Bio-Scouring Enzyme is developed for bioscouring process
of knitted natural cellulosic fibers. Bio-scouring is an enzymatic process that providing a milder
and gentler alternative method to traditional scouring. Coenzyme SPA-5 is liquid and alkaline pectinase
preparation. It is specially developed for bioscouring process of knitted
natural cellulosic fibers such as cotton, linen, hemp and blend. It removes
pectin and other impurities from cotton fibers without any degradation of the
cellulose, soften and eliminate cotton seed to optimize dyeing performance.
Coenzyme SPA-5 is a perfect substitution to the
traditional process of dyeing and finishing. It can replace the caustic soda,
bleaching stabilizer and other harsh chemicals, and Simplify the production
process, effectively shorten the processing hours. Decrease the TDS.COD.BOD
index in waste water.
Benefits:
This product should be stored in a cool and dry place in sealed container, avoiding insolation, high temperature and damp. The product has been formulated for optimal stability. Extended storage or adverse conditions such as higher temperature or higher humidity may lead to a higher dosage requirement.
Enzyme preparations belong to protein, which may induce
sensitization and cause anaphylaxis in sensitized individuals. Long-term
exposure may cause minor irritation for skin, eyes or nasal mucosa, so any
direct contiguity with human body should be avoided. If irritation or allergic
response for skin or eyes develops, consult a doctor.

1, the choice of pro-shellfish
Select healthy 1 to 2 years old individuals into a healthy shellfish, complete with shells, double-shelled nature, closed strong, sharp shell edge, good plump as a pro-shellfish.
2. Artificial anatomy and insemination
At present, fertilized eggs are mostly obtained by artificial anatomy and insemination. The number of male and female progenitors is artificially inseminated at a ratio of (50-100):1. The mature female software department has a slightly yellowish appearance, and the males are milky white and can be easily identified by the naked eye. The specific approach is: first squeeze the egg into a bucket filled with about 180 liters of seawater. After the number of eggs reaches a certain concentration, squeeze into the appropriate amount of semen, and then stir it thoroughly. At the same time, remove the foam produced on the bucket surface. Set for 10 minutes, filter by 200 mesh sieve bag and pour into the hatching pond to hatch.
The hatching density is generally 150-250 kg for each 10 tons of water in the female body and the hatching density is controlled within 30 eggs/ml.
3, larvae cultivation
Fertilized eggs develop into "D" shaped larvae after about 1 day (water temperature is around 23°C), and larvae can be selected and larvae cultured in different pools.
Feeds Cultured Pacific oysters have bait species such as Phaeodactylum tricornutum, Nitzschia clostridium, Chaetoceros, Isochrysis galbana, Platymonas, cloud-microalgae, etc. At present, they mainly cultivate cloud microalgae, Nisslna spp., and horns. The three kinds of algae, algae, and Nitzschia closterium and Chaetoceros sp. We are generally cultivated directly from sea water. We are collectively referred to as diatoms in the sea area.
(1) Culture of cloud microalgae: Cloud microalgae is an unnamed green algae. Its individual is small, only 1.6-2.6 micron. It has wide adaptability and is easy to cultivate. It can grow and reproduce all year round. It is a Pacific oyster nursery. The main bait variety. The microalgae inoculation density is 3.5 to 4 million/ml. After inoculation, with the increase in the number of algae cells, it is necessary to add new water in time to prevent algae from aging. Normally, the amount of water added every morning is 1/3 to 1/2, and after adding water, the density should be about 4 million per milliliter. The speed of reproduction is too fast. At noon, a small amount of water is added to control the density of no more than 7 million/ml to prevent aging. The fertilization amount of the cloud microalgae was determined by the fertilization method every other day. Each time, total nitrogen was used to apply nitrogen (N) 5 g/m 3, phosphorus (P) 0.5 g/m 3, and iron (Fe) 0.025 g/m 3.
(2) Culture of diatoms in the sea area: diatoms are directly collected from the sea water and fertilized with a 300-mesh sieve bag. In the Luoyuan Bay area where the water temperature is below 25°C, the algae cultivated from seawater are mainly Nitzschia closterium (commonly known as small diatoms). When the water temperature is above 25°C, the algae cultivated from seawater are mainly Chaetoceros. Diatom inoculation density in the sea area is 152,000-200,000/ml. Diatoms in the sea area must be continuously added with water due to their rapid growth. In order to prevent their aging, the density should be controlled within 400,000/ml, and the pool must be poured every other day in order to achieve The purpose of continuous culture. The amount of diatoms applied in the sea area was calculated every morning in the total body of water. Nitrogen application rate was 3 g/m3, phosphorus 0.3 g/m3, iron 0.015 g/m3, and silicon (Si) 0.3 g/m3.
2. The larvae cultivate density "D"-shaped larvae, and the larval density is preferably 4-5/ml, the initial larvae at the top of the shell is 2-3/ml, and the eye larvae period is 1/ml.
3. Feeding and feeding currently use larvae mainly for cloud microalgae and diatoms in the sea.
As the larvae's growth bait amount should be increased, the larvae's gastrointestinal fullness must be observed after feeding. Generally, most of the larvae are full after 1 hour of feeding. Otherwise, the amount of bait must be adjusted, and the seedlings must be observed. The color of the pool is generally changed at high speed after casting and water quality.
