Edible Alginate-Lecithin Films Enriched with Different Coffee Bean Extracts: Formulation, Non-Cytotoxic, Anti-Inflammatory and Antimicrobial Properties.

The aim of this study was to analyze the functional properties of newly obtained films based on sodium alginate and lecithin with the addition of antioxidant-rich coffee extracts and to verify their potential as safe edible food packaging materials. In our study, we developed alginate-lecithin films enriched with green or roasted coffee bean extracts. The roasting process of coffee beans had a significant impact on the total phenolic content (TPC) in the studied extracts.

Assessment of the content of macronutrients and microbiological safety of dry dog foods.

In Europe, there are no legal regulations specifying maximum allowable limits for pathogenic bacteria or fungi and yeasts in dog food. For proximate composition, the European Pet Food Industry Federation (FEDIAF) nutritional guidelines provide minimum recommended levels for protein and fat only, not for other ingredients and no safe maximum levels. Therefore, the aim of this study was to evaluate the microbiological safety of 35 dry dog foods, taking into account the division into foods with grains as the main plant ingredient and those described as grain-free.

Singularity of the Spectrum for Smooth Area-Preserving Flows in Genus Two and Translation Surfaces Well Approximated by Cylinders.

We consider smooth flows preserving a smooth invariant measure, or, equivalently, locally Hamiltonian flows on compact orientable surfaces and show that, when the genus of the surface is two, almost every such locally Hamiltonian flow with two non-degenerate isomorphic saddles has singular spectrum. More in general, singularity of the spectrum holds for special flows over a full measure set of interval exchange transformations with a hyperelliptic permutation (of any number of exchanged intervals), under a roof with symmetric logarithmic singularities. The result is proved using a criterion for singularity based on tightness of Birkhoff sums with exponential tails decay.

Size distribution of microbial aerosols in overground and subterranean treatment chambers at health resorts.

Purpose: to perform comparative analyzes of the size distributions of bacteria and fungi in the air of overground therapy chambers in Szczawnica sanatorium and subterranean inhalation chambers in Bochnia Salt Mine health resort taking into account influence of the season and presence of pathogenic species.

Methods: bioaerosol samples were collected using 6-stage Andersen impactor. Bacterial and fungal aerosol concentrations and size distributions were calculated and isolated microorganisms were taxonomically identified based on their morphological, biochemical, and molecular features.

Assessment of microbiological and chemical properties in a municipal landfill area.

This study aimed at determining the environmental hazards for soils posed by a large municipal landfilll. The concentrations of heavy metals and Policyclic Aromatic Hydrocarbons, as well as microbial composition (i.e.

Bioaerosols of subterraneotherapy chambers at salt mine health resort.

Nowadays, an inhalation of naturally generated aerosols has again become a widely practiced method of balneological treatment of various respiratory diseases. The aim of this study was to characterize the microbial aerosol of subterraneotherapy chambers at the Bochnia Salt Mine Health Resort in southern Poland. The measurements were carried out using a 6-stage Andersen impactor over a period of 1 year in both indoor (i.

Assessment of relationship between fungal aerosol within a municipal dump and epiphytic mycoflora of crop plants.

A field study was performed to assess whether fungal aerosol of a municipal dump may impact on quantitative and qualitative characteristics of epiphytic mycoflora of crop plants cultivated in vicinity of the dump. Sampling sites were located at every side of the dump. Plant samples were collected from field bean, spring wheat and potato.

Microbial air quality at Szczawnica sanatorium, Poland.

Nowadays, sanatorium treatment is undergoing a renaissance; however, data on air quality in such premises are scarce. The aim of this study was to characterize microbial air quality at the Szczawnica sanatorium in Southern Poland. The bioaerosol measurements were carried out using a 6-stage Andersen impactor over a period of one year in 3 naturally ventilated sanatorium premises (where different curative treatments took place) and in outdoor air.

[Municipal landfill site in Krzyz near Tarnów as source of microbiological factors harmful to environment and human health].

The present study aimed to evaluate microbiological pollution of air with microorganisms belonging to different taxonomic and physiological groups, and to examine whether the effect of the municipal landfill site in Krzyz changes at various study sites located: in so called "zero zone" (operating landfill), at different distances from the landfill and in Tarnów. Microbiological studies of atmospheric air were carried out from May 1998 to April 2001. Measurements were taken at 10 study sites located at the operating municipal landfill site in Krzyz, inside and outside of its protection zone.
