b) Physical state: powder
c) Odor: normal fermentation odor
d) pH: 2. As an enzyme for catalysis of protein hydrolysis under pH2.5 - 4.0, leather softening,
this product can be used for alcohol fermentation, wool
dyeing, juice purification, feedstuffs.5 - 5.5, most in 3.0 - 3.5
e) Activity temperature: 30 - 50oC, favorable under 40 - 45oC
f) Enzymatic activity: ≥60,000 u / g
g) Calcium ion consistency: calcium ion can protect the product
h) Storage: Should be stored in a dry and cool place.
Increase dosage after shelf life. High temperature
and damp should be avoided.
i) Shelf life: 6 months under 25oC with survival rate 100%.
j) Safety: Enzyme preparations belong to protein, which may induce
sensitization and cause allergic type reactions in sensitized
individuals.
If irritation or allergic response for skin or eyes develops, consult
a doctor. Prolonged contact may cause minor irritation for skin,
eyes or nose, so any direct contact for human body should be avoided.
Neutral protease:
This product is made from Bac. subtilis NO. 1398 through fermentation and
extraction technique. The products can be used in the industry
of leather softening and depilation, plant and animal
proteolysis, silk degumming, brewing and feedstuff. It can catalyze protein to hydrolyze into low
molecular peptide and amino acid.
Packing: 20kg / carton () or 10kg / carton ()
Specifications/ physical and chemical properties:
a) Appearance: snuff color powder
b) Odor: Normal microbian fermentation
c) Solubility: easily soluble in water
d) pH: 6.5 - 7.5
e) Enzymatic Activity: 50,000 u / g, 60,000u / g, 70,000u / g
f) Activity temperature: 40 - 45oC
g) Loss on drying:≦8.0%
h) Calcium ion consistency: calcium ion can protect the product
i) Storage: Should be stored in a dry place with low temperature. Prolonged contact may cause minor irritation for skin,
eyes or nose, so any direct contact for human body should be avoided.
High temperature and damp will make the product inactively.
j) Shelf life: 6 months at 25oC, activity remain ≧85%
k) Safety: Enzyme preparations belong to protein, which may induce
sensitization and cause allergic type reactions in sensitized
individuals.
If irritation or allergic response for skin or eyes develops, consult
a doctor. This product can catalyze the hydrolysis of protein
under alkaline condition (pH 9 - l) and is mainly used in the industry of
detergent, leather depilation, silk degumming and protein hydrolysis.
Alkaline protease:
This product is made from Bac. licheniformis 2709 through cultivation and
extraction technique.
Specifications/ physical and chemical properties:
a) Color: Snuff color
b) Physical state: powder
c) Odor: Normal fermentation odor
d) pH: Stable in 9 - 12, most in 9 - 10.5
e) Enzymatic activity: 200,000 u / g, 800,000u / g
f) Activity temperature: 40 - 45oC
g) Calcium ion consistency: calcium / manganese ion can protect and active
this product; copper / mercury ion can inhibit this product.
h) Storage: Should be stored in a dry and cool place, avoid insolation and
damp.
i) Shelf life: 25oC, 6 months, survive rate ≧90%
j) Safety: Enzyme preparations belong to protein, which may induce
sensitization and cause allergic type reactions in sensitized
individuals.
If irritation or allergic response for skin or eyes develops, consult
a doctor. Prolonged contact may cause minor irritation for skin,
eyes or nose, so any direct contact for human body should be avoided.
