Alkaline protease

Description:

Alkaline protease is a proteolytic enzyme from Bacillus licheniformis 2709 bred by bacterial protoplast mutagenesis. It is a kind of proteolytic enzyme obtained by deep fermentation, extraction and purification. Its main enzyme component is Bacillus licheniformis protease, which is a serine type. It can hydrolyze the peptide chain of protein molecules to generate polypeptides or amino acids, and has a strong ability to decompose proteins. It is widely used in food, medical treatment, brewing, washing, silk, leather and other industries.

Features:

1. The production process of alkaline protease adopts advanced technologies such as microfiltration, ultrafiltration membrane separation, spray drying and vacuum freeze drying. The product quality reaches the quality standard of food grade and pharmaceutical grade, and the enzyme activity range is 200,000 to 1.5 million u/ g, can be prepared according to customer requirements.

2. Alkaline protease is an alkaline protein whose catalytic site is serine, and has excellent performance at high temperature and moderate alkalinity.

Product properties: light yellow solid powder, light yellow liquid

Application areas:

1. Alkaline protease is a non-toxic and non-side effect protein. It belongs to serine endoprotease. It is used in the food industry to hydrolyze protein molecular peptide chains to generate polypeptides or amino acids, forming protein hydrolysates with unique flavors.

2. Alkaline protease has been successfully used in the detergent enzyme industry. It can be added to ordinary washing powder, concentrated washing powder and liquid detergent. It can be used in both household laundry and industrial laundry. It can effectively remove blood stains and eggs. , dairy products, or protein stains such as gravy, vegetable juice, etc., and can also be used as a medical reagent enzyme to clean biochemical instruments, etc.

3. In the field of biotechnology, alkaline protease can be used as a tool enzyme to remove proteins (including nucleases) in the process of nucleic acid purification, without degrading DNA and avoiding damage to DNA integrity.

Definition of enzyme activity:

Ultraviolet spectrophotometry: under the measurement conditions (40±0.2℃; PH value 10.5), when the trichloroacetic acid soluble matter released by hydrolysis of casein per minute has an absorbance at 275nm wavelength equivalent to that of 1 μg of tyrosine, the The required amount of enzyme is an activity unit, expressed in u/g.

Conditions of Use:

Optimum temperature: 50℃

Optimum pH: 8.0

store:

It is recommended to store in a cool and dry environment away from light;

Long-term storage or unfavorable storage conditions will reduce the enzyme activity to varying degrees; if the temperature and humidity are too high, it is necessary to appropriately increase the usage amount during use.

Safety:

Alkaline protease is a pure natural enzyme preparation, which is a protein. The food that eats the enzyme preparation is beneficial to the human body just like eating the food containing protein.

For some sensitive people, such as direct ingestion of highly concentrated enzyme powder or droplets, it may cause allergies, and prolonged contact may irritate the skin, eyes and mucous membranes. It is recommended to wear protective equipment such as masks and goggles during the operation. The remaining or spilled enzyme powder should be disposed of in time. For a large amount of enzyme powder spilled, it should be gently swept back to the container, and a small amount should be vacuumed or soaked with water for cleaning. 

Alkaline protease is a biologically active substance that is easily inhibited and destroyed by heavy metal ions (Fe3+, Cu2+, Hg+, Pb+, etc.) and oxidants, and should be avoided during storage or use.
