Pressure Hydrolysis of Protein in Waste of Chicken Cartilage and Feathers in the Presence of Carbon Dioxide
Hanika, Jiří ; Šolcová, Olga ; Kaštánek, P.
Proteins hydrolysis of chicken cartilage and feathers were carried out at increased temperature (till 120 oC) and in the presence of carbon dioxide (partial pressure 10 20 bar), which dissociates in water solution forming an acidic environment supporting the reaction. Carbon dioxide was easily detachable from the reaction mixture at the end of process. Bench scale tests were performed using a mixed autoclave (volume 2.5 lt, mixing time 5 hr). The resulting aqueous solution of amino acids contained in the same representation as peptides forming collagen and keratin of raw material. The reaction conversion was proportional to carbon dioxide partial pressure.

BIORAF – Biorefinery Research Centre of Competence
Topka, Pavel ; Hajšlová, J. ; Demnerová, K. ; Cepák, Vladislav ; Vosátka, Miroslav ; Jiřičný, Vladimír ; Jandejsek, Z. ; Kopenec, J. ; Šmejkal, M. ; Kaštánek, P. ; Šolcová, Olga
The project, which started in 2012, creates an interdisciplinary center with high innovation potential for sustainable utilization of renewable sources, and will bring the Czech Republic to the leading position in next-generation biorefinery within next eight years. The project links the private sector with experts from different fields of science (e.g., biosciences, phycology, analytical chemistry, enzymology, microbiology, chemical and biochemical engineering, material engineering, etc.).

Recent Advances in Outdoor High-Density Cultivation of Novelty Micro-Algae Strain with High Content of Lipids
Kaštánek, Petr ; Kaštánek, František ; Cepák, Vladislav
The objective of the study was the pilot plant examination of a newly developed integrated process for autotrophic cultivation of useful micro-algae. The process utilizes waste carbon dioxide as a source of carbon and yields simultaneously products that can be utilized in food and cosmetic industries, turned into biodiesel and/or used as a supplement in animal feed. At present, the cultivation of micro-algae merely for the production of biofuels is not economically viable. In the proposed process, the economy is improved by complex utilization of the micro-algae for simultaneous integrated manufacturing of several products that may be priced at different levels. In this way, the overall economy of the process is positive.
