Application | Comment | Organism |
---|---|---|
degradation | application of KatA for elimination of H2O2 after cotton fabrics bleaching leads to less consumption of water, steam and electric power by 25%, 12% and 16.7% respectively without productivity and quality loss of cotton fabrics | Bacillus subtilis |
synthesis | a total soluble catalase activity of 78,762 U/ml with the extracellular ratio of 92.5% is achieved by fed-batch fermentation in a 10 l fermentor | Bacillus subtilis |
