Abstract Lactic acid is a biologically important organic acid existing in two enantiomeric forms which are differently metabolized in the human body. In this paper, direct chiral separation of lactic acid by high performance liquid chromatography is presented. Five chiral stationary phases based on macrocyclic antibiotics were used for enantioseparation and chromatographic parameters, such as retention factors, resolution and selectivity factors, were determined under different column temperatures ranging from 5 to 45 °C. Optical isomers of lactic acid were efficiently separated using chiral stationary phases based on teicoplanin (RS = 1.9 ) and ristocetin (RS = 1.7 ) in reversed-phase separation mode at the column temperature of 25 °C.
摘要乳酸是一种重要的生物有机酸,以两种对映体形式存在,在人体内代谢不同。本文采用高效液相色谱法直接分离乳酸。采用五种基于大环抗生素的手性固定相进行对映分离,并在5~45°C的不同柱温下测定了保留因子、分辨率和选择性因子等色谱参数。在25°C的柱温下,使用基于替考拉宁(RS=1.9)和利托西汀(RS=1.7)的手性固定相以反相分离模式有效分离乳酸的光学异构体。

Abstract The aim of the article was to investigate the effect of sea buckthorn juice addition on the growth of microbial cultures in growth medium and juice mixtures. Pure sea buckthorn juice was found to inhibit the growth of all 11 monitored microbial cultures. Lactobacillus plantarum CCM 7039, Lactobacillus plantarum K816, Lactobacillus brevis CCM 1815 and, to a lesser extent, the probiotic strain Lactobacillus rhamnosus GG, grew in a growth medium containing a 25 % addition of sea buckthorn juice. Lactobacillus plantarum K816 and Lactobacillus brevis CCM 1815 grew better in this mixture than in pure growth medium. Moreover, we focused on finding a suitable ratio of sea buckthorn and apple juice for Lactobacillus plantarum CCM 7039, leading to malolactic fermentation, which results in an increase in the pH value and an improvement in the sensory properties of juices. The intention was to incorporate the highest possible addition of sea buckthorn juice while maintaining the viability of Lactobacillus plantarum CCM 7039 for malolactic fermentation to occur. The best results were achieved using 40 % sea buckthorn juice. Practical application of the results points to the possibility of preparing a fermented fruit beverage and a dairy product containing sea buckthorn juice. The results of this work extend the current options of sea buckthorn juice processing increasing thus the consumption of healthy juice.
摘要本文研究了添加沙棘汁对培养基和混合果汁中微生物培养物生长的影响。发现纯沙棘汁抑制所有11种监测微生物培养物的生长。植物乳杆菌CCM 7039、植物乳杆菌K816、短乳杆菌CCM 1815以及鼠李糖乳杆菌GG在添加25%沙棘汁的培养基中生长。植物乳杆菌K816和短乳杆菌CCM 1815在混合培养基中生长较好。此外,我们重点寻找适合植物乳杆菌CCM 7039的沙棘和苹果汁的比例,进行苹果酸乳酸发酵,从而提高pH值,改善果汁的感官性能。目的是加入尽可能高的沙棘汁,同时保持植物乳杆菌CCM 7039的活力,使苹果酸乳酸发酵发生。沙棘汁用量为40%,效果最佳。结果的实际应用表明,可以制备含沙棘汁的发酵水果饮料和乳制品。这项工作的结果扩大了目前沙棘汁加工的选择,从而增加了健康果汁的消费。

