These substances are pervasive pollutants introduced into the environment through anthropogenic and natural processes, causing ecological concerns and necessitating the quest for new strains capable of biodegrading these toxins. A novel strain of the genus <italic>Pseudomonas</italic> was isolated and molecularly identified based on partial 16S rRNA and phylogenetic analysis as <italic>Pseudomonas stutzeri</italic> strain BUK_BTEG1 from petrochemical contaminated soil. One factor at a time (OFAT) in Bushnell-Haas (BH) media was used to optimize the strain’s biodegradation conditions. The isolate could grow up to 600 mgL<sup>−1</sup> and 400 mgL<sup>−1</sup> of anthracene and phenanthrene as the sole carbon source at an optimum pH of 7.0 and 7.5 respectively, inoculum concentration of 4% (v/v), and temperature of 35°C during 72 hours of incubation. The strain could degrade phenanthrene and anthracene to a maximum of 99 and 72 percent, respectively, under ideal conditions. The breakdown products’ GC-MS analysis revealed the existence of the pathway’s main metabolites, catechol, salicylic acid, and derivatives of phthalic acid. The strain exhibits promising potential for use in the bio-cleansing of environments contaminated by PAHs.metabolites.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/abmj-2022-00082022-12-26T00:00:00.000+00:00Medicinal Plants from the Flora of Romania Beneficial in Osteoarthritis and Rheumatic Arthritishttps://sciendo.com/article/10.2478/abmj-2022-0010<abstract> <title style='display:none'>Abstract</title> <p>In this study, we focus on two arthritic diseases that affect a large part of the population, which cause inflammatory disorders of the joints and oxidative stress, which can cause certain degrees of disability. Arthritis is a chronic disease frequently encountered in the world’s population. Osteoarthritis, and rheumatoid arthritis, autoimmune and inflammatory conditions, are two extensive forms of arthritis associated with pain, swelling, and stiffness in the joints and a low standard of life. Many drugs are used in their treatment, associated with some severe side effects and expensive prices. Today there are many studies carried out with extracts from medicinal plants, used in alternative therapy, and effective in these diseases. They are available for clinical use due to the active phytoconstituents that modulate inflammation and are antioxidants. In carrying out this study, electronic databases were screened: Science Direct, PubMed, and Google Scholar, trying to describe these medicinal plants, and elucidate their biological mechanisms of action. The most numerous references were found on the following plants: <italic>Arctium lappa</italic>, <italic>Glycyrrhiza glabra, Nigella sativa, Urtica dioica,</italic> etc. vary parts of plants are used such as different types of seeds, roots, leaves, fruit, bark, flowers, or even the whole plant.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/abmj-2022-00102022-12-26T00:00:00.000+00:00Stimulation of Physiological Processes in St. John’s Wort ( L.)

These rhizobacteria bacteria are vital to the growth of plants and can serve as bio-fertilizer and can enhance food security through green agricultural practices. They exhibit special features which make them potential candidates as bio-fertilizer. Isolation and characterization of rhizobacteria is the first step toward their utilization as bio-fertilizers. Ten rhizobacteria from two different rice farms were isolated and characterized for plant growth promoting properties. The isolated rhizobacteria were identified morphologically, microscopically, biochemically, and molecularly. Plant’s growth promoting properties of these rhizobacteria was also analyzed which includes; Indole 3-acetic acid production (IAA), phosphate solubilisation, hydrogen cyanide production (HCN), ammonia production (NH<sub>3</sub>), and zinc solubilisation. Out of the ten isolates, three were found to have the best plant growth enhancing properties and were therefore the best candidates as bio-fertilizers. 16SrRNA study and phylogenetic analysis was performed in order to unravel the specie of these three isolates and they were identified as <italic>Bacillus subtilis</italic>, <italic>Bacillus niacini</italic>, and <italic>Bacillus cereus</italic> with accession numbers OM184294, OM1842295 and OM184296 respectively.

The goal of this investigation is to assess the pharmacological and phytochemical potentials of the grossly underexplored <italic>Antidesma montanum</italic> Blume (Family: Phyllanthaceae). The methanolic extract of the leave of this plant was fractionated and then followed by initial screening of phytochemical. The investigation of the pharmacological potential, which includes antioxidant, antidiarrheal, anti-inflammatory, analgesic, anti-pyretic, and anxiolytic evaluations, was accomplished using an <italic>in vitro</italic> free radical scavenging assay with 2,2-diphenyl-1-picrylhydrazyl (DPPH), castor oil-induced diarrheal test, egg albumin test, acetic acid-induced writhing model, brewer’s yeast induced fever test, swing test, open field, and light-dark test, respectively. The investigation o phytochemicals proposes that the methanol extract of <italic>A. montanum</italic> possesses flavonoids, tannins, terpenoids, saponins, amino acids, fixed oils, and sterols. Pharmacological evaluation suggests that <italic>A. montanum</italic> possesses significant antioxidant, anti-diarrheal, anti-inflammatory, and analgesic effects. The methanol and chloroform fractions exhibited better DPPH radical scavenging activities with an IC<sub>50</sub>: 103 ± 0.05 and 108.7 ± 0.05 µg/ml, respectively. The methanol and chloroform fractions also showed anti-inflammatory capacities in the egg albumin (IC<sub>50</sub> values: 89.10 ± 0.07 and 92.85 ± 0.07 µg/ml, respectively) model. The plant also showed anti-pyretic and anxiolytic activities in a dose-dependent manner. One of the possible sources of phytotherapeutic lead compounds is <italic>A. montanum</italic>.

