Flashing light effect on microalgae could significantly improve the light efficiency and biomass productivity of microalgae. In this paper, the baffles were introduced into the traditional flat plate photobioreactor so as to enhance the flashing light effect of microalgae. Making Chlorella sp. as the model microalgae, the effect of light intensity and inlet velocity on the biomass concentration...
Benzo[a]pyrene (BaP), a polycyclic aromatic hydrocarbon (PAH), is one of the major environmental pollutants that causes mutagenesis and cancer. BaP has been shown to accumulate in phytoplankton and zooplankton. We have studied the localization and aggregation of BaP in Chlorella sp., a microalga that is one of the primary producers in the food chain, using fluorescence confocal microscopy and f...
with increasing world populations, production of cost-effective and proper nourishment sources that can rapidly produce large amounts of nutritional value are needed. microalgae are publicly used as nutrient supplement. in this research a screening of endemic potent microalgae was carried out. chlorella , scenedesmus and spirulina sp. were isolated and purified and cultivated in liquid proper m...
Heavy metal pollution in aquatic ecosystems affects microalgae and zooplankton, alters the biomass and abundance of species, and promotes interspecies relationships to the predominance of less sensitive species. In this study, the effect of short-term stress of different concentrations of cadmium heavy metal on Chlorella sp. growth and some biochemical parameters have been investigated. Microal...
In this study, five Chlorella species (Chlorella vulgaris, Chlorella minutissima, Chlorella pyrenoidosa, Chlorella sp.1 and Chlorella sp.2) were grown in various nutrient medium including BG-11, BBM, Fog's medium and M4N medium for the evolution of biomass and lipid production potential. Among the tested medium, BG-11 was found most economical and efficient medium for all Chlorella species. To ...

جداسازی و تثبیت دی اکسید کربن به وسیله ریزجلبک ها افزایش غلظت دی اکسید کربن موجود در اتمسفر یکی از دلایل عمده گرم شدن کره زمین است. جریان گازهای خروجی از واحدهای صنعتی تقریباً شامل 3 تا 15% دی-اکسید کربن می باشد و ریزجلبک ها co2 را به عنوان منبع کربن طی فرایند فتوسنتز مصرف می کنند. در این تحقیق ریزجلبک chlorella sp جهت جداسازی co 2 و تولید زیست تولد در دو فتوبیوراکتور لوله ای و صفحه صاف کشت د...
Thenutrient medium used for the cultivation of microalgae adds more cost to its value-added product as well as the commercial scale application. Therefore in this study, focused feasibility of cattle urine as a cheap source of nutrients for microalgal growth, because, it contains various minerals and economical which may support the growth of microalgae and reduce the medium cost. To check this...
The isolation or engineering of algal cells synthesizing high levels of medium-chain fatty acids (MCFAs) is attractive to mitigate the high clouding point of longer chain fatty acids in algal based biodiesel. To develop a more informed understanding of MCFA synthesis in photosynthetic microorganisms, we isolated several algae from Great Salt Lake and screened this collection for MCFA accumulati...
