Abstract Fructilactobacillus (F.) sanfranciscensis is a key bacterium in traditional (type 1) sourdough fermentations. It typically occurs combination with the yeast Kazachstania (K.) humilis or generalist Saccharomyces (S.) cerevisiae . Previous studies revealed intra-species diversity competitiveness dominance sourdoughs of F. , as well preferences for life without specific yeast. In this stu...

Probiotics are live microorganisms which when administered in adequate amounts confer a health benefit on the host. The concept of individual microorganisms influencing the makeup of T cell subsets via interactions with intestinal dendritic cells (DCs) appears to constitute the foundation for immunoregulatory effects of probiotics, and several studies have reported probiotic strains resulting i...

anti-microbial effects of the lactic acid bacteria have been studied and proved in various investigations. this investigation aimed to study the anti-yeast effect of two isolated lactic acid bacteria species from “chal” (a product from yogurt) as biological preservatives in doogh. to do so, anti-yeast activity of l. brevis and e. faecium against saccharomyces cerevisiae, kluyveromyces. marxianu...

Aneuploid genomes, characterized by unbalanced chromosome stoichiometry (karyotype), are associated with cancer malignancy and drug resistance of pathogenic fungi. The phenotypic diversity resulting from karyotypic diversity endows the cell population with superior adaptability. We show here, using a combination of experimental data and a general stochastic model, that the degree of phenotypic ...

the aim of this study was to determine the effect of yeast culture (saccharomyces cerevisiae sc 47) addition in the diet of dairy cows on their rumen fermentation and milk production. animals received a diet tmr based on good maize silage with a higher dry matter content (14 kg), 14 kg of lucerne-grass haylage, 5 kg of crushed ears of maize, 5 kg of beet pulp silage, 3 kg of crimped wheat, 2 kg...

steady state and dynamic fermentations of baker's yeast in molasses based media were analyzed in a laboratory scale bioreactor. sugar and biomass balances together with the monod biokinetics were used to develop the process model. parameters of the model were obtained using collected experimental data. model predicted open loop responses to step changes in feed concentration as well as dilution...

the objective of this study was to investigate fungal flora of the hair coat of domestic golden hamsterswith and without skin lesions. sixty hamsters were examined in the small animal teaching hospitalof the faculty of veterinary medicine, ferdowsi university of mashhad, and mashhad, iran. asteriletoothbrush was used for sample collection, from the entire body of the hamsters, all skin lesions ...

interferon is a protein secreted by eucaryotic cells following stimulation by viruses, bacteria, and many other immunogenes. recent medical studies indicate that interferons have effective role in the treatment of virus infections, immunodeficiency and certain types of cancer such as hairy cell leukaemia (hcl). the aim of the present study is to apply yeast strain for secreting human ifnα2b fol...
