lingonberry (vaccinium vitis-idaea) and european cranberry (vaccinium microcarpon) proanthocyanidins: isolation, identification, and bioactivities.european, small-fruited cranberries (vaccinium microcarpon) and lingonberries (vaccinium vitis-idaea) were characterized for their phenolic compounds and tested for antioxidant, antimicrobial, antiadhesive, and antiinflammatory effects. the main phenolic compounds in both lingonberries and cranberries were proanthocyanidins comprising 63-71% of the total phenolic content, but anthocyanins, hydroxycinnamic acids, hydroxybenzoic acids, and flavonols were also found. proanthocyanidins are polymeric ...201121370878
characterization of in vitro antifungal activities of small and american cranberry (vaccinium oxycoccos l. and v. macrocarpon aiton) and lingonberry (vaccinium vitis-idaea l.) concentrates in sugar reduced fruit spreads.in this study, cranberry and lingonberry concentrates were added to commercial sugar-reduced fruit spreads (raspberry-aloe vera, strawberry-guava, and strawberry-lime), and tested for their antifungal activities. selected strains of the species absidia glauca, penicillium brevicompactum, saccharomyces cerevisiae and zygosaccharomyces bailii, as well as xerophilic environmental isolates of the genera penicillium and eurotium were used for challenge testing. initially, varying concentrations of sy ...201525868124
prevention of urinary tract infections with vaccinium products.cranberries exert a dose-dependent inhibition of the adherence of e. coli fimbriae to uroepithelial cells. this was demonstrated in vitro but also ex vivo in vitro with urine from cranberry consumers. the active principle has not been identified in detail but type-a proanthocyanidins (pac) play an important role in the mechanism of action. since the three species, american cranberry (vaccinium macrocarpon), european cranberry (vaccinium oxycoccus) and/or lingonberry (vaccinium vitis-idaea), have ...201423922238

enrichment culture and identification of endophytic methanotrophs isolated from peatland plants.aerobic methane-oxidizing bacteria (mob) are an environmentally significant group of microorganisms due to their role in the global carbon cycle. research conducted over the past few decades has increased the interest in discovering novel genera of methane-degrading bacteria, which efficiently utilize methane and decrease the global warming effect. moreover, methanotrophs have more promising applications in environmental bioengineering, biotechnology, and pharmacy. the investigations were undert ...201728275945
pollen dispersal and fruit production in vaccinium oxycoccos and comparison with its sympatric congener v. uliginosum.investigating plant-pollinator interactions and pollen dispersal are particularly relevant for understanding processes ensuring long-term viability of fragmented plant populations. pollen dispersal patterns may vary strongly, even between similar congeneric species, depending on the mating system, pollinator assemblages and floral traits. we investigated pollen dispersal and fruit production in a population of vaccinium oxycoccos, an insect-pollinated shrub, and compared the pollen dispersal pat ...201322823148
global change shifts vegetation and plant-parasite interactions in a boreal mire.the aim of this study was to detect vegetation change and to examine trophic interactions in a sphagnum-dominated mire in response to raised temperature and nitrogen (n) addition. a long-term global-change experiment was established in 1995, with monthly additions of n (30 kg x ha(-1) x yr(-1)) and sulfur (20 kg x ha(-1) x yr(-1)) during the vegetation period. mean air temperature was raised by 3.6 degrees c with warming chambers. vegetation responses were negligible for all treatments for the f ...200717479763
ozone effects on the ultrastructure of peatland plants: sphagnum mosses, vaccinium oxycoccus, andromeda polifolia and eriophorum vaginatum.ozone effects on peatland vegetation are poorly understood. since stress responses are often first visible in cell ultrastructure, electron microscopy was used to assess the sensitivity of common peatland plants to elevated ozone concentrations.200415333464
allozyme evidence for genetic autopolyploidy and high genetic diversity in tetraploid cranberry, vaccinium oxycoccos (ericaceae).polyploidy has been important in the evolution of angiosperms and may significantly affect population genetic diversity and structure. nineteen isoenzyme loci were studied in diploid and tetraploid populations of vaccinium oxycoccos (ericaceae), and the results are compared with data previously reported for the related v. macrocarpon. diploid v. oxycoccos and v. macrocarpon were readily discriminated based on their allozymic variation. no evidence for fixed heterozygosity was found in tetraploid ...200011118425

plant quality and local adaptation undermine relocation in a bog specialist butterfly.the butterfly boloria aquilonaris is a specialist of oligotrophic ecosystems. population viability analysis predicted the species to be stable in belgium and to collapse in the netherlands with reduced host plant quality expected to drive species decline in the latter. we tested this hypothesis by rearing b. aquilonaris caterpillars from belgian and dutch sites on host plants (the cranberry, vaccinium oxycoccos). dutch plant quality was lower than belgian one conferring lower caterpillar growth ...201223467336
phenolics and anthocyanins in berries of european cranberry and their antimicrobial activity.european cranberry is a berry plant rich in biologically active substances, making it valued by both the phyto-pharmaceutical and food industries. the aim of this study was to examine the accumulation of phenolic compounds and anthocyanins in berries of european cranberry and to assess their antibacterial activity. material and methods: different wild clones of european cranberry were investigated according to berry weight and the amounts of total phenolics and anthocyanins. anthocyanin profiles ...200920173403
ecosystems effects 25 years after chernobyl: pollinators, fruit set and recruitment.animals are assumed to play a key role in ecosystem functioning through their effects on seed set, seed consumption, seed dispersal, and maintenance of plant communities. however, there are no studies investigating the consequences of animal scarcity on seed set, seed consumption and seed dispersal at large geographical scales. we exploited the unprecedented scarcity of pollinating bumblebees and butterflies in the vicinity of chernobyl, ukraine, linked to the effects of radiation on pollinator ...201222707037
