phosphodiesterase 5 enzyme use in industry of yeast extracts and pharmaceutical

    5`-Phosphodiesterase enzyme is an enzyme-based preparation derived from the Penicillium citrinum strain through a series of processes including strain cultivation, submerged liquid fermentation, extraction, multi-stage filtration, and refinement. This nuclease is widely applied in the manufacturing of nucleotides, as well as flavor-enhanced food products such as yeast extracts.

1. Enzyme preparations are bioactive substances that are susceptible to the inhibitory and destructive effects of heavy metal ions (Fe3+, Cu2+, Hg+, Pb+, etc.) and oxidants. Contact with them should be avoided during use and storage;

2. For people who are easily sensitive, it may cause hypersensitivity reactions; Close contact or slight inhalation may irritate the skin, eyes, and mucosal tissues; During the use of enzyme products, it is recommended to wear protective equipment such as masks and eye masks.

3. Moisture proof, light proof, sealed and stored at low temperature (0-10 ° C) for 18 months. Enzymes experience a certain loss of enzyme activity during storage, with 5-10% loss of enzyme activity at 10 ° C for 6 months and 10-15% loss of enzyme activity at room temperature for 6 months.

4. Extending the storage period or being affected by harsh storage conditions such as high temperature and humidity can lead to an increase in usage.
