PCT No. PCT/DK92/00143 Sec. 371 Date Dec. 15, 1993 Sec. 102(e) Date Dec. 15, 1993 PCT Filed May 1, 1992 PCT Pub. No. WO92/19728 PCT Pub. Date Nov. 12, 1992The 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 DEG C.; and (d) retains at least 80% of the maximal activity throughout the temperature range of 20 DEG -60 DEG C. The present invention relates to rhamnogalacturonases derived from a stain 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 DEG C.; and (d) retains at least 80% of the maximal activity throughout the temperature range of 5 DEG -50 DEG C.
