Sarufa kutenderera

Nesarufa ikaonekwa panyika somugumisiro kuputika basa muchimiro yeimwe, mukuwedzera kune izvozvo, mvura rinewo rehydrogen sulphide mune dzimwe zvinyorwa. Kutenderera Sarufa kunoratidzwa zvoutachiona pezvakaitwa izvo zvinokonzerwa zvigare zviri kuora zvinomera nemhuka residues. Pamusoro manyowa kwemapurotini ine amino acids dzine sarufa (cysteine, cystine, methionine), uye manyowa kuti chirimwa zvinokosha anonhuwirira vakaumba rehydrogen sulfide uye mercaptan. Rehydrogen sulfide iri kusunungurwa rutapudzo kuti munyu pamusoro sulfurous acid, sulfuric asidhi uye acids sernovatistoy nechokuita sulfate-yokuderedza utachiona uye kubatanidzwawo mune sarufa yatinofema.

Kutaura zvazviri, hydrogen sulfide haisi kunyura miti, uye maererano, uye mhuka. Rehydrogen sulfide oxidizes chaiyo sarufa utachiona, zvichiguma nokuumbwa sulfates izvo kwazvo yokuita zvinoitwa zvinomera. Synthesized miti sarufa tubhokisi yeimwe zvinosanganisirwawo nesarufa kutenderera zvakasikwa. Ammonifiers uye utachiona sulfate-kuderedza kubvisa pavo rehydrogen sulfide. sarufa kutenderera kunoitika, Ukuwo, tichiregeredza sarufa utachiona izvo oxidize rehydrogen sulfide.

sarufa bakitiriya boka

Sarufa utachiona vari mapoka mapoka maviri: Hauoneki uye mavara yepepuru.

Hauoneki siyana vari:

1) ose Beggiatoa - refu free- shinda. Pakati pavo pane remasangano zvose kwemabhakitiriya;

2) mamwe marudzi Thiothrix - ichiri filaments refu vari kuda pemvura zvinhu;

3) akawanda mhando utachiona chete-celled - Thiophysa.

Mabhakitiriya All - autotrophs. sarufa kutenderera kunoita kuwanda kwayo mukati muchitokisi. Under dzinongoitika ezvinhu, sarufa utachiona inowanika chete munzvimbo rehydrogen sulfide anogadzirwa nguva dzose uye pane akasununguka chokubuda okisijeni. Movement mabhakitiriya rikaitika kwemabhakitiriya ndiro. Circulation sarufa utachiona vari biosphere achisunda vachitsvaka okisijeni pamusoro rehydrogen sulfide. Rukoko Sea Black mune utachiona riri kudzika vanenge 200 m.

The oxidation rwesarufa utachiona chete reokisijeni kunoitika mumatanho maviri. Pakutanga, vanenge oxidized kuti nesarufa, riri iiswe cytoplasm masero uye rinoshandiswa sezvo imwe simba zvinhu.

Kana svikiro hakuna kukwana rehydrogen sulfide iri oxidized zvishoma nezvishoma sulfuric asidhi zvakachengetwa nesarufa. Zvinonzi neutralized uye bicarbonates Sero adzingwa muchimiro sulfate munyu.

sarufa kutenderera zvakakwana pasina kutora chikamu ruvara sarufa utachiona zvakapfumisa bakteriopurpurinom ruvara, achivapa rinoreva zvakasiyana rutsvuku, uye photosynthetic ruvara bacteriochlorophyll.

Sarufa utachiona zvakasikwa zvakapararira. Yavanogara nesarufa zvitubu, mira mvura, silt, ivhu. Sarufa utachiona vari autotrophic, nezvairehwa carbon dioxide, vachishandisa simba, iyo yakaumbwa kubudikidza oxidation mashoma nesurferi marudzi.

Kuna Hauoneki sarufa utachiona zvinosanganisira thiobacteria izvo zvose Thiobacillus thioparus, Thiobacillus thiooxidans uye nevamwe. Kunze rehydrogen sulphide nesarufa vari oxidised thio yeimwe uyewo vari autotrophs vari munyu uye mvura yakachena muvhu.

sarufa kutenderera ari pamwe ne rutapudzo urongwa, anokonzerwa nesarufa utachiona, izvo dzimwe nguva sezvingatarisirwa kusvika zvikuru hukuru. MuGungwa Dema ari kudzika 200 M rine yakawanda yakadaro rehydrogen sulfide kuti upenyu pane zvikuru anomira. With kuunganidza rehydrogen sulfide muvhu, vakazadzwa mvura, anogona kumumisa chirimwa uye mhuka upenyu.

Sulphate kuderedza utachiona vanoumba sulfuric kuporesa dzakawanda madhaka madziva pamusoro Pyatigorsk, estuaries uye pedyo Odessa Yevpatoria. Mabhakitiriya aya anotendeuka pamwe rehydrogen sulphide iri guru dema pamusoro colloidal hydrate esimbi sulfide, impregnating yl Dam. Ngura iron uyewo kunoitika pasi mhosva yavo nokuda izvo ukama mapaipi nenyere uye kudiridza.

Sarufa utachiona vanobatanidzwa mune zvipenyu kurapwa kuti wastewater , uye tiri anoratidza yakasimba kusvibiswa ivhu nemvura misha.
