Pozycja Plant biomass degradation supported by non-enzymatic proteins(Lodz University of Technology Press, 2017) Madaj, Rafał; Kalinowska, Halina; Sobiecka, ElżbietaLignocellulosic biomass, rich in potential carbon sources and value added products, has been intensively investigated in scope of its costefficient and effective decomposition. Many methods were developed, physicochemical or biological. Nevertheless, they are either expensive, inefficient or pose threat to the environment. Recently discovered proteins, lacking any hydrolytic activity, can be a key to solve problems associated with a slow process of enzymatical, eco-friendly degradation. These proteins belong to three related groups – swollenins, expansins and loosenins. Using different molecular mechanisms, they disrupt hydrogen bonds within cellulose chains, enabling enzymes to perform hydrolysis leading to decomposition of lignocellulosic complex.Pozycja Utilisation of nitrocompounds(Lodz University of Technology Press, 2016) Madaj, Rafał; Kalinowska, Halina; Sobiecka, ElżbietaThis paper is a review of methods of biological, chemical and physical utilisation of nitrocompounds, extremely toxic xenobiotics that are abundant in the biosphere and are recalcitrant to biodegradation. Due to their unique physicochemical properties the nature itself has significant problem with complete degradation of nitroxenobiotic substances. There are number of methods developed in order to prevent further contamination of the environment leading to defoliation, inhibition of growth of plants and has adverse health effects on animals. Their abundance, deriving mainly from military industry, poses a serious threat to biosphere and current methods of their utilisation require further optimization.
