Abstract The present hype in microalgae biotechnology has shown that the topic of photo‐bioreactors to be revisited with respect availability really large scale measured hectars footprint area, minimization cost, auxiliary energy demand as well maintenance and life span. This review gives an overview about designs basic limiting factors which include light distribution avoid saturation kinetics, mixing along gradient make use light/dark cycles, aeration mass transfer vertical or horizontal...

First test flights using blends with algae oil are already carried out and expectations by the aviation other industries high. On hand technical data about performance of cultivation systems, downstream processing, suitability as fuel still limited. The existing microalgae growing industry mainly produces for food feed market. Energy efficiency is so far scope but needs to be taken into account if product changes biofuel. CO 2 balances used estimate potential fulfil EU sustainability...

Microalgae can contribute to a balanced diet because of their composition. Beside numerous essential nutrients, carotenoids are in the focus for food applications. The bioavailability from photoautotrophic-cultivated Chlorella vulgaris (C. vulgaris) and Chlamydomonas reinhardtii reinhardtii) was compared. An vitro digestion model used investigate carotenoid bioaccessibility. Furthermore, effect sonication on bioaccessibility assessed. Lutein main both species. C. showed higher amounts lutein...

Abstract A promising new dimension in the field of biotechnology is use microorganisms for production inorganic nanoscale particles. The interest nanotechnology provoked by unique properties nanostructured materials and their potential fields application ranging from medicine to electronics. This review article presents a systematic overview capable producing nanoparticles, describes cellular mechanisms outlines cultivation conditions that turn this process into successful synthetic pathway.

The fact that microalgae perform very efficiently photosynthetic conversion of sunlight into chemical energy has moved them the focus regenerative fuel research. Especially, biogas generation via anaerobic digestion is economically attractive due to comparably simple apparative process technology and theoretical possibility converting entire algal biomass biogas/methane. In last 60 years, intensive research on production from revealed as a rather challenging substrate for its high cell wall...

Phaeodactylum tricornutum (P. tricornutum) comprise several lipophilic constituents with proposed anti-obesity and anti-diabetic properties. We investigated the effect of an ethanolic P. extract (PTE) on energy metabolism in obesity-prone mice fed a high fat diet (HFD). Six- to eight-week-old male C57BL/6J were switched HFD and, at same time, received orally placebo or PTE (100 mg 300 mg/kg body weight/day). Body weight, composition, food intake monitored. After 26 days, blood tissue samples...
