conclusions the findings of the current study indicate that at high concentrations of salt, the growth of bacteria reduces so that it stops at a concentration of 50 mg l-1 (5%). thus, the bacterium is halotolerant or halophilic. with an increase in phenol concentration, the growth rate increased. phenol toxicity appears at a concentration of 600 mg l-1. results the phenol concentration of 600 m...

HU is one of the most abundant proteins in bacterial chromosomes and participates in nucleoid compaction and gene regulation. We report experiments using DNA stretching that study the dependence of DNA condensation by HU on force, salt and HU concentration. Previous experiments at sub-physiological salt levels revealed that low concentrations of HU could compact DNA, whereas larger HU concentra...

Background & Aim:Satureja Isophylla L.  is a medicinal herb which belongs to the family Lamiacease. Salinity affects the growth, the quality and quantity of essential oils of medicinal plants. Chitosan is also considered as a biological elicitor which plays a role in improving production of secondary metabolites of medicinal herbs. The current project was cond...

Voluntary iodization of table salt prior to 1995 had a beneficial effect on the prevalence of goitre in some areas in South Africa. However, it was, due to limited availability and unequal access, unsuccessful in eradicating iodine deficiency and endemic goitre. Against this background the international focus on the eradication of IDD stimulated the introduction of mandatory iodization of table...
