Clostridium perfringens is the third leading cause of human foodborne bacterial disease and is the presumptive etiologic agent of necrotic enteritis among chickens. Treatment of poultry with antibiotics is becoming less acceptable. Endolysin enzymes are potential replacements for antibiotics. Many enzymes are added to animal feed during production and are subjected to high-heat stress during fe...

Osmotic effects on salt taste were studied by recording from the rat chorda tympani (CT) nerve and by measuring changes in cell volume of isolated rat fungiform taste receptor cells (TRCs). Mannitol, cellobiose, urea, or DMSO did not induce CT responses. However, the steady-state CT responses to 150 mM NaCl were significantly increased when the stimulus solutions also contained 300 mM mannitol ...

Abstract Populus nigra ‘Italica’ (Lombardy poplar) is a breeding cultivar of black poplar, widely used as street tree or windbreak, often exposed to salinity and limited water availability. roots can develop dual mycorrhizal associations with ectomycorrhizal (ECM) arbuscular (AM) fungi, non-mycorrhizal fungal endophytes (FE). The symbiotic fungi may alleviate the effects adverse environmental c...

This study was conducted in laboratory conditions to determine the response of some cool season turf grass species (Lolium perenne Caddieshack, Lolium multiflorum Jivet, Poa pratensis Evora, Festuca rubra Rassinante, arundinacea Starlet, ovina Ridu) different salt doses during germination period. In study, 8 NaCl doses, 0, 30, 60, 90, 120, 150, 180, 210 mM, were applied, rate (%), time plumula ...

Many secondary metabolites have insecticidal efficacy against pests and may be affected by abiotic stress. However, little is known of how plants may respond to such stress as pertains the growth and development of pests. The objective of this study was to determine if and how salt stress on cotton plants affects the population dynamics of aphids. The NaCl treatment (50 mM, 100 mM, 150 mM and 2...

Salt stress is an important abiotic stressor affecting crop growth and productivity. Of the 20 percent of the terrestrial earth's surface available as agricultural land, 50 percent is estimated by the United Nations Environment Program to be salinized to the level that crops growing on it will be salt-stressed. Increased soil salinity has profound effects on seed germination and germinating see...

Salt stress negatively affects many physiological processes in plants. Some of these effects may involve the oxidative damage of cellular components, which can be promoted by reactive oxygen species and prevented by antioxidants. The protective role of antioxidants was investigated in Lotus japonicus exposed to two salinization protocols: S1 (150 mM NaCl for 7 d) and S2 (50, 100 and 150 mM NaCl...

Soil salinity is an increasingly serious problem worldwide that reduces agricultural output potential. Selected beneficial soil bacteria can promote plant growth and augment tolerance to biotic and abiotic stresses. Bacillus subtilis strain GB03 has been shown to confer growth promotion and abiotic stress tolerance in the model plant Arabidopsis thaliana. Here we examined the effect of this ben...

A stopped flow rapid reaction apparatus capable of following changes of +/-0.02 pH unit in 0.1 ml of solution in less than 0.005 sec has been developed, utilizing a commercially available pH-sensitive glass electrode. Using this instrument, extracellular pH at 37 degrees C was followed from less than 0.025 sec to 300 sec after mixing equal volumes of the following CO(2)-free solutions: (A) norm...

the present study was conducted to evaluate the effect of ascorbic acid (asa) as an important antioxidant in alleviation of salt damage in oregano (origanum majorana l.). this research work was carried out at the research greenhouse of ferdowsi university of mashhad. foliar application of asa (0, 100, 200 mg/l) was carried out on the plants that were under salt stresses of 0, 50, 100 and 150 mm...
