Tsarin sulfur

Sulfur ya bayyana a gefen ƙasa saboda sakamakon aikin volcanic a cikin nau'in mahadi, Bugu da ƙari, ruwa a wasu kafofin kuma yana dauke da hydrogen sulfide. Tsarin sulfur yana nunawa ta hanyar tafiyar da kwayoyin halittar da kwayoyin halittu ke haifarwa lokacin da lalata dabbobi da shukawa. A lokacin da aka cire sunadarin sunadarai da suka hada da amino acid, ciki har da sulfur (cysteine, cystine, methionine), da kuma nakasawa na kayan mai da makamashin mai, hydrogen sulphide da mercaptan. Hydrogen sulfide da aka saki a cikin akan rage salts na sulfurous acid, sulfuric acid da kuma acid sernovatistoy shafe sulfate-rage kwayoyin da aka ma hannu a cikin sulfur sake zagayowar.

A gaskiya ma, barnar sulhu ba ta samuwa da tsire-tsire, kuma a cewarsa, dabbobi. Rashin sulhu na hydrogen ya yi amfani da kwayoyin sulfur na musamman, wanda ya haifar da samuwar sulphate salts, wanda sau da yawa ke shayar da tsire-tsire. Kwayoyin sulfur dauke da tsire-tsire suna hada su a cikin juyin juya halin sulfur. Amoniyawa da sulfate-rage kwayoyin saki hydrogen sulphide daga gare su. Tsarin sulfur yana faruwa, a daya hannun, saboda kwayoyin sulfur, oxidizing hydrogen sulphide.

Kungiyoyi na kwayoyin sulfur

Serobacteria sun kasu kashi biyu: launin shuɗi da launin shuɗi.

Ƙananan siffofin suna wakiltar:

1) kowane nau'i na Beggiatoa suna da tsinkaye masu tsabta. Daga cikin su, mafi yawan kwayoyin halitta ana kiyaye su;

2) wasu nau'o'in Thiothrix suna da matuka masu tsada wanda ke haɗe zuwa abubuwa masu ruwa;

3) nau'in kwayoyin marasa kwayoyin halitta - Thiophysa.

Duk kwayoyin ne autotrophs. Tsarin sulfur yana taimakawa wajen tarawa cikin tantanin halitta. A cikin yanayin yanayi, kwayoyin sulfur suna samuwa ne kawai a wuraren da aka samar da sulfur hydrogen akai-akai kuma inda akwai samar da oxygen. A motsi na kwayoyin faruwa a cikin kwayoyin farantin. Tsarin sulfur a cikin kwayar halitta yana motsa kwayoyin dake bayan oxygen da kuma bayan bayanan sulfin sulhu. Layer kwayoyin cuta a cikin Black Sea yana cikin zurfin kusan 200 m.

Daidaitawar kwayoyin sulfur tare da oxygen na faruwa a cikin matakai biyu. Da farko, an hana su zuwa sulfur, wanda aka ajiye a cikin protoplasm na sel kuma an yi amfani dasu azaman kayan lantarki.

Idan ba'a samarda sulfin sulhu a cikin matsakaici ba, sulfur da aka adana a hankali yana shayar da sulfuric acid. An rarrabe shi ta hanyar bicarbonates na salula kuma an sake shi zuwa waje a cikin nau'in sulfuric acid.

Tsarin sulfur ba zai iya yin ba tare da yaduwar kwayoyin sulfur mai ƙanshi ba, da wadatar da bacteriopurpurin pigment, yana ba su shamomi daban-daban na jan, da kuma pigmento bacteriochlorophyll.

Serobacteria a cikin yanayi suna tartsatsi. Suna zaune a cikin ruwaye na sulfur, ruwa mai laushi, laka, ƙasa. Sulfur kwayoyin ne autotrophic, assimilate carbon dioxide, yin amfani da makamashi, wanda aka kafa ta hadawan abu da iskar shaka na rage sinadarin sulfur jinsunan.

Zuwa ganyayyun kwayoyin halitta sun hada da thiobacteria, kamar Thiobacillus thioparus, Thiobacillus thiooxidans da sauransu. Bugu da ƙari da hydrogen sulfide da sulfur, sun kuma oxidize thio mahadi, su ne autotrophs, ana samuwa a cikin saline da kuma sabon ruwa ruwa, a cikin ƙasa.

Tsarin sulfur din yana tare da matakan regenerative da kwayoyin sulfur suka haifar, wanda wani lokaci a yanayi ya kai babbar girma. A cikin Black Sea a zurfin fiye da 200 m yana dauke da yawan hydrogen sulphide cewa rayuwa a can gaba daya ceases. Tare da haɗuwa da sulhunin hydrogen a cikin ƙasa, da ruwan da ruwa ya shafe, rayuwan tsire-tsire da dabbobi zasu iya dakatar da shi.

Sulfate-rage microbes samar da warkaswa sulfur laka da yawa tafkuna a kusa da Pyatigorsk, Estuaries kusa da Odessa da Evpatoria. Wadannan kwayoyin, lokacin da aka saki sulfin sulhu, juya zuwa cikin duhu na colloidal sulfur dioxide hydrate, wanda ya haifar da silt na tafki. Rushewar baƙin ƙarfe yana faruwa ne ta hanyar laifin su, wanda zai haifar da lalacewa ga tudun ruwa da isassun ruwa.

Sulfur kwayoyin ne da hannu a cikin nazarin halittu magani na ruwa mai guba , da kuma suna da alaqa da wani karfi samu daga ƙasa , kuma ruwa a cikin ƙauyuka.
