Sažetak

A huge amount of unused cereal straw originated from different industries is produced daily. These materials can be converted into different commercial products, among which biogas and bioethanol are perhaps the most important at present time. Based on their chemical composition straws are categorized as lignocellulose materials comprised mainly of polymers - lignin, cellulose and hemicellulose. Lignocellulose pretreatment for biofuels production is complex because cellulose is incorporated in lignin and hemicellulose matrix and therefore less prone to degradation either chemical or enzymatic. The methods most usually applied for lignocellulose materials pretreatment include thermochemical and/or mechanical treatments which are environmentally unfriendly. The available biological environmentally friendly degradation methods are based on the use of lignolytic fungi, rare organisms that can efficiently degrade lignocellulose polymers. This work seeks to address the following questions: the annual production of cereals straw in Europe, their chemical composition and possible biotechnological utilization as a substrate for production of different value-added products.
