  • Patent number: 5652006
    Abstract: A method of processing a solid foodstuff, such as a meat portion or portion of plant foodstuff, by a heating and cooling cycle in which the environmental pressure applied to the foodstuff is controlled during heating so that, at a maximum target temperature, all parts of the body of the foodstuff are conformed to this target temperature due to flow of water, transiently in the vapour phase, from hotter regions to cooler regions. In particular, at least when the target temperature is nominally attained, the pressure is set to the saturated vapour pressure of the foodstuff at the maximum target temperature.

  • Patent number: 5641671
    Abstract: The production of an active Pseudomonas glumae lipase isolated from P. glumae PG1 (CBS 322.89) and other lipases suitable for application in detergent systems is described in homologous, but particularly in heterologous hosts, e.g. Bacillus subtilis. For the latter a "helper function" or "lipase-specific stabilization/translocation protein" is needed, for which a gene is provided which, when expressed in concert with the lipase gene, can improve the stabilization of the intermediates involved in the production and translocation/secretion of the lipase. The hosts are transformed by recombinant DNA methods and modified lipases can be made by site-directed mutation or classical mutation techniques. The lipase gene and the gene encoding the helper function can be part of one operon that can be transcribed to form a polycistronic messenger or be present as separate genes yielding two mRNA's on transcription. The production level can be further improved by optimizing the regulation sequences.

  • Patent number: 5610077
    Abstract: A process for carrying out a specific binding assay by reacting (a) a sample under assay for the possible presence of a substance being tested for, (b) a specific binding partner for the substance being tested for, immobilised on a solid support, and (c) a specific binding partner for the substance being tested for which is conjugated to a detectable marker, to thereby form a complex by reacting between whatever quantities are present of the substance being tested for in (a) with reagents (b) and (c). The marker is immobilised to the support via the substance being tested for, and is detected or assayed as an index of the quantity present in the sample (a) of any of the substance. The reaction ingredients (a), (b) and (c) are all mixed in a single step for reaction in a single reaction liquid.
