The aim of research was to verify scientifically variability selected parameters hygienic quality fresh (A), marinated (B-E) and grilled (G) poultry meat in relation its storage conditions. Marinated kept under various conditions (12 hours 48 at a temperature 0 4 °C 5 8 °C) until it heat-treated. Using microbiological physico-chemical methods, analysed fresh, marinated, as well state. During th...

BACKGROUND Escherichia coli is one of the best studied microorganisms and finds multiple applications especially as tool in the heterologous production of interesting proteins of other organisms. The heterologous expression of special surface (S-) layer proteins caused the formation of extremely long E. coli cells which leave transparent tubes when they divide into single E. coli cells. Such na...

The ability of some microorganisms to use lactic acid stereocopolymers and copolymers with glycolic acid as sole carbon and energy sources was studied under controlled or natural conditions. First, 14 filamentous fungal strains were tested in liquid cultures, adopting total lactic acid consumption, nitrogen source exhaustion, and maximal biomass production as selection criteria. Two strains of ...

At the Black Sea chemocline, oxygen- and sulfide-rich waters meet and form a niche for thiotrophic pelagic bacteria. Here we investigated an area of the Northwestern Black Sea off Crimea close to the shelf break, where the chemocline reaches the seafloor at around 150-170 m water depth, to assess whether thiotrophic bacteria are favored in this zone. Seafloor video transects were carried out wi...

Environmental pollution may be considered one of the main problems affecting world population. As effluents from textile industries are largest representatives sources water bodies due to disposal colored compounds in environment. Microorganisms capable thriving wastewater exhibit metabolic machinery synthesize a wide variety enzymes and/or secondary metabolites industrial interest. The present...

In the most cases of the practical fermentation processes with filamentous microorganisms, direct monitoring of the cell morphology and biomass distribution in the culture medium is not easy possible. Penicillium brevicompactum is one of the morphologically complex filamentous fungi with different structural forms. In this research, nutrient uptake and cell growth kinetics was investigated comp...

The degradation of the cross-linked cationic poly(amino acid)-glutaraldehyde (GA) hydrogels by two kinds of proteolytic enzymes, trypsin and Aspergillus Protease Type XXIII, and by seven species of soil filamentous fungi has been investigated using homo- and copolypeptides of lysine (Lys) and ornithine (Orn). Trypsin degraded the hydrogels prepared from poly(Lys) and copoly(Lys Orn)s but not po...

Leaves of oak trees are often infected by various pathogenic fungi. As it is difficult to remove such organisms quantitatively from the leaf surface and as it is often impossible to grow these organisms independently from their host, there are almost no molecular data available from these oak leaf specific pathogens. For the quantitative removal of the microorganisms a procedure was developed c...

Results Materials and Methods Four commercial dyes were used — Remazol® Black BA, Levafix® Blue Ca, Levafix® Yellow CA and Levafix® Red CA (Dystar). A standard anthraquinone dye, Remazol Brilliant Blue R (RBBR, Sigma) was also used. Dye stock solutions were added to solid or liquid decolorization media, up to 200 mg.L-1 final concentration. Rose Bengal Agar and Potato Dextrose Agar (both from D...
