Small offices have unique needs, and thatincludes document shredding. Designed with the smaller business inmind, the Dahle 20314 is a cross-cut shredder that offers Level 3security and brings you into compliance with federal regulations. The As we all know to live in this world we have to perform some activity by which we can earn money. There are many activities by which we can earn money and meet the standards to live in this society. And from one of them is franchise. Franc
Haematococcus pluvialis cultivation is throughhaematococcus pluvialis cells reproduction and growth, thereby get the haematococcuspluvialis cells which containing astaxanthin. At present, international haematococcuspluvialis cultivation normally have the following two methods:Outdoor pond (runway pool) cultivating:simple operation, the astaxanthin in haematococcus pluvialis is low content andpoor quality. This method is generally used to cultivate Spirulina, Dunaliellaand Chlorella, but do not conducive to haematococcus pluvialis cultivate. Haematococcuspluvialis is a vulnerable algae, poor reproductive capacity, slow growth rate,can easily be polluted by other algae and microorganism in cultivating process,and at a disadvantage in competition with other algae and micro-organisms,growth was inhibited even stop. Cultivating in a large pool in the open air, sufferthe wind and rain, culture conditions beyond the control, bacteria, fungi,protozoa (such as rotifers, etc.) and other algae (cyanobacteria, etc.) willinvade and mass multiply, thereby inhibiting haematococcus pluvialis growth. Sothat it must be added antibiotics to control the bacterial production, addingpesticides to control fungi, adding insecticides to control the protozoa, addingherbicides and algaecidal to control cyanobacteria.Outdoor pipeline cultivating: cutivating haematococcuspluvialis in circulating pipeline. This method reduces the evaporation of waterand the entry of dust in the air during cultivating, but the same with thelarge pond cultivating, it can not ensure them be cultivated in a aseptic andpure environment, it will be contaminated by bacteria, fungi, protozoa andalgae, so that pipeline cultivating must also be added antibiotics,insecticides, pesticides, herbicides and so on to control pollution, which willlead to these harmful substances vestigital.The astaxanthin extract is using certaintechnology to extract the accumulated astaxanthin from haematococcus pluvialiscells, then produce the astaxanthin oil. Extraction method is mainly dividedinto two types: the solvent extraction, because of astaxanthin is a lipid (oil)insoluble substance, generally extracted by n-hexane, chloroform, petroleumether, acetone or industrial ethanol and other organic solvent extraction. Themethod is simple, low cost of extraction. but the residues of harmful organicsolvents will exist in astaxanthin, namely the residual solvent. Supercriticalliquid carbon dioxide extract, which is currently the most advanced greenextraction method. Using supercritical extraction apparatus under high pressurewith innocuous liquid carbon dioxide as solvent to extract astaxanthin, thismethod is demanded for good equipment and technology, the production cost isalso high, but the quality of the extracted astaxanthin is good, without anyresidual solvent, and maintaining the activity of astaxanthin.In summary, the natural astaxanthin qualitydepends on the technology and methods of producing natural astaxanthin. Everyaspect of production will affect the natural astaxanthins quality. The cultivationmethod determined the quality of haematococcus pluvialis. Whats more, algae powderquality and extracted method finally decide the quality of astaxanthin oil.Natural astaxanthin as the super antioxidant ingredients of cosmeticsmaterial, is processed by natural astaxanthin oil, so that each of theproduction process can affect the quality of the cosmetics.
