چکیده مقاله :
میکروجلبک‌ها گروه بزرگی از موجودات ساده می‌باشند که در صنایع دارویی، آرایشی، بهداشتی، غذایی و تولید بیودیزل نقش دارند. میزان رشد میکروجلبک‌ها تحت تاثیر شرایط محیط فیزیکی و شیمیایی محیط رشد قرار می گیرد. در مقیاس تجاری به منظور دستیابی به بالاترین میزان زیست توده و یا افزایش میزان تولید سوخت زیستی، استفاده از محیط‌های کشت با ترکیبات مناسب ضروری است. بنابراین در این پژوهش تاثیر مقادیر مختلف دما، شدت تابش نور،مدت تابش نور، شوری و اسیدیته بر تراکم سلولی، تولید زیست توده، تولید لیپید و بیودیزل میکروجلبک Desmodesmus بررسی شد. در این مطالعه بهترین دما برای افزایش تراکم سلولی جلبک دسمودسموس، دمای ۲۵ درجه سانتی‌گراد، شدت نور ۴۵۰۰ لوکس، 17 ساعت نوردهی، شوری برابر با ppm ۵ و pH ۸ به دست آمد. بیشترین میزان زیست توده تولیدی در شدت تابش نور ۳۰۰۰ لوکس،مدت تابش برابر با ۱۸ ساعت، شوری برابر با ppm ۵ و pH برابر با ۹ به دست آمد. بالاترین میزان تولید لیپید در دمای ۲۶ درجه سانتی گراد، شدت تابش نور برابر با ۴۲۰۰ لوکس، مدت تابش برابر با ۱۶ ساعت، شوری برابر با ppm ۱۲ و pH برابر با ۹ بود. بالاترین بیودیزل تولید شده در دمای ۲۶ درجه سانتی گراد، شدت تابش نور ۴۲۰۰ لوکس، مدت تابش نور برابر با ۱۶ ساعت، شوری برابر با ۱۱ و اسیدیته برابر با ۹ مشاهده گردید.
Microalgae are diverse group of simple organisms, which are incorporated in pharmaceutical, cosmic, nutritional and biodiesel productions. The amount of growth in microalgae is affected by physical and chemical conditions of growth environment. In commercial scale in order to achieve highest amount of biomass or biodiesel, it is necessary to use culture media with proper combination of materials. Therefore, in this study, effects of different values of temperature, light intensity, lighting period, saltiness and pH were tested by their effect on cell concentration, biomass, lipid and biodiesel production in desmodesmus microalgae. As a result, the best temperature for increase in cell concentration of microalgae was 25 degree of Celsius, light intensity of 4500 lux, light period of 17 hours, saltiness of 5 ppm and pH of 8. The highest amount of biomass was achieved in light intensity of 3000 lux, 18 hours of lighting, saltiness of 5 ppm and pH of 9. The highest amount of lipid was produced at temperature of 26, light intensity of 4200 lux, lighting period of 16 hours, saltiness of 12 and pH of 9. Finally, the highest amount of biodiesel was produced at temperature of 26, light intensity of 4200, lighting period of 16 hours, saltiness of 11 and pH of 9.
