This effect can be observed especially when the animals do not spend the cold season exclusively in the cowshed, but are kept on winter pastures. The study, carried out on a Czech farm, proved that two factors are vital for this process to take place: the amount and quality of organic material from the excrement and the strong compaction of the soil by the weight of the cattle. These changes lead to the fact that methane-producing micro-organisms from the gastro-intestinal tract of the animals can be established in the soil while, simultaneously, the process of methane oxidation is restrained.
Grass lands that are not used intensively for agriculture generally act as sink for the greenhouse gases, methane, carbon dioxide and laughing gas. However, this situation can change if intensive management of the pastures with cattle occurs. Indeed, it is known also that well-aired soils have the potential for producing methane. Hence, the scope of the study should include examination of the extent to which the over-wintering of cattle on pastures stimulates this potential, and grassland soils really becomes a methane spring.
Unlike typical summer grazing, where the animals spread out evenly, the animals on the winter pastures prefer to stay near the feed house. As a result, no vegetation was visible any more in this area, and the ground was strongly compressed. In addition, this area was marked by a very high incidence of organic matter from the excrement of the animals. In more distant areas, the consequences were far less drastic.
The intensive grazing in the areas close to the cowshed led to a clear increase of methane emissions throughout the whole winter. These showed 1,000 times more than the control areas, where no bovine animals were kept. Methane oxidation is the metabolic way that can lead to the breaking down of the methane. Interestingly, the classical process of methane oxidation, which is related to aerobic conditions, was restrained in the intensely grazed areas. According to Schloter, this is explained by the high quantities of urea in the ground. The scientists were able to show further that methane producing micro-organisms from the gastro-intestinal tract of the cattle could survive in the soil and suppress parts of the autotchtone microflora. The newcomers profited from the environmental conditions in these soil, namely the extensive organic material.
Although in summer and autumn the animals were kept on other pastures, the composition of the microflora barely changed in the strongly over-grazed areas. Indeed, the methane production rates clearly decreased during these months, because the continuous supply of organic material was absent.
In addition, we have possibly proved a very rare process in the strongly compounded areas, namely the anaerobic oxidation of methane. All in all, it can be said that just about every agricultural measure has its positive and negative consequences. What weighs more in each case, however, is a social, rather than a scientific question.
Digestive enzymes is the most extensive application of a class of enzyme in digestive enzyme catalysis, the monosaccharide sugars into fat into glycerol and fatty acids, protein into amino acids. The aquatic animal characteristics of digestive enzymes, to master the aquatic animal nutrient digestion and absorption capacity for aquatic animal breeding at the same time the process of the application of bait is of great significance.
1.1 efficiency digestive enzymes and substrate is likely to occur after the combination of deformation and twisted to geometry and electrostatic closer to the transition state structure, reduces the activation energy, the reaction rate increased dramatically.n
When the reaction of zinc ions on the need exists.
1.2 substrate specificity of an enzyme decomposition or converted into only one or a substrate, as this will ensure that the body s chemical reactions play an important role in an orderly manner. Digestive enzyme substrate specificity of roughly divided into two groups: those for structural specificity, in accordance with its strict varying degrees, can be divided into absolute specificity and relative specificity, the former only role in a substrate; In the latter role similar to the structure of a class of substances.n
The regulation of the activity of enzymes as biocatalysts is different from the non-biological catalysts an important sign that the body s metabolism of important substances regulated manner. Enzyme activity is subject to regulation and control of a variety of factors, mainly in the following methods: the regulation of enzyme concentration, hormone regulation, restrictive protein hydrolysis, and the activator inhibitor adjustments feedback regulation, variable structure adjustment modified conditioning, price sharing. For example, in fish breeding, fish epinephrine, norepinephrine, and other secretion increased role in the fat cell surface receptors, so that the activity of triglyceride fats, fatty acid formation rate increase. Through restrictive trypsinogen protein hydrolysis role in the small intestine by other proteolytic enzymes restrictive and removed a six peptides, the activation become active trypsin. If encountered its trypsin inhibitor aprotinin, its activity will drop.n
Chymotrypsin; Intestinal of invertase can be activated by sodium ions.
3.1 ph value of a certain enzyme reactions are carried out under conditions ph. Ph on the impact of digestive enzymes has two main aspects: First, direct or indirect impact on the catalytic activity of enzymes, ph enzyme active site can be changed or related group of dissociation state, thus affecting digestive enzyme substrate with the combination; Second is the impact of the stability of a certain degree of stability of the acid-base, over the scope of protein conformation will change so that digestive enzyme inactivation degeneration. Most of the studies show that the aquatic animal pepsin optimum ph values in the 2-3, in neutral and alkaline environment partial inactivation; The intestinal protease in the most optimal ph value of 6.n
Temperature temperature on the impact of digestive enzymes also are two-fold: First, temperature on the stability of enzyme protein, as the temperature increased, by gradually increased activity decreased gradually until the degeneration inactivation; Second, digestive enzymes of temperature on reaction rate effects, which may include digestive enzyme and substrate the combined impact of the greatest reaction speed, and the impact of digestive enzyme inhibitors, the activator and the integration of coenzyme. Therefore, to a certain temperature, the enzymatic reaction rate will reach the most, the temperature of which is the optimum temperature. Enzymes in 1 hour, the loss of half of the vitality of the critical temperature called the failure temperature, the temperature of failure over this fast. The enzyme reaction temperature coefficient is a characteristic of value, the temperature is 10 degrees higher when the enzyme reaction rate increase factor. This is the measure of thermal stability indicators.n
UV, such as any violent oscillations of the protein denaturation physical and chemical factors, of these factors can make change the loss of its catalytic activity. In addition, in some of the storage process, reagents needed to protect some special role.
4.1 fish basic research on digestive enzyme specificity, and other characteristics, to clarify the metabolism of aquatic animals and orderly process, and is conducive to clarify the mechanism of digestive enzymes, digestive enzymes judgment, and for the active site structure, thereby identify the types of digestive enzymes. Different types of fish species with the characteristics of digestive enzymes are different, and the purification of various digestive enzymes, and the right conditions determination, in accordance with their demonstrated by the value of the various differences can be judged not only by the determination of a few fish if it belong to the same species, but also evaluation of aquatic animal digest food capacity the size. Alareon, etc. (1995) reported that the different varieties of fish between protease activity than there has been a great difference.
4.n
Aquatic animals of different species, different diet, food composition not the same, they require exogenous enzyme digestion is not the same type and number. Many scholars reported that carnivorous fish protease and amylase concentration higher concentration lower, and herbivorous fish is just the opposite.n
Digestive enzymes based on the catalytic properties, the method used protease hydrolysis of protein solution with more trash can, through the extraction, concentration, drying, made of nitrogen loading so high, the rich variety of vitamin products.
The aquatic animal characteristics of digestive enzymes, is the understanding of the relationship between structure and function, the mechanism of the enzyme an important means; Understanding aquatic animals is an important content of digestive physiology. On the one hand, the activity of enzymes in the body reflects the level of aquatic animals in vivo physiological status; On the other hand, if the control plane in the level of enzyme activity, we can function on the activities of aquatic animals make corresponding adjustments. Therefore, the understanding of the biology of digestive enzymes for the production of practice is important guiding significance.
