Yam Khoom Lub Npe Ntau Yam Khoom Siv Tshuab Txheej Txheem Plate-count Bacteria
Cov qauv kev tshawb fawb
Tag nrho cov kab mob suav txheeb xyuas reagent siv enzyme substrate thev naus laus zis txhawm rau txheeb xyuas tag nrho cov kab mob suav hauv dej.Cov reagent muaj ntau yam tshwj xeeb enzyme substrates, txhua tus tsim los rau cov kab mob sib txawv.Thaum cov enzymes sib txawv yog decomposed los ntawm enzymes tso tawm los ntawm cov kab mob sib txawv, lawv tso cov fluorescent pawg.Los ntawm kev soj ntsuam tus naj npawb ntawm cov fluorescent hlwb nyob rau hauv lub teeb ultraviolet nrog lub wavelength ntawm 365 nm los yog 366 nm, tag nrho cov nqi ntawm cov colonies tuaj yeem tau los ntawm kev saib lub rooj.
