Microbial enzymes implicated in plant cell hydrolysis may have several potential aplications such as biomass degradation biocatalysts or with biofuel production. Bark beetles establish symbiosis with several microbial strains which play different roles benifitting the beetle, as the production of hydrolytic enzymes to degrade the ingested wood, the protection against mirobial antagonist or the detoxification of the environment. Fungal symbionts have been traditionally the best studied, but several recent research with bacterial symbionts of several bark beetle species show that bacterial also display important functions for the host. In this study, the bacterial communities of the bark beetle species Cryphalus piceae and Pithophtorus pithophtorus, collected in the Czech Republic from pine and fir trees, respectively, were isolated and 55 out of 89 samples were identified by 16S rRNA gene amplification and sequencing. Members of the genera Erwinia, Pantoea, Curtobacterium, Yersinia, Pseudomonas and Staphylococcus were detected. The isolates were object of study for their possible biotechnological potential in (ligno)cellulose materials degradation by screening several enzymes implicated in plant cell hydrolysis, as cellulases, xylanases, amylases, laccases, as well as their capability for colorant...
