coastal region of chah bahar port, sea of oman, was screened for the presence of bioluminescence bacteria for the first time. water samples were taken from surface and subsurface layers and immediately spread on nutrient seawater complete (swc) agar. luminous colonies were observed after an overnight incubation at 25°c. among twenty luminous isolates, four of them were selected for preliminary ...

We describe and illustrate herein one new genus and eighteen new eriophyoid mite species (Acari: Eriophyoidea) collected in northeast China.

(Aceraceae), Calepitrimerus flexuosus sp. nov. on Spiraea flexuosa Fisch. ex Cambess...

ticks are an important problem among zoonotic diseases. main veterinary species of hard ticks are: hyalomma sp. boophilus sp and rhipicephalus sp. among them hyalomma sp. have widespread distribution in iran and middle east. the best method to control hyalomma sp. is immunological one, by using antigens, which causes immunologic and physiologic reactions in host.bm86 is one of the best antigens...

to evaluate the inoculation effect of potassium releasing, phosphate solubilizing and nitrogen fixing bacteria on the fruit quality of tomato, an experiment based on randomized complete block design with 9 treatments and 3 replications has been conducted. in this experiment, tomato (super chief cv.) seedlings of the in the treasury cultivation with single and combined treatments of the potassiu...

phytoplankton communities play a significant role in the oceanic biological pump by forming the base of the trophic structure. increase in nutrients loading affects spatial and temporal distribution of phytoplankton. this study examined the phytoplankton community structure and ecological indices in relation to nutrients dynamics in both estuarine and oceanic areas of ramisi-vanga systems alon...

The biological phosphorus removal is a microbial process widely used for removing phosphorus fromwastewater to avoid eutrophication of water bodies. The study was aimed to screen the efficient phosphatereducing isolates and used to remove phosphate from synthetic wastewater using batch scale process. Thethree most efficient phosphate reducers were isolated and screened from eu...

introduction: dental pulp has neural fibers that produce neuropeptides like substance p (sp) and calcitonin gene-related peptide (cgrp). the inflammation of dental pulp can lead to an increase amount of sp and cgrp release, especially in symptomatic irreversible pulpitis. therefore, it can be assumed that neuropeptides have some role in the progression of inflammation of the dental pulp. the ai...

according to previous studies, the genus rheum in iran includes four species: r. turkestanicum janisch., r. persicum losinsk., r. ribes l. and r. khorasanicum baradaran & jafari. during the long-term study, based on field and many herbaria specimens, three new species including r. iranshahrii taheri & assadi sp. nov., r. kordestanicum taheri & assadi sp. nov. and r. austro-iranicum taheri & ass...
