TYPHABOARD is a sustainable construction and thermal insulation board made of cattail (lat. typha) and magnesite as a binder. It is characterized by a unique combination of high mechanical strength, highly insulating properties, relatively high diffusion openness, inflammability, and a sustainable lifecycle. The TYPHABOARD concept includes ecological benefits related to the systematic planting of the raw material typha in Bulgaria, the production of TYPHABOARD, and its application as a stabilizing, insulating and passive indoor climate controlling element in the framework structure of the historic typology of the Black Sea House. The entire technological and organizational process provides a sustainable solution for the operation of peat areas by planting typha (which acts as a natural water and ground filter), for the engagement of work forces in structurally underdeveloped regions, for sustainable ecological and social regional development, as well as for the sustainable retrofit of existing historic Black Sea Houses. The building and ecological system TYPHABOARD can be successfully introduced and applied in Bulgaria. In addition to the scientific and the practical study, the political eligibility of this was proved and officially permitted by the relevant public bodies in Bulgaria.

The increasing in tourist flow to the Republic of Crimea, as well as the acceleration of the pace of life of the population led to an increase in demand for finished fish culinary products. In this regard, there is a need to create a new fish culinary product of long-term storage from the raw materials of the Azov-Black Sea basin. The Black Sea mullet (Mugil cephalus) was chosen as fish raw material, the catch volume of which has been steadily increasing in recent years. Sous-vide technology - is a progressive technology, which is characterized by low-temperature modes of heat treatment, resulting in a product with unique organoleptic characteristics that are superior to traditional types of processing of fish raw materials. Fish and vegetables prepared using the sous-vide technology are distinguished by tenderness and juiciness, the aroma of the finished dish is enhanced. During the development of new product technology, the optimal technological parameters (temperature and process duration) were determined for heat treatment of fish fillet in vacuum based on mathematical modeling. The research was carried out on the equipment of the sector of technologies of processing of water biological resources of the department "Kerchenskiy" of the Azov-Black Sea branch of Russian Federal Research Institute of Fisheries and Oceanography. Heat treatment of samples was carried out in a water bath of LB-63 according to the plan of an experiment in the range from 55 to 70 ? with lasting from 15 to 30 min. For packing of a product the vacuum device Solis Vac Premium was used. A regression model was constructed consisting of the objective function determined by the microbiological index QMAFAnM. The software "STATGRAPHICS Plus Version 5.0" was used to plan the experiment and determine the optimal technological parameters of the fish culinary product..

Collagen Hydrogels

Collagen hydrolysers are three-dimensional polymeric materials with limited cross-linking and high hydrophilicity, having multiple medical applications. The most used collagen is the one extracted from bovine skin, which is now the industrial source of collagen. Due to the outbreak of some threatening diseases such as BSE, transmissible spongiform encephalopathy, foot-and-mouth disease, researchers have sought a safer alternative to collagen. This was the marine resource, which offered multiple opportunities to capitalize on clean sea-water raw material. This paper presents a comparative study of the physico-chemical properties of collagen hydrogels derived from collagen obtained from calf and skin from the Black Sea. Physico-chemical and spectrophotometric analyzes were performed to determine the structure. Studies have been conducted to analyze rheological behavior, antioxidant activity and antimicrobial activity. The total antioxidant capacity (ACL) is higher for collagen mixtures with 40% ethyl alcohol and shows higher values for fish collagen compared to calf collagen. Antimicrobial analysis shows that all collagen hydrogels show antimicrobial activity, both gram-positive (Staphylococcus aureus ATCC 6538P) and gram-negative (Escherichia coli ATCC 10536), which increases with increasing collagen concentrations.

Marine Biomass

During the past years, it became obvious that the ecosystem presents a marine algae excedent, which should be utilized in one way or another. In the marine world, algae have been intensely studied, but the Black Sea seaweeds are not sufficiently harnessed. To survive in such various diverse and extreme environments, macroalgae produce a variety of natural bioactive compounds and metabolites, such as polysaccharides, polyunsaturated fatty acids, and phlorotannins. In the Black Sea there are three species of green algae: Ulvae lactuca sp., Enteromorpha intestinalis and Cladophora sp. The superior exploitation of the marine biomass represents a highly important resource for the pharmaceutical industry, supplying raw material for the extraction of bioactive substances (vitamins, polysaccharides, sterols, phenols and amino-acids) and various other substances. The purity of this compounds is strongly connected to the state of the marine ecosystem. In the present paper are presented the main bioactive compounds existing in the chemical composition of the green algae in the Black Sea studied. The details of the therapeutic properties of the green algae generated by their chemical compositions.

The associations and ecological conditions of the existence of modern diatoms of the North-West (Pridneprovsky), Prikerchensky and Eastern regions of the subtidal zone of the Black Sea are considered. Based on the unity of the composition of the Present and Sarmatian-Meotian diatom flora, an attempt has been made to model some of the ecological c situation of the Late Miocene Euxinian basin.
