Natural extracts are biologically active compounds or mixtures extracted from various plants and animals or microorganisms in nature. These extracts contain a wealth of chemicals, Such as alkaloids, flavonoids, saponins, polysaccharides, volatile oils, collagen, proteins, peptides, enzymes, antibodies, antibiotics, amino acids, nucleic acids, enzymes, monosaccharides, oligosaccharides, polysaccharides, glycoproteins, resins, colloids, lignin, vitamins, fats, oils, waxes, alkaloids, volatile oils, flavonoids, glycosides, phenylpropanoids, organic acids, phenols, quinones, steroids And antibiotics, etc. Natural Extracts, Chinese herb extract, plant P.E., Herb extract Xi'an Day Natural Inc. , https://www.dayextract.com
What is Natural Extracts?
Natural extracts have received attention in several fields due to their wide range of sources and potential multiple uses. They can be used in the pharmaceutical industry as ingredients in medicines or health supplements; In the cosmetic industry, as a functional or active ingredient to improve skin health; In the food industry, as an additive or flavoring agent to increase the nutritional value and taste of food; In addition, they have different applications in the fields of agriculture, environmental protection and scientific research.
Extraction methods include solvent extraction method, ultrasonic extraction method, microwave extraction method, enzyme extraction method, supercritical fluid extraction method and microwave assisted extraction method, etc. The choice of which method usually depends on the nature of the substance to be extracted and the target requirements of the final product. With the development of technology, the extraction process is continuously optimized to improve extraction efficiency, reduce environmental impact and maintain the biological activity of the extract.
Photosynthetic bacteria is a kind of high-tech biological products. The bacterial cells contain more than 60% of protein, and are rich in B vitamins, Amino Acids and growth promoting factors. They are high quality and safe nutritive feed additives. For shrimp farming can activate the shrimp immune system, enhance resistance to disease, promote metabolism, and thus increase feed remuneration. In addition, photosynthetic bacteria can also degrade and remove harmful hydrogen sulfide and phenols, amine toxicants, and absorb heavy metal ions, so that the shrimp pond water quality can be purified. When the dissolved oxygen in the water of shrimps declines, the PH value decreases, and the water quality deteriorates, 5 kg of photosynthetic bacteria liquid (concentration of 1 billion to 2 billion bacteria per milliliter) is applied at a depth of 1 meter per acre, which can make the water stable and transparent. As the pH value increases, the dissolved oxygen in the water, especially at the bottom of the shrimp pond, increases and the shrimp body vigor increases. Photosynthetic bacteria should be started before the shrimps are released, and they should be applied every 10 to 15 days until they are harvested. Photosynthetic bacteria can be mixed with clean and fine sand and spread evenly in the whole pond, or diluted with photosynthetic bacteria solution and then sprinkled in the whole pond. It is also possible to add 3% photosynthetic bacteria liquid to the shrimp feed. Photosynthetic bacteria cannot be used together with disinfectants such as quicklime and bleach. The use of photosynthetic bacteria on a continuous rainy day is not effective and should not be applied.
