The effect of biopolymer-water interaction on relaxation phenomena in blackcurrant pectin solutions.

Pectin is commonly used food additive. Depends on the source of the acquisition, its properties may vary significantly, therefore pectin obtained from different sources may be used for various purposes. Little information can be found about the properties of blackcurrant pectin.

The Effect of Feeding Chicken and Geese Broilers with Different Cereals on the Fatty Acids Profile in Meat.

The research was conducted on the effect of bird broilers fed with different hybrid rye doses on the fatty acids profile in muscle. The first experiment was performed on 3 geese broilers groups fed with hybrid rye, oats or hybrid rye and oats mix in proportion 1:1. No effect of the hybrid rye feeding of geese on the SFA level in meat was observed, but the MUFA level was significantly higher and PUFA level and n-6/n-3 PUFA ratio were significantly lower than in geese fed with oats.

Six new species of from hardwood trees in Poland.

(, ) is a well-supported monophyletic lineage within the , species of which occur in a diverse range of habitats including on forest trees, in the soil, associated with bark beetles and mites as well as on the fruiting bodies of some . Several species have also been reported as important human and animal pathogens. During surveys of insect- and wound-associated from hardwood trees in Poland, many isolates with affinity to were recovered.

A new genus and species of Hydrobiidae Stimpson, 1865 (Caenogastropoda, Truncatelloidea) from Peloponnese, Greece.

Minute caenogastropod brackish-water gastropods, formerly classified as , are important elements of the brackish-water fauna and were objects of intensive study for many years. Until now, five genera have been distinguished, most of them represented by a number of species, but rather indistinguishable without molecular data (cytochrome oxidase subunit I - COI). In the eastern Mediterranean region, they are still poorly studied.

Two new species of Ophiostomatales (Sordariomycetes) associated with the bark beetle from Poland.

Bark beetles belonging to the genus (Coleoptera, Curculionidae, Scolytinae) are known vectors of fungi, such as the pathogenic species involved in alpine fir () mortality. Associations between hardwood-infesting species and fungi in Europe have received very little research attention. Ectosymbiotic fungi residing in and (Ophiostomatales, Sordariomycetes, Ascomycota) were commonly detected in previous surveys of the -associated mycobiome in Poland.

Arabinoxylan-starch-protein interactions in specially modified rye dough during a simulated fermentation process.

The purpose of the work was to determine which processes occur during fermentation of rye dough beside progressive hydrolysis of biopolymers and production of gases, and also to determine which compounds are most responsible for them. The study was conducted with a specially modified dough containing starch, arabinoxylan preparations (non-modified, hydrolysed and cross-linked) and protein obtained from rye wholemeal. Despite the same consistency of the dough samples, their viscosity and values of rheological parameters depended on the amount of arabinoxylan preparations and their molecular weight.

Characterization of water and alkali extractable arabinoxylan from wheat and rye under standardized conditions.

Arabinoxylans (AXs) are an important component of wheat and rye dough. They bind water, contribute to the formation of viscous dough and improve the quality of bread. For the application of AX fractions in bread making process, it is useful to record a quality profile of wheat fractions compared to the quality profile of rye fractions under standardized conditions.

Application of cross-linked and hydrolyzed arabinoxylans in baking of model rye bread.

The role of water extractable arabinoxylan with varying molar mass and structure (cross-linked vs. hydrolyzed) in the structure formation of rye bread was examined using a model bread. Instead of the normal flour, the dough contained starch, arabinoxylan and protein, which were isolated from rye wholemeal.

Mapping genes governing flower architecture and pollen development in a double mutant population of carrot.

A linkage map of carrot (Daucus carota L.) was developed in order to study reproductive traits. The F2 mapping population derived from an initial cross between a yellow leaf (yel) chlorophyll mutant and a compressed lamina (cola) mutant with unique flower defects of the sporophytic parts of male and female organs.

Conversion of a diversity arrays technology marker differentiating wild and cultivated carrots to a co-dominant cleaved amplified polymorphic site marker.

Cultivated carrot and its wild ancestor co-occur in most temperate regions of the world and can easily hybridize. The genetic basis of the process of domestication in carrot is not well understood. Recent results of an investigation on genetic diversity structure of cultivated and wild carrot and signatures for domestication using Diversity Arrays Technology (DArT) allowed identification of polymorphisms differentiating wild and cultivated accessions.

Rye flour enriched with arabinoxylans in rye bread making.

The aim of the study was to investigate physical and chemical properties of preparations of water soluble arabinoxylans (arabinoxylan-enriched flour) obtained by industrial method and their derivatives (obtained by hydrolysis and cross-linking of aranbinoxylans), as well as their impact on baking properties of rye flours. Additionally, these results were compared with highly purified arabinoxylans prepared by laboratory method and well characterized in the literature. Flour enriched with arabinoxylans was obtained by industrial method involving air separation of flour particles.

Independent, non-IGF-I mediated, GH action on estradiol secretion by prehierarchical ovarian follicles in chicken. In vitro study.

Information concerning the role of growth hormone (GH) in the local regulation of ovarian activity in birds is limited. Therefore, the aim of the present study was to determine whether in the domestic hen GH influences in vitro estradiol secretion by prehierarchical ovarian follicles. Moreover, the interaction between GH and IGF-I on estradiol secretion was examined.
