Growth and bile salt hydrolase (BSH) activity of the isogenic Lactobacillus plantarum 80 (LP80) strains were studied in vitro . In pure culture experiments viability growth performance BSH - LP80 strain was negatively affected by presence conjugated salts. The wild type (WT) overproducing (pCBHl) did not show a die-off upon supplementation latter hydrolysed glyco-conjugated deoxycholate (GDCA) more readily than tauro-conjugated (TDCA), indicating substrate specificity enzyme. activities...
Exogenous plasmid isolation was used to assess the presence of mobilizing plasmids in several soils and activated sludges. Triparental matings were performed with Escherichia coli (a member γ subgroup Proteobacteria ) as donor an IncQ (pMOL155, containing heavy metal resistance genes czc : Co r , Zn Cd ), Alcaligenes eutrophus β recipient, indigenous microorganisms from soil sludge samples helper strains. We developed assay mobilization potential a ecosystem on basis number transconjugants...
Abstract This study reports the first detailed geochemical characterization of Kolumbo submarine volcano in order to investigate role source heterogeneity controlling variability within Santorini volcanic field central Aegean arc. Kolumbo, situated 15 km northeast Santorini, last erupted 1650 AD and is thus closely associated with system space time. Samples taken by remotely‐operated vehicle that were analyzed for major element, trace element Sr‐Nd‐Hf‐Pb isotope composition include...

Geochemical research into volcanic rocks often involves isotopic analysis of whole rock powders. The method Deniel and Pin (Anal. Chim. Acta, 2001, 426, 95–103) for simultaneous isolation strontium lead using extraction chromatography via Sr spec™ resin was therefore adapted a straightforward procedure Pb isotope ratio determination by multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS). main focus to reduce their rather extensive costly cleaning procedures columns...
Abstract Volcanic products from Methana, Santorini and Nisyros show mineralogical geochemical characteristics that can be linked to their differentiation at different crustal levels, varying sources of subducted sediments. The in the western part arc, where overriding plate is thicker, are affected by amphibole fractionation contamination. volcano, central located on an extensively thinned section plate; it shows high Y-contents, a-typical for average continental crust. Crustal contamination...
A multimethod approach using petrography and strontium (Sr) isotopic analysis was applied to determine the geological source of 17 marble artefacts from Roman town Ammaia (Portugal). All samples are calcitic, with dolomite, quartz muscovite as accessory minerals. The marbles characteristically medium‐grained a maximum grain size (MGS) between 0.98 mm 1.82 mm, have heteroblastic texture, curved embayed calcite boundaries. 87 Sr/ 86 Sr values leachates range 0.708488 0.708639. Comparison...
This paper discusses the challenges we have faced in past 2.5 years of field experiments trying to measure speed Enhanced Rock Weathering (ERW) agricultural settings for removing CO₂ from atmosphere. Traditional measurements that allow quantification carbon dioxide removal (CDR) laboratory ERW tests include chemical analyses leached out soil water and monitoring with electronic pH EC sensors. Unfortunately, application these methods on our has not given us any results, it seems may take...
