Enzymatic activities behind degradation of glucosinolates
PublicationMyrosinase (thioglucosidase, EC 3.2.1.147) is the enzyme responsible for the hydrolysis of glucosinolates (GLs). In plant tissue, myrosinase and GLs are sequestered in separate cellular compartments. As a result of cell disruption, e.g., after pathogen attack or on chopping or grinding during food preparation, the myrosinase comes into contact with GLs and catalyzes the hydrolysis of thioglucosidic bond in GL structure. Consequently,...

Performance of ASON/GMPLS architecture in condition of wavelength conversion and without wavelength conversion
PublicationThe paper regards the problem of ASON/GMPLS performance in condition of wavelength and without wavelength conversion. The authors present influence analysis in condition of wavelength and non-wavelength conversion on the ASON/GMPLS control plane performance represented by mean Connection Set-up Time E (CST) and request loss probabilities. The offered traffic to the transport layer and request intensity have been changed for evaluation...

Thermal Biomass Conversion: A Review
PublicationIn this paper, the most important methods of thermal conversion of biomass, such as: hydrothermal carbonization (180–250 °C), torrefaction (200–300 °C), slow pyrolysis (carbonization) (300–450 °C), fast pyrolysis (500–800 °C), gasification (800–1000 °C), supercritical steam gasification, high temperature steam gasification (>1000 °C) and combustion, were gathered, compared and ranked according to increasing temperature. A comprehensive...

Photocatalysts for Solar Energy Conversion
PublicationPhotocatalytic oxidation over suspended solid photocatalysts (e.g., titanium dioxide) has been proposed as a sustainable process for treatment and purification of water and wastewater as well as the process for photoconversion of solar energy to hydrogen, methane, and other low hydrocarbons. Solar radiation could be used to drive heterogeneous electrochemical reactions at the surface of an optically active photocatalyst (e.g.,...

Modeling organic nitrogen conversions in activated sludge bioreactors
PublicationOpracowano model przemian azotu organicznego (Norg)jako rozszerzenie Modelu Osadu Czynnego Nr 2d (ASM2d). Nowy model zawiera trzy frakcje Norg: rozpuszczoą, koloidalną i zawesinową. Każda frakcja została podzielona na dwie podfrakcje - rozkładalną i nierozkładalną. Model został zweryfikowany w oparciu o wyniki badań eksperymentalnych w oczyszczalni ścieków Gdańsk-Wschód.

Modeling organic nitrogen conversions in activated sludge bioreactors
PublicationFor biological nutrient removal (BNR) systems designed to maximize nitrogen removal, the effluent total nitrogen (TN) concentration may range from 2.0 to 4.0 g N/m3 with about 25-50% in the form of organic nitrogen (ON). In this study, current approaches to modeling organic N conversions (separate processes vs. constant contents of organic fractions) were compared. A new conceptual model of ON conversions was developed and combined...

Sandwich Biobattery with Enzymatic Cathode and Zinc Anode Integrated with Sensor
PublicationCarbon paper covered with side-naphthylated multi walled carbon nanotubes was used as the conducting support for the construction of a biocathode in a hybrid biofuel cell. Laccase Carrena unicolor enzyme was employed as the catalyst for the 4e reduction of oxygen and a zinc disc covered with hopeite was used as the anode. Derivatized carbon nanotubes increase the working surface of the electrode and provide direct contact with...
