Potential of fir wood using biotechnological methods

Pojam lignocelulozne biomase podrazumijeva poljoprivredni i šumski otpad, drvne ostatke i trave te dio industrijskog otpada. Njezin osnovni sastav uključuje tri strukturna polimera: celulozu, hemicelulozu i lignin. Primjena lignoceluloznih materijala u biotehnologiji postaje sve popularnija jer su to obnovljive sirovine koje ne konkuriraju tržištu hrane. Lignocelulozna biomasa može se koristiti za dobivanje rezličitih proizvoda visoke dodane vrijednosti, ali njezina biotehnološka primjena zahtiejva odgovarajuću predobradu. Metoda predobrade se bira prema vrsti sirovine, proizvodu, radnom mikroorganizmu i vrsti procesa. Općenito, zbog visokog udjela lignina, meko drvo je teže obraditi od nekih drugih lignoceluloznih sirovina. U ovom radu prikazan je u biotehnološki potencijal mekog drva s naglaskom na jelovinu.The term lignocellulosic biomass implies agricultural and forest wastes, wood residues and grass, as well as a part of industrial waste. The primary composition of lignocellulose includes three structural polymers: cellulose, hemicellulose and lignin. The use of lignocellulosic materials in biotechnological processess is becoming more popular because they are renewable raw materials that do not compete on the food market. Lignocellulosic biomass can be used to produce various types of high value-added products, but its biotechnological application requires the appropriate pretreatment. The pretreatment method is selected according to the type of raw material, product, working microorganism and the type od the proces. Generally, because of it's high percentage of lignin, soft wood is harder to process than some other lignocellulosic raw materials. In this thesis, the biotechnological potential of softwood with emphasis on fir wood is presented
