A lot of crops are destroyed by the phytopathogens such as fungi, bacteria, and yeast leading to economic losses to the farmers. Members of theBacillusgenus are considered as the factories for the production of biologically active molecules that are potential inhibitors of growth of phytopathogens. Plant diseases constitute an emerging threat to global food security. Many of the currently available antimicrobial agents for agriculture are highly toxic and nonbiodegradable and thus cause extended environmental pollution. Moreover, an increasing number of phytopathogens have developed resistance to antimicrobial agents. The lipopeptides have been tried as potent versatile weapons to deal with a variety of phytopathogens. All the three families ofBacilluslipopeptides, namely, Surfactins, Iturins and Fengycins, have been explored for their antagonistic activities towards a wide range of phytopathogens including bacteria, fungi, and oomycetes. Iturin and Fengycin have antifungal activities, while Surfactin has broad range of potent antibacterial activities and this has also been used as larvicidal agent. Interestingly, lipopeptides being the molecules of biological origin are environmentally acceptable.

Recently, the task of artificial cultivation of especially valuable fish species in aquaculture has become more and more urgent. The value of salmon fish, and in particular rainbow trout Oncorhynchus mykiss (Walbaum, 1792) available for breeding, is largely determined by the high content of biologically active essential and polyunsaturated fatty acids of the group ω-6 and ω-3, necessary for vital activity and not synthesized by the human body. Since the natural stocks of many popular fatty fish have decreased, farmed fish can help meet consumer demand for this product. Based on this, the assessment of the content of the main ω-6 and ω-3 fatty acids in the fat of rainbow trout grown in closed-loop water supply installations (USV) was made. The fat was extracted from the fish by thermal method with further distillation by supercritical fluid extraction on the SFT-150 unit. The ratio of fatty acids in the fish oil sample was determined using the Chromatek-Kristall-5000 M hardware and software complex. The results obtained were compared with the standard for salmon fish oil “Aquaculture products” and “Wild fish”. It is established that trout cultivated in the UZV in the Penza region, in terms of the content of the main essential fatty acids, is not inferior to the quality indicators of the standard in terms of the requirements for salmon fish of “Aquaculture products”. In fish, all essential fatty acids are present in sufficient quantities, the ratio of ω-6 to ω-3 is 2.6:1, which indicates a high nutritional value of the product and allows it to be used in human food to provide the body with essential fatty acids, as well as a raw material for obtaining therapeutic and preventive products.

Background: The composition and bioactivity of natural plant extracts strongly depend on the extraction technique employed. Clinacanthus nutans Lindau (C. nutans) is a well-known medicinal plant in South-East Asia that has been traditionally used for the treatment of various diseases. Several conventional methods have been using for extraction of bioactive compounds from C. nutans. However, extraction of fatty acids using supercritical carbon dioxide was not reported yet from this medicinal herbs. Objective: The main objective of the study is to examine the potential of supercritical carbon dioxide (scCO2) extraction of fatty acids from leaves and stems of C. nutans. Method: Fatty acid compositions were determined from leaves and stems of C. nutans oil extracted by scCO2 (temperature 45-65 °C, pressure 25-35 MPa), and compared to the results of Soxhlet extraction. Results: Supercritical CO2 extraction shows the highest oil recovery in both leaves (3.7%) and stems (1.6%) at pressure 35 MPa, temperature 65 °C and 2 ml/min flow rate, which was closer to the yield of Soxhlet. The scCO2 yields presented a higher percentage of polyunsaturated fatty acids (PUFA), especially linoleic acid (C18:2n-6). Palmitic acid ranging from 42%- 47% in leaves and stems of C. nutans was found dominant saturated fatty acids (SFA) in both scCO2 and Soxhlet method. Conclusion: The current results indicate that leaves and stems of C. nutans could be a potential source of fatty acids especially biologically active compounds.Conclusion: The current results indicate that leaves and stems of C. nutans could be a potential source of fatty acids especially biologically active compounds.

