EFFECTS OF SALT AND IRRADIANCE STRESS ON PHOTOSYNTHETIC PIGMENTS AND PROTEINS IN DUNALIELLA SALINA TEODORESCO
The aim of this study was to examine the effects of salinity and light intensity on the chlorophylls, ?-carotene and protein contents in Dunaliella salina Teod. The algae were grown in inorganic medium containing 0, 0.9, 1.8 (control), 2.6 and 3.5 M NaCl under three illumination regimens [4500 (control), 9000 and 11000 Lux]. The results showed that most electrophoresis protein bands were separa...
متن کاملPhotosynthetic carboxylating enzymes in marine phytoplankton’
Measurements of ribulose-1,5-bisphosphate carboxylase (RUBPCase) and phosphoenolpyruvate carboxylase (PEPCase) in several phytoplankton cultures and natural phytoplankton populations showed a positive correlation of photosynthesis with RUBPCase activity but not with PEPCase activity. Observed ratios of RUBPCase:PEPCase were high in log phase cultures when photosynthesis was maximal and low in s...
متن کاملtechnical and legal parameters for determination of river boundary,( case study haraz river)
چکیده با توسعه شهر نشینی و دخل و تصرف غیر مجاز در حریم رودخانه ها خسارات زیادی به رودخانه و محیط زیست اطراف آن وارده می شود. در حال حاضر بر اساس آئین نامه اصلاح شده بستر و حریم رودخانه ها، حریم کمی رودخانه که بلافاصله پس از بستر قرار می گیرد از 1 تا20 متر از منتهی الیه طرفین بستر رودخانه تعیین، که مقدار دقیق آن در هر بازه از رودخانه مشخص نیست. در کشورهای دیگر روشهای متفاوتی من جمله: درصد ریسک...
15 صفحه اولBiogeography of Photosynthetic Light-Harvesting Genes in Marine Phytoplankton
BACKGROUND Photosynthetic light-harvesting proteins are the mechanism by which energy enters the marine ecosystem. The dominant prokaryotic photoautotrophs are the cyanobacterial genera Prochlorococcus and Synechococcus that are defined by two distinct light-harvesting systems, chlorophyll-bound protein complexes or phycobilin-bound protein complexes, respectively. Here, we use the Global Ocean...
