Some trace elements in various lichens as biomonitors of pollution were investigated. Also, the pollution status was assessed by enrichment factor, contamination factor, and pollution load index. Investigated elements were Ta, Bi, Hf, Nb, Ga, Sc, Li, Y, Ce, and Sr. The lichen species were Rhizoplaca chrysoleuca, Umbilicaria vellea, Aspicilia calcarea, Pseudevernia furfuracea, and Cetraria islandica. According to the results, lichen species accumulate Sr element well. The highest trace element accumulated by Pseudevernia furfuracea (21.7±1.0 mg/kg; 75), Rhizoplaca chrysoleuca (31.9±1.6 mg/kg; 61), Umbilicaria vellea (16.3±0.8 mg/kg; . . .59), Aspicilia calcarea (77.9±3.8 mg/kg; 88), and Cetraria islandica (22.7±1.1 mg/kg; 75) was determined as Sr. The highest CFs in lichens investigated were calculated for Sr, Ta, and Li. PLI values for Cetraria islandica, Aspicilia calcarea, and Umbilicaria vellea were greater than 1. As a result, it has been proven that these lichen species can be used as good biomonitors of pollution. Keyword: accumulation; biomonitor; lichen; pollutio More less

There are mounting concerns over the high concentrations of non-biogenic, toxic halogenated organic compounds being liberated into the ecosystem. Therefore, this study’s isolation of a novel bacterium from a contaminated stream in Fatsa, Ordu, Turkey, adept in degrading 2,2-dichloropropionic (of 2,2-DCP) is a welcome endeavor. The ability of the bacterial isolate to utilize 2,2-DCP as the sole carbon and energy source was discovered when the bacterium was observed to grow well on liquid minimal media containing 20 mM of 2,2-DCP, showing a doubling time of 14.2 h. The following genetic and biochemical characterizations revealed that . . .the 16S rRNA sequence of the fatsa001strain is identical (99) to Pseudomonas fluorescence, after which the sequence was deposited in the NCBI GenBank as Pseudomonas sp. strain fatsa001 (MN098848). The halogen-degrading ability of the P. fluorescens fatsa001 bacterium was again confirmed by the PCR data, which showed the presence of a conserved group of amino acids from the group I dehalogenase gene. It worth mentioning here that this is the first report on a P. fluorescence bacterial strain with the ability to degrade toxic 2,2-DCP. The detoxification ability of this bacterium envisages its practicality as an in situ environmental bioremediation agent.

In this study, acetone and water extracts obtained from edible mushrooms, Rhizopogon luteolus Fr. and Rh. roseolus (Corda) Th. Fr., containing important bioactive components were used. Total antioxidant capacity (TAC) and total oxidative stress (TOS) levels were examined on human peripheral lymphocyte culture treated with the respective extracts. Levels of genetic damage and cytotoxic effects of the respective extracts on lymphocytes were also tested. In general, when TAC levels of the extracts on cells were examined, a concentration-dependent increase was observed; a negative correlation was found between TOS data and concentration . . .. Genotoxicity tests (chromosome aberration and micronucleus analysis) revealed that the concentrations of the extract applications did not significantly (P > 0.05) change genotoxicity on human peripheral lymphocyte culture compared to the negative control. Considering all of the results obtained, it was determined that applications of Rh. luteolus and Rh. roseolus extracts, especially at concentrations of 50 and 100 mg/L, increased the TAC value of lymphocytes, which play an important role in the human inunune system, without causing genetic or oxidative stress More less

Particle bombardment, or biolistics, has emerged as an excellent alternative approach for plant genetic transformation which circumvents the limitations of Agrobacterium-mediated genetic transformation. The method has no biological constraints and can transform a wide range of plant species. Besides, it has been the most efficient way to achieve organelle transformation (for both chloroplasts and mitochondria) so far. Along with the recent advances in genome editing technologies, conventional gene delivery tools are now being repurposed to deliver targeted gene editing reagents into the plants. One of the key advantages is that the . . .particle bombardment allows DNA-free gene editing of the genome. It enables the direct delivery of proteins, RNAs, and RNPs into plants. Owing to the versatility and wide-range applicability of the particle bombardment, it will likely remain one of the major genetic transformation methods in the future. This article provides an overview of the current status of particle bombardment technology and its applications in the field of plant research and biotechnology More less

Aspergillosis is a severe fungal disease that affects all species and ages of poultry and leads to significant economic losses within the poultry industry. The economic significance of aspergillosis is associated with direct losses due to poultry mortality, a decline in the production of meat and eggs, feed conversion, and poor growth of recovering poultry. Although a decrease in the production of poultry meat and eggs in Kazakhstan due to this fungal disease has been widely reported, studies on the consequent financial losses on affected farms (households) have not been carried out. This study aimed to estimate the financial losses . . . and epidemiological parameters of avian aspergillosis among households affected by the disease in the Almaty region. To achieve the objectives of the research, a survey was conducted involving affected households from February 2018 to July 2019. The affected poultry were diagnosed based on clinical, macroscopical, and microscopical procedures, and once the infection was confirmed, household owners were interviewed. Data were collected from 183 household owners. The median incidence risk and fatality rates were 39 and 26 in chickens, 42 and 22 in turkeys, and 37 and 33 in geese, respectively, with young poultry having a higher incidence risk and fatality rate than adults. Approximately 92.4 of the household owners treated the affected poultry using natural folk methods and 7.6 of household owners used antifungal drugs and antibiotics, spending a median of US 35.20 (min US 0; max US 400) per household throughout the course of the infection. Egg production was reduced by a median of 58.3 when households were affected. The price of poultry fell by a median of 48.6 immediately after recovery due to weight loss. The median of the overall financial losses of households was US 198.50 (min US 11; max US 1,269). The majority of household owners (65) did not replace their poultry, 9.8 of household owners replaced all their poultry, and the remaining 25.1 replaced only a proportion of the poultry lost at the time of the study. Newly acquired poultry were purchased from neighbors (10.9), fellow villagers (50), and state poultry farms (39.1). This study demonstrates that aspergillosis has an immediate impact on subsistence household owners' livelihoods in the Almaty region of Kazakhstan.

В статье представлены результаты работы по выявлению содержания тяжелых металлов в некоторых видах макромицетов, произрастающих на территории г. Бишкека, в различных по уровню техногенного загрязнения участках. Тяжелые металлы оказывают повреждающее действие на разных структурных уровнях организма и трудно выводятся, поэтому актуальной проблемой является поиск эффективных энтеросорбентов, способных снизить их аккумуляцию в организме человека. Такими свойствами обладают сорбенты из природных продуктов, среди которых особое место занимает полисахарид хитин, благодаря таким его уникальным свойствам, как биосовместимость, биодеградируем . . .ость, нетоксичность и бактерицидность. Исследования проводились в 2020-2021 гг. Анализы проводились химико-спектральным методом, который основан на полном испарении анализируемой пробы. Результаты анализов на содержание тяжелых металлов показали, что во всех указанных точках они выше от 23 % до 40 % по сравнению с контрольной точкой. Повышенное содержание тяжелых металлов по сравнению с контрольной группой объясняется антропогенным фактором и широким использованием их в электротехнике, в различных аккумуляторных соединениях. Содержание ртути превышает только в городской свалке Бишкека. Предметы, представляющие угрозу для окружающей среды и подлежащие утилизации, выносятся вместе с остальными More less
