摘要:
The present invention relates to rhamnogalacturonases derived from a strain of Aspergillus japonicus which (a) has a pH-optimum between 6.5 and 7.0; (b) retains at least 80% of the maximal activity throughout the pH range of 5.5-12; (c) has a temperature optimum of about 40.degree. C.; and (d) retains at least 80% of the maximal activity throughout the temperature range of 20-60.degree. C. The present invention relates to rhamnogalacturonases derived from a strain of Aspergillus aculeatus which (a) has a pH-optimum of about 5.0; (b) retains at least 80% of the maximal activity throughout the pH range of 3-6.5; (c) has a temperature optimum of about 40.degree. C.; and (d) retains at least 80% of the maximal activity throughout the temperature range of 5-50.degree. C.

摘要:
An isolated and purified acetyl esterase with activity towards acetylated xylan and acetylated mannan obtained from Aspergillus aculeatus and having amino acid sequence that comprises Seq ID No 1. An enzyme can be used for the modification of plant cell wall components.
摘要:
The xylanase is characterized by several partial amino acid sequences and is immunoreactive with an antibody raised against a purified xylanase derived from Humicola insolens, DSM 1800. This xylanase preparation is practically free of cellulase xylanase and is well suited for treatment of paper pulp, as a baking agent and as an additive to fodder.
摘要:
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.
摘要:
The present invention relates to rhamnogalacturon acetyl esterases derived from Aspergillus aculeatus and DNA Sequences encoding the enzymes. The present invention also relates to the use of rhamnogalacturon acetyl esterases for degrading modified hairy region.
摘要:
An enzyme exhibiting xylanase activity, which enzyme is immunologically reactive with an antibody raised against a purified xylanase derived from Aspergillus aculeatus, CBS 101.43. The enzyme may be used for degrading plant cell wall components e.g. in the preparation of feed, in baking, in the paper and pulp industry and in connection with separation of wheat into starch and gluten.
摘要:
A partial amino acid sequence of an endo-.beta.-1,4-glucanase obtainable by means of Aspergillus aculeatus is described, and also 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.
