[ 1 ] - Investigation of optimal condition for Chlorella vulgaris microalgae growth

Due to its abundance and also flexibility of cultivation conditions, Chlorella vulgaris microalgae is one of the most ideal options available in order to production of microalgae based biodiesel. Since vulgaris cultivation for fuel production needs economic considerations to be taken, and in first place providing biomass and lipid production costs is important, wide researches have bee...

[ 2 ] - Wastewater Treatment by Azolla Filiculoides: A Study on Color, Odor, COD, Nitrate, and Phosphate Removal

The aquatic fern Azolla, a small-leaf floating plant that lives in symbiosis with a nitrogen fixing cyanobacteria (Anabaena), is an outstanding plant, thanks to its high biomass productivity along with its tremendous rate per unit area for nitrogen-fixation. The present study investigates the potential growth of Azolla in secondary effluents for removal of COD, phosphorus, and nitrogen. Resul...

[ 3 ] - Catalytic production of biodiesel from corn oil by metal-mixed oxides

The present study investigates the transesterification of corn oil with methanol over two oxides of MgO and ZnO at 65 ͦC and 1 atm. These two catalysts have been prepared via a conventional co-precipitation process. As for MgO, the corresponding mixed metal nitrate solution has been mixed and heated at the presence of urea. ZnO has also been synthesized by co-precipitation of metal acetate at th...

[ 6 ] - بررسی فرایندهای انعقاد الکتریکی و شیمیایی برای جداسازی میکروجلبک های آب شور

اقتصادی و تجاری شدن تولید سوخت زیستی از میکروجلبک‌ها نیازمند حل برخی مشکل ‌های پیش روی آن می ‌باشد. یکی از کلیدی ترین و پرهزینه ترین مرحله‌ های آن، جداسازی میکروجلبک از محیط کشت می ‌باشد.در این پژوهش ابتدا به بررسی این مشکل و ارایه روش‌ های گوناگون جداسازی زیست توده از محیط کشت پرداخته شد و سپس از بین روش‌ها به دلیل سادگی و قابلیت صنعتی شدن، روش انعقاد ـ فلوکولاسیون الکتریکی (...

[ 7 ] - An Environmental Friendly Process for Extraction of Active Constituents from Herbal Plants

Conventional methods for extraction of the active constituents from herbal plants, in addition to their high processing costs, are harmful to the environment owing to their time and energy consumption, uncontrollable parameters, use of toxic and dangerous solvents, loss of the extract, thermal instability, the contamination of the product with organic solvents and the loss of water-soluble comp...

[ 8 ] - The effects of glucose, nitrate, and pH on cultivation of Chlorella sp. Microalgae

BACKGROUND AND OBJECTIVES: Bioenergy is a phenomenon that has attracted humans’ attention for about a century. The desirable biological properties of chlorella sp.microalgae have turned it to one of the most ideal options for the production of biodiesel. However, the economic issues must be taken into account in its industrial scale production. The present study aims t...