Abstract The main topic of this study is to determine the effect of selected antibiotics on the respirometric activity of sewage sludge microorganisms. Within the practical part of the work, several respirometric measurements were performed with activated sludge from a wastewater treatment plant, while the influence of three selected antibiotics — sulfamethoxazole, sulfapyridine, and ciprofloxacin, on sludge activity was monitored. The aim of the work was to point out the inhibitory effect of all monitored compounds on sludge activity and to quantify the inhibitory effect. For sulfamethoxazole (in the concentration range of 0.142—1.42 mg·L−1), the determined inhibition was in the range of 9.67—27.7 %, depending on the concentration of the test substance and the type of respirometric measurements. For sulfapyridine, inhibition values ranged from 1.13 % to 31.9 % for the concentration range from 0.134 to 1.34 mg·L−1. Ciprofloxacin inhibited the activity of activated sludge microorganisms in the range of 4.55 % to 28.8 % (at CPX concentrations from 0.104 to 1.04 mg·L−1).
摘要本研究的主要课题是确定所选抗生素对污水污泥微生物呼吸学活性的影响。在实际工作中,对废水处理厂的活性污泥进行了几次呼吸测量,同时监测了三种选定的抗生素——磺胺甲恶唑、磺胺吡啶和环丙沙星对污泥活性的影响。这项工作的目的是指出所有监测化合物对污泥活性的抑制作用,并量化抑制作用。对于磺胺甲恶唑(浓度范围为0.142 ~ 1.42 mg·L−1),测定的抑制作用范围为9.67 ~ 27.7%,这取决于测试物质的浓度和呼吸测量的类型。对于磺胺吡啶,在0.134 ~ 1.34 mg·L−1的浓度范围内,抑制率为1.13% ~ 31.9%。环丙沙星对活性污泥微生物的抑制作用范围为4.55% ~ 28.8% (CPX浓度为0.104 ~ 1.04 mg·L−1)。

Abstract Novel technologies for organic pollutants degradation have been studied to cope with extensive water pollution. In this work, the use of ultraviolet degradation and potassium ferrate as possible oxidation tools for toluene, a widely used industrial chemical, degradation is proposed. In the experiment with ultraviolet irradiation, a low-pressure mercury lamp was used to generate a single line electromagnetic radiation with the wavelength of 254 nm. Maximal degradation efficiency achieved after 55 minutes of irradiation was 67.1 %. In the experiments with potassium ferrate, the highest degradation efficiency was 71.2 % at the concentration of 10 mg/L of ferrate (VI) anion.

Abstract This work aimed to determine the effect of packing density on the sublimation rate in a laboratory freeze dryer. Total amount of sublimed water was determined by gravimetric method while a total of seven experiments were performed under the same conditions (pressure, temperature, and drying time), at different configuration of the vials. The experiments confirmed that the higher the packing density, the lower the drying rate, and vice versa, the lower the packing density, the higher the drying rate. The effect of vials packing density was confirmed by experiments using a plastic rack, while the vials were separated and thus the packing density was lower. In this case, the drying rate was more homogeneous, which contributes to the higher quality of the final product.
本文旨在确定实验室冷冻干燥机中填料密度对升华速率的影响。通过重量法测定升华水的总量,同时在相同的条件(压力、温度和干燥时间)下,在不同的小瓶配置下进行总共七个实验。实验证实,填料密度越高,干燥速率越低,反之亦然,填料密度愈低,干燥速率愈高。小瓶包装密度的影响通过使用塑料支架的实验得到了证实,同时小瓶被分离,因此包装密度较低。在这种情况下,干燥速率更均匀,这有助于最终产品的更高质量。

