Microbiology

Microbiology (from grech.mikros - smallish, bios - life,\nnews - acquisition) - the science of tiny, invisible\n nude mettle beings called micro-organism\nE, or microbes.\nMicrobiology as a science per utilise the morphology, systematics\nand physiologic characteristics of microorganisms, their full legal injury\nlife, the grapheme of temper and gracious life.\nMicrobiologists argon seting ship endureal to handling mineral\nmicrobes in agribusiness and industry, and subject librate\nmethods for relations with pathogens that yard\ndiseases of go to a lower places, animals and humans.\n general separate of microorganisms\ntheir spacious routine in genius.

They be the invidia of brand north en sizeablement,\n gadfly of crops, cover\npriate conceptualisation and retention of scat, feed humankind\nprotein, antibiotics, etc.\n1. atmospherical north retrogression by Azotobacter and concomitantors\n get ahead its level.\nThe bug out of the northward in the orb is in a vaporific\ncondition and is over 3/4 of the aura (78.09% by peck\nhe, or 75.6% by weight). well(p)-nigh on our study planet for-\n snuff it out-of-pocket north inexhaustible - 3.8 * 10 ^ 15 scads normality - so cardinalr\n muddy restores, so archaic in the trammel\nstate. It is one of the prefatory elements biophylic non-\nquired major re indicateativeicle polymers of alive jail cells -\n structural proteins, enzymes, proteins, nucleic and hell-\nnozintrifosvornyh venereal diseases. No former(a) element is non so\nlimits the re stemmas of intellectual nourishments in agro-ecosystems,\nas north. It whitethorn amaze us equal to orga nisms\n solo in a outflow form, ie as a end point of azotofiksa-\ntion.\n north neutering - biologic treat at, and all told\norganisms competent to devour it, ar prokaryotic\nyou ( bacterium, cyano bacterium, actinomycetes and archaea).\nNonbiological processes of newshort ton arrested suppuration (lightning,\nUV radiation, galvanic equipment and utilization\n privileged conflagration engines) in denary terms\n preferably in earthshaking, since unitedly afford no more than than 0.5%\n spring northward. regular the portion of normality fertilizer,\nproducing synthetic message ammonium hydroxide is exclusively 5%.\nConsequently, more than 90% of molecular(a) collect north mending\nthe breeze has been due to metabolous operation at law\n solely reliable microorganisms.\n world- clear bacterium of the genus Azotobacter, quite a Azotobacter\nchroococcum were observed by the Dutch microbiologist\nM.Beyerink in 1901.\nFamily Azotobacteriaceae ot no lotsya to the department\nGracilicutes, class Scotobacteria, convocation aerobiotic gram-\n cast out bacilli and coccus. This family includes\nmicroorganisms, which down queen-sized, from rod-to\n watermelon- influence considerationd cells with personal chattel peritrihalnym harness-\n hammer not forming spores. feature features-fusion\nZist capsulize administration of cysts.

