observed, however, that the treatment of feces with formalin diminished the cysts floatability under the various specific gravities studied. This results should influence, the recommendations for transport and storage of fecal samples used for parasitological coproscopy.  (+info)

High-resolution gas chromatographic profiles of volatile organic compounds produced by microorganisms at refrigerated temperatures. (6/249)

Three different strains of bacteria isolated from spoiled, uncooked chicken were grown in pure culture on Trypticase soy agar supplemented with yeast extract. The volatile organic compounds produced by each culture were concentrated on a porous polymer precolumn and analyzed by high-resolution gas chromatographic mass spectrometry. Twenty different compounds were identified. Both qualitative and quantitative differences in the chromatographic profiles from each culture were found.  (+info)

Fertility of mouse spermatozoa retrieved from cadavers and maintained at 4 degrees C. (7/249)

After male animals die, the spermatozoa within the testis and epididymis eventually disintegrate. In this study, the motility, viability and fertility of mouse spermatozoa were examined after retrieval from the epididymis at various days after death. Cadavers were maintained in a refrigerator at 4 degrees C. About 30% of the spermatozoa collected 10 days after death were viable, but they had limited ability to fertilize oocytes in vitro. However, when the spermatozoa were injected into oocytes, the fertilization rate was over 80%. Normal live fetuses were even obtained using immotile spermatozoa retrieved 20 days after death. Therefore, when valuable male animals die unexpectedly and sperm cryopreservation is not possible immediately, temporal storage of cadavers (or epididymis and vas deferens) at 4 degrees C in a regular refrigerator followed by intracytoplasmic sperm injection may help to preserve the genome of individuals. This procedure could be particularly important in endangered species.  (+info)

Survival of the human granulocytic ehrlichiosis agent under refrigeration conditions. (8/249)

The human granulocytic ehrlichiosis (HGE) agent in infected blood specimens remained viable during refrigeration at 4 degrees C for up to 18 days. These findings suggest that blood specimens submitted for culture may withstand transportation to a remote laboratory. HGE should be added to the list of infections potentially transmitted by blood transfusion.  (+info)

The cycle characteristics of thermochemical resorption refrigeration system were investigated, and the experimental comparison between the basic resorption cycle and adsorption cycle was performed. Experimental results showed that the conversion rate during the regeneration phase in the resorption refrigeration cycle was higher than that in the adsorption refrigeration cycle at the same constraining temperatures. However, the conversion rate was lower during the cold production phase in the former cycle than in the latter cycle. Moreover, the reaction plateau temperature in the resorption cycle was lower than that in the adso rption cycle at the same regeneration temperature and heat sink temperature. The thermal capacity of metallic part of reactor has a stronger influence on the system performance for the resorption cycle compared with the adsorption cycle.

In this paper, the performance of the solar-driven ejector refrigeration system with iso-butane (R600a) as the refrigerant is studied. The effects that both the operating conditions and the solar collector types have on the systems performance are also examined by dynamic simulation. The TRNSYS and EES simulation tools are used to model and analyze the performance of a solar-driven ejector refrigeration system. The whole system is modelled under the TRNSYS environment, but the model of the ejector refrigeration subsystem is developed in the Engineering Equations Solver (EES) program. A solar fraction of 75% is obtained when using the evacuated tube solar collector. In the very hot environment, the system requires relatively high generator temperature, thus a flat plate solar collector is not economically competitive because the high amount of auxiliary heat needed to boost up the generator temperature. The results from the simulation indicate that an efficient ejector system can only work in a ...

Understanding The Standard Of The Refrigeration Cycle Refrigeration cycle or thermostatic cycles are the mathematical as well as conceptual designs for hot air compression, refrigeration, and air cooling systems. Essentially, a hot air compressor is a device that permits the transmission of cool air from one place to an additional place at a lower temperature. The compression of air occurs in a closed cycle, implying that as the compressed gas reaches a temperature of cold, it increases. As it increases, the quantity also gets up until the expanding gas is cooled again. A closed-cycle refrigeration cycle is a vital part of a refrigerator because it saves money on power intake. This is because throughout the compression phase of this procedure, refrigerators or various other means of refrigeration are utilized. This is the most vital part of the entire refrigeration cycle. Chilling is important in this process because it slows down the expansion of the gas as well as it likewise makes the ...
The refrigeration system removes heat from an area that is low-pressure, low temperature (evaporator) into an area of high-pressure, high temperature (condenser). (Fig. T-s diagram of refrigeration cycle (c) Constant entropy line represents isentropic or adiabatic (reversible) process. Undercooling of the liquid is generally along the constant pressure line. For this purpose an expansion device is provided at point between condenser and evaporator. 36.23. Figure 36.21 shows on T-S diagram for the equipment arrangement of Fig. If it were allowed to boil as it is, it will do so at the saturation temperature and will require heat to be supplied to it.

