Definitions

  • This invention relates to novel detergent compositions comprising fungal mannanase enzymes.
  • the detergent compositions comprising fungal mannanases are useful in laundry and cleaning applications wherein degradation or modification of mannan is desired.
  • the invention also relates to the use of said detergent compositions in laundry and cleaning applications as well as a method for degrading mannan.
  • Mannans are mannose containing polysaccharides found in various plants. Mannans are poorly soluble in an aqueous environment and their physicochemical properties give rise to viscous dispersions. Additionally, mannans have high water- binding capacity. All of these characteristics cause problems in several industries including brewing, baking, animal nutrition, and laundry and cleaning applications.
  • ß-mannans In plant based diets different ß-mannans are present and depending on their amounts and properties they can compromise nutrient digestion, microbial colonisation and growth performance. Enzymatic degradation of mannans reduces digesta viscosity of high water soluble mannans and leads to production of manno-oligosaccharides that may form water-insoluble linear mannans present in leguminoseae. Mannanase increases average daily gain, feed efficiency, weight uniformity and livability in all monogastric animals.
  • mannan is a contributing factor to viscosity of gut contents and it thereby adversely affects the feed digestibility and animal growth rate.
  • mannan represents a substantial component of fiber intake and a more complete digestion of mannan would facilitate higher feed conversion efficiencies.

  • the pH profiles of purified mannanases were determined using the beta-mannazyme tablet assay Azurine-crosslinked carob galactomannan (T-MNZ 11/14) from Megazyme with minor modifications to suggested protocol.
  • the linearity of the assay was checked with each purified enzymes.
  • the assay was performed in 40 mM Britton-Robinson buffer adjusted to pH values between 4 and 11.
  • the enzyme solution was diluted into the assay buffer and 500 ⁇ l of enzyme solution was equilibrated at 50°C water bath for 5 min before adding one substrate tablet. After 10 minutes, the reaction was stopped by adding 10 ml 2% Tris pH 12.
  • the reaction tubes were left at room temperature for 5 min, stirred and the liquid filtered through a Whatman No.1 paper filter.
  • Relative activity (%) of mannanase is calculated by dividing mannanase activity of a sample by the mannanase activity of a reference sample.
  • the reference sample is a sample at the optimal pH.
  • the reference sample is a sample at the optimal temperature.
  • the temperature optimum of purifed mannanases was determined using the beta-mannazyme tablet assay Azurine-crosslinked carob galactomannan (T-MNZ 11/14) from Megazyme with minor modifications to suggested protocol.
  • the assay was performed at temperatures varying between 30-90°C for 10 minutes in 40 mM Britton-Robinson buffer pH7. Enzyme activity was reported as relative activity where the activity at temperature optimum was set to 100%.

  • Mannanase activity was measured as the release of reducing sugars from galactomannan (0.3 w/w-%) at 50°C and pH 7.0 using 5 min reaction time. The amount of released reducing carbohydrates was determined spectrophotometrically using dinitrosalicylic acid. Substrate (0,3 w/w-%) used in the assay was prepared as follows: 0.6 g of locust bean gum (Sigma G-0753) was blended in 50 mM sodium citrate buffer pH 7 (or citrate phosphate buffer pH 7) at about 80 °C using a heating magnetic stirrer and heated up to boiling point.
  • the solution was cooled and let to dissolve overnight in a cold room (2 - 8 °C) with continuous stirring after which insoluble residues were removed by centrifugation. After that solution was filled up to 200 ml volume with the buffer. Substrate was stored as frozen and melted by heating in a boiling water bath to about 80 °C, cooled to room temperature and mixed carefully before use.
  • DNS reagent used in the assay was prepared by dissolving 50 g of 3.5- dinitrosalisylic acid (Sigma D-550) in about 4 liter of water. With continuous magnetic stirring 80.0 g of NaOH was gradually added and let to dissolve. An amount of 1500 g of Rochelle Salt (K-Na-tartrate, Merck 8087) was added in small portions with continuous stirring.
  • the reaction was started by adding 1.8 ml of substrate solution to two test tubes and let to equilibrate at 50 °C for 5 minutes, after which 200 ⁇ l of suitably diluted enzyme solution was added to one of the tubes, mixed well with vortex mixer and incubated exactly for 5 min at 50 °C. Enzyme blanks didn't need to be equilibrated or incubated.
  • sample solution 200 ⁇ l was added to the enzyme blank tubes. Both tubes were placed in a boiling water bath. After boiling for exactly 5 minutes, the tubes were placed in a cooling water bath and allowed to cool to room temperature. The absorbance of sample was measured against the enzyme blank at 540 nm and activity was read from the calibration curve and multiplied by the dilution factor. A suitable diluted sample yielded an absorbance difference of 0.15 - 0.4. Standard curve was prepared from 20 mM mannose stock solution by dissolving 360 mg of mannose (SigmaM-6020, stored in a desiccator) to 100 ml of assay buffer and diluted to solutions containing 3, 6, 10 and 14 ⁇ mol/ml of mannose.