Introduction. Evaluation of high-quality composition and content of biologically active compounds of Salsola tragus grass as promising raw materials for the pharmaceutical industry. Aim. To determine the chemical composition of the above-ground part of the Black Sea species of S. tragus for the purpose of its use in medicine. Materials and Methods. The study of biologically active compounds S. tragus were conducted in the summer of 2020. Grass samples were collected along the field road near the coast of the Tiligul estuary. The above-ground biomass of this species was analysed. The total content of lipids and their fatty acid composition, the content of carbohydrates, phenolic compounds and their derivatives were studied by generally accepted methods. The acidity titre was determined using a solution of oxalic acid. Main results. 11 compounds of phenolic nature, among which 5 phenoloxides (ferulic, cinnamic, caffeic, gallic and chicoric), 1 coumarin (esculetin) and 5 flavonoids (quercetin, rutin, luteolin-7-glucoside, hyperoside, hesperedin) were identified and quantitatively determined. Ferulic and gallic acid prevail among phenolic acids. Among the flavonoids luteoline-7-glucoside and hesperedin prevailed. Grass S. tragus was quite rich on lipid components. In their composition, 8 fatty acids were found. The content was dominated by unsaturated fatty acids with the domination of linoleic and oleic acids – 27.67 and 19.27 % respectively. The largest content among the investigated biologically active compounds of S. tragus belongs to the total carbohydrates (8.31%). The titre of raw material was 1.8%. Conclusions. On the basis of a comprehensive study of biologically active compounds of grass S. Tragus it is possible to conclude that it can be used as a source of phenolic compounds, in particular flavonoids having a significant antioxidant, anti-inflammatory, antitumor, antimony activity, and oleic acid, which positively affects the exchange of cholesterol and essential fatty acids (ω-3 and ω-6) for the production of new phytomedications.

Docosahexaenoic acid (DHA) is one of essential fatty acids that are beneficial to health. Nowadays, the source of docosahexaenoic acid (DHA) is mainly obtained from fish which are extracted into fish oil products. However, the fish oil products still have some drawbacks in term of purity, acceptable flavor for costumers, and also their not environmental friendly production process. As an alternative solution, heterotrophic microalgae can be used as a potential source for DHA due to their excellence compared to fish oil products. The aim of this study is to isolate the heterotropic microalgae that can produce DHA. The heterotrophic microalgae were isolated from mangrove fallen leaves (Rhizophora apiculata) by using direct planting method. The morphology of pure microalgae colony were observed through light microscope and subsequently fermented for 14 days. Fatty acids were extracted and methylated through direct transesterification method. Identification and quantification of DHA were conducted by using gas chromatography. The results were four isolates of heterotropic microalgae, namely MTKC1, MTKC2, MTKC3, and MTKC4. The extract of MTKC2 that only showed the content of DHA with value of 9.2 % w/w. Therefore MTKC2 is a potential source for DHA. The MTKC2 was further identified by using molecular biology method and confirmed as Thraustochytrium aureum.

Global Food

The United Nation’s 2030 development agenda adopted in 2015 outlines 17 Sustainable Development Goals (SDGs), and the organization has continued to put food security in the center of its vocalization. Aquaculture is currently the fastest-growing food production sector globally and a sustainable option for attaining food security. Food as a basic necessity for man’s survival is always a timely issue. Hence, owing to aquaculture’s unique role, it is expected that the demand for aquatic products (especially seafood) will continue to increase due to geometric population growth. Many seafood products are among the critical protein sources in the world. This is partly because they have micronutrients and essential fatty acids that are not present in land-based protein sources. According to the Food and Agriculture Organization, shellfish is one of the main cultured aquaculture groups in the world. Hence, the development of shellfish aquaculture has an important role in sustainable food supply and food security. In this article, an overview of the current and projected contributions of shellfish aquaculture to global food security is presented. Apparently, shellfish aquaculture in the next few decades will have to be intensified to bridge the gap between demand and supply in a cost-effective manner. Also, food waste would have to be reduced and natural resources should be used more efficiently to minimize the negative impacts on aquaculture on the environment.
