Anaerobic kwayoyin. Rayuwa ba tare da tsarki oxygen

Anaerobic kwayoyin zai iya ci gaba da in babu free oxygen a cikin yanayi. Tare da wasu kwayoyin ciwon irin na musamman da dukiya, suna da wani aji na anaerobes. Akwai iri biyu anaerobes. Kamar yadda facultative da obligate anaerobic kwayoyin za a iya samu a kusan duk samfurori da pathologic abu Properties, su suna tare da daban-daban pyo-kumburi cututtuka iya zama opportunistic kuma ko da lokaci-lokaci pathogenic.

Anaerobic kwayoyin na ga tilas wanzu da kuma ninka a oxygen, da kuma oxygen-free muhalli. A mafi pronounced wakilan wannan aji ne E. coli, Shigella, staphylococcus, Yersinia, streptococci da sauran kwayoyin.

Obligate kwayoyin ba zai iya tsira a gaban free oxygen da kuma mutuwa daga ta effects. Na farko da kungiyar a cikin wannan aji aka wakilta anaerobes spore kafa kwayoyin ko clostridia, da kuma na biyu kwayoyin ba nunawa spores (ba clostridial anaerobes). Clostridia sukan causative jamiái na anaerobic cututtuka na wannan sunan. An misali iya zama clostridial rauni cututtuka, botulism, tetanus. Non-clostridial anaerobes ne gram-tabbatacce kuma gram-korau kwayoyin. Su sanda-dimbin yawa ko siffar zobe siffar, domin tabbatar da ku sadu a cikin adabi da sunan da haske wakilan: Bacteroides, veyllonelly, fuzobakterii, peptokokki, propionibacteria, peptostreptokokki, eubacteria, da sauransu.

Non-clostridial kwayoyin cuta, da girma da wani ɓangare na al'ada microflora a cikin mutane da kuma dabbobi. Su kuma iya shiga a cikin ci gaban da kumburi tafiyar matakai. Wadannan sun hada da peritonitis, ciwon huhu, huhu ƙurji da kwakwalwa, empyema, sepsis, cellulitis maxillofacial yankin, otitis kafofin watsa labarai, da dai sauransu Domin da girma daga cututtuka, wanda sa ba clostridial anaerobic kwayoyin type, halayyar nuna da kaddarorin na ciki .. Da suka ci gaba, yafi saboda ƙananan juriya da kwayoyin, wanda zai iya haifar da daga rauni, sanyaya, tiyata, cuta na rigakafi da tsarin.

Domin bayani game da wani Hanyar for rike anaerobic na rayuwa wajibi ne a fahimci ainihin sunadaran da wanda akwai aerobic da anaerobic numfasawa.

Aerobic numfasawa ne hadawan abu da iskar shaka tsari dangane da yin amfani da oxygen. Karsh take kaiwa zuwa tsakiyan nonon na substrate ba tare da wata saura, sakamakon da aka shaded matalauta makamashi wakilan inorganics. A sakamakon haka ne mai iko da makamashi fitarwa. Kamar yadda mafi muhimmanci substrates for numfasawa yi carbohydrates amma kuma sunadaran da fats za a iya cinye a kan aiwatar da aerobic numfasawa.

Yana yayi dace da biyu-mataki kwarara. A farko anoxic aiwatar daukan sanya progressively substrate tsakiyan nonon don saki da hydrogen atoms dauri ga coenzymes. Na biyu, da oxygen mataki, tare da kara tsakiyan nonon na da hydrogen atoms daga substrate for numfasawa da ta sauka a hankali hadawan abu da iskar shaka.

Anaerobic numfasawa amfani anaerobic kwayoyin. Suna amfani da hadawan abu da iskar shaka na numfashi substrate ba kwayoyin oxygen, da kuma wani jerin oxygenated mahadi. Wadannan iya zama salts na sulfuric, nitric, carbonic acid. A lokacin anaerobic numfasawa suka zama rage yawan mahadi.

Anaerobic kwayoyin ɗauke da numfashin matsayin karshe electron Mai karɓar, oxygen da ba a amfani, da kuma inorganic abu. Kamar yadda na ga wani aji akwai da dama iri anaerobic numfasawa: numfasawa da nitrification nitrate, sulfate da sulfur numfashi, "baƙin ƙarfe" da numfashi, da numfashin mai carbonate, fumarate numfasawa.
