EM (Beneficial Microorganisms) culture fluids are cultured in a clean and sanitary room with screens to prevent flies from entering the mosquitoes. There are large cylinders that can use electricity for lighting, can hold more than 50 kilograms of water, and can seal red or white plastic basins.
Materials: EM strain 1 kg, brown sugar 1.5-2.5 kg, potassium dihydrogen phosphate 92 g, a little honey, water 46 kg (if the tap water, place more than 48 hours of aeration to prevent bleaching powder harm).
Wash large cylinders and plastic buckets, put honey, potassium dihydrogen phosphate and brown sugar into large cylinders, add fresh water, shake well, and put into EM strains. Shake well. Repackaged into plastic buckets, tighten the lid to become a cultivating bucket.
Put the cultivating barrel in the sun. If it is cloudy, increase the lighting in the evening. Four or three buckets may be surrounded by squares or triangles. A 60-watt incandescent bulb is suspended in the middle and shaken twice a day. If the plastic barrel swells, it means that the air pressure is large, indicating that the microorganisms multiply quickly. The lid should be unscrewed.
Incubation temperature 22 ~ 38 °C, low temperature will extend the incubation time. After 36 hours, the addition of light was stopped and the test was: the color should be brown or tan, and if it was milky, the growth failed. The smell should be sweet and sour, and if it is not sour, it will deteriorate. PH value should be less than 3.8, if not meet the standard, the fermentation time is not enough or too little brown sugar, must continue fermentation or add brown sugar and then fermentation, and ultimately become EM culture fluid. Put the culture solution into a bottle of mineral water. Tighten the cap and shake it a few times. If a large amount of gas is produced, the culture is successful. There are sometimes suspended matter, which is normal.
EM culture fluid can not be stored in a transparent container for a long time, otherwise it will be deteriorated. If it is not used for a long time, it should be stored in a dark and semi-sealed place. The preservation period is about 1 month.
After the EM culture fluid has been successfully grown, the fermented feces can be used to produce fly maggots. The first was with manure, pig manure 80%, wheat bran 16%, EM live bacteria 4%; or pig manure 56%, chicken manure 40%, EM live bacteria culture fluid 4%.
Add the above-mentioned fecal material to the EM live bacteria culture solution (1 ton of the above-mentioned fecal material and add 5 kg) to make the moisture content at 90%, seal it with a film, ferment under sunlight, turn over the feces on the third day, and then add EM live Bacteria culture solution 3 kg, so that the PH value of 6.5 to 7 (if more than 7, add vinegar, vinegar; if less than 6.5, add lime water). They are then transported to the nursery room and piled into strips. Put some dead fish that trap flies to lay eggs. Other breeding techniques are the same.
Polysaccharides are polymeric carbohydrate molecules composed of long chains of monosaccharide units bound together by glycosidic linkages, and on hydrolysis give the constituent monosaccharides or oligosaccharides. They range in structure from linear to highly branched. Examples include storage polysaccharides such as starch and glycogen, and structural polysaccharides such as cellulose and chitin.
Polysaccharides are often quite heterogeneous, containing slight modifications of the repeating unit. Depending on the structure, these macromolecules can have distinct properties from their monosaccharide building blocks. They may be amorphous or even insoluble in water. When all the monosaccharides in a polysaccharide are the same type, the polysaccharide is called a homopolysaccharide or homoglycan, but when more than one type of monosaccharide is present they are called heteropolysaccharides or heteroglycans.
Natural saccharides are generally of simple carbohydrates called monosaccharides with general formula (CH2O)n where n is three or more. Examples of monosaccharides are glucose, fructose, and glyceraldehyde. Polysaccharides, meanwhile, have a general formula of Cx(H2O)y where x is usually a large number between 200 and 2500. When the repeating units in the polymer backbone are six-carbon monosaccharides, as is often the case, the general formula simplifies to (C6H10O5)n, where typically 40≤n≤3000.
As a rule of thumb, polysaccharides contain more than ten monosaccharide units, whereas oligosaccharides contain three to ten monosaccharide units; but the precise cutoff varies somewhat according to convention. Polysaccharides are an important class of biological polymers. Their function in living organisms is usually either structure- or storage-related. Starch (a polymer of glucose) is used as a storage polysaccharide in plants, being found in the form of both amylose and the branched amylopectin. In animals, the structurally similar glucose polymer is the more densely branched glycogen, sometimes called "animal starch". Glycogen's properties allow it to be metabolized more quickly, which suits the active lives of moving animals.
Cellulose and chitin are examples of structural polysaccharides. Cellulose is used in the cell walls of plants and other organisms, and is said to be the most abundant organic molecule on Earth.It has many uses such as a significant role in the paper and textile industries, and is used as a feedstock for the production of rayon (via the viscose process), cellulose acetate, celluloid, and nitrocellulose. Chitin has a similar structure, but has nitrogen-containing side branches, increasing its strength. It is found in arthropod exoskeletons and in the cell walls of some fungi. It also has multiple uses, including surgical threads. Polysaccharides also include callose or laminarin, chrysolaminarin, xylan, arabinoxylan, mannan, fucoidan and galactomannan.
