    Opis:
    Background Drug-resistant bacteria are one of the main reasons of deaths worldwide. A significant group of these bacteria are carbapenemase producing Enterobacteriaceae (CPE). The goal of this study was to develop a diagnostic and therapeutic model targeted at asymptomatic carriers of CPE. Material and Methods A team of experts from different branches connected to health care, discussing the topic based on the data collected from previous research. Working sessions were dispersed between June and December 2022. The consensus has been reached via repeated discussion and literature search. Results The facility where CPE are detected is required to create an alert pathogen note and to notify sanitary-epidemiological station and National Reference Centre for Antimicrobial Susceptibility of Microorganisms – neither these institutions, nor the patient are required to notify the primary care physician. In primary care clinics, it is possible to work towards breaking the transmission of CPE by educating patients with CPE and persons who were in contact with them, and to undertake actions in order to look for patients with risk factors for CPE colonisation. In order to improve communication between individual levels of the health care system, standardised information could be introduced to the discharge note about a case of CPE, which will be electronically transmitted to the primary care facility. It might contribute to effective combating of the spread of CPE, by serving as a source of knowledge and education for patients and by checking the patient’s risk factors, which will improve the performance of tests for CPE colonisation. Conclusions The established model of good practice requires a change of legal regulations and its implementation, which will reduce the spread of CPE in health care facilities and will enable its future improvement.

    Opis:
    Nanocrystalline apatites Ca10(PO4)6(OH)2 (HAp) non-doped and doped with Ag+ and Eu3+ ions were synthesized by different wet chemistry methods. The obtained hydroxyapatite was loaded with Ag0, as well as nitroimidazole antimicrobials: metronidazole and tinidazole. The antimicrobial activity of the obtained materials against Prevotella bivia and Parabacteroides distasonis was studied. The method used for the antibacterial susceptibility testing was broth microdilution, according to the CLSI – Clinical and Laboratory Standard Institute – standard M11-A8; agar Schaedler, enriched with 50% LHB - Lysed Horse Blood, was used as a medium for culturing strains. The antibacterial activity increased for the immobilized antibiotics – HAp doped with metronidazole and tinidazole was six times more bactericidal than non-immobilised metronidazole for both clinical isolates. In comparison with non-immobilised tinidazole, HAp immobilised with tinidazole was six thousand times more effective against P. distasonis and two hundred times more effective against P. bivia. HAp doped with tetracycline was over two times more bactericidal than tetracycline non-immobilised (according to the literature data). The exact MIC for bionanocomposites of HAp and silver was not obtained. The research shows that bionanocomposites of hydroxyapatite are good drug carriers for both antibiotics and silver particles and ions. The use of bionanocomposites of apatite immobilised with antibiotics in dentistry could result in a prolonged antibacterial activity of these compounds.

    Opis:
    The presence of metals in waters represents today typical anthropogenic pollution. Their increased content, originating in various industry sectors and previous mining activity, is undesired. High concentrations of metals are hazardous for all living organisms. They may accumulate to toxic levels, cause many disorders and diseases and ecological damage under certain environmental conditions. Sulphate-reducing microbial process utilization is one of the options to prepare applicable sorbent which removes metal ions from solutions. This sorbent is created as a consequence of sulphate-reducing bacteria metabolism in anaerobic environment. It is considered to be able to remove many metals from solutions, such as Zn, Cd, Pb, Cu, Ni, As.
    Obecność metali w wodach stanowi obecnie typowe zanieczyszczenie antropogeniczne. Ich podwyższona zawartość, pochodząca z różnych sektorów przemysłu i wcześniejszej działalności górniczej są niepożądane. Wysokie stężenia metali są niebezpieczne dla wszystkich żywych organizmów. Zawartość metali przekraczająca poziom toksyczności powoduje wiele zaburzeń i chorób oraz szkód ekologicznych. Wdrożenie procesów mikrobiologicznych jest jedną z opcji przygotowania sorbentu do usuwania jonów metali z roztworów. Sorbent powstaje w wyniku metabolizmu bakterii redukujących siarczany w środowisku beztlenowym. Sorbent taki jest w stanie usunąć z roztworów takie metale jak Zn, Cd, Pb, Cu, Ni, As.

    Opis:
    The fiberglass pipes were used for transportation of water in order to maintain the pressure in the oil field of Zarzaïtine (Region of In Amenas located in the south of Algeria). During the maintenance work in summer, a season well known for its extensive heat, the deposits contained in the pipe, and after its contact with the atmosphere, have caused a smoke and it was followed by a fire that ignited a portion of the pipe. To give an answer to the causes of this phenomenon, we have first incriminated the role of specific bacterial species and therefore we have made a microbiological analysis of the deposits collected from the site of the incident. The obtained results revealed the presence of a heterogeneous microbial population with a high concentration level of sulfate-reducing bacteria (SRB), methanogenic bacteria (MB), yeasts and fungi. The interaction between the different species of bacteria and the organic matter contained in the deposits has generated the formation of methane which under the influence of the great heat burnt and the fire caused the ignition of the fiberglass line.

