The capability of the biosurfactant-producing strain Rhodococcus wratislawiensis BN38 to mineralize both aromatic and aliphatic xenobiotics was proved. During semicontinuous cultivation 11 g/l phenol was completely degraded within 22 cycles by Rhodococcus free cells. Immobilization in a cryogel matrix was performed for the first time to enhance the biodegradation at multiple use. A stable simultaneous hydrocarbon biodegradation was achieved until the total depletion of 20 g/l phenol and 20

for 15 minutes, and used as cell-free culture supernatant (CFCS) to check the percent decolorization.
Immobilization of A. terreus QMS-1 on carrier materials. Seventeen natural and synthetic carrier materials were selected for fungal immobilization based on their stability and cost effectiveness, including polyethene polymer, sand, gravels, natural loofah sponge, corn cob, used steel wool, orange peels, banana skins, nylon net, polyurethane foam (PUF), coconut bagasse, sugarcane bagasse, water

The aim of this study was to determine the usefulness of two fungal strains of Hypholoma fasciculare (L1 and L3) for effective decolorization of anthraquinone dye RBBR (remazol Brilliant Blue R). The main part of the work was concentrated on assessment of the influence of immobilization of biomass on the efficiency of RBBR removal. Zoo- and phytotoxicity of after process solutions were evaluated. Differences in the dye removal effectiveness between strains were observed. Decoloration of dye was

of this model is the economical profit of the logistics system ‘shipper – carrier – receiver’. The advantage of using the suggested model is the possibility of calculating invisible costs while evaluating alternative transport mode, including funds immobilization and cargo loss. The tools in the study are the methods of system analysis, mathematical modelling, regression analysis and expert evaluations. The acquired results can be used while justifying the mode choice and

ultrasound. Visualization of ultrasounds in a computer program is based on Fourier analysis, with a set level of sensitivity, which caused problem with determining the continuity of the ultrasound. Additionally, ultrasounds were listened in slow motion and, based on continuity of sound, referred to as one ultrasound.
The activity of the male and the female was scored during the low-frequency ultrasounds. Male behavior was analyzed in terms of immobilization, hole sniffing, exploration of the chamber

returning to the stable process conditions were also investigated. An increase of VOC concentration to 220-255 ppm did not significantly influence the deterioration of process efficiency. After the period of adaptation of microorganism to the process condition and immobilization of microflora on the packing material, the experimental set-up has been working reliably for 21 days.

oligotrophic aerobic denitrifying strain. A 2 ml CRI effluent water sample was smeared on OAD solid medium and incubated at 37°C for 24 h. The strain NF4 with high N removal ability in denitrification medium with NaNO3 as the sole N source was identified using the 16S rRNA gene sequencing.
Nitrogen removal experiments. The method by Wang et al. (2012) on sodium alginate immobilization was used to immobilize Delftia tsuruhatensis NF4. The free cells and immobilized cells of D. tsuruhatensis NF4 had the same