I have been very curious to know more of effects of the far infrared lamp, since my wife brought a new refrigerator ( goldstar). The refrigerator has a far infrared lamp in the top of the food compartment, the aim of this lamp is to preserve meat with out freezing, we left some fresh beef for two weeks and it did not have any change in smell and color. We eat it without any complaint the next day. I have performed some of the next home experiments: I introduced a thermometer inside the fridge to check a difference of one degree (centigrade) on temperature on the surface of the meat when the infrared lamp is on and off. I wrapped three pieces of meat, one with aluminum, one with transparent plastic film and another in side a glass bottle, the only one that survived was the piece inside the plastic film. It seems to me that there is a green house effect??? The refrigerator manual says that infrared rays keeps the taste and the smell of the food for long by increasing the nucleic acid. (I have not ...

One of Umpquas first energy upgrades involved overhauling its ammonia refrigeration system, which could not keep up with expanding demand. Refrigeration is responsible for most of our energy consumption, so we invest in these projects because thats where we get the greatest savings, said John Harvey, director of plant operations, Umpqua Dairy. Energy Trust helped replace two small compressors with a large energy-efficient model and install a new control system to ensure optimal production temperatures. When it was time to replace production ice cream freezers, Umpqua turned to Energy Trust for help installing three new high-efficiency freezers that reduced annual energy use by 350,000 kilowatt hours. Later, a new ice cream mixing room tripled capacity using the latest in energy-efficient equipment. Occupancy sensors and new LED technology have improved lighting in offices and production areas. The ongoing quest to conserve resources led Umpqua to its latest project, participating in Energy ...

People have been fermenting vegetables for centuries to increase the stability of fresh foods, to make the foods safer to eat in the absence of refrigeration and to enhance their flavor. Today, vegetable fermentation is done on a large-scale setting in factories as well as in households across the world. In the United States, the primary vegetables fermented are cucumbers (pickles), cabbage (sauerkraut and Kimchi) and olives. In many parts of the world, especially in developing countries where refrigeration is not common, fermented foods constitute a major portion of the diet. During vegetable fermentation, mainly bacteria and, at times, yeast break down vegetable sugars into acid, carbon dioxide gas and other flavor compounds. The acid produced gives the vegetable tartness and also keeps the food safe by preventing harmful bacteria from growing. The acid and carbon dioxide also keeps spoilage microorganisms from growing so fermented vegetables can last much longer than their fresh counterparts. ...
When I was growing up on my parents farm in East Texas, we never thought about food poisoning or unsafe food. The only foods we bought were sugar, salt, flour, and oatmeal; everything else we produced and preserved on the farm. My mother spent all summer canning fruits and vegetables for winter. We had no refrigeration; we cured our own meat and drank raw milk. But I never heard of botulism, staph poisoning, or salmonellosis or perfringens poisoning until I studied bacteriology in college. Only then did I wonder how we survived with no refrigeration in a hot climate. Finally, the answer came to me. We just did not give the bacteria time enough to develop so they could hurt us. Leftovers from breakfast hot biscuits, eggs, ham, bacon or sausage, oatmeal, coffee or milk went right out to the chickens. Lunch leftovers biscuits, cornbread, vegetables, or fried chicken were saved for a cold supper 4 or 5 hours later. Any food left went to the pigs. The bacteria had only a maximum of 3 or 4 hours to ...

Plastic resin production. The raw material for all packaging plastics is ethylene. Ethylene is a gas derived from natural gas or from a fraction of crude oil that has a composition similar to natural gas. Both natural gas and crude oil are products of fossils and are therefore not renewable.. Producing and refining ethylene uses a lot of energy, requiring combustion to achieve high reaction temperatures and refrigeration to achieve extremely low temperatures to condense and separate gases (reaching about -260 degrees Fahrenheit). Largely because refrigeration is inherently mechanically inefficient, producing ethylene consumes at least 20 megajoules (MJ) per kilogram of ethylene produced. , Twenty MJ would run a 100-watt light bulb for 56 hours. Much of this energy is generated at the production site by burning some of the feedstock of natural gas or crude oil. Therefore, producing plastics for packaging uses nonrenewable resources to heat and refrigerate as well as feedstock. This is a resource ...

What about buying refrigerated probiotics from stores such as Walgreens, Walmart, CVS, Whole Foods, Bigamin Shoppe, GNC, and Costco?. Purchasing probiotics from large chain outlets like these is not recommended, due to the handling and transporting of mass shipments that may not have been handled appropriately.

HVAC (stands for Heating, Ventilation and Air Conditioning) is a control system that applies regulation to a heating and/or air conditioning system. Usually a sensing device is used to compare the actual state (e.g., temperature) with a target state. Then the control system draws a conclusion what action has to be taken (e.g., start the blower). |br|More complex HVAC systems can interface to Building Automation System (BAS) to allow the building owners to have more control over the heating or cooling units.

The adsorption solar-powered cooling system is one of several types of solar-powered cooling systems currently under development. Increasing the efficiency and decreasing the cost of this system will make it a commercially viable alternative to traditional refrigeration systems. The objective of this project was to optimize the adsorber in the adsorption system. A mathematical model of the refrigerant distribution within a cylindrical adsorber was developed using equations from Chua et al. [1]. The simulation revealed effects of varying design parameters on the theoretical refrigerant mass flow rate, which is directly proportional to the system refrigeration capacity. These results indicated parameter values to be used in designing the adsorber. It was found that decreased particle radius, decreased bed porosity, increased pipe radius, increased adsorber radius, and increased fin thickness all positively affect the performance of the adsorption system. Further simulation and experimental trials ...