    Opis:
    The aim of the study was to assess the effect of silage additive containing heterofermentative lactic acid bacteria (LAB) strain of Lactobacillus buchneri species on ensiling quality, as well as methane yield and the kinetics of biogas production from ensiled perennial energy grasses: Miscanthus × giganteus (miscanthus), Spartina pectinata (cordgrass), Panicum virgatum (switchgrass) and Andropogon gerardii (big bluestem). The listed plants are not commonly used for biogas production, their susceptibility to ensiling is also little known, hence the need to investigate their suitability for these processes. Effective methods for increasing the biogas yield from biomass are still demand, hence the research on the use of LAB for this purpose. After harvesting the grasses were cut and ensiled in barrels with and without (controls) the usage of commercial silage inoculant containing Lactobacillus buchneri LN40177. After 90 days of ensiling obtained silages were analysed in order to compare their chemical composition: organic acids content, the loss of dry matter, the differences in particular fibres composition. The silages were then subjected to methane fermentation using OxiTop® sensors and exposed to air in order to check their aerobic stability. The silages prepared with LAB additive had higher concentration of acetic acid than the control silages prepared without LAB addition, which contributed to increased aerobic stability but had no effect on the methane yield of miscanthus, switchgrass and big bluestem. Using the microbial inoculant during ensiling had beneficial effect in terms of reducing the duration of biogas production process from obtained silages: lag phase was shortened, daily biogas production rate was increased and 90% of biogas was produced in a shorter period of time compared to the control silages from investigated grasses. The modified Gompertz model well reflected the kinetics of biogas production process.

    Opis:
    The objective of this study is to investigate biogas production by anaerobic digestion using mesophilic bacteria mixed with Palm Oil Mill Effluent (POME). This project aims to determine the volume of biogas generation and volatile fatty acid (VFA) production from chicken manure via the anaerobic digestion process. Anaerobic digestion (AD) of chicken manure (CM) often faces obstacles, including high total ammonia nitrogen (TAN) concentration, inorganic soil particles, and wood chips. The digestion process was carried under batch mode conditions in Scott bottles of 1.0 L active volume. The bottles were immersed in a water bath to control their temperature at 37℃. The characteristics of total solid, volatile solid of mass fraction, pH, and temperature on the amount of biogas produced were studied. The investigation showed that biogas production can be enhanced by inoculation of another material. The optimum biogas composition in the AD system was recorded by Inoculum I, which was achieved on Day 2 at 560 mL/L. The highest cumulative methane yield was observed in the leachate with Inoculum (I), which was 8976 mL/gVS, while the CML produced 4 mL/g VS. The anaerobic digestion (AD) process augmented with inoculum demonstrated heightened efficacy in biogas generation and VFA concentration reduction during the acidogenic phase, surpassing the observed performance in chicken manure leachate.

    Opis:
    Sulphidogenous microorganism communities were isolated from soil polluted by crude oil. The study was focused on determining the influence of 1) copper (II) concentration on the activity of selected microorganism communities and 2) the applied electron donor on the course and evolution of mineral-forming processes under conditions favouring growth of sulphate-reducing bacteria (SRB). The influence of copper concentration on the activity of selected microorganism communities and the type of mineral phases formed was determined during experiments in which copper (II) chloride at concentrations of 0.1, 0.2, 0.5 and 0.7 g/L was added to SRB cultures. The experiments were performed in two variants: with ethanol (4 g/L) or lactate (4 g/L) as the sole carbon source. In order to determine the taxonomic composition of the selected microorganism communities, the 16S rRNA method was used. Results of this analysis confirmed the presence of Desulfovibrio, Desulfohalobium, Desulfotalea, Thermotoga, Solibacter, Gramella, Anaeromyxobacter and Myxococcus sp. in the stationary cultures. The post-culture sediments contained covelline (CuS) and digenite (Cu9S5). Based on the results, it can be stated that the type of carbon source applied during incubation plays a crucial role in determining the mineral composition of the post-culture sediments. Thus, regardless of the amount of copper ion introduced to a culture with lactate as the sole carbon source, no copper sulphide was observed in the post-culture sediments. Cultures with ethanol as the sole carbon source, on the other hand, yielded covelline or digenite in all post-culture sediments.

    Iodinated contrast media compounds (ICM) have been identified in wastewater within the last 20 years. In this study, the biodiversity of activated sludge in anaerobic membrane bioreactors dealing with synthetic hospital wastewater with addition of ICM was investigated, using fluorescent in situ hybridization (FISH) and denaturing gradient gel electrophoresis (DGGE). During the adaptation of microorganisms to anaerobic growth conditions and to ICM presence, differences in the content of Alpha- and Betaproteobacteria were noted and bioreactors showed higher biological diversity (H = 2.9), suggesting that ICM were not toxic to the bacteria. The long sludge age had the strongest influence on the composition of activated sludge biocenosis.
