The use of alga biomass for biogas generation has been studied for over fifty years but until today, several distinct features, like inefficient degradation and low C/N ratios, limit the applicability of algal biomass for biogas production in larger scale. In this work we investigated a novel, one-stage combined cultivation/fermentation strategy including inherently progressing nitrogen starvat...
Research objective was to identify the specific features of distribution microelements (zink, manganese, lead, cadmium) in organs and tissues black-backed shad Alosa kessleri (Grimm, 1887) Dolginsky herring braschnikowii (Borodin, 1904) caught Caspian Sea. Accumulated fish concentrations exceeding maximum permissible limits, heavy metals pose a danger human health. Sampling carried out by stand...
For osteological studying of Paraschistura delvarii, thirty-three specimens of this species were collected from Gharah-aghaj river in Gulf basin (Fars Provance) by electro shocker. Fish were preserve 10% formaldehyde. Osteological studies were performed on all specimens following transportation to the laboratory samples were cleared and stained. The most important skeletal characteristics to di...
Invasive round goby Neogobius melanostomus and bighead goby Ponticola kessleri have successfully colonized freshwater and coastal habitats worldwide. The objective was to use stable isotope analyses to study the foraging and movement of both species at small spatial scales in the Upper Danube River, considering 861 samples from two different years, seasons and sides of the river in an area wher...
اواسط شهریور 1401 و در نزدیکی ساحل ماسهای رودخانۀ نکا شمال ایران، به روش تورزدن روی گلآذین بوتههای کاهوک (.Lactuca serriola L) میان تمشک وحشی (.Rubus idaeus انار (.Punica granatum L)، نمونهای جیرجیرک جمعآوری شد که بررسی توسط کلیدهای شناسایی شکلشناسی مقایسه با نمونههای از قبل تعیین نام شدۀ موزۀ حشرات هایک میرزایانس رکورد جدید جنس گونه را تایید کرد. این اولین گزارش گونۀ Arachnocephalus ves...
The current study proposes a simple monodimensional model to estimate the linear growth rate of photosynthetic microorganisms in flat-plate photobioreactors (FPPBRs) during batch cultivation. As a model microorganism, Chlorella kessleri was cultivated photoautotrophically in FPPBRs using light-emitting diodes (LEDs) as the light sources to provide unidirectional irradiation in the photobioreact...
A presumably full-length cDNA clone of the mitochondrial ATP/ADP translocator (AAT) of Chlorella kessleri has been isolated and sequenced. The expression of the AAT gene is highly increased in the presence of D-glucose (14 mM). At least nine more genes are activated when autotrophically grown Chlorella cells switch to heterotrophic growth. Among these is the HUP1 gene coding for the hexose tran...
