Abstract
Potencijalne lignocelulozne sirovine u Republici Hrvatskoj, koje bi se mogle koristiti kao temelj buduće biotehnološke proizvodnje, su otpad koji nastaje u poljoprivredi, šumarstvu, prehrambenoj i drvnoj industriji. Glavne komponente lignoceluloznih sirovina su celuloza, hemiceluloza i lignin. Kako bi se dobili fermentabilni šećeri, koje radni mikroorganizmi mogu metabolizirati, potrebno je podvrgnuti kompleksne lignocelulozne sirovine određenim postupcima predobrade i hidrolize. Cilj je postići što veći stupanj hidrolize hemiceluloze, ukloniti lignin te smanjiti kristaliničnost celuloze. Metode predobrade dijele se na fizikalne, kemijske, fizikalno-kemijske i biološke, a treba ih prilagoditi ovisno o sastavu sirovine koja se koristi. U radu su opisani primjeri predobrade tvrdog drveta s naglaskom na bukovinu te njihove prednosti i nedostatci.
Abstract (english)
Potential lignocellulosic raw materials in Croatia, which could be used as the basis of future biotechnological production, are wastes derived from agriculture, forestry, food and wood industries. The main components of lignocellulose raw materials are cellulose, hemicellulose and lignin. In order to obtain fermentable sugars, which can be metabolized by working microorganisms, it is necessary to subject the complex lignocellulosic raw materials to certain pretreatment and hydrolysis procedures. The aim is to achieve the highest percentage of hemicellulose hydrolysis, to remove lignin and to reduce the crystallinity of cellulose. Pretreatment methods are divided into physical, chemical, physico-chemical and biological, and need to be adjusted depending on the composition of the used raw material. The paper describes examples of hardwood pretreatment with an emphasis on the beech wood as well as their advantages and disadvantages.
