Article Synopsis
- The study explores the production of cellulase using agricultural waste, specifically Molokhia stems, through the fermentation process using Aspergillus awamori MK788209.
- Statistical optimization techniques, Plackett-Burman and Central Composite Design, significantly improved cellulase yields by 2.51 and 4.86 times, respectively, and increased sugar recovery from pea peels to 338 mg reducing sugar/ml.
- The produced cellulase demonstrated high effectiveness not only in breaking down agricultural waste but also in improving the properties of cotton fabrics for textile applications.
Background: Flavonoid natural dyes have gained attention because they are nontoxic and eco-friendly. However, they do not work effectively with artificial fibers and require the use of mordants, which are considered as hazardous chemicals. Laccase enzyme catalyzes the oxidation of phenols, forming phenoxyl radicals that undergo a further polymerization process.
