BES, Acid lacag la'aan ah waa kaydiyaha zwitterionic kaas oo loo isticmaalo baadhista bayoloji iyo molecular ee kala duwanaanta pH ee 6.15 - 8.35 si balaadhan loogu dabaqi karo daraasadaha biochemical.Hab-maamuus ayaa lagu soo warramey isticmaalka cusbada BES buffered ee kalsiyum fosfateedka dhexdhexaadinta unugyada eukaryotic ee leh DNA plasmid. Dhexdhexaadiyaha Eagle ee wax laga beddelay inta lagu guda jiro baaritaanka xidhitaanka unugyada melanoma ee aadanaha.Waxa laga yaabaa in loo isticmaalo sidii biobuffer si loo baadho isku-ururinta dhexdhexaadka ah ee aqueous dhexdhexaadka ah ee polymers-ka isuduwidda heterometallic CuII/Li 3D.

Habka bayoolojiga ee dib-u-habaynta biyaha dhulka ee wasakhaysan tetrachlorethylene (PCE) iyo trichlorethylene (TCE) waxa kaliya oo la adeegsan karaa haddii badeecadaha isbeddelku ay yihiin kuwo deegaan ahaan la aqbali karo.Cilmi-baadhisyada dhaqamada kobcinta ee PCE-iyo TCE-ga-nooleyaasha hoos u dhigaya ayaa caddaynaya in, xaaladaha methanogenic, dhaqamada isku dhafan ay awoodaan inay si buuxda uga saaraan PCE iyo TCE ethylene, badeecada deegaan ahaan la aqbali karo.Daraasadaha raadiyaha raadiyaha ee [14C] PCE waxay muujiyeen in [14C] ethylene ay ahayd badeecada dhamaadka;beddelka muhiimka ah ee 14CO2 ama 14CH4 lama arag.Talaabada xadaynta heerka ee dariiqa waxay u muuqatay inay u badashay chloride vinyl una beddeshay ethylene.Si loo joogteeyo dekloriinta yaraynta PCE iyo TCE, waxa lagama maarmaan noqotay in la keeno ku deeqaha elektarooniga ah;methanol wuxuu ahaa kan ugu waxtarka badan, inkastoo hydrogen, formate, acetate, iyo glucose ay sidoo kale adeegeen.Daraasado lala sameeyay 2-bromoethanesulfonate inhibitor ayaa soo jeediyay in methanogens ay door muhiim ah ka ciyaareen isbeddellada biotransformations ee PCE iyo TCE.
