Halotolerant streptomycetes isolated from soil at Taif region, Kingdom of Saudi Arabia II: RAPD-PCR analysis and salt tolerance-gene isolation
The genus Streptomyces is represented in nature by the largest number of species and varieties among the family Streptomycetaceae. This study aimed at extracting the DNA of four halotolerant Streptomyces strains followed by determination of DNA fingerprinting of them using a molecular tool. A trail to isolate salt tolerance gene(s) from their DNA was also aimed. RAPD-PCR technique was...

Genotoxic and cytotoxic effects of food flavor enhancer, monosodium glutamate (MSG) using Allium cepa assay
Genotoxic and cytotoxic effects of monosodium glutamate (MSG) used as flavor enhancer in foods was analyzed using the Allium cepa assay. Onion bulbs were grown at different concentrations (1, 3, 5 and 7 g/L) of MSG dissolved in distilled boiled water and also evaluated when dissolved in distilled water without boiling; a control group was also set up. The macroscopic (morphology and color of...

Arabidopsis and Musa cyclin D2 expressed in banana (cv. “Sukali Ndiiziâ€- AAB) enhances regeneration efficiency
Genetic transformation of banana is important because of its polyploidy, sterility and long generation time of most cultivars which limit conventional breeding. However, transformability and regeneration of transgenic lines remains low in bananas. This research reports on the potential of CycD2 genes to improve transformation and regeneration efficiency of banana (cv. “Sukali...

The potential of postharvest silicon dips to regulate phenolics in citrus peel as a method to mitigate chilling injury in lemons
This study investigated the ability of silicon dips to enhance the phenolic content in order to reduce the incidence of chilling injury in lemon fruit. Fruits were obtained from two farms and dipped in 0, 50, 150 and 250 mg L-1 solutions of K2SiO3 for 30 min and afterward, fruit were air dried and waxed. Thereafter, fruits were stored at -0.5°C and sampled after 28...

Effects of salinity on growth and organic solutes accumulation of Tabebuia aurea Manso (Benth and Hook)
Salinity is a problem that has increased annually and among the viable alternatives for the reintegration of saline areas to the productive system is the cultivation of tree species. This study aimed to evaluate the growth, dry matter distribution and organic solutes accumulation in Tabebuia aurea Manso (Benth and Hook) under salinity. The plants were grown in Hoagland solution...

Isoamylase profile of mung bean seedlings treated with high temperature and gibberellic acid
Heat stress is one of the common abiotic stresses and is the most harmful factor affecting the growth and productivity of any crop. Heat stress can reduce number of morphological and physiological properties of any living organism. Gibberellic acid (GA3), a plant growth hormone is also known for resistance of number of abiotic stresses like heat stress. Effect of high temperatures and...

Effects of crude humin and compost produced from selected waste on Zea mays growth, nutrient uptake and nutrient use efficiency
Waste from oil palm plantations, paddy fields, sawn timber and poultries are substantial. Inappropriate disposal of these wastes can cause environmental problems such as air and land pollutions. The objective of this study was to determine the effect of crude humin and compost produced from rice straw, rice husk, sawdust, and oil palm empty fruit bunch on growth, dry matter production, nutrient uptake and...

Bacteriological and physico-chemical analysis of drinking water in tobacco and food grain cultivating areas of Bangladesh
The growth in agricultural production has resulted in an increase in contaminants that pollute water ways and soil. The present study was done to analyze the bacteriological and physicochemical quality of drinking water in tobacco cultivating and food grain cultivating areas of Kushtia region in Bangladesh. The study was performed during the months of April to June, 2011. A total of 80...

Proximate composition of traditional local sorghum beer “dolo†manufactured in Ouagadougou
Dolo is a local beer manufactured from malted sorghum grains. It is the most commonly consumed alcoholic beverage in Burkina Faso (60% of population). Thirty (30) samples of dolo were collected from local markets in Ouagadougou and analyzed with respect to their proximate compositions and pH values using biochemical standard method. The average values of pH, dry matter and insoluble matter among...

Third ventricle neuropeptide-Y infusion effect on metabolic parameters under different energy levels in diets
The goal of this study was to determine whether neuropeptide-Y affects the mean plasma concentrations of metabolic parameters such as thyroxine (T4), triiodothyronine (T3), growth hormone (GH), insulin, glucagon, glucose, fatty acid and urea in the goats fed different energy content in diets. 16 goats were randomly divided into four groups. Animals in groups 1 and 2 were fed 100% energy content in diet and...

Optimization of peptide production by enzymatic hydrolysis of tuna dark muscle by-product using commercial proteases
A protein hydrolysate was prepared from proteins of tuna dark muscle by-product. The hydrolysis conditions (time, temperature, pH and enzyme concentration) using Alcalase and Neutrase were optimized by response surface methodology (RSM). The regression coefficient close to 1.0, observed during experimental and validation runs, indicated the validity of the model. The...
