A method of reducing pathogens in blood by exposure to a nitric oxide containing gas in an extracorporeal circuitry is provided. The method includes: obtaining blood from a mammal or a blood source, separating the blood into plasma and blood cells, exposing the plasma to nitric oxide containing gas, combining the exposed plasma with the blood cells, reducing nitric oxide content in the recombined blood, and returning the blood to the mammal or blood source.

A heat-shrinkable anti-fomitic device incorporating anti-microbial metal wherein the device, in the form of a bag or tube, forms a cover for an object, preventing cross-infection by bacteria and other pathogens that may reside on the object. Anti-microbial metal ions from the cover further reduce future cross-infection from the object by killing pathogens. The anti-microbial, heat-shrinkable, anti-fomitic device can have a sterile interior that is sealed or stored flat during manufacture to maintain sterility. Therefore, no outer wrapping for the anti-fomitic device is required. The anti-fomitic device can be inverted when used to cover the object to present an outer surface that is initially sterile. A plurality of such devices can be heat shrunk to an object such that removal of the outer layer will further prevent cross contamination. Heat shrink film materials for the coverings / bags serve as a barrier to the transmission of pathogens and conform closely to the covered object.

The apparatus also includes a reagent injection system for injecting a reagent into the apparatus, a mixing device for mixing the composition with the reagent, a heater system for heating the composition, or the mixture of the composition and the reagent, an internal vapor recovery system for recovering gases, vapors, and odors from the toxic materials or biosolids, or from the reagents, a reagent recovery system for recovering the reagent after it has been mixed with the composition, a discharge mechanism for discharging the treated composition, and a control panel comprising temperature and pressure measurements.

The invention relates to a preparation method of anti-stress feed for penaeus vannmei bred in a greenhouse. The preparation method comprises the following ordered steps of: clearing, weighing, primarily mixing, crudely crushing, superfinely grinding and secondarily mixing the mixture of fish meal, chicken meal, shrimp meal, sleeve-fish meal, flour and mineral elements in a certain ratio; clearing and weighing beer yeast, soya bean meal and bacillus subtilis, then equably grinding via colloid, fermenting and secondarily mixing the mixture; mixing, pelletizing and drying; emulsifying and homogenizing the mixture of glycine betaine, taurine, fish oil and vitamin, drying the surface of the semi-finished product obtained by the steps, then boiling and drying, cooling, screening, weighing and packaging to prepare the final product. The invention has the advantage that the feed is safe and healthy, has overall nutrition, is convenient to use and can promote the unshelling development of the penaeus vannmei in the greenhouse, enhance the anti-stress property and the growth performance and adjust the quality of the breeding water.

The invention discloses a preparation method of a starter feed for scophthalmus maximus linnaeus fingerlings. The preparation method comprises the following steps of (a), mixing white fish meal with chicken meat powder, beer yeast, soybean meal, flour and a mineral element mixture to obtain a mixture, crushing the mixture, blending the crushed mixture, performing puffing granulation at 100-130 DEG C, and performing drying at the temperature of 50-100 DEG C; (b), mixing egg powder with wet artemia salina and shrimp mat, performing homogenating through a colloid mill, then adding betaine, fish oil, phospholipid and a vitamin mixture, and performing emulsifying and homogenating; and (c), under vacuum, performing vacuum-spraying of emulsifying liquid obtained in the step (b) onto the surfaces of semi-finished products namely baked particles obtained in the step (a), then performing drying, performing cooling, performing crushing, performing screening, performing weighing, and performing packaging. Bioactive components of fresh living feed raw materials and bioactive components of unstable nutrient elements in a feed formula can be effectively maintained, the food calling properties and the utilization efficiency of the feed can be improved, the survival rate of the scophthalmus maximus linnaeus fingerlings can be increased, the growth properties of the scophthalmus maximus linnaeus fingerlings can be improved, pathogens in the feed are reduced, and the water-quality environment of breeding water bodies is improved.

The invention discloses a novel ruminant total mixed ration which consists of a coarse feed and a concentrated feed, wherein the coarse feed mainly comprises an alfalfa mixture and corn silage supplemented by one or more of Chinese wildrye and crop straw; the alfalfa mixture consists of alfalfa and trigonella foenum-graecum in a weight ratio of 100:(0-100); and the trigonella foenum-graecum contains 250-300g / kg of crude protein, 200-300g / kg of galactomannan, 200-250g / kg of slightly-soluble fiber, 70-90g / kg of fat and the like, and can be prepared into hay feed. The trigonella foenum-graecum can fertilize soil through nitrogen fixation and is favorable for keeping soil; the trigonella foenum-graecum also has a function of suppressing rumen flatulence and has a very high nutritive value; as a substitutive coarse feed, the alfalfa raw material can be saved, the cost of ruminant feeding is greatly reduced, the trigonella foenum-graecum resource is sufficiently utilized, and the dependence on foreign alfalfa can be eased.

A method for reducing pathogens in the gastrointestinal tract of a live animal comprising orally administering to the animal an effective amount of an aqueous antimicrobial solution, wherein the aqueous antimicrobial solution comprises from about 0.01% to about 0.1% by weight of a metal chlorite and a sufficient quantity of an acid having a first pKa of from about 2.0 to about 4.4 to adjust the pH of the aqueous antimicrobial solution to about 2.2 to about 4.5 and to maintain the chlorite ion concentration in the form of chlorous acid to not more than about 35% by weight of the total chlorite ion present in the aqueous antimicrobial solution, is disclosed.

Provided herein are methods, devices and systems comprising a reactor that is operatively connected to: (a) a biogas production unit for converting waste to a biogas stream; and (b) an engine that utilizes the biogas stream from the biogas producing unit to produce energy and an engine exhaust.

A pathogen containment shield comprises a plexiglass barrier to protect both employees on the one side of the barrier from infecting or being infected by customers on the other side of the barrier. The shield includes a vertical portion with an upper outwardly extending portion and side wings extending outwardly from the vertical portion in the direction of the customer. A hood mounted to the upper outwardly extending portion and including a tourmaline and antimicrobial infused filter, a fan designed to direct droplets into the filtration box at the base of the vertical barrier. The hood also includes an auto distance sensor and programmable auto timer to activate the fans and the filtration box when a customer approaches the shield and to turn off the operation a set time after the customer leaves. The filtration box includes a removable tourmaline and antimicrobial infused intake filter and pathogen killing UV-C light.

A system for sanitizing footwear through the use of pulsed ultraviolet (UV) light. The system can include an area that receives footwear of a user and applies a PUV light to the footwear to eliminate pathogens residing on the footwear. The system may contain a protective housing to ensure that exposure to the PUV light is limited to the footwear received in the PUV light area. The system contains electrical circuitry or control mechanism for operation of the PUV light. The system may also contain a brush area so that a user may remove dirt or solid particles from the footwear by engaging bristles that contact the underside and sides of the footwear. The intensity and the duration of the PUV light may be predetermined depending on the requirements of the facility intending to use the system.
