Article
The present study aimed at creating a solid nanostructured scaffold suitable for the development of bacterial biofilms and that enabled bacteria to resist successfully to harsh nutritive and environmental conditions...
Article
Topography nanostructures have been extensively studied to reduce bacterial adhesion in medical, food and industrial contexts. Fibres have also been used in energy, water and wastewater treatments, and medical applications. Nanosized fibres, however, have rarely been analysed in interactions with bacteria, and they have always resulted as inhibitin...

Modern agriculture requires more efficient and low-impact products and formulations than traditional agrochemicals to improve crop yields. Iron is a micronutrient essential for plant growth and photosynthesis, but it is mostly present in insoluble forms in ecosystems so that it is often limiting for plants. This study was aimed at combining natural...
Article
Gas and volatile organic compounds (VOCs) release in soil is known to be linked to microbial activity and can differently affect the life of organisms in soil. Electronic noses (E-noses) are sensing devices composed of sensor arrays able to measure and monitor gases and VOCs in air. This is the first report on the use of such a sensing device to me...
Article
Phenanthrene is a hydrophobic organic pollutant, composed of three-fused benzene rings belonging to polycyclic aromatic hydrocarbons (PAHs). PAHs are produced by incomplete combustion of organic matter due to natural events, i.e. fires, and anthropogenic actions, i.e. C-containing fuels combustion. The presence of PAHs in contaminated soils is usua...

Chapter
Biological interactions in biosensors occur through different mechanisms, on the basis of the type of biological re-°ceptor elements employed therein that confer the biological specificity to the biosensors themselves (biocatalytic, biocomplexing or bioaffinity biosensors). The use of different transduction systems (amperometric, potentiometric, fi...

Conference Paper
Full-text available
To study and monitor environments, a plethora of sensors in last decades have been proposed and claimed to be as the most specific, sensitive, reliable, durable, affordable or whatever. However, they rarely take into account probable interactions of compounds of interest with other substances (i.e. molecules, matrices, surfaces, etc.) occurring in...

Soil is a complex ecosystem comprised of several and mutually interacting components, both abiotic (organo-mineral associations) and biotic (microbial and pedofaunal populations and plants), where a single parameter depends on other factors and affects the same and other factors, so that a network of influences among organisms coexists with the rec...

A hybrid electrospun nanofibrous framework of titania, generated at first by growing up the nanofibres directly onto an interdigitated electrode (IDE) as a transducer and then coating them with an ultra-thin film of PEDOT–PSS, was investigated as a potential sensing material for NO. The stoichiometric oxidation of NO into NO 2 by CrO 3 , allowed th...
Article
Electrospun nanofibres have been confirmed to be very good candidates for ultra-sensitive gas sensors since they greatly improve surface area to volume ratios of coatings, which in turn affect two additional and crucial features for sensors: high sensitivity and fast response time. Electrospinning is a simple method for the deposition of long (up t...

A microcosm was assembled to physically separate soil from roots and then it was used to study either the impact of living roots on soil-plant system during early stages of plant growth and its responses to abiotic stress. Oat (Avena sativa L.) seedlings were grown in the microcosm unit for 44-day. After 23 days from planting, 0.154 mg of CdSO4 wer...

Usually, ammonium in soil is carried out through steam distillation of ammonia obtained after alkalinization of soil extracts and further back titration of the collected solutions. Alternatively, ion selective electrodes (ISE) specific for ammonium ions can be used, in order to measure their concentration in aqueous soil extracts. The aim of this s...

Metalloporphyrins have been in use since a decade as sensitive layers for thickness shear mode resonator gas sensors. In spite of several successful demonstrations of sensitivity properties a complete comprehension of the sensing mechanisms is still far to be reached also if it is rather clear that metalloporphyrins molecular structure determines p...

Extracellular enzymes in soil often occur in immobilised forms, a state that may alter their interactions with substrates in comparison with enzymes in the solution phase. Sonication was evaluated for its usefulness in studying immobilised acid phosphatase by dispersing soil aggregates. Factors affecting soil dispersion during ultrasound applicatio...

Evolution of CO2 was measured during a 24 h CHCl3 fumigation at 25°C in eight different soils (CO2F) The cumulative production of such CO2 was always lower than that evolved under the same conditions by unfumigated soils (CO2NF). However, for five of the eight soils, CO2F accounted for more than 50% of CO2NF. Neither CO2F nor CO2NF were singl...

The presence of 1-N-acetylspermidine was revealed in root tissues of 2-d-old maize seedlings by inhibiting in vivo polyamine oxidase activity with acetylspermine added to the growth solution. The identity of 1-N-acetylspermidine was confirmed by HPLC-mass spectrometry. 14C-spermidine added to 1 mM spermidine in presence or absence of 1 mM acetylspe...

A stable acid phosphatase-polyresorcinol complex, retaining about 90% of the original enzymatic activity, was synthesized in the presence of peroxidase. The complex was disturbed by chaotropic agents, as 4 M urea, indicating that the enzyme linked the phenolic moiety by non-covalent bonds. The immobilized phosphatase was more stable than the free e...
