  • Patent number: 5637499
    Abstract: A method of enhancing the bacterial reduction of industrial gases using perfluorocarbons (PFCs) is disclosed. Because perfluorocarbons (PFCs) allow for a much greater solubility of gases than water does, PFCs have the potential to deliver gases in higher concentrations to microorganisms when used as an additive to microbial growth media thereby increasing the rate of the industrial gas conversion to economically viable chemicals and gases.

  • Patent number: 5629169
    Abstract: A method and apparatus for estimating drug effectiveness from a drug diffusion sample are provided. The drug diffusion sample includes a plate having a medium containing a test organism and a plurality of antibiotic disks positioned on the plate in a medium. An inhibition zone surrounds each of the antibiotic disks after a prescribed incubation period. The drug diffusion sample is illuminated, and an image of the drug diffusion sample is acquired with a video camera. The image is analyzed by determining the locations of the antibiotic disks, determining the average brightness and the brightness variance of the image in a region surrounding each of the antibiotic disks, and estimating the radius of the inhibition zone surrounding each of the antibiotic disks from the average brightness and the brightness variance. The radius of the inhibition zone is indicative of drug effectiveness.

  • Patent number: 5580784
    Abstract: An apparatus utilizing chemical sensors to determine whether a particular sample vial is evidencing bacterial growth includes directing radiation sources having closely spaced wavelengths into the sample vial. Emissions from the chemical sensor due to the two spectrally spaced radiation sources are monitored, and a ratio of their differences and sums is calculated. The inventive ratio eliminates station-to-station variation between the radiation sources or detectors, and also any lot-to-lot variations in the sensor materials. An absolute indication of the conditions within the sample vial may thus be taken eliminating the prior art, station-to-station variations and lot-to-lot variations in the sensors resulted in varying readings for positive and negative samples. Thus, any one reading could not be utilized to make a prediction of whether a particular sample is a positive or a negative.

  • Patent number: 5567598
    Abstract: This invention presents methods for detection and evaluation of metabolic activity of microorganisms based upon their ability to consume dissolved oxygen. The methods utilize a fluorescence detection system which makes use of the sensitivity of the fluorescent emission of certain compounds to the presence of oxygen, which quenches (diminishes) the compound's fluorescent emission in a concentration dependent manner. Respiring microorganisms will affect the oxygen concentration of a liquid medium in which they are immersed. Thus, this invention provides a convenient system to gather information on the presence, identification and metabolic activity of microorganisms by determining their effect on the oxygen concentration of the media in which they are present.

  • Patent number: 5560951
    Abstract: A method of pretreating citrus fruit for facilitating peeling utilizes water infusion without enzymes for loosening the peel from the underlying segments. The infusion may be accomplished with the use of a pressure or a vacuum apparatus. A further embodiments, which may be used in the home, consists of cutting a pair of opposed holes in the peel and forcing water into one of the holes until it emerges from the other hole. Both embodiments serve to separate the peel from the segments, making the fruit easier to peel.

  • Patent number: 5558899
    Abstract: A method for the preparation of polysaccharide derivatives comprises reacting at least a saccharide, such as glucose, maltose or glucose syrup, a "food grade" polycarboxylic acid, such as citric acid, or inorganic acid, such as phosphoric acid, which also acts as catalyst, and optionally a polyol, such as serbitol, under the influence of electromagnetic waves to give a reaction product at a temperature of 140.degree.-300 .degree.
