Dichtiar S. Development of the biotechnology for hydrobionts mass forms processing.

In the Thesis solved the issue of the development of non-waste biotechnology for receiving the 2nd generation biofuel (gas mixture containing methane) with the use of a new renewable substrate – biomass of cyanobacteriae and further application of a digestate as organic and mineral fertilizer for the purposes of agriculture and forestry. Physical and chemical aspects of bio-methanogenesis were disclosed and researched; the sequence of bio-chemical reactions in production of biogas from bluegreen algae was established and their features were determined. The species composition of the initial substrate for bio-methanogenesis and its microbiological properties were determined. The chemical composition of biogas samples of different origin has been established and comparative analysis of their physical properties has been carried out. The traditional biotechnology of biogas production has been improved through the use of a new substrate – anexcess hydrobionts organic matter from «blooming» spots, which consists mainly of the cyanobacteria biomass. A new environmentally safe technological process, which ensures rational use of natural resources, has been developed.
