Although significant advances in H2 photoproduction have recently been realized in fresh water algae (e.g. Chlamydomonas reinhardtii), relatively few studies have focused on H2 production and hydrogenase adaptations in marine or halophilic algae. Salt water organisms likely offer several advantages for biotechnological H2 production due to the global abundance of salt water, decreased H2 and O2...

The odor of four algae was investigated and compared to evaluate the potential these mimic shrimp aroma. Solid-phase microextraction followed by gas chromatography analysis coupled with sensory used for performance assessment. volatile organic compounds were determined in non-processed, raw samples (r), processed cooked (c) cooking water (w) two microalgae [ Nannochoropsis oceanica (NO) Tetrase...

Four species of microalgae were evaluated at different temperatures for their ability to remove ammonia from intensive marine fish/shrimp culture systems. Growth rates were highest on the first of three days of culturing for marine microalgae Nannochloropsis oculata, Isochrysis aff. galbana, Chaetoceros muelleri, and Tetraselmis chui. This rate was used to compare both the growth and the total ...

The optimization of copepod feeding protocol is paramount to improve culture productivity and maintain favorable water quality parameters overtime, as well saving operational costs by preventing the production unnecessary quantities microalgae. influence microalgal concentration on major related calanoid Bestiolina similis (Paracalanidae) was investigated in a series laboratory experiments. B. ...

Although it has been well established that different species of marine algae have different sensitivities to metals, our understanding of the physiological and biochemical basis for these differences is limited. This study investigated copper adsorption and internalisation in three algal species with differing sensitivities to copper. The diatom Phaeodactylum tricornutum was particularly sensit...

The green algal flagellate, Tetraselmis, is a key transition organism in the phylogeny of green algae. It has been proposed that the cell wall of Tetraselmis arose evolutionarily from the fusion of scales and that this event secondarily caused the alteration of some cytoplasmic processes such as mitotic and cytokinetic mechanisms. Ultrastructural and developmental studies of the cell wall were ...
