Interactions between microorganisms, micro - and Macro-organism. In the external environment microorganisms are part of biocenosis (set of plants and animals that inhabit the area uninhabited environment with more or less uniform conditions of life). nrg houston tx When a compatible nrg houston tx development in one and the same environment microbes come from other organisms (Macro-organism) and with each other in certain nrg houston tx relations. There are several types of relationships: symbiosis, commensalism, parasitism, metabioz, antagonism. nrg houston tx
Symbiosis. Compatible Development (coexistence) of two or more different organisms that usually bring them mutual benefit, they jointly developing better than each of them separately. Between the symbionts nrg houston tx is a partial exchange of waste products. In the case where symbionts completely lose their ability to exist separately, is mutually beneficial co-existence is called nrg houston tx mutualism. Examples mutualizmu is coexistence of lactic acid bacteria and yeasts beans, yogurt, and mare, cohabitation acetic acid bacteria and yeasts in the tea fungus, bacteria klubenkovyh symbiosis with leguminous plants, nitrogen-fixing microbes and tsellyulozoutvoryuyuchyh bacteria, various fungi with the roots of plants and others.
Synergism is characterized by the fact that the joint development of two or more organisms of the same group (microbial associations) their basic physiological functions are stronger than in the development of each individual. For example, the joint development of lactic acid bacteria in milk (active kyslotoutvoryuvachiv) and aromatoutvoryuyuchyh lactic streptococci faster growing acidity of milk and intensified nrg houston tx livelihoods aromatoutvoryuyuchyh streptococci, and of forming aromatics. Different types of putrefactive nrg houston tx bacteria evolved together in the product break down proteins more rapidly than some of their views.
When satellizmi one of cohabitants called predisposing parasite stimulates other fellow-members. For example, some saprophytes (yeast and sartsyny) produce amino acids and vitamins, promoting the growth of demanding to the culture media of pathogenic microbes. Azotobacter synthesizes vitamins and other biologically active substances that stimulate the growth of microbes that convert organic phosphorus into inorganic forms, which in turn positively affects the development of higher plants.
Viroheniya - a joint existence (symbiosis) nrg houston tx viruses (temperate phages) and some bacteria, yeast and simplest. Phage that penetrated into the microbial cell without causing nrg houston tx its death (lysis). Cells continue their livelihoods, being the bearer of phage. nrg houston tx
Commensalism. It is dimly expressed form of coexistence with other microbial organisms. When such relationships one organism (microbe) live by another, without giving him a significant advantage and without causing damage. Such relationships are characteristic of lactic acid bacteria, nrg houston tx yeast and other microbes that live on plants, nrg houston tx which in this case is a commensal in relation to plants. By commensal also includes the vast majority of "normal" microflora nrg houston tx of animals and humans, who are resident in the gastrointestinal tract, upper respiratory tract, skin. For example, E. coli and lactic acid bacteria during development in the large intestine obtained from microorganism all substances necessary for life, not causing him harm and even bringing some benefits that create an acidic environment in the intestine and inhibit the development of putrefactive and pathogenic bacteria.
Parasitism. Biological parasitism is a relationship between organisms where one of them (the parasite) lives at the expense of another (host) and causing him harm. An example of such a relationship between organisms is the development of bacteriophage by living nrg houston tx bacterial cells that result from this die and disintegrate. Parasitism is also observed in the relationship between pathogenic microbes and animals or plants. nrg houston tx
Metabioz. This is the kind of relationships nrg houston tx between organisms, as a result of some microbial life creates the conditions nrg houston tx for the further development of others. For example, one group of microbes accumulate in the environment his life products that are substrates for feeding a group of microbes. Thus there is a succession

of some other types of germs. An example is the relationship metabiozu
