چکیده مقاله :
رشد، وضعیت رنگیزه‌ای، فعالیت تیتروژنازی، تغییرات هتروسیست و فتوسنتز سیانوباکتریوم غالب شالیزار Nostoc sp. JAH 109 در شرایط توام نور محدود (2 میکرومول کوانتا در مترمربع در ثانیه)، تغییرات اسیدیته (5،7،9 pHs) و تفاوت در شرایط محدودیت کربن معدنی محلول مورد بررسی قرار گرفته است. نتایج نشان می‌دهد که Nostoc sp. JAH 109 سویه‌ای قلیا دوست می‌باشد. بیشینه نرخ رشد ویژه در شرایط pH معادل 9 بدست می‌آید. اندازه فیکوبیلی زوم‌ها و نسبت PSII به PSI در شرایط 9 pH و عدم محدودیت DIC مشاهده می‌گردد. سویه در شرایط اسیدی قادر به رشد مطلوب نیست، اما شرایط خنثی همانند شرایط قلیایی احتمالاً سبب فعال شدن سیستم مربوط به مکانیسم تراکمی دی اکسید کربن می‌گردد. الگوی فعالیت نیتروژنازی کمابیش در روزهای نخست پس از تلقیح منظم و خطی است. بیشترین میزان تثبیت نیتروژن در شرایط 9 pH و عدم محدودیت DIC مشاهده می گردد. این امر در مورد الگوی نوسان فرکانس هتروسیست نیز صدق می‌نماید. بیشینه ظرفیت فتوسنتزی (Pmax) در واحد کلروفیل در شرایط DIC بدون محدودیت و به طور مشخص در شرایط قلیایی مشاهد گردیده است.
Growth, pigment compositions, nitrogenase activity, photosynthesis and heterosyct frequency fluctuations of dominant species Nostoc sp. JAH 109, isolated from rice field, were evaluated in combination of limited irradiance (2 uE.m-2.s-1), different pHs (5,7,9) and inorganic carbon availability. Nostoc sp. JAH 109, can be considered as an alkalophilic organism. Optimal growth rate were observed at pH 9. Size of phycobilisomes and relationship between photosystem II and photosystem I increased in pH 9 and DIC available condition. This strain could not grow well in acidic condition, but neutral and alkaline condition cause active carbon dioxide concentration mechanism system. The pattern of nitrogenase activity seems more or less regular and linear at the first days after inoculation both in neutral and alkaline conditions. With respect to nitrogenase activity, the highest rate was in pH 9 and DIC availability. This seems true for heterocyst frequency fluctuations too. The higher photosynthetic capacity (Pmax) per unit of chlorophyll was resulted in higher DIC concentration at alkaline condition.
