Structural assessment of a historic timber roof frame and barrel vault bearing a fresco by V.V. Reiner above the staircase in the Palace of Czernin
Drdácký, Miloš ; Frankl, Jiří
The report presents description and results of a survey of the state and defects and failures of a roof framework and a wooden barrel vault bearing a fresco by V.V.Rainer. Special attention is devoted to biological degradation and damages. There are suggested measures fro restoration.
Biodegradation of TNT by .I.in vitro./I. cultivated plants: A model system for study of degradation processes
Nepovím, Aleš ; Hebner, A. ; Gert, A. ; Thomas, H. ; Vaněk, Tomáš
In vitro cultivated water plants - helophytes were used for removing of TNT from cultivation medium.
12th International Biodeterioration and Biodegradation Symposium
Macek, Tomáš ; Macková, M. ; Jenč, P. ; Demnerová, K.
The schedule of symposium is quite rich and includes sessions on a broad variety of related topics, ranging from biochemistry and genetics of biodegradation of organic compounds, issues of environmental toxicity, through construction of genetically modified organisms, to the biodegradation of cultural property.
Phytoremediation and biodegradation of PCB in soil
Ryšlavá, E. ; Krejčík, Zdeněk ; Macek, Tomáš ; Macková, M.
This is a part of the research work focused on study of possible mutual relationships of microorganisms and plants in PCBs metabolism. Polluted soil was obtained from a site which has been contaminated by PCBs for a long time. This soil was used for isolation of bacteria whixh potentially participate in biolodegradation of PCBs. The same contaminated soil was used for experiments under real conditions. Within six months three plant species were cultivated-tobaco (Nicotiana tabacum), black nighshade (Solanum nigrum) and alfalfa (Medicago sativa) - and decrease of PCBs was measured.
Bioavailability of PAH and its effects on biodegradation during composting
Cajthaml, Tomáš ; Hubálek, Tomáš ; Šašek, Václav
The publication deals with application of composting process on remediation of soils contaminated with PAHs. Bioavailability of PAHs was tested with sequential SFE and the data were compared with the results of remediation. SFE is suitable to predict results of bioremediation.
Studium metabolismu v rostlinách a jejich praktická aplikace při dekontaminaci životního prostředí
Nepovím, Aleš ; Podlipná, Radka ; Zeman, S. ; Jalový, Z. ; Gerth, A. ; Vaněk, Tomáš
A study of metabolism of TNT in plants was focused on degradation of 4-amino-2,6-dinitrotoluene (4-ADNT). Two plant species Senecio jacobea and Buphthalmum salicifolium cultivated under in vitro conditions in the presence of different concentration of 4-ADNT for 3 weeks
