Assessment of the Biodiversity of Samples Used for Isolation of Microbial Strains Capable of Converting Straw Destined as a Substrate for Biogas Plant

Abstract

Despite the large potential of straw as a substrate for biogas production, its use is marginal at present. This is mainly due to the structure of materials of that type, where cellulose, hemicellulose and lignin prevail [Mussato and Teixeira, 2004; Adapa et al., 2009; Chaturvedi and Verma, 2013]. Such a structure prevents the effective use of straw by biogas reactor microflora [Frei, 2013]. Great hopes are placed on the possibility of using microorganisms in the straw pretreatment [Dorado et al, 1999; Feng et al., 2012].
