Abstract. Trinitrotoluene (TNT), a commonly used explosive for military and industrial applications, can cause serious environmental pollution. 28-day laboratory pot experiment was carried out applying bioaugmentation using laboratory selected bacterial strains as inoculum, biostimulation with molasses and cabbage leaf extract, and phytoremediation using rye and blue fenugreek to study the effect of these treatments on TNT removal and changes in soil microbial community responsible for contaminant degradation. Chemical analyses revealed significant decreases in TNT concentrations, including reduction of some of the TNT to its amino derivates during the 28-day tests. The combination of bioaugmentation-biostimulation approach coupled with rye cultivation had the most profound effect on TNT degradation. Although plants enhanced the total microbial community abundance, blue fenugreek cultivation did not significantly affect the TNT degradation rate. The results from molecular analyses suggested the survival and elevation of the introduced bacterial strains throughout the experiment. Keywords: TNT, bioaugmentation, biostimulation, phytoremediation, microbial community.

Straipsnis parengtas 2012 m. dr. Natalijai Juščenko dalyvaujant Lietuvos mokslo tarybos finansuojamos mokslo programos "Valstybė ir tauta: paveldas ir tapatumas" projekte "Klaipėdos kraš-to etnokonfesinio paveldo tyrimai, sukuriant geografinę informacinę sistemą" (2012-2014 m., Nr. VAT-12018). ABSTRACTModern information technologies (IT) provide progressive tools and methods for data collection, storage, processing, and publication. The essence of historical research is to synthesize new information from different types of historical sources. The analysis of scientific publications proved that IT are still rarely applied to historical research. Several reasons may account for the state of things. One of them is related to rather conservative attitudes of researchers in the field of IT towards collaboration, which also accounts for the absence of specialized software for historical research. The article introduces IT tools and methods which can be used in historical research in a popular way, and the authors expect to promote inter-disciplinarity in the field of history. KEY WORDS: necropolistics, geo-information system, data analysis. ANOTACIJAŠiuolaikinės informacinės technologijos (IT) suteikia pažangius duomenų kaupimo, saugojimo, apdorojimo ir pateikimo įrankius bei metodus. Istorinių tyrimų esmė yra naujos informacijos sintezė iš skirtingos prigimties istorinių šaltinių. Atlikta mokslinių publikacijų analizė rodo vis dar retą IT taikymą istorijos mokslo srityje. Įvardijamos kelios galimos tokios padėties priežastys -tai gana konservatyvūs IT ir istorijos srities mokslininkų požiūriai dėl galimo abipusio bendradarbiavimo, o tai lemia istoriniams tyrimams skirtos specializuotos programinės įrangos nebuvimą. Šiame straipsnyje pristatomi istoriniuose tyrimuose taikytini IT metodai ir įrankiai, siekiant paskatinti tarpdalykiškumą istorijos srityje. PAgRINDINIAI žODžIAI: nekropolistika, geoinformacinė sistema, duomenų analizė.
