| [functional properties of sphagnum magellanicum fiber and its direct use in formulation of bakery products]. | characterization of functional properties of sphagnum magellanicum fiber were investigated. water absortion (wac) and water retention (wrc) capacities, swelling capacity (sc); organic molecule absortion capacity (omac) and cationic interchange capacity (cic) were evaluated, as well as its incorporation as fiber source to bakery produts. diferent particles sizes were selected to evaluate their effects on the functional properties of moss fiber: t1(1.4 mm);t2(1.0 mm); t3(0.42 mm); t4(0.18 mm). bes ... | 2003 | 15125083 |
| investigations of the structure and function of bacterial communities associated with sphagnum mosses. | high acidity, low temperature and extremely low concentration of nutrients form sphagnum bogs into extreme habitats for organisms. little is known about the bacteria associated with living sphagnum plantlets, especially about their function for the host. therefore, we analysed the endo- and ectophytic bacterial populations associated with two widely distributed sphagnum species, sphagnum magellanicum and sphagnum fallax, by a multiphasic approach. the screening of 1222 isolates for antagonistic ... | 2007 | 17922763 |
| biological properties of the chilean native moss sphagnum magellanicum. | an ethanol extract prepared from the gametophyte chilean native moss sphagnum magellanicum was dried out, weighed and dissolved in distilled water. this extract was then assayed for its antibacterial activity against the g(-) bacteria azotobacter vinelandii, erwinia carotovora subsp. carotovora, enterobacter aerogenes, escherichia coli, pseudomonas aeruginosa, salmonella typhi, vibrio cholerae, and the g(+) bacteria staphylococcus aureus subsp. aureus, and streptococcus type beta. the growth of ... | 2009 | 19746269 |
| direct and interaction-mediated effects of environmental changes on peatland bryophytes. | ecosystem processes of northern peatlands are largely governed by the vitality and species composition in the bryophyte layer, and may be affected by global warming and eutrophication. in a factorial experiment in northeast china, we tested the effects of raised levels of nitrogen (0, 1 and 2 g m(-2) year(-1)), phosphorus (0, 0.1 and 0.2 g m(-2) year(-1)) and temperature (ambient and +3°c) on polytrichum strictum, sphagnum magellanicum and s. palustre, to see if the effects could be altered by i ... | 2010 | 21170747 |
| discovery of polyesterases from moss-associated microorganisms. | the growing pollution of the environment with plastic debris is a global threat which urgently requires biotechnological solutions. enzymatic recycling not only prevents pollution but also would allow recovery of valuable building blocks. therefore, we explored the existence of microbial polyesterases in microbial communities associated with the sphagnum magellanicum moss, a key species within unexploited bog ecosystems. this resulted in the identification of six novel esterases, which were isol ... | 2017 | 27940546 |
| [chemical-nutritional characterization of the moss spagnum magellanicum]. | the goal of the present study was to know the chemical characteristics of the moss sphagnum magellanicum (s.m.) growing in the southern part of chile, spreading approximately. in a geographic area of 500.000 has. very few antecedents are reported in the literature concerning the functional properties of this resource, with the exception of the water absorption and holding capacity. many of the industrial or agricultural uses of this moss are strongly related with this characteristic. looking for ... | 2002 | 12868281 |
| [multiplication of mycobacteria in the gray layer of sphagnum vegetation (author's transl)]. | the capillary moisture of the gray layer of the sphagnum magellanicum ass. contains nutrients for the growth of mycobacteria. tested in vitro significant multiplication was stated in m. intracellulare, serotyp davis, m. avium, m. scrofulaceum, m. fortuitum, m. xenopi, m. kansasii, m. borstelense, m. flavescens, m. gaxtri, m. gordonae, m. marinum, m. terrae, m. smegmatis, m. spec. "s" and m. nonchromogenicum (fig. 1 and 2). there was no evident multiplication in m. phlei, m. triviale, m. tubercul ... | 1978 | 566010 |
| swift recovery of sphagnum nutrient concentrations after excess supply. | although numerous studies have addressed the effects of increased n deposition on nutrient-poor environments such as raised bogs, few studies have dealt with to what extent, and on what time-scale, reductions in atmospheric n supply would lead to recovery of the ecosystems in question. since a considerable part of the negative effects of elevated n deposition on raised bogs can be related to an imbalance in tissue nutrient concentrations of the dominant peat-former sphagnum, changes in sphagnum ... | 2008 | 18465147 |
| [coarse woody debris loading capacity and its environmental gradient in huzhong forest area of great xing' an mountains]. | the coarse woody debris (cwd) loading capacity of main forest types and of different larch forest communities in huzhong area of great xing'an mountains was investigated, with its environmental gradient analyzed by detrended canonical correspondence analysis (dcca). the cwd loading capacity varied significantly with forest type, being the highest (0.20 m3 x hm(-2)) in spruce forest (picea koraiensis). different larch forest (larix gmelinii) communities had a cwd loading capacity from 0 to 0.28 m ... | 2009 | 19565754 |
| high specificity but contrasting biodiversity of sphagnum-associated bacterial and plant communities in bog ecosystems independent of the geographical region. | mosses represent ecological niches that harbor a hitherto largely uncharacterized microbial diversity. to investigate which factors affect the biodiversity of bryophyte-associated bacteria, we analyzed the bacterial communities associated with two moss species, which exhibit different ecological behaviors and importance in bog ecosystems, sphagnum magellanicum and sphagnum fallax, from six temperate and boreal bogs in germany and norway. furthermore, their surrounding plant communities were stud ... | 2007 | 18043652 |
