  • Endo-.beta.-1,4-glucanase and a DNA sequence
    Patent number: 5624835
    Abstract: The molecular characteristics and a partial amino acid sequence of an endo-.beta.-1,4-glucanase obtainable from Aspergillus aculeatus are described, as well as corresponding recombinant DNA sequences, vectors, and transformed hosts. Use of the endo-.beta.-1,4-glucanase or a pectinase preparation enriched with the endo-.beta.-1,4-glucanase for degradation or modification of plant cell walls is described.

  • Method for production of an upgraded coconut product
    Patent number: 4904483
    Abstract: The method for production of an upgraded coconut product comprises the steps of: enzymatically treating an aqueous suspension of particles of coconut meat, which may be purified, with a cell wall degrading enzyme and a galactomannase, all essentially free from lipases, and separating a sludge phase. By means of this method a higher yield of directly recoverable clear coconut oil can be obtained in comparison to the yield of directly recoverably clear coconut oil produced by known methods for aqueous coconut oil extraction.
