Sažetak
Nowadays as the availability and accessibility of fossil fuels is significantly declining, the need for the production of biofuels from various renewable sources is becoming increasingly interesting. Biodegradability, non-toxicity and low pollution emissions are merely some properties making biogas, biodiesel and bioethanol more environmentally friendly fuels. Solid-state fermentation could be a suitable technology for the production of value-added products by utilization of the renewable waste materials, which makes it also economically feasible. So far, this technology was used for production of enzymes, organic acids, mushrooms, flavor and aroma compounds, pigments, polysaccharides, hormones, human food and animal feed. Different type of bioreactors have been developed and successfully used for solid-state fermentation of broad range of substrates and in production of value- added products. Solid-state fermentation on lab-, pilot- and industrial-scale will be demonstrated as part of anaerobic degradation of several waste materials such as brewer's spent grain (mono-substrate) and whey and cow manure (co- digestion). The anaerobic process was divided into a reactor for the anaerobic digestion of solids (SS-AD - Solid State Anaerobic Digestion reactor), in which hydrolysis mainly took place and into a reactor with granular biomass (GBR Granular Biomass Reactor) in which most of the biogas production took place [1]. Microreactors are widely used in different fields of chemical and pharmaceutical industry, biotechnology and medicine. The application of different microreactor systems in intensification of the biodiesel production process is widely studied. However, previous studies of the application of microreactor technology in the production of biodiesel were limited to the use of chemical catalysts. Mild reaction conditions, absence of unwanted by-products (soap), reusability, simple separation and purification of the resulting biodiesel as well as lower energy consumption are some of the many advantages that make the enzyme lipase – a biocatalyst – a better choice than traditional chemical catalysts in the process of biodiesel production [2]. Different microreactor systems utilising a commercially available lipase and a lipase produced by solid-state fermentation using the fungus T. lanuginosus were used for transesterification of fresh and and waste cooking oil while biodiesel was separated using integrated microseparation unit. Selected examples are clear demonstration of environmentally friendly and economic technologies used for efficient production of biofuels on micro-, lab-, pilot- and industrial scale.
