Avaliação da eficiência de Physcomitrium acutifolium broth. como fitorremediador de ferro in vitro

Abstract

Bryophyta superdivision is composed by liverworts, anthoceres and mosses. Many species of mosses are known to act as indicators of environmental pollution by heavy metals and in order to test this characteristic in the laboratory, plant tissue culture is essential as an important tool for understanding various plant responses to stress. For a better understanding of “metal” and “moss” issues, metadata documents and structures organizational data in a structured manner to minimize duplication of effort and facilitate data retention. Thus, the objectives were to conduct a metadata survey to explore the theme of correlation between moss and metals and to evaluate the role of the Physcomitrium acutifolium moss as an in vitro iron bioremediator. In the first paper, we searched for the words “moss metal” on the Web of Science, Google Scholar, and NCBI / PubMed platforms and we can conclude how recent the research involving moss and heavy metals is and give us an insight into the major scientific journals. who publish about the topic and which research platform is most appropriate. In the second, three replicates of three MS culture media with different Fe-EDTA concentrations were prepared, including one control with 27.8mg/L and three treatments with 50mg/L, 300mg/L and 600mg/L, and six gametophytes were cultured per treble. of the treatments. With the analysis, we can conclude that the physcomitrium acutifolium moss under iron stress acts as a good phytoremediator because it does not suffer significant changes. However, for its full effectiveness as a phytoremediator, further analysis of the amount of iron present in the medium and its absorption is necessary.
