Authors: Rozali Zalniati Fonna
Published: August 2024

Pati resisten merupakan salah satu jenis karbohidrat dan termasuk dalam bahan baku atau  ingredien pangan fungsional yang berperan dalam meningkatkan kesehatan pencernaan. Berbeda dengan pati, pati resisten tidak dapat dihidrolisis menjadi glukosa oleh enzim amilase di usus kecil, namun dapat berperan sebagai serat pangan yaitu menjadi substrat dan difermentasi oleh beberapa bakteri sakarolitik di kolon. Hasil utama fermentasi berupa asam lemak rantai pendek (SCFA) seperti asam asetat, asam propionat dan asam butirat. Fermentasi utama pati resisten dilakukan oleh mikroflora kolon golongan sakarolitik. Sifat fungsional pati resisten sering dikaitkan dengan beberapa efek metabolik SCFA pada rasio tertentu dalam saluran pencernaan yang manfaat bagi kesehatan, seperti meningkatkan kekebalan tubuh, mengurangi peradangan, dan meningkatkan penyerapan nutrisi. Tinjauan literatur ini bertujuan untuk menyajikan penelitian yang relevan tentang peranan pati resisten sebagai substrat bagi bakteri sakarolitik dalam produksi SCFA di dalam kolon.

In recent years the growing demand for food led to intensification of agricultural practices, especially by the excessive use of fertilizers, which increased the environmental pollution. Therefore, pollution control by improving the efficiency of fertilizers and reducing their application is of great interest. Urease is one of the most active hydrolases in soil, having an important role in soil N cycle and being used as an indicator of soil quality. The objective of this study was to assess the urease activity in soils with different fertilization treatment, as well as its kinetic and thermodynamic parameters to better understand its driving factors. The results show a better enzymatic activity in soils treated with combined manure and mineral fertilizers. Soil urease has two optimal pH values, in the neutral and basic domains. Enzymatic activity has a steep increase with the temperature in the interval 45–65°C. The KM values increase with temperature from 11 to 23.5 mM, indicating a lower substrate affinity. The activation enthalpies for enzyme-substrate formation as well as for the rate limiting step are 7.59 and 14.18 kcal/mol respectively. The relationship between urease activity and microbial biomass will be further investigated.

В России геоконтейнерная технология обезвоживания впервые была применена для очистки озерных донных отложений от нефтяного загрязнения в 2013 г. в Западной Сибири, ХМАО-ЮГРА. Физико-химические и биологические исследования очищенных проб грунта из геоконтейнеров показали, что содержание нефтепродуктов в них снизилось на 80,6%-97,5%, ароматических углеводородов на 64,6%-92,5%, а содержание смолисто-асфальтеновой фракции на 45,2%-77,1% по сравнению с исходным загрязнением. Грунты из геоконтейнеров обогатились разнообразными видами микроорганизмов, в том числе способными фиксировать азот из воздуха. Концентрации аммонийного азота и растворимых фосфатов повысились в 2 и 1,5 раза, соответственно. В грунтах из геоконтейнеров отсутствовала фитотоксичность и наблюдалась в 3-6 раз более высокая биологическая активность по сравнению с исходными озерными донными отложениями, загрязненными нефтью. Примененная технология вполне пригодна для использования ее в качестве технологии очистки грунтов от нефтяного загрязнения, а также для снижения их фитотоксичности.

Abstract - A geotube dehydrating technology was used to purify limnetic bottom sediments from oil pollution for the first time in the Russian Federation in Western Siberia (Yugra, Khanty-Mansiysk Autonomous District) in 2013. Physicochemical and biological studies of purified soil samples from geotubes revealed decrease in the content of oil products by 80.6%-97.5%, aromatic hydrocarbons by 64.6%-2.5%, and tar-asphaltene fraction by 45.2%-77.1% as compared to the initial polluted samples. Soils from geotubes were found to be enriched in various kinds of microorganisms, including those capable of fixing nitrogen from the air. A 2-fold and 1.5-fold increase was found in concentrations of ammonium nitrogen and soluble phosphates, respectively. Phytotoxicity was not observed in the soils from geotubes, furthermore, a 3-6 fold increase of biological activity was also discovered as compared to the initial oil-polluted limnetic bottom sediments. Consequently, the geotube technology can be successfully applied for cleaning soils from oil pollution, as well as for reducing their phytotoxicity.

