The aim of this study was to assess the chemical composition, antioxidant, antimicrobial and antibiofilm activity Coriandrum sativum essential oil. Changes in biofilm profile Stenotropomonas maltophilia Bacillus subtilis were studied using MALDI-TOF MS Biotyper on glass wooden surfaces. molecular differences biofilms different days observed as well. major volatile compounds coriander oil present β-linalool 66.07%. Coriander radical scavenging 51.05% inhibition. expressed strongest...
The aim of this study was to characterize extracts from the leaves Ginkgo biloba L. selected Slovakian localities in terms content bioactive constituents, antioxidants and their antimicrobial properties. results indicated that sample-specific, specificity statistically significant. locality Košice had best activity determined by free radical scavenging (DPPH) (1.545 mg Trolox equivalent antioxidant capacity (TEAC)/g fresh matter (FM)) as well molybdenum-reducing power (35.485 TEAC/g FM)...
The main aim of the study was to investigate chemical composition, antioxidant, antimicrobial, and antibiofilm activity
Abstract This study was designed to investigate chemical and antioxidant properties, as well the antimicrobial antibiofilm behaviour of Cinnamomum cassia essential oil (CCEO). MALDI-TOF MS Biotyper mass spectrometry applied evaluate biofilms Stenotrophonomonas maltophilia Bacillus subtilis , while ability CCEO assessed on wooden glass surfaces. The activity by disc diffusion method, microdilution vapour phase for two biofilm-producing bacteria three Penicillium spp. were used. Antimicrobial...
Buckwheat is one of the plant that possess a high nutrient benefits when used as human food. Up to now, different DNA markers were describe intra- and interspecie variability this plants. Here, BBAP (Bet v 1 amplified polymorphism), PBAP (Profilin based polymorphism) VBAP (Vicilin polymor-phism) methods applied analyse their ability distinguish varieties genotypes Fagopyrum esculentum Moench tataricum Gaertn. For all them, polymorphic profiles obtained with diversity index ranged from 0.87 u...
The studies of plant bacterial endophytes, colonizing the tissues without any signs diseases, are essential for understanding ecological interactions. aim our study is to detect microbiological contamination and assess antimicrobial, antioxidant activity, total phenolic, carotenoid content, genome size, ploidy non-cultivated Rosa canina sampled from urban areas. Samples fruits were collected in three locations Slovakia. highest viable count Enterobacteriaceae 4.32 log CFU/g 4.29 CFU/g,...
Staphylococcus spp. is not only a commensal bacteria but also major human pathogen that causes wide range of clinical infections. Recent evidence suggests has the ability to colonize reproductive system and affect its structure functions. The objective this study was determine chemical properties antibacterial effects select essential oils (EOs): Amyris balsamifera L., Boswellia carterii Birdw., Canarium luzonicum (Blume) A. Gray, Cinnamomum camphora (L.) J. Presl., var. linaloolifera Y....
Although bacterial contamination of ejaculates may cause difficulties in cattle reproduction, standard protocols for a routine microbiological analysis bovine semen are still missing. Understanding the mechanisms damage to spermatozoa contribute prevention and management bacteriospermia future. Therefore, this study was designed investigate profiles fresh (n = 30), while at same time we focused on assessing relationships between selected sperm quality parameters as well an array oxidative...
Endophytic bacteria are an important part of different functions in plants that lead to plants' production characteristics as well their stress response mechanisms. bacterial diversity was analyzed this study describe 16S rRNA variability and changes the leaves drought-tolerant drought-susceptible wheat when growth under vitro conditions. A metagenomic analysis applied a pilot exploratory performed prove type applicable tracking endophytic drought is culture wheat. The showed endophytes'...
This study focused on the identification of bacterial profiles semen in normozoospermic men and their possible involvement changes to sperm structural integrity functional activity. Furthermore, we studied fluctuations selected cytokines, oxidative markers, antibacterial proteins as a result presence ejaculate. Sperm motility was assessed with computer-assisted analysis, while apoptosis, necrosis acrosome were examined fluorescent methods. Reactive oxygen species (ROS) generation quantified...
The aim of study was to isolate and identify the gut bacteria Apis mellifera evaluate antagonistic effect bacteriota against Paenibacillus larvae, which causes American foulbrood (AFB) in honeybees. dilution plating method used for quantification selected microbial groups from digestive tract bees, with an emphasis on bees’ intestines. Bacteria were identified using mass spectrometry (MALDI-TOF-MS Biotyper). Overall, five classes, 27 genera 66 species identified. Genera Lactobacillus (10...
This study was designed to describe bacterial profiles of ejaculates collected following a long and short ejaculatory abstinence set in the context changes conventional, oxidative, immunological characteristics semen. Two specimens were succession from normozoospermic men (n = 51) 2 days h, respectively. Semen samples processed analyzed according World Health Organization (WHO) 2021 guidelines. Afterwards, sperm DNA fragmentation, mitochondrial function, levels reactive oxygen species (ROS),...
Melissa officinalis L., a well-known herb with diverse industrial and ethnopharmacological properties. Although, there has been significant lack in the breeding attempts of this invaluable herb. This study aimed to enhance agronomical traits M. through vitro polyploidization. Nodal segments were micropropagated subjected oryzalin treatment at concentrations 20, 40, 60 mM for 24 48 hours. Flow cytometry, chromosome counting, stomatal characteristics employed confirm ploidy level surviving...
Bacterial contamination of semen is an often overlooked, yet important, factor contributing to decreased sperm vitality. Understanding the impact bacterial presence on structural integrity and functional activity may assist development effective strategies prevent, or manage, bacteriospermia in breeding practice. The aim this study was describe profiles ram (n = 35), we also focused associations between bacteriospermia, structure, function, as well oxidative inflammatory characteristics...
The objective of the current study was to assess efficiency oryzalin in inducing polyploids Callisia fragrans (Lindl.) Woodson by vitro polyploidization. Shoot tips were subjected Murashige and Skoog (MS) medium containing at concentrations 1, 5, 10 μM for 4 8 weeks. Further, ploidy levels plants confirmed using flow cytometry chromosome counting. Among all treatments, six tetraploid (2n = 4x 24) obtained after weeks MS 5 oryzalin. Upon ex transfer, morphologically distinct compared diploid...
Sorghum is one of the most important cereal crop and ranks fifth among cereals after wheat, rice, maize barley for economic importance. Because demand food increasing, sorghum will increase in importance as a source food, feed, fibre, fuel; specially European continent where little cultivated, mainly due to lack varieties well adapted soil climate conditions such photoperiod, cold drought; this reason, genetic diversity analysis, through molecular characterization, an requirement begin plant...
The aim of the present study was to identify yeasts in grape, new wine “federweisser” and unfiltered samples. A total amount 30 grapes, samples (15 white 15 red) were collected from August until September, 2018, a local Slovak winemaker, including Green Veltliner (3), Mūller Thurgau Palava Rhein Riesling Sauvignon Blanc Alibernet André Blue Frankish Cabernet Dornfelder (3) grapes; federweisser also used our study. Wort agar (WA), yeast extract peptone dextrose (YPDA), malt (MEA) Sabouraud...
Bacterial contamination of semen is an important factor connected to the health status bulls that may significantly affect quality for artificial insemination. Moreover, some bovine diseases be transmitted through semen. Up now, only a very limited number complex studies describing microbiome have been published, as many bacteria are hard cultivate using traditional techniques. The 16S rRNA high-throughput sequencing strategy allows reliable identification bacterial profiles together with...
