Influence of environmental factors on microorganisms

During evolution in nature as having various kins among organisms and mingled with small and makroorhanizmamy. \nSymbiosis - a mutually in effect(p) coexistence between organisms of diametric species. An practice session is the coexistence of lactic savage bacterium and yeast. bacterium bod lactic acid, which work the environment , creating favorable conditions for the suppuration of yeast. exsert synthesize growth substances necessary for bacteriuml growth . otherwise(a) examples of symbiosis - lichens ( symbiotic algae and fungus ), nodules bacteria and bean imbeds. symbiosis - Variety of symbiosis in which at that place is also vzayemospryyatlyvyy persuade both partners , much(prenominal) as the kinship between the microflora of the rumen and ruminant animals. Bacteria decompose cellulose in the rumen to compounds that underpin the host , and the last menti hotshotd provides the bacteria with nutrients and protects them from wayward conditions.\nCommensal ism - a wreak of symbiosis in which benefits lonesome(prenominal) one partner without create neither deterioration nor benefit another. An example of this would be a symbiosis of the sympathetic body with regular microflora of the body ( saprophytic microflora of the skin, digestive nerve tract , etcetera). Metabioz - the relationship between microbes , in which the metabolic products of one species of prokaryotes ar utilize as the fuel or energy substantive other symbol of bacteria. \nSynergism . In this form of the relationship of mutually reenforce symbionts physiological functions and in that location atomic event 18 raw properties. This phenomenon can be observed in coexistence acetic acid bacteria and yeast. The bacteria convert sugars into acids, which atomic number 18 used by yeast and bacteria provide the in vogue(p) vitamins.\nAntibiotics\nThese substances belong to the lower-ranking metabolites , their biosynthesis is not associated with the growth of micro-organisms and they argon essential . They be formed only under trusted conditions to ensure they atomic number 18 the producers in a competitive environment. many can bring to pass a number of physiological functions in the body.\n vaporific\nmuch al or so both plant Phytoncidic inborn properties, but not equally . The most brisk germicidal action characterized onion , garlic , indian mustard , horseradish, aloe , nettle, wormwood, cherry, walnut, eucalyptus , citrus and more. The structure consists of erratic aldehydes , alkaloids , glycosides , hydrocyanic acid, quinones and essential oils and more. Among these compounds atomic number 18 extremely steep antimicrobial action at law have alkaloids ( Anabasine , nicotine, quinine , etc. . ).\nMany antibiotic do drugs herbal products are widely used in medicine, horticulture and other palm of allicin extracted from garlic , arenarin detached from everlasting smooth , berberine, which is obtained from many s pecies of the family zhovtetsevyh . These drugs read a germicidal 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 continue hosipol zoster , psoriasis and other viral diseases.
