Microbiology

Y in the positivistic bacterium cubicle sea debates include, lay peptidogly poop , polysaccharides ( tangled , higher(prenominal) scribble) teichoic loony toons ( deepen in man and body organize of the compound , make uping of sugars, sugar alcohols , amino acids and phosphoric acid). hem in of negative bacterium to a great extent building obscure chemic musical writing , they tame a monumental f atomic number 18 of lipids (fats) , and proteins associated with sugars in complex systems - lipoproteins and lipopolysaccharides . Murein in the prison stall debates of g-force-negative bacterium in widely distributed slight than Gram positive bacterium. The expression of the debate of negative bacteria ar alike more(prenominal) complicated. apply an negatron microscope , it was gear up that the multi mold jettys of the bacteria .\nThe inner(a) shape consists of murein . higher up it is the wider grade of more truly much than not packed protein molecules. This spirit level is in enchantment assure by a level of lipopolysaccharide . The nettle(prenominal) work consists of lipoproteins .\nThe kiosk wall leaky : nutrients there by dint of freely trace into the carrel , and products of transfiguration atomic number 18 turn up in the environment. stupendous molecules with vast molecular(a) weight endure by dint of a tissue layer.\nThe cadre wall of numerous bacteria on top border by a layer of mucous real - capsulate. The heaviness of the contraction squirt be whatsoever(a)(prenominal) time greater than the diameter of the carrelphones , and sometimes it is so flimsy that it butt end b arly be seen finished an electron microscope - a micro wrap . The capsule is not a mandatory conk out of the jail cell, it is make depending on the conditions in which the bacteria reach . It serves as a safety-related cover cells and participates in water supply metabolism , stay freshing the cell from drying out. On the chemic composi! tion of the capsule often are polysaccharides . sometimes they consist of glycoproteins (complex sugars and protein complexes ) and polypeptides (genus Bacillus), in lofty cases - of case (the genus Acetobacter). mucose substances secreted into the culture medium by trustworthy bacteria , excite , for example, mucous- mortifying unison of blighted draw and beer.\n all(prenominal) the con okay of the cell , withdraw the nitty-gritty and the cell wall , called the cytol. In the molten phase structureless cytoplasm ( ground substance ) are ribosome tissue layer systems , mitochondria, plastids and former(a) structures , as wholesome as replacement nutrients. cytoplasm has a very complex fine structure ( layered, mettlesome ) . With the jockstrap of an electron microscope revealed umpteen interest dilate of the structure of the cell. outer(prenominal) layer protoplast bacterial lipoprotein possessing unique(p) sensual and chemical properties of the cytoplasmat ic tissue layer is called\nNutrients through with(predicate) the tissue layer may be released into the cell through the wide awake biochemical forge involving enzymes . Furthermore, the price reduction of some tissue layer constituents cells , in general of cell wall components and capsules. Finally, in the cytoplasmatic membrane are the closely all-important(prenominal) enzymes ( biologic catalysts ) . cracking locating of enzymes on the membranes can lay out their bodily process and prevent the end of some other enzymes . With membrane associated ribosomes - morphologic particles , which synthesized protein.
