Embodiment 1
[0044] Take amaranth leaves with a wet weight of 100 grams, cut them into small pieces, and add 300 mL of buffer A to homogenize 6 times, each time for 10 seconds, with an interval of 30 seconds. The homogenate was filtered with gauze, the filtrate was centrifuged at 4°C and 18000g for 30min, the precipitate was dissolved in 50mL of buffer B, aliquoted, and freeze-dried for 80h to obtain the freeze-dried amaranth 13-HPL microsomal enzyme. Freeze-dried amaranth 13-HPL microsomal enzyme has good resolubility, and the enzyme activity can be completely recovered. After being stored at -20°C for 50 days, the retested enzyme activity basically remained unchanged, which can provide a stable enzyme source for separation, purification and industrial production of C6 aldehyde.
[0045] Take 10 g of freeze-dried amaranth 13-HPL microsomal enzyme powder and dissolve it in 100 mL of buffer C. Centrifuge the suspension at 30,000 g for 30 min at 4°C, and dissolve the precipitate in buffer D...
