Opis:
Among currently developed biofuel and green-power technologies, technological development of lignocellulose biomass-based production of ethanol will be particularly important in a short time perspective as those specific activities constitute an intermediary stage in the process of developing integrated processes of biomass conversion in the route to the universal energy carrier - hydrogen or electricity. Agricultural biorefinery or agri-refinery which converts agricultural biomass to a wide spectrum of biofuels and bioproducts is considered as the key element of the future economy. The biorefinery which produces biofuels and generates bioenergy will constitute the so called agri-energy complex - a local power unit implemented in the system of dispersed energy generation. It is worth noticing that agri-refinery will integrate three fundamental drivers of sustainable development of rural areas - bioeconomics, environment and society. This paper aims at elaborating the conceptual framework of the agri-refinery in the aspect of conversion of agricultural lignocellulosic biomass into bioethanol and other bioproducts as well as the future economy and sustainable development.

Opis:
Polycyclic aromatic hydrocarbons (PAHs) are widely spread environmental pollutants mainly originating from anthropogenic sources such as fossil fuel combustion, industries, and others. Although a large body of literature exists on the toxicity and carcinogenicity of PAHs, primarily benzo[a]pyrene, toxicity data for phenanthrene deriveratives are very limited. The main aim of the experiment was to investigate if there exists correlation between molecular structure and mutagenic activity of four phenanthrene derivatives: 1 methylphenanthrene, 4 methylphenanthrene, 1 phenylphenanthrene, and 4 phenylphenanthrene. An Ames assay using two strains of histidine dependent Salmonella Typhimurium (TA98 and TA100) was conducted to assess the mutagenic activity of studied compounds both in the presence (+S9) and in the absence (-S9) of an exogenous source of metabolic activation. The compounds were also tested in an in vitro chromosome aberration assay in which V-79 cells were exposed to the phenanthrene derivatives investigated both in the presence and in the absence of metabolic activation. The phenylphenanthrenes showed no mutagenic effect. These compounds occasionally induced significant decrease in the number of revertants in the Ames test. The greatest mutagenic effects were observed for 1 methylphenanthrene after metabolic activation (+S9). In the micronucleus test the greatest mutagenic effect was observed for 4 methylphenanthrene also in the presence of metabolic activation system. The results obtained are comparable to those reported earlier for the methylphenanthrenes.
