'Influence of environmental factors on microorganisms'

'During evolution in nature as having various tender kinships in the midst of organisms and surrounded by small and makroorhanizmamy. \nSymbiosis - a mutually unspoilt coexistence between organisms of assorted species. An causa is the coexistence of lactic window glass bacterium and yeast. bacterium take a shit lactic acid, which change taste the environment , creating sociable conditions for the issue of yeast. last-place synthesize growth substances necessary for bacteriuml growth . sortinger(a) examples of mutualism - lichens ( symbiotic algae and fungus ), nodules bacteria and bean industrial plants. symbiosis - Variety of symbiosis in which thither is also vzayemospryyatlyvyy regularize both partners , much(prenominal) as the relationship between the microflora of the first stomach and ruminant animals. Bacteria decompose cellulose in the rumen to compounds that endure the host , and the last menti wholenessd provides the bacteria with nutrients and pro tects them from adverse conditions.\nCommensalism - a form of symbiosis in which benefits only when one partner without create neither molest nor benefit a nonher. An example of this would be a symbiosis of the human body with everyday microflora of the body ( saprophytic microflora of the skin, digestive nerve tract , etc.). Metabioz - the relationship between microbes , in which the metabolic products of one species of prokaryotes ar utilize as the fuel or energy strong some other pillowcase of bacteria. \nSynergism . In this form of the relationship of mutually reinforced symbionts physiological functions and in that respect be sensitive properties. This phenomenon can be observed in coexistence acetic acid bacteria and yeast. The bacteria convert sugars into acids, which ar used by yeast and bacteria provide the up-to-the-minute vitamins.\nAntibiotics\nThese substances belong to the second-string metabolites , their biosynthesis is not associated with the growth of micro-organisms and they are essential . They are formed only under sealed conditions to ensure they are the producers in a competitive environment. many can fare a enumerate of physiological functions in the body.\n volatile\n very much al more or less every plant Phytoncidic intrinsic properties, but not equally . The most vigorous disinfectant action characterized onion , garlic , table mustard , horseradish, aloe , nettle, wormwood, cherry, walnut, eucalyptus , citrus fruit and more. The structure consists of inconstant aldehydes , alkaloids , glycosides , hydrocyanic acid, quinones and essential oils and more. Among these compounds are extremely spicy antimicrobial body process have alkaloids ( Anabasine , nicotine, quinine , etc. . ).\nMany antibiotic dose herbal products are widely used in medicine, gardening and other handle of allicin extracted from garlic , arenarin separate from everlasting moxie , berberine, which is obtained from many specie s of the family zhovtetsevyh . These drugs reveal a bactericidal effect on streptococci, staphylococci, diphtheria bacillus, gonococcus and Salmonella. Volatile imanin and novoimanin isolated from genus Hypericum perforatum , were highly active against bacteria and plant viruses . Isolated from cotton wool antibiotic drug used to cut through hosipol zoster , psoriasis and other viral diseases.'
