Both the fisheries and aquaculture sectors are facing strengthened regulations, with an emphasis on improving sustainable growth and environmental protection. The New Earth Observation Markets for Fisheries and Aquaculture (NEMA) project has established a number o...
An initiative has been taken to develop different solid, liquid, and gaseous biofuels as the alternative energy resources. The current research and technology based on the third generation biofuels derived from algal biomass have been considered as the best alternative bioresource that avoids the disadvantages of first and second generation biofuels. Algal biomass has been investigated for the ...
سیانوباکتریهای تولیدکننده هتروسیت گروه ویژهای از پروکاریوتهای فتوسنتزکننده هستند که قادرند نیتروژن اتمسفری را تثبیت کنند و در مزارع برنج به فراوانی یافت میشوند. هدف از این مطالعه خالصسازی و شناسایی سیانوباکتریهای مزارع برنج ناحیه کلات نادری از استان خراسان رضوی است. در راستای نیل به این هدف، فلور جلبکی 4 ایستگاه واقع در این ناحیه مورد بررسی قرار گرفت و در مجموع 30 تاکسون شناسایی شد. گونه...
Fresh water resources are depleting at a fast rate throughout the world affecting diverse aquatic flora and fauna. Algal responds to adverse changes in habitat which is reflected by their morphotaxonomical deformation occurrences of pollution tolerant taxa changed habitat. Based on findings more than five decades, it has been established that such labeled as bioindicator because tolerance. Taki...
The species diversity and changes in the structural dynamics of algal flora from alpine lake Nesamovyte has been studied for 100 years. During period investigations, 234 (245 infraspecific taxa) were revealed to cover more than 70% modern composition lake. biodiversity algae is characterized by an increase number widespread forms, a change baseline “montane” complex comparison beginning 20th ce...
