Makeup Water Addition Can Affect the Growth of Scenedesmus dimorphus in Photobioreactors

چکیده

Makeup water constitutes a key component in the management of microalgal cultivation systems. However, effect makeup addition on growth remains largely unexplored. This study compared two deionized intervals (1 day and 4 days) for their Scenedesmus dimorphus (S. hereafter) 2000 mL Pyrex bottles under controlled conditions. Cell counts dry algal biomass (DAB) were measured to characterize rate. Water impacted cell but had little DAB. Adding every resulted higher rate (8.80 ± 1.46 × 105 cells mL−1 day−1; p = 0.22, though) an earlier occurrence peak count (day 9) than adding it days (6.95 1.68 day−1 12, respectively). It is speculated that loss over extended period following posed stress S. dimorphus. Surpassing count, continued grow DAB, resulting increased weight as response nutrient starvation. Optical density at 670 nm (OD670) was also measured. Its correlation with DAB found be affected by (R2 0.955 1 0.794 days), possibly due loss-induced change chlorophyll content. expected facilitate photobioreactor open pond

Scenedesmus dimorphus biofilm: Photoefficiency and biomass production under intermittent lighting

This study investigated the effect of intermittent lighting on the growth performances of a Scenedesmus dimorphus biofilm. Flashing light effect (FLE) is common in traditional suspended cultures of microalgae; yet, publications about this phenomenon, in the context of biofilm cultivation, are scarce. In this work we demonstrate that, thanks to intermittent illumination, it is possible for attac...

Growth and Morphological Changes in Scenedesmus dimorphus Induced by Substances Released from Grazers, Daphnia magna and Moina macrocopa

Some freshwater phytoplankton species are plastic in their morphology, physiological characteristics, genetic structure, and biochemical composition. These characteristics of planktonic algae vary considerably under different environmental conditions in aquatic ecosystems. Algae such as Staurastrum sometimes lose their spiny form, and large multi-f ilament ‘f lakes’ of Aphanizomenon grows as si...

اثر نانوذره اکسیدمس بر سیستم رنگدانه ای جلبک Scenedesmus dimorphus

مقدمه: نانومواد به دلیل اندازه‌ بسیار کوچک خواص متمایزی نسبت همان ماده در حالت توده‌ای دارند. اندازه‌ی نانویی باعث غالبیت بعضی خواص مربوط به اتم‌ در نانوذرات می‌شود. این ویژگی‌ها ممکن است اثراتی منفی بر فیتوپلانکتونها در پایه زنجیره‌ غذایی داشته باشد. در تحقیق حاضر اثر سمیت نانوذره اکسیدمس (CuO-NP) Scenedesmus dimorphus به روش OECD201 مورد بررسی قرار گرفت.مواد و روش‌ها:...

Toxicity of nanoZnO in Daphnia magna fed with ZnO containing Chlorella vulgaris and Scenedesmus dimorphus algae

Nano ZnO is currently used in the rubber, electronics, electrical appliances, enamel, cosmeticsand medical industry. Whereas most studies have used the ecological toxicity of nanoparticles, the toxic effects of nanoparticles in diet is not extensively explored. Because the algaeare at the base of the food chain, any change in their density, biomass and population, wouldaffect the food chain in ...
