BES, Free Acid ndi zwitterionic buffer yomwe imagwiritsidwa ntchito mu biochemistry ndi kafukufuku wa biology ya mamolekyulu mu pH ya 6.15 - 8.35 kuti igwiritsidwe ntchito pamaphunziro a biochemical.Protocol yanenedwapo yogwiritsa ntchito mchere wa BES buffered mu calcium phosphate mediated transfection of eukaryotic cell with plasmid DNA. adasintha sing'anga ya chiwombankhanga panthawi yoyesa ma cell a melanoma.Itha kugwiritsidwa ntchito ngati biobuffer kuti ifufuze zamadzimadzi zodzipangira zokha ma polima a heterometallic CuII/Li 3D coordination.

Njira yachilengedwe yokonzanso madzi apansi omwe ali ndi tetrachlorethylene (PCE) ndi trichlorethylene (TCE) angagwiritsidwe ntchito ngati zosinthazo ndizovomerezeka zachilengedwe.Maphunziro omwe ali ndi zikhalidwe zolemetsa za PCE- ndi TCE-owononga tizilombo toyambitsa matenda amapereka umboni wakuti, pansi pa mikhalidwe ya methanogenic, zikhalidwe zosakanikirana zimatha kuchotseratu PCE ndi TCE ku ethylene, mankhwala omwe amavomerezedwa ndi chilengedwe.Maphunziro a Radiotracer ndi [14C] PCE amasonyeza kuti [14C] ethylene inali mankhwala omaliza;kutembenuka kwakukulu ku 14CO2 kapena 14CH4 sikunawonedwe.Njira yochepetsera kuchuluka kwa njirayo idawoneka ngati kutembenuka kwa vinyl chloride kukhala ethylene.Kuti apitirize kuchepetsa kuchepa kwa PCE ndi TCE, kunali koyenera kupereka wopereka electron;methanol inali yothandiza kwambiri, ngakhale kuti haidrojeni, formate, acetate, ndi glucose adagwiritsidwanso ntchito.Kafukufuku ndi inhibitor 2-bromoethanesulfonate adanena kuti methanogens adagwira ntchito yofunika kwambiri pazochitika za biotransformations za PCE ndi TCE.
