Invasion of Tomato Roots and Reproduction of Meloidogyne incognita as Affected by Raw Sewage Sludge.
The antagonistic effects of raw sewage sludge on infection of tomato by Meloidogyne incognita were tested in greenhouse pot experiments. Sludge was mixed with the soil or added on its surface before and after inoculation of tomato plants with nematode eggs. Juvenile penetration was determined 1 and 10 days after inoculation, and 6 weeks later root systems were assessed for nematode reproduction...
bacteria of the genus azospirillum are well known as plant growth promoting rhizobacteria. the ability to synthesize phytohormones is considered one of the most important mechanisms to promote plant growth and is widely distributed among plant-associated rhizobacteria.the most important phytohormone produced by azospirillum is the auxin indole-3-acetic acid, with the l-tryptophan as the precurs...
Background: Probiotics are living organisms that are beneficial for human health. Lactobacillus species has been considered as probiotic bacteria due to their adjustment of human immune responses and therapeutic effects in inflammatory disorders. The aim of the present study was to evaluate the effects of Lactobacillus probiotic strains on toll-like receptors (TLR2 and TLR4) expression in HT29 ...
Aims Postural tachycardia syndrome (POTS), a common and debilitating cardiovascular disorder, is characterized by an exaggerated heart rate increase during orthostasis and a wide spectrum of adrenergic-related symptoms. To determine the aetiology of POTS, we examined a possible pathophysiological role for autoantibodies against α1-adrenergic (α1AR) and β1/2-adrenergic receptors (β1/2AR). Meth...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
Zinnia is a very attractive and beautiful ornamental plant due to the diversity of color and flowering period. The effect of cycocel and pot size was studied on growth and flowering of zinnia in a factorial experiment based on a randomized complete design with two factors: cycocel at 3 levels (0, 1000 and 2000 ppm) and pot size at 4 levels (10, 12, 14 and 16 cm) with 12 treatments and 3 replica...
abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
The susceptibility of coliform bacteria and bacterial pathogens to free chlorine residuals was determined before and after incubation with amoebae and ciliate protozoa. Viability of bacteria was quantified to determine their resistance to free chlorine residuals when ingested by laboratory strains of Acanthamoeba castellanii and Tetrahymena pyriformis. Cocultures of bacteria and protozoa were i...
Background and Objectives: Lactic acid bacteria are usually involved in the preparation of fermented foods and can produce different metabolites according to their strain type. The aim of this study was to evaluate the antimicrobial, antioxidant and aggregation activities of 10 different strains of Lactobacillus plantarum isolated from native fermented foods including Koozeh cheese, fermented o...
