Isha vanillin, aldehyde aldehyde aldehyde, dimethyl sulfoxide, Lignin (Dealkaline) waxay noqon kartaa fidiyaha balaastikada phenolic, si loo xoojiyo caag (esp for kabaha kabaha), sida wax lagu daro saliidda dhoobada, si loo dejiyo emulsion asphalt, si loo dedejiyo borotiinka.

Muuqaalka guud ee lichens waxaa lagu sifeeyaa qolof ah (waxay sameeyaan qolof dhuuban oo siman oo ku yaal substratum), foliose ama fruticose (qaab toosan, foomamka laamo leh, oo u eg geedo yaryar).Lichens waxay si tartiib tartiib ah u koraan min dhowr milimitir ilaa dhowr mitir sannadkii.Waxay ku tarmaan inta badan horumarinta apothecia ama perithecia, sameynta lichens cusub biqilka ascospores kaliya marka ay joogaan lamaanaha algal ee maqnaanshaha fungusku dhinto.
Ku dhawaad ​​700 oo kiimikooyin ah, kuwaas oo u gaar ah lichens, ayaa ka caawiya lichens si ay u noolaadaan oo ay uga hortagaan weerarada bakteeriyada, fangaska kale iyo dhirta daaqsinta.
Lichens waxay ka tirsan yihiin bulshooyinka qolofta ciidda leh waxayna caawiyaan xasilinta carrada, gaar ahaan meelaha saxaraha ah.Cyanolichens waxay gacan ka geystaan ​​hagaajinta nitrogen ee nidaamka deegaanka ee ay ku koraan.LicheGare waxaa loo isticmaalaa in lagu aqoonsado da'da oogada (oo ay ku koraan) farsamo, loo yaqaan lichenometry.
Lichens waa tilmaamayaasha wasakhowga sababtoo ah dareenkooda kala duwan ee sulfur dioxide (SO2), nitrogen dioxide (NO2) iyo ozone, iyo sidoo kale awoodda ay u leeyihiin inay nuugaan oo ururiyaan biraha culus iyo radionuclides.
Walxaha sida midabka, sunta, antibiyootiga, iwm. waxaa laga helaa lichens, kuwaas oo si gaar ah waxtar u leh sida isha dheeha (tusaale, Roccella, bixinta litmus), daawooyinka iyo cadarka.Qaar ka mid ah lichens, sida cawska Iceland iyo cawska deerada, ayaa cunto ahaan loogu isticmaalaa gobollada arctic.
