  • Patent number: 7938981
    Abstract: A composition for deicing or for the preparation of a heat transfer fluid is provided. The composition comprises a mixture of at least two carboxylic acid salts having a t/c ratio of 2 or lower, including a dicarboxylic salt and a monocarboxylic salt, said dicarboxylic salt being present in the mixture in an amount of at least 50 wt % of the weight of the mixture, on a dry basis. More particularly, said mixture is including a succinate and a formate, wherein the succinate is in an amount of at least 50 wt %, on a dry basis. Also provided is a method for deicing a surface or preventing the accumulation of ice, snow or a mixture thereof on a surface, comprising a step of applying on a surface covered by ice, snow or a mixture thereof, or susceptible of being covered by ice, snow or a mixture thereof, the above composition. The composition is also useful for the preparation of a heat transfer fluid coolant to be used in a heat transfer system comprising a heat transfer fluid provided with a cooling system.

  • Patent number: 5660612
    Abstract: The present invention provides a process of decontaminating soil and/or sediments containing DDT type contaminants by converting these contaminants into harmless materials thereby decontaminating the soil to whatever extent desired, either partial decontamiation or complete remediation. The process comprises treating solid and/or sediment which contains populations of viable anaerobic and aerobic microbes capable of transforming DDT type contaminants into harmless materials and being viable under both anaerobic and aerobic conditions.

  • Patent number: 5371011
    Abstract: Anti-fungal and anti-microbial bacterial strains of Serratia are used in the preparation and preservation of animal feedstuffs made from forage. Bacterial strains of Serratia rubidaea are particularly useful for such purposes, and permit hay to be baled at higher moisture content. Mixtures of this strain with another anti-fungal bacterial, such as Bacillus subtilis, and/or lactic acid-producing bacterial strains, such as strains of Lactobacillus, Streptococcus, Enterococcus, Lactococcus and Pediococcus are used in the preparation and preservation of silage.

  • Patent number: 5116746
    Abstract: A method of treating lignocellulosic material with a cellulase-free endo-xylanase for delignification, brightening and viscosity improvement. The endo-xylanase is obtained by the overexpression of the xylanase gene using a cellulase-negative recombinant microorganism of the genus Streptomyces. The recombinant microorganism is produced in a homologous cloning system in which the xylanase gene is inserted into a vector plasmid to provide the hybrid plasmid that is introduced into a host cellulase-negative mutant strain and said xylanase gene, said vector plasmid and said host mutant strain are obtained from microorganisms of the genus Streptomyces.
