Heterotrophic vs autotrophic production of microalgae: Bringing some light into the everlasting cost controversy
نویسندگان
چکیده
Heterotrophic or autotrophic? This is the continuous question industry faces when microalgae production endeavor. Surprisingly, nowadays specialists have not reached a consensus on which most economical option. The current work analyses costs for heterotrophic and autotrophic cultivation of at an industrial scale. results in cost 4.00 €·kg −1 dry weight as centrifuged paste. within range costs, but still above some photobioreactors. study also identifies limitations technology studies effect overcoming these. Once achieved, advances process could result reduced to 1.08 . Autotrophic seems competitive with production. It time leap forward scale achieve critical reduction cost. • A techno-economic assessment microalgal fermenters reveals costs. Advances achieving comparison shows similar auto-

Coupled nitrification–denitrification in autotrophic and heterotrophic estuarine sediments: On the influence of benthic microalgae
Field data obtained from 18 European estuaries using the isotope pairing technique were analyzed for trends in relationship between activity of benthic microalgae and coupled nitrification–denitrification. Kruskal–Wallis tests and analyses of covariance performed on the field dataset showed strong statistical evidence for the hypothesis that sediments colonized by microalgae whose activity exce...
متن کاملHeterotrophic denitrification vs. autotrophic anammox – quantifying collateral effects on the oceanic carbon cycle
The conversion of fixed nitrogen to N2 in suboxic waters is estimated to contribute roughly a third to total oceanic losses of fixed nitrogen and is hence understood to be of major importance to global oceanic production and, therefore, to the role of the ocean as a sink of atmospheric CO2. At present heterotrophic denitrification and autotrophic anammox are considered the dominant sinks of fix...

عصر روشنگری زمان شکل گیری ایده های مدرن تربیتی- آموزشی بود اما تاکید بیش از اندازه ی دوشاخه مهم فلسفی زمان یعنی عقل گرایی و حس گرایی بر دقت و وضوح، انسان عصر روشنگری را نسبت به دیگر تواناییهایش نابینا کرده و موجب به وجود آمدن افرادی تک بعدی شد که افتخارعقلانیتشان، تاکید شان بر تجربه فردی، به مبارزه طلبیدن منطق نیاکانشان وافسون زدایی شان از دنیا وتمام آنچه با حواس پنجگانه قابل درک نبوده و یا در ...
