| جلبک کلرلا کاربرد دارویی، صنعتی وغذایی دارد. به همین دلیل بالا بردن بیوماس ومتابولیت‌های آن ارزشمند است. هدف این پژوهش نیز به دست آوردن بهترین ماده یا ترکیب هورمونی برای افزایش بیوماس ومتابولیت‌هایارزشمند Chlorella sorokiniana بود. در این پژوهشجلبک C. sorokiniana در محیط کشت پایۀBold ((BBM اصلاح‌شدهکشت شد. به محیط‌ها نسبت‌های مختلف هورمونی نفتالن استیک اسید ((NAA، ایندول بوتیریک اسید ( (IBAوکینتین Kin) )، نیترات و فسفات و تیامین پیروفسفات افزوده شد. در تیمار با NAA (10 میلی‌گرم در لیتر) Kin+(یک میلی‌گرم در لیتر) وزن خشک، محتویات رنگیزه‌های فتوسنتزی و پروتئین نسبت به شاهد افزایش معنی‌داری یافت. این صفات در تیمار با IBA+Kin وتیامین پیروفسفات اختلاف معنی‌داری را با شاهد نشان نمی‌داد بالاترین افزایش معنی دار وزن خشک، محتویات رنگیزه‌های فتوسنتزی و پروتئین نسبت به شاهد در تیمار افزایش نیترات و فسفات مشاهده شد. | ||

| چکیده [English] | ||
| Chlorella has applications in medicine, industry and food. For this reason, increase of biomass and its metabolites is valuable. Aim of this study was to obtain the best substance or phytohormone combinations to increase biomass and metabolites contents of Chlorella sorokiniana. In this study, Chlorella sorokiniana was cultured in modified Bold Basal Medium (BBM). Different proportions of plant hormones, naphthalene acetic acid (NAA), indolebutyric acid (IBA) and kinetin (Kin), nitrate and phosphate and thiamine pyrophosphate were added to medium. There was significant rise in dry weight, photosynthetic pigments and protein contents in treatment NAA (10mg.L-1) + Kin (1mg.L-1) compared with control. In treatment of IBA+ Kin, and thiamine pyrophosphate no significant difference was observed in these parameters. The highest significant enhancement of dry weight, metabolites and protein contents were observed in medium supplemented with higher amount of nitrate and phosphate. | ||