Метод молекулярно-пучковой масс-спектрометрии был применен к исследованию дихлоруксусной кислоты (ДХК) с использованием конкурирующих реакций. Уточнен масс-спектр кислоты, который оказался свободен от ионов молекул, образовавшихся при пиролизе ДХК на стенках ионного источника. На основе изучения кинетики реакции атомов фтора с ДХК и циклогексана, впервые рассчитана константа скорости реакции дихлоруксусной кислоты с атомарным фтором. Создан надежный источник радикалов CHClCOO и CHClCOO с целью исследования их реакций с атмосферным кислородом. Полученные результаты дают возможность установить процессы трансформации хлоруксусных кислот в атмосфере.

Abstract - Dichloroacetic acid (DCA) was studied by means of molecular beam mass spectrometry using the method of competitive reactions. The mass spectrum of the acid was defined more precisely and was found to be free of ions of the molecules formed during the pyrolysis of DCA on the walls of ion source. Kinetics studies for the reactions of fluorine atoms with DCA and cycloxehane resulted in calculating the rate constant for the reaction of interaction of DCA with atomic fluorine for the first time. A reliable source of radicals CH2ClCOO and CHCl2COO was created for examining their reactions with atmospheric oxygen. The results obtained make it possible to establish transformation processes of chloroacetic acids in the atmosphere.

Аннотация - В работе представлены результаты исследований структуры и физических характеристик наночастиц никеля, нанесенных на подложки графита, кремния, алюминия и титана, а также адсорбционные свойства наночастиц по отношению к водороду и воде. Свойства наноструктурированных систем изучались методами сканирующей туннельной микроскопии и спектроскопии. Показано, что такие физические параметры наночастиц, как форма и размер, практически не зависят от природы подложки, в то время как она оказывает существенное влияние на адсорбционные процессы.

Abstract - The paper presents results of studying structural and physical characteristics of nickel nanoparticles deposited on supports of graphite, silicon, aluminum, and titanium. Adsorption properties of the nanostructured compositions have been investigated with respect to hydrogen and water molecules. Properties of the nanostructured systems have been examined by scanning tunneling microscopy and spectroscopy. The study has found that shape and size of nanoparticles are practically not affected by nature of support, while a significant impact of support has been revealed for adsorption properties, apparently due to an excessive charge of the nanoparticles. The adsorption results for H2O molecules correlate with the charge sign of the nanoparticles due to the effects associated with the orientation of the H2O dipole molecules. The adsorption of the non-polar hydrogen molecule is not influenced by the charge sign, but correlates with the total value of the resulting excessive charge of the nickel nanoparticles. The results obtained contribute to characterization of nickel-based nanoparticles, which are not only an object of increased interest from basic science, but are already being used in environmental monitoring systems providing leakage control for a variety of hazardous substances in industry.

Результаты этих исследований апробированы на модели скрининговой оценки риска для здоровья населения диоксинов, загрязняющих среду селитебных зон в окрестностях свалки «Саларьево» в Новой Москве. Научная значимость работы отвечает задаче преодоления так называемых больших вызовов, принятых в качестве стратегического ориентира научно-технического развития Российской Федерации.

Abstract - The data obtained by the authors in their own long-term investigations of an ecologically-dependent pathology emerged among the population of Vietnam as a result of applying dioxin-contaminated Agent Orange by the US Army between 1962 and 1971, were systematized and used for addressing a problem of low dose toxicometry of dioxins and their prolonged chronic effects on mammals and humans. The prospects for extending the above scientific research data to public health hazards in Russia were demonstrated in screening evaluation study of an ecotoxicological situation observed in the residential areas located in the vicinity of a municipal solid waste landfill (Salariyevo, New Moscow). These data provide a basis for creating a new approach for identifying disadvantaged areas polluted with dioxins. The scientific relevance of the studies is consistent with a task of overcoming the so-termed big challenges taken as strategic guidelines for scientific and technological development of the Russian Federation.
