Fermentative Conversion of Two-Step Pre-Treated Lignocellulosic Biomass to Hydrogen
PublicationFermentative hydrogen production via dark fermentation with the application of lignocellulosic biomass requires a multistep pre-treatment procedure, due to the complexed structure of the raw material. Hence, the comparison of the hydrogen productivity potential of different lignocellulosic materials (LCMs) in relation to the lignocellulosic biomass composition is often considered as an interesting field of research. In this study,...

The influence of pre- and postharvest treatments on selected biological and epigenetic activities of Brassica sprouts
PublicationIntroduction The Brassica vegetables are rich in glucosinolates (GLs), which are enzymatically hydrolysed to bioactive isothiocynates (ITC) and indoles, regarded as the most promising chemopreventing agents. However, in the majority of brassica sprouts the GL conversion into these beneficial derivatives occurs at the level of about 1 %, while in cabbage leaves exceeds 70%. Since sprouts represent plant material, which is frequently...

Gender approaches to evolutionary multi-objective optimization using pre-selection of criteria
PublicationA novel idea to perform evolutionary computations (ECs) for solving highly dimensional multi-objective optimization (MOO) problems is proposed. Following the general idea of evolution, it is proposed that information about gender is used to distinguish between various groups of objectives and identify the (aggregate) nature of optimality of individuals (solutions). This identification is drawn out of the fitness of individuals...
