Uma kucatshangelwa iqiniso lokuthi ama-aerosol aqoqiwe ama-microbial ahlala endaweni yesihlungi, okunye okungenzeka kokuhlangana kwawo okulandelayo kanye nokuphinda kufakwe umoya emoyeni emuva kusithwali segesi akukwazanga ukunganakwa. Izinhlayiya ezifakwe umoya kabusha zisengaphila zidale ubungozi obukhulu kubahlali nendawo. Le nkinga ingaxazululwa ngokungeza izinto ezibulala amagciwane kumthwali wegesi noma ukwenza izinqubo ezithile zokungawusebenzisi ngokuqondile endaweni yokuhlunga, okwenza izinhlayiya ezincane zingasebenzi ezimeni zokuphinda kufakwe umoya emoyeni.

Kunezindlela ezithile zobuchwepheshe ezitholakalayo zokubulala amagciwane ngama-microbial. Kubandakanya ukubola kwe-photocatalytic kwama-microbes endaweni ye-titanium oxide ekhanyiswa i-ultraviolet (UV; Vohra et al. 2006; Grinshpun et al. 2007), ukubola kwe-infrared (IR) okusekelwe emisebeni okushisayo (Damit et al. 2011), kusetshenziswa amakhemikhali ajovwe ngokuqondile ngomjovo kusithwali somoya noma sisetshenziswe endaweni yokuhlunga (Pyankov et al. 2008; Huang et al. 2010), nabanye. Phakathi kwezinhlobonhlobo zezibulala-magciwane, amanye amafutha emvelo abukeka ethembisa ngenxa yemvelo ephansi noma engenabo ubuthi, ikakhulukazi esesimweni esixutshiwe (Carson et al. 2006). Phakathi neminyaka eyishumi edlule, izinhlobonhlobo zamafutha abalulekile avela ezitshalweni ziye zahlolwa ukuze kuhlolwe umsebenzi wazo wokulwa namagciwane (Reichling et al. 2009).

Ukusetshenziswa okungaba khona kwamafutha, njengamafutha esihlahla setiye (TTO) namafutha eucalyptus (EUO), njengezibulala-magciwane kuboniswe ngokucacile ocwaningweni lwakamuva lwe-in vitro mayelana ne-antibacterial (Wilkinson and Cavanagh 2005; Carson et al. 2006; Salari et al. 2006) ; Hayley and Palombo 2009), antifungal (Hammer et al. 2000; Oliva et al. 2003), kanye nemisebenzi elwa namagciwane (Schnitzler et al. 2001; Cermelli et al. 2008; Garozzo et al. 2011). Ngaphezu kwalokho, kwaboniswa ukuthi amafutha abalulekile ayingxube ehlukahlukene, enokwehlukahlukana okukhulu kwenqwaba yezakhi, kuye ngezimo zokukhula emasimini (Kawakami et al. 1990; Moudachirou et al. 1999). Umsebenzi we-antimicrobial we-TTO ubizwa ngokuyinhloko ku-terpinen-4-ol (35-45%) kanye ne-1,8-cineole (1-6%); kodwa-ke, ezinye izakhi ezifana ne-a-terpineol, i-terpinolene, ne-a- kanye ne-c-terpinene nazo zivame ukuba khona futhi zingase zibe nomthelela ekubulaweni kwamagciwane amancane (May et al. 2000). I-EUO evela ezinhlotsheni ezahlukene ze-Eucalyptus iqukethe i-1,8-cineole, i-a-pinene, ne-a-terpineol njengezinhlanganisela ezinkulu ezivamile (Jemâa et al. 2012). I-EUO esekwe ngokwemithi ivamise ukunothiswa kufika ku-70% ukugxilisana kwe-1,8-cineole.

Muva nje, siphakamise ubuchwepheshe obusekelwe ekuhlanganiseni izihlungi ze-fibrous nge-TTO, futhi sabika imiphumela yocwaningo olunokwenzeka ekubulaweni kwamagciwane (Pyankov et al. 2008) kanye nezinhlamvu zesikhunta (Huang et al. 2010). Kulezi zifundo, i-TTO yasetshenziswa njengazo zombili, isihlungi sithuthukisa imidiya kanye nesibulala-magciwane kuma-aerosol amagciwane kanye nesikhunta athwetshulwe endaweni yesihlungi. Uma kucatshangelwa intshisekelo eqinile yamanje ocwaningweni oluhlobene nomkhuhlane, ucwaningo lwamanje luwukuqhubeka okunengqondo kophenyo lwethu lwangaphambilini sigxile ekuhloleni umsebenzi wokunqanda amagciwane wamafutha abalulekile (i-TTO kanye ne-EUO) ekuvinjweni kwegciwane lomkhuhlane womoya.