Abstract Elevated cholesterol intake can induce the development of cardiovascular diseases in man, especially with long term animal origin foods consumption. Therefore, this work deals with the possibility of cholesterol content decrease in milk applying β-cyclodextrin crosslinked with tartaric acid (βCDcTA) as a removal agent. Evaluation of statistic data on food consumption in the Slovak Republic in 2018 aimed at total cholesterol daily intake and effects of “milky” cholesterol content decrease on total cholesterol balance. During the experiments, various amounts of βCDcTA addition to milk were studied resulting in optimal 5 % addition resulting in the cholesterol content decrease by 85.4 % in comparison to original cholesterol content. For monitoring purposes, an HPLC method analysing cholesterol content in saponified milk was employed. The food consumption data analysis showed that total per capita daily cholesterol intake was 369.8 mg, from which 86 mg was assigned to the cholesterol contained in milk and dairy products while the application of cholesterol removal procedure could decrease the total per capita daily cholesterol intake to 296.3 mg (“milky” cholesterol amount equal to 12.6 mg), which in below the recommended value of 300 mg daily intake still valid in the Slovak Republic. This approach might prove as a meaningful step to weaken health problems associated with high long term intake of cholesterol contained in foods of animal origin.
摘要胆固醇摄入增加会导致人类心血管疾病的发展,尤其是长期食用动物源性食物。因此,本工作探讨了用酒石酸交联的β-环糊精(βCDcTA)作为去除剂降低牛奶中胆固醇含量的可能性。评估斯洛伐克共和国2018年食品消费统计数据,旨在了解每日总胆固醇摄入量以及“乳白色”胆固醇含量下降对总胆固醇平衡的影响。在实验过程中,研究了在牛奶中添加不同量的βCDcTA,得出了5%的最佳添加量,与原始胆固醇含量相比,胆固醇含量降低了85.4%。为了监测目的,采用高效液相色谱法分析皂化乳中的胆固醇含量。食物消费数据分析显示,人均每日总胆固醇摄入量为369.8 mg,其中86 mg分配给牛奶和乳制品中所含的胆固醇,而应用胆固醇去除程序可以将人均每日总总胆固醇摄入量降至296.3 mg(“乳白色”胆固醇量等于12.6 mg),在斯洛伐克共和国,低于每天300毫克摄入量的推荐值仍然有效。这种方法可能被证明是一个有意义的步骤,可以减轻与动物源性食物中胆固醇长期摄入过高有关的健康问题。

Abstract A systematic study of (7,8-dimethylated) alloxazine, isoalloxazine, and their derivatives with substituted N(1) and N(10) positions was conducted using the density functional theory. The main aim of this work was the direct investigation of substituent effect on the molecular structure. Furthermore, HOMED aromaticity indices were calculated to describe the scope of the geometry changes. Frontier molecular orbitals of reference alloxazine, isoalloxazine and lumichrome derivatives were discussed by means of changes in their shape and energy levels. Photophysical properties were analyzed by determination of optical transition energies using the TD-DFT method. Obtained results were compared with previously published experimental data.

Abstract Increasing concentration of antibiotics in environment and their subinhibitory concentrations in wastewater may result in increased antibiotic resistance of present bacteria. Therefore, this study was aimed to analyze the efficiency of coagulase-positive staphylococci and Staphylococcus aureus inhibition in wastewater by electrochemical methods and addition of ferrates. Advanced electrochemical oxidation by boron doped diamond electrodes in anode; cathode and anode-cathode connection were used for wastewater disinfection. Results showed that the most effective connection was the anodic one, as complete inhibition of coagulase-positive staphylococci as well as of S. aureus was observed after 40 min. Energy consumption was 3.69 kWh/m3 for effluent wastewater disinfection. The second studied method of wastewater disinfection was the application of powdered ferrates. Addition of 100 mg of ferrates resulted in the inhibition of 84—96 % of coagulase-positive staphylococci and 97—99 % of S. aureus in influent water, while the inhibition of coagulase-positive staphylococci and S. aureus was 61—83 % and 83—86 %, respectively, in effluent wastewater.
摘要环境中抗生素浓度的增加及其在废水中的亚抑制浓度可能导致现有细菌的抗生素耐药性增加。因此,本研究旨在分析通过电化学方法和添加高铁酸盐对废水中凝固酶阳性葡萄球菌和金黄色葡萄球菌的抑制效果。硼掺杂金刚石电极在阳极中的高级电化学氧化;阴极和阳极-阴极连接用于废水消毒。结果表明,最有效的连接是阳极连接,因为40分钟后观察到对凝固酶阳性葡萄球菌和金黄色葡萄球菌的完全抑制。废水消毒的能耗为3.69kWh/m3。第二种研究的废水消毒方法是高铁酸盐粉末的应用。添加100mg高铁酸盐对进水中的凝固酶阳性葡萄球菌和金黄色葡萄球菌的抑制率分别为84~96%和97~99%,而对出水中的凝凝固酶阴性葡萄球菌和黄金黄色葡萄球菌分别为61~83%和83~86%。

