BES, Dawb Acid yog zwitterionic tsis nyob rau hauv biochemistry thiab molecular biology tshawb fawb nyob rau hauv pH ntau ntawm 6.15 - 8.35 rau dav siv rau kev tshawb fawb biochemical.Cov txheej txheem tau tshaj tawm rau kev siv BES buffered saline nyob rau hauv calcium phosphate mediated transfection ntawm eukaryotic hlwb nrog plasmid DNA.A zwitterionic buffer uas yog siv nyob rau hauv kev tshawb fawb nyob rau hauv lub pH ntau ntawm 6.15 - 8.35; BES tej zaum yuav ua hauj lwm raws li binding tsis nyob rau hauv Hloov kho Eagle's nruab nrab thaum lub sij hawm binding assay ntawm tib neeg melanoma hlwb.Nws tuaj yeem siv los ua biobuffer los tshawb xyuas cov dej nruab nrab ntawm nws tus kheej ntawm heterometallic CuII / Li 3D coordination polymers.

Cov txheej txheem lom neeg rau kev kho cov dej hauv av uas muaj kab mob tetrachlorethylene (PCE) thiab trichlorethylene (TCE) tsuas yog siv tau yog tias cov khoom hloov pauv tau txais ib puag ncig.Kev tshawb fawb nrog cov kab lis kev cai zoo ntawm PCE- thiab TCE-degrading microorganisms muab pov thawj tias, nyob rau hauv cov xwm txheej methanogenic, cov kab lis kev cai sib xyaw muaj peev xwm ua kom tag nrho dechlorinate PCE thiab TCE rau ethylene, cov khoom lag luam uas tau txais ib puag ncig.Radiotracer kev tshawb fawb nrog [14C]PCE qhia tias [14C]ethylene yog cov khoom siv davhlau ya nyob twg;Kev hloov pauv tseem ceeb rau 14CO2 lossis 14CH4 tsis tau pom.Tus nqi-txheej kauj ruam hauv txoj hauv kev tau tshwm sim tau hloov pauv ntawm vinyl chloride rau ethylene.Txhawm rau txhawb nqa kev txo qis dechlorination ntawm PCE thiab TCE, nws yog qhov tsim nyog los muab cov khoom siv hluav taws xob;methanol yog qhov zoo tshaj plaws, txawm tias hydrogen, formate, acetate, thiab qabzib kuj tau txais kev pab.Cov kev tshawb fawb nrog cov inhibitor 2-bromoethanesulfonate qhia tias methanogens ua lub luag haujlwm tseem ceeb hauv kev soj ntsuam biotransformations ntawm PCE thiab TCE.
