AB  - Duckweed (L. minor) is a cosmopolitan aquatic plant of simplified morphology and rapid vegetative reproduction. In this study, an H. paralvei bacterial strain and its influence on the antioxida-tive response of the duckweeds to phenol, a recalcitrant environmental pollutant, were investigated. Sterile duckweed cultures were inoculated with H. paralvei in vitro and cultivated in the presence or absence of phenol (500 mg L−1 ), in order to investigate bacterial effects on plant oxidative stress during 5 days. Total soluble proteins, guaiacol peroxidase expression, concentration of hydrogen peroxide and malondialdehyde as well as the total ascorbic acid of the plants were monitored. Moreover, bacterial production of indole-3-acetic acid (IAA) was measured in order to investigate H. paralvei’s influence on plant growth. In general, the addition of phenol elevated all biochemical parameters in L. minor except AsA and total soluble proteins. Phenol as well as bacteria influenced the expression of guaiacol peroxidase. Different isoforms were associated with phenol compared to isoforms expressed in phenol-free medium. Considering that duckweeds showed increased antioxidative parameters in the presence of phenol, it can be assumed that the measured parameters might be involved in the plant’s defense system. H. paralvei is an IAA producer and its presence in the rhizosphere of duckweeds decreased the oxidative stress of the plants, which can be taken as evidence that this bacterial strain acts protectively on the plants during phenol exposure.

AB  - Niobium and aluminium were electrodeposited at 200 °C under argon
atmosphere onto vitreous carbon from inorganic chloroaluminate melts (AlCl3+NaCl)
with added niobium. Niobium was introduced into the electrolyte by anodic dissolution
of metallic niobium or by chemical dissolution of Nb2O5 in a melt of equimolar
AlCl3+NaCl mixture. The processes of deposition/dissolution onto/from vitreous carbon
were investigated by cyclic voltammetry and chronoamperometry. Characterization of
the obtained deposits was done by Scanning Electron Microscopy (SEM) and Energy
Dispersive Spectroscopy (EDS). The only observed reduction processes on the working
electrode in the potential window from 1.000 V to – 1.000 V vs. Al, were individual
niobium deposition and codeposition of niobium and aluminium with Al-Nb alloys
formation.
Electrodeposition of niobium from the chloroaluminate melt with added niobium
(V) oxide seems to start at around – 0.100 V vs. Al and at about – 0.200 V vs. Al
aluminium starts codepositing. During the codeposition Nb-Al alloys were formed.
Niobium deposition starting potential from the electrolyte with niobium added by
anodic dissolution starts at 0.100 V vs. Al, and aluminium codeposition starting
potential was at around – 0.025 V vs. Al, followed by Nb/Al alloy formation.
