Potential of using beech wood using biotechnological methods

Lignocelulozne sirovine dostupne u Hrvatskoj čini uglavnom otpad iz poljoprivrede, šumarstva, prehrambene i drvne industrije. Tri su osnovna strukturna polimera lignoceluloze: celuloza, hemiceluloza i lignin. Da bi se lignoceluloza mogla koristiti u biotehnološkim procesima, potrebno je provesti odgovarajuću predobradu sirovine kojom se razara njezina čvrsta struktura. Postoje različite metode predobrade, a dijele se na fizikalne, kemijske, fizikalno-kemijske i biološke. U ovom radu dan je pregled prednosti i nedostataka pojedinih metoda predobrade lignoceluloznih sirovina. Također je prikazan biotehnološki potencijal tvrdog drva s naglaskom na bukovinu.Lignocellulosic raw materials awailable in Croatia are mainly waste from agriculture, forestry, food and wood industry. Lignocellulose mainly consists of three structural polymers: cellulose, hemicellulose and lignin. In order to use lignocellulose in biotechnological processes, it is necessary to perform an appropriate pretreatment of the raw material which disrupts it's solid structure. There are various pretreatment methods which are classified into physical, chemical, physicochemical and biological treatment. This thesis points out some advantages and disadvantages of the most common methods for lignocellulosic biomass pretreatment. It also gives insight into the biotechnological potential of hardtwood with emphasis on beech wood
