Abstract:
... Woody biomass is renewable only if sustainable production is imposed. An optimum and sustainable biomass stand production rate is found to be one with the incremental growth rate at harvest equal to the average overall growth rate. Utilization of woody biomass leads to a sustainable economy. Woody biomass is comprised of at least four components: extractives, hemicellulose, lignin and cellulose. W ...

Abstract:
... Bifidobacteria are indigenous components of human and animal gastrointestinal microbiota, and their health-promoting benefits have long been recognized. Of the 36 currently described species of the Bifidobacterium genus, 8 contain plasmids, most of which are cryptic. It is possible that plasmid presence is related very closely to environmental change, so in conditions of stress this presence could ...

Abstract:
... Natural ability to ferment the major sugars (glucose and xylose) of plant biomass is an advantageous feature of Escherichia coli in biofuel production. However, excess glucose completely inhibits xylose utilization in E. coli and decreases yield and productivity of fermentation due to sequential utilization of xylose after glucose. As an approach to overcome this drawback, E. coli MG1655 was engin ...
