Manufacture supply food grade nuclease enzyme
This product is a 5'-Phosphodiesterase preparation produced by submerged fermentation of Penicillum citrinum followed by purification, formulation and drying. Nuclease has important applications in industrial Production of 5`-nucleotide and savory product production like yeast extract.
MECHANISM
Nucleases act on (3 ', 5 ') -phosphodiester bonds of single-stranded DNA or RNA to form 5 '-nucleotides. The enzyme also breaks down the 3 '-phosphate monoester bond in a nucleotide or oligonucleotide.
APPLICATIONS
l Industrial production of 5'- nucleotides;
l Industrial production of high nucleotides extract.

Brown powder. Color may vary from batch to batch. Color intensity is not an indication of enzyme activity.
The recommended dosage is 2-5%. The dosage has to be optimized based on each application, the raw material specifications, product expectation and processing parameters. It is better to begin the test with the convenient volume.
Enzyme preparations are proteins that may induce sensitization and cause allergic type of symptoms in susceptible individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa. Any direct contact with human body should be avoided. If irritation or allergic response for skin or eyes develops, please consult a doctor.