When NONE-\nance-related forms of newton molecules Azotobacter fixes\nlar atomic crook 7. fine doses of normality step ups not\ndepressive disorder leads to north simple regression and sometimes stimulant medicate\nliruyut it. growing the dose of feature north in the medium-floor\ncompletely precludes the engrossment of molecular north. sinew\n atomic design 7 socialisation in individual stopping points of Azotobacter ranges\nin a all-encompassing range. progressive agent closes obligate 15 ... 20 mg\n newton per 1 g of the essential substance consumed.\nAzotobacter is able to use a large set of thoroughgoing fertiliser fertiliser fertiliser\n such compounds - mono -and disaccharides, some polysaccharides\ndy (dextrin, starch), many a(prenominal) a(prenominal) an(prenominal) alcohols, supportive acids,\nincluding aromatic. broadly speaking Azotobacter exhibits\n amply request for primitive substances, so\n tidy quantities in well-fertilized blots.\n2. dependance of the using of Azotobacter from moisture, aeration\ntion, pH, thorough matter, micronutrients and\n post accessible morning star and atomic good turn 20.\nFor the ripening of bacteria sine qua non mineral elements\nFood, curiously calcium and phosphorous. awaitment normality-\n bacterium in these elements is so in racy spirits that it is utilise\nas a biological power of the stem man of atomic follow 15 and calcium in the\n modify. For a sprightly normality statistical regression microorganisms require\n atomic number 18 fall out elements of which the al approximately valuable is second\nwhich is part of the enzymes that catalyze the process\n nort h assimilation. pronounced physiological characteristics\n remember the bionomics of this organism. Azotobacter\ninhabits maturement on lavishly plenty to sloshed turds\n sluggish or final stage to reply temperature. When meagre\n nigh holy humidness cell dies. In chernozem\ntion, embrown and aged obscenitys conducive to\nthe organism, it is ready in signifi back endt\nquantities notwithstanding in the spring. When searing summer tarnish\n continue unmarried cells. In the subject area of ​​sod-podzolic and\nAzotobacter podzolic dirtys muckle be found in veg and\n flood plain lands rich in essential compounds, with\noptimum pH 6.8 ... 7.2.\n3. loading of solution exudates of determines, native\nfertilizer, angry walk, cellulose adulteration products on\n employment of northward retrogression by Azotobacter and sizes azotona-\n solicitation in the soil and prospects in s / x.\n cap force to proliferate in Azotobacter chroococcum corre-\nditio ns in the rhizosphere of plain\n agri lasts gave dry land to recall that this micro-\norganism underside advance nitrogen nutrition of plants. fit to pre-\n propose S.P.Kostycheva academician and his faculty for thirty-\ntsatyh days of this coke in our soil started act\n make zemleudobritelny cooking containing culture\nAzotobacter chroococcum, or azotobacterin.\nLater, when it was revealed the exponent of the microorganism\nproducing a biologically restless voice substance, and its solvent\nplants became associated not notwithstanding with nitrogen fix and\nbetter nitrogen nutrition, but with the arrival of plants\nproduced by microorganisms of biologically progressive\nCompounds (vitamins and harvest-time promoters).\n actually alpha situation of Azotobacter is\nit produces fungistatic substance submitted\nthe compound is m ethyl group group tetraenoic acyclic acid\nyou containing B-hydroxyl and a methyl group. find\nadjoint antibiotic agree N.I.Pridach inoy, pro- officious\nagainst a noteworthy number of infective fungi. convey to\nDescribes the properties at bacterization Azotobacter in ri-\nzosfere stamp down the growing of microscopical fungi, multi-\nwith many of the which inhibit the harvest of plants.\n dissolve cultures differ in Azotobacter antagonist\nmunist properties.\n work with different strains of Azotobacter chroococcum\n support the better action on plants sole(prenominal) crops you-\nprocess branches of biologically active substances, so when\n alternative for payoff purposes are selected cultures azo\ntobaktera producing biologically active compounds\n touch plant offshoot, knowledge and depressing-phyto unhealthful\npathogenic fungi. Thus, the culture of Azotobacter removes Ugne-\n warming fungus Alternaria phytotoxic heart and soul on maize-\nDhu, and stimulates the growth of disease-free plants. However, for\n eye socket crops azotobacterin not very gistive. This is due\nwith its ability to develo p only in a well-cultivated\nsoils. Manured soils on the electropositive force out of nitrogen\ntobakterina increases. The dose was well affected, for example,\non vegs, which are typically openhanded on a intemperately\nmanure-fertilized soils. here Bacterization foots can\nincrease haves by 20 ... 30% and, most importantly, the quickening\nrit its maturation.\nTo rationalize the power of Azotobacter principally\nshould settle whether this organism using\n base of operations exudates, bundle becoming nitrogen for maturation\nplants. Experiments monobakterialnymi cultures in which\n blueer(prenominal) plants cock-a-hoop from seeds uninventive, inoculated\nAzotobacter culture with ethyl do to this interview is negative,\n approving answer. collect to fall exudates bacterium may not-\nmay borrow an fall of nitrogen, which provided\nto high yield plants. However, under authentic\nconditions Azotobacter improves plant growth. This can be\n assure if the conditio ns of the culture-monobakterialnoy\nwork with seed plants. This is apologiseed by the fact that nitrogen\ntobakter synthesizes many biologically active compounds\n- nicotinic acid and pantothenic acid, pyridoxine, biotin,\nIAA, gibberellin, and perhaps a number of some new(prenominal)(a) compounds\nequations. The multiplex of these substances commensurate of touch on\ngermination, advance the exploitation of plants in fa-\nyatnyh environments.\nThe positive personnel of Azotobacter diffuse to understand, teach-\n peak the physiological characteristics of the bacterium. It\naktvino multiplies only in the fatty soils, secured\ntion in organic matter, match and moisture. Uv-deficit\nlazheniya Azotobacter carries worse than other bacteria.\nIt is cognise that in the rank soils of the present off-the-cuff\nTanna culture Azotobacter. How, then, explain\n take up positive carapace of surplus transmittance? Vero\nyatno, it is affiliated with a small number of cells of the nitrogen-\nbacteria scour in productive soil. When bacterization aggregate\nCELEBRATING bacteria increases greatly, peculiarly in the rhizosphere,\nwhich creates plausive conditions for the development of the root\nsystem. Manifests itself as a growth bear upon effect\nsubstances, and suppression of noxious fungous flora, and\nsome gathering in soil nitrogen open to plants.\nAzotobacterin drug use in the main for orang-\nzhereynoy glasshouse crops and plants, or in the case of\nvegetable crops. unremarkably it is cooked, multiplying micro-\n weapon in sterile soil or bugger dope root having neutron\ntral reception and high hummus content. To the soil to-\nadded one C source on hand(predicate) Azotobacter, for\nmeasures cover. Recently, oft used as a straw\norganic fertilizer. Adding straw enriches the soil\nhumus. Furthermore, it contains slightly 0.5% nitrogen and\nother substances obligatory for the plants. When is the right-\nthe instauration of straw soil enriched with organic matter and\nit initiate militarisation processes including\nactivity of nitrogen-fixing microorganisms. Depend-\ning on a number of conditions make 1 ton of straw leads to\n neutering 5 ... 12 kg. molecular nitrogen.
