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...

Cultivation of Scenedesmus dimorphus for C/N/P removal and lipid production

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:...

Characterization of biofilm-forming cyanobacteria for biomass and lipid production.

AIMS This work reports on one of the first attempts to use biofilm-forming cyanobacteria for biomass and lipid production. METHODS AND RESULTS Three isolates of filamentous cyanobacteria were obtained from biofilms at different Italian sites and characterized by a polyphasic approach, involving microscopic observations, ecology and genetic diversity (studying the 16S rRNA gene). The isolates ...

Influence of biomass production and detachment forces on biofilm structures in a biofilm airlift suspension reactor

The influence of process conditions (substrate loading rate and detachment force) on the structure of biofilms grown on basalt particles in a Biofilm Airlift Suspension (BAS) reactor was studied. The structure of the biofilms (density, surface shape, and thickness) and microbial characteristics (biomass yield) were investigated at substrate loading rates of 5, 10, 15, and 20 kg COD/m3. day with...
