Izilondoloziizinto ezivimbela ukukhula kwama-microorganisms ngaphakathi komkhiqizo noma ezivimbela ukukhula kwama-microorganisms asabelayo ngomkhiqizo.Ama-preservatives awavimbeli nje kuphela i-metabolism yamagciwane, isikhunta nemvubelo, kodwa futhi athinta ukukhula nokukhiqizwa kwawo.Umphumela wokulondoloza ekubunjweni uthintwa izici ezihlukahlukene, njengezinga lokushisa lendawo ezungezile, i-PH yokubunjwa, inqubo yokukhiqiza, njll. Ngakho-ke, ukuqonda izici ezihlukahlukene kusiza ukukhetha nokusebenzisa izilondolozi ezihlukahlukene.
Izici ezithinta ukusebenza kwezilondolozi zezimonyo zimi kanje:
A. uhlobo lwezilondolozi
Imvelo ye-preservative ngokwayo: ukusetshenziswa kokugxila kwezilondolozi kanye nokuncibilika komthelela omkhulu ekusebenzeni kahle.
1, Ngokuvamile, ukugxila okuphezulu, kusebenza kahle kakhulu;
2, Izilondolozi-manzi ezincibilikayo zinokusebenza okungcono kwezilondolozi: ama-microorganisms ngokuvamile aphindaphindeka esigabeni samanzi somzimba we-emulsified, emzimbeni owenziwe nge-emulsified, i-microorganism izokhangiswa ku-interface yamanzi kawoyela noma ihambe esigabeni samanzi.
Ukusebenzelana nezinye izithako ekwakhiweni: ukungasebenzi kwezivimbelakuvunda ngezinye izinto.
B. Inqubo yokukhiqiza umkhiqizo
Imvelo yokukhiqiza;izinga lokushisa lenqubo yokukhiqiza;indlela izinto ezifakwa ngayo
C. Umkhiqizo wokugcina
Okuqukethwe kanye nokupakishwa kwangaphandle kwemikhiqizo kunquma ngokuqondile indawo ephilayo yama-microorganisms ezimonyoni.Izici ezingokomzimba zemvelo zihlanganisa izinga lokushisa, imveloInani le-pH, ingcindezi ye-osmotic, imisebe, ingcindezi emile;Izici zamakhemikhali zihlanganisa imithombo yamanzi, imisoco (imithombo C, N, P, S) , umoya-mpilo, nezici zokukhula kwemvelo.
Ingabe kuhlolwa kanjani ukusebenza kahle kwezilondolozi?
I-minimal inhibitory concentration (MIC) inkomba eyisisekelo yokuhlola umthelela wezilondolozi.Uma inani le-MIC liba lincane, umphumela uba phezulu.
I-MIC yezilondolozi itholwe ngokuhlolwa.Ukugxiliswa okuhlukene kwezivimbelakuvunda kwengezwa ku-liquid medium ngochungechunge lwezindlela zokuhlanjululwa, bese kuthi ama-microorganisms afakwe i-inoculated futhi akhuliswe, i-lowest inhibitory concentration (MIC) yakhethwa ngokubheka ukukhula kwama-microorganisms.