Energy consumption was 3.69 kWh/m3 for effluent wastewater disinfection. The second studied method of wastewater disinfection was the application of powdered ferrates. Addition of 100 mg of ferrates resulted in the inhibition of 84—96 % of coagulase-positive staphylococci and 97—99 % of S. aureus in influent water, while the inhibition of coagulase-positive staphylococci and S. aureus was 61—83 % and 83—86 %, respectively, in effluent wastewater.","PeriodicalId":7088,"journal":{"name":"Acta Chimica Slovaca","volume":"13 1","pages":"49 - 54"},"PeriodicalIF":0.8,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49636607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract The ability of Trichoderma strains isolated from lignite and of Earth surface-derived strains to attack (solubilise) lignite, peat and wood was compared using glutamate as a carbon source. The results showed that lignite-derived microorganisms solubilise lignite to similar extent as Trichoderma strains isolated from the Earth surface. Solubilisation processes involve the action of enzymes and alkaline pH. The solubilisation of lignite was accompanied by a small increase of conidia-bound laccase, whereas that of peat was accompanied by (secretion) activity of cellulase, laminarinase, laccase, and lignin-peroxidase-like enzyme. In addition, data were obtained which show that bacteria contained in the lignite are able of lignite solubilisation and utilisation.
摘要以谷氨酸为碳源,比较了从褐煤中分离的木霉菌株和地表衍生菌株攻击(溶解)褐煤、泥炭和木材的能力。结果表明,褐煤来源的微生物溶解褐煤的程度与从地球表面分离的木霉菌株相似。溶解过程涉及酶和碱性pH的作用。褐煤的溶解伴随着与分生孢子结合的漆酶的少量增加,而泥炭的溶解则伴随着纤维素酶、昆布酶、漆酶和木质素过氧化物酶样酶的(分泌)活性。此外,获得的数据表明,褐煤中含有的细菌能够溶解和利用褐煤。

Abstract Antibiotic, soothing and healing properties of panthenol are exploited in various pharmaceutical and cosmetic products. Only D-panthenol is biologically active while its L-form might counteract the biological effectiveness of the D-enantiomer. Hydrating and moisturizing effects are exhibited by both enantiomers. Therefore, it is necessary to develop a rapid and cheap method for the determination of panthenol enantiomeric excess in pharmaceutical preparations. In this study, b-cyclodextrin was used as a chiral selector for the recognition of panthenol enantiomers. Inclusion complexes formed by b-cyclodextrin and the analyte showed small differences in NIR and UV/VIS spectra compared by chemometric assessment. Based on the figure of merit and model characteristics, PLS calibration model in the selected range of NIR spectra is preferred. UV/VIS spectrometry has the disadvantage of complicated sample preparation compared to NIR spectrometry. Results reached by both proposed methods were in good agreement. Statistical investigation of the results (by Student t-test and Fisher F-test) confirmed that the proposed methods are comparable and applicable to chiral analysis of panthenol pharmaceutical preparations.
泛醇具有抗菌、舒缓和愈合的特性,广泛应用于各种医药和化妆品中。只有D-蒽醇具有生物活性,而其L-形式可能抵消D-对映体的生物活性。两种对映体都具有保湿和保湿作用。因此,有必要开发一种快速、廉价的测定药物制剂中泛醇对映体过量的方法。在本研究中,β-环糊精被用作手性选择器来识别泛醇对映体。通过化学计量评估,b-环糊精和分析物形成的包合物在NIR和UV/VIS光谱中显示出较小的差异。基于优值和模型特性,优选在所选近红外光谱范围内的PLS校准模型。与近红外光谱法相比,紫外/可见光谱法具有样品制备复杂的缺点。两种方法得出的结果基本一致。对结果的统计调查(通过Student t检验和Fisher F检验)证实,所提出的方法具有可比性,适用于泛醇药物制剂的手性分析。
