Original Abstract

With the rapid development of industry and its deepening impact on climate change, interest in the possible use of alternative energy sources has been growing in recent years. On of suitable type of renewable energy is the production of combustible gases such as methane or hydrogen. The advantage of hydrogen is that when burning it, only water vapour is produced. One of the possible avenue for hydrogen production could be biotechnological production using microorganisms capable of producing it using carbohydrate-rich waste materials. Among the promising hydrogen producers are bacteria of the genus Clostridium. These bacteria, which are strict anaerobes, produce hydrogen acetic and butyric fermentation, using organic matter as the primary source of hydrogen and energy. These organic substrates include glucose and other hexoses, lactose, sucrose, starch, etc.This work focused on the description of hydrogen production by the anaerobic bacteria Clostrodium butyricum and Clostridium tyrobutyricum with a focus on the optimal conditions for biohydrogen production such as culture time, suitable medium, etc. Furthermore, first part of this work was focused on the development of a suitable apparatus for the collection of the produced gas mixture followed by the analysis of the composition of produced gas mixture by Hiden QGA ("quantitative gas analysis"). The second part of this work was aimed at verifying the possibility of biotechnological treatment of the liquid fraction of hydrogen production. These supernatants were analyzed by ion chromatography (IC) to determine the organic acid content. Following this, the use of this material as a substrate for the production of polyhydroxyalkanoates by already known PHA producers was verified.