One of the most widely used pesticides at a global level, glyphosate, has been controversial for many years and many studies have focused on the effects of this compound on human health. Ethephon is also a controversial ripening agent used to ripen crops more quickly. A basic but crucial step in the study of the effects of their use on human health is the development of adequate analytical methodologies for the quantification of the compounds in relevant samples. For this study a quick, simple and selective method which uses LC-MS/MS was developed for the determination of ethephon, glyphosate and AMPA. The method uses selective fragment monitoring for each analyte and the internal standard, without prior analytical separation. Mobile phase used consisted of aqueous ammonium formate and methanol in isocratic elution and the sample cleanup was made using solid phase extraction (SPE). The method was validated with regards to selectivity, sensitivity, accuracy and precision in accordance with applicable guidelines. After validation the LC-MS/MS method was successfully used to determine ethephon, glyphosate and AMPA residues in ground and surface water, as well as vegetable samples.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/abmj-2022-00052022-07-09T00:00:00.000+00:00The Herbarium Files of Gyula Erazmus Nyárády which Got Abroadhttps://sciendo.com/article/10.2478/abmj-2018-0011<abstract><title style='display:none'>Abstract</title><p>The herbarium of Gyula Erazmus Nyárády has been assessed to contain around 90.000 sheets.

These were seeded in a cadmium artificial contaminated environment with or without hemp shives. The efficiency of hemp shives as natural amendments was evaluated after 40 days of initiating experimental model, by evaluation of plant growth and development of plants through biometric and gravimetric measurements. Also, the concentration of assimilatory pigments was determined. In order to establish bioaccumulation capacity, degree of recovery and translocation factor, it was determined the concentration of cadmium metal ions absorbed in various parts of rapeseed and flax plants. It has been found that the development of the root system is more pronounced in the presence of hemp shives both in contamination with cadmium ions and in the absence. By determining cadmium concentrations accumulate in various parts of the plant have been shown that supplementing growth media with hemp shives, improves the bioaccumulation process of cadmium ions. According to the results, the hemp shives can be used as amendments in phytoremediation process, enhancing bioaccumulation process.</p></abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/abmj-2018-00122020-06-08T00:00:00.000+00:00Ferulic Acid – A Versatile Moleculehttps://sciendo.com/article/10.2478/abmj-2018-0013<abstract><title style='display:none'>Abstract</title><p>The review summarizes the main roles of ferulic acid (4-hydroxy-3-methoxy-cinnamic acid), a phenolic compound widespread in the vegetable world, being present in cereals (rice, wheat, oats), coffee, tomatoes, nuts or corn, but also in a range of plants used in Traditional Chinese Medicine. It plays a vital role in ensuring cell wall rigidity and also in the formation of other important organic compounds for plants. Ferulic acid has a wide variety of biological activities such as: antioxidant, anti-inflammatory, antimicrobial, antiallergic, anticancer, antithrombotic, antiviral activities, vasodilator, hepatoprotective and metal chelation actions, enzymatic activity modulation, and wound healing activity. The most important action is the antioxidant one, being studies that demonstrate that ferulic acid acts synergistically with other antioxidants. Also, the antioxidant effect of ferulic acid is enhanced by skin exposure to ultraviolet light, making it a good ingredient for sunscreen cosmetics. It is one of the most powerful natural antioxidant that has the potential to neutralize free radicals, to slow down the aging process of the skin, to accelerate skin regeneration, to heal the skin wounds and also to preserve the health and beauty of the skin.</p></abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/abmj-2018-00132020-06-08T00:00:00.000+00:00The Medicinal Importance of Wild Plants from the Surroundings of Ulieş Village, Mureş Countyhttps://sciendo.com/article/10.2478/abmj-2018-0010<abstract><title style='display:none'>Abstract</title><p>The village of Ulieş belongs to Râciu Commune.

Vegetation monitoring of Ethiopian Highlands requires visualization of environmental parameters to assess droughts negatively influencing agricultural sustainable management of crops. Therefore, this study presented mapping of several climate and environmental variables including Palmer Drought Severity Index (PDSI). The data were visualized and interpreted alongside the topographic data to evaluate the environmental conditions for vegetation. The datasets included WorldClim and GEBCO and Digital Chart of the World (DCW). Research has threefold objectives: i) environmental mapping; ii) technical cartographic scripting; iii) data processing. Following variables were visualized on seven new maps: 1) topography; 2) soil moisture; 3) T °C minimum; 4) T °C maximum; 5) Wind speed; 6) Precipitation; 7) Palmer Drought Severity Index (PDSI). New high-resolution thematic environmental maps are presented and the utility of GMT for mapping multi-source datasets is described. With varying degrees of soil moisture (mean value of 15.0), min T°C (−1.8°C to 24°C), max T°C (14.4°C to 40.2°C) and wind speed (0.1 to 6.1 m/s), the maps demonstrate the variability of the PDSI fields over the country area (from −11.7 to 2.3) induced by the complex sum of these variables and intensified by the topographic effects notable over the Ethiopian Highlands which can be used for vegetation analysis.
