Abstract The salinity stress is one of the most relevant abiotic stresses that affects the agricultural production. The present study was performed to study the improvement of the salt tolerance of tomato plants which is known for their susceptibility to salt stress. The present study aimed to assess to what extent strain Azospirillum brasilense (N040) and Saccharomyces cerevisiae improve the salt tolerance to tomato plants treated with different salt concentration. The inoculant strain A. brasilense (N040) was previously adapted to survive up to 7% NaCl in the basal media. A greenhouse experiment was conducted to evaluate the effect of this inoculation… More >

Abstract In the fed-batch cultivation of Saccharomyces cerevisiae, excessive glucose addition leads to increased ethanol accumulation, which will reduce the efficiency of glucose utilization and inhibit product synthesis. Insufficient glucose addition limits cell growth. To properly regulate glucose feed, a different evolution algorithm based on self-adaptive control strategy was proposed, consisting of three modules (PID, system identification and parameter optimization). Performance of the proposed and conventional PID controllers was validated and compared in simulated and experimental cultivations. In the simulation, cultivation with the self-adaptive control strategy had a more stable glucose feed rate and concentration, more stable ethanol concentration around the… More >

Abstract Vicilins (7S storage proteins) found in various legume seeds have been previously shown to interfere with the germination of spores or conidia of phytopathogenic fungi and inhibit yeast growth and glucose stimulated acidification of the medium by yeast cells. In the present work vicilins from cowpea (Vigna unguiculata) seeds were added to the growth medium of Saccharomyces cerevisiae cells and Fusarium oxysporum conidia. Helix pomatia lectin, wheat germ agglutinin and Ulex europaeus lectin were used to identify differences in the binding of the vicilins to the surface of cells of S. cerevisiae and F. oxysporum treated with this protein. After… More >

Abstract Current investigation has shown that human exposure to aflatoxins is not limited to the administration of contaminated cereals, but water is another possible source. This study was aimed to design easily applicable method to eliminate aflatoxin B2 (AFB2) from contaminated drinking water. Electrospinning has been used for preparation of probiotic-coated polyvinyl alcohol (PVA) and cellulose acetate (CA) nanofibers. Both of these hybrid nanofibers were studied by scanning electron microscopy (SEM) and Fourier-transformed infrared spectroscopy (FT-IR). SEM showed the proper coating of probiotic strains (Kluyveromyces lactis CBS 2359 and Saccharomyces cerevisiae ATCC 9763) on both nanofiber types. Different areas (1-5 cm²)… More >

Abstract Antifungal activity and mode of action of nine essential oils (EOs) against S. cerevisiae cells were examined. Antifungal effects of commercial lemon peel, orange peel, tea tree, turpentine, rosemary, peppermint, thyme, oregano and clove oils were determined through Minimum Inhibitory Concentration (MIC), Minimum Fungicidal Concentration (MFC) and inhibition zone measurements. The most effective oil was turpentine oil. Orange peel, thyme and oregano oils were also effective, according to MIC and MFC. Inhibition zone measurements, also revealed oregano, orange peel, thyme, turpentine and clove oils as most efficient ones. Later, membrane damage of yeast cells was studied by measuring the extracellular… More >

Abstract The expression of a gene is governed at various levels, from transcriptional to translational level. The translational control is widely used to regulate gene expression, especially when a rapid, local, and selective control over protein synthesis is required. The present review describes instructive examples of translational regulation in yeast, together with regulatory elements within mRNAs. The review also outlines the important contributions of mRNAbinding proteins that act in harmony with several translational elements to generate appropriate translational signals and responses. More >
