Eosin Methylene Xiav (los yog EMB ) Agar yog a Xaiv & Sib txawv Nruab nrab. Cov xaiv thiab sib txawv yam yog vim cov dyes Eosin Y thiab Methylene Xiav , thiab cov suab thaj lactose thiab sucrose hauv nruab nrab. Nws yog Xaiv vim nws txhawb qee cov kab mob kom loj hlob thaum inhibiting lwm tus.

Cov lus nug tseem yog, puas yog eosin methylene xiav agar xaiv lossis sib txawv?

Eosin methylene xiav agar ( EMB ) yog a xaiv thiab sib txawv nruab nrab siv los cais fecal coliforms. Eosin Y thiab methylene xiav yog pH qhov taw qhia dyes uas ua ke los tsim cov xim daj tsaus ntuj nag lossis daus ntawm pH qis; lawv kuj pab inhibit qhov kev loj hlob ntawm feem ntau Gram zoo kab mob.

Ib tus kuj yuav nug, vim li cas MacConkey agar xaiv nrog rau qhov sib txawv? MacConkey Agar (MAC) yog xaiv thiab sib txawv nruab nrab tsim los cais tawm thiab sib txawv ntawm kev nkag mus raws li lawv lub peev xwm ferment ferment lactose. Cov ntsev ntsev thiab siv lead ua violet tiv thaiv kev loj hlob ntawm cov kab mob Gram zoo. Lactose muab qhov chaw ntawm cov carbohydrates yooj yim, tso cai rau sib txawv.

Zoo sib xws, eosin methylene xiav agar xaiv rau dab tsi?

Eosin Methylene Xiav ( EMB ) agar yog ob leeg xaiv thiab qhov sib txawv ntawm kab lis kev cai nruab nrab. Nws yog xaiv kab lis kev cai nruab nrab rau Gram-negative cov kab mob (xaiv tiv thaiv kab mob Gram zoo) thiab feem ntau siv rau kev sib cais thiab sib txawv ntawm coliforms thiab quav quav coliforms.

Cov khoom xyaw twg ua rau EMB Agar sib txawv?

Eosin -Methylene Xiav ( EMB ) Agar yog a sib txawv nruab nrab rau kev kuaj pom ntawm Gram tsis zoo nkag mus rau cov kab mob. Qhov nruab nrab muaj peptone, lactose, sucrose, dipotassium phosphate, eosin thiab methylene xiav dyes.
