چکیده مقاله :
در این تحقیق تاثیر پیش تیمار ترکیبی زمان (24 و 96 ساعت) و pH (7 و 9) در شرایط محدودیت افراطی دی اکسید کربن (عدم هوادهی، عدم تلقیح دی اکسید کربن)، بر فاز تصاعدی رشد، محتوای رنگیزه ای به ازای سلول، جابجایی جذب کلروفیل، ساختار و عملکرد فیکوبیلی زوم، نسبت رنگیزه‌‌های مرکز واکنش و کمپلکس‌‌های جمع آوری کننده نور؛ و نسبت فتوسیستم یک به دو در سیانوباکتری استیگونماتال Fischerella sp.FS 18 بررسی گردید. نتایج نشان داد اعمال پیش تیمارها در هردو زمان 24 و 96 ساعت و هر دو شرایط خنثی و قلیایی، سبب حفظ فاز تصاعدی رشد شد. بر خلاف قله جذبی کلروفیل، رنگیزه‌‌های سلولی از الگوی ثابتی در رابطه با پیش تیمارها تبعیت نمی‌کردند. نقطه اصلی تاثیر پیش تیمارها، فیکوبیلی‌زوم بود. سیانوباکتری در بخش میله‌ای خود الگوی یکسانی را از نظر واکنش به پیش تیمارها نشان داد. فیکوسیانین به اندازه یک واحد و فیکواریترین تا سه واحد تحت تاثیر پیش تیمارها تغییر جذب نشان داد. بالاترین نسبت فتوسیستم یک به دو در شرایط بیست و چهار ساعت و محیط خنثی مشاهده شد. گذشت زمان این نسبت را کاهش داد و سبب ضعف در بهره‌وری انتقال انرژی در سیستم‌‌های فتوسنتزی گردید. تغییر در عملکرد فیکوبیلی زوم می‌تواند نوعی مکانیسم ترمیمی برای جبران این کاهش باشد.
In the present study, the effects of pretreatment of time (24 and 96 hours) and pH (7 and 9) at extremely limited carbon dioxide concentration were studied on the exponential growth phase, photosynthetic pigments per cell, absorption shift of chlorophyll, structure and function of phycobilisome, the ratio of light harvesting to reaction center pigment, and the ratio of photosystem 1 to photosystem 2 in stigonematalean cyanobacterium Fischerella sp.FS 18. Results showed that pretreatments kept the exponential growth phase at both 24 and 96 hours and also under pHs 7 and 9. Contrary to the absorption peak of chlorophyll, cellular pigments showed no stable pattern regarding pretreatments. Phycobilisomes were the main point of treatment affects. The pattern of the rode part of phycobilisomes was the same at pretreatment reactions. The shift of phycocyanin was about 1 and phycoerythrin about 3. The highest rate of photosystem 1 to photosystem 2 ratio was observed at 24 hours and under neutral condition. This changed by the time and led to decreased efficiency of energy transport in photosynthesis system. The change in the phycobilisome operation may be a compensation mechanism to mitigate the degree of such a decrease.
