Última A New Photobioreactor for Continuous Microalgal Production in Hatcheries Based on External-Loop Airlift and Swirling Flow ArchiMer Loubiere, K; Olivo, Erell; Bougaran, Gael; Pruvost, J; Robert, Rene; Legrand, J. This study deals with the scale of a new photobioreactor for continuous microalgal production in hatcheries. The combination of the state-of-art with the constraints inherent to hatcheries has turned the design into a closed, artificially illuminated and external-loop airlift configuration based on a succession of elementary modules, each one being composed of two transparent vertical interconnected columns. The liquid circulation is ensured pneumatically (air injections) with respect to a swirling motion (tangential inlets). A single module of the whole photobioreactor was built-up to scale its geometry (diameter and length) and to optimize its design (air sparger, tangential inlets). The volumetric productivities were predicted by modeling radiative... Tipo: Text Palavras-chave: Isochrysis affinis galbana; Swirling flow; Airlift; Hatchery; Continuous photobioreactor. Ano: 2009 URL: http://archimer.ifremer.fr/doc/2009/publication-5288.pdf Mass transfer efficiency of a vacuum airlift-Application to water recycling in aquaculture systems ArchiMer Barrut, Bertrand; Blancheton, Jean-paul; Champagne, Jean-yves; Grasmick, Alain. In aquaculture, oxygen transfer and carbon dioxide stripping are the first limiting factors to fish rearing intensification. In this study we measured the O-2 and CO2 mass transfer coefficient (K(L)a) for a vacuum airlift in fresh (<1% salinity) and sea water (35 parts per thousand salinity) recirculating aquaculture systems (RAS). The airlift was composed of two concentric tubes: an inner riser tube and an external downcomer tube and can be adjusted at three different heights: 2,4 or 6 m. Several types of air injectors were tested, delivering different sizes of bubble swarms depending on their porosity and functioning conditions (low or high injection pressure), with air flows varying from 0 to 80 L min(-1). Experiments were also carried out at... Tipo: Text Palavras-chave: Mass transfer; Airlift; Vacuum; Aquaculture; RAS; Aeration; Degasification; Salinity.

Tecnol. Aliment. Silva,Diego Aires da; Antonio,Regina Vasconcellos; Rossi,José Márcio; Pena,Rosinelson da Silva. Pseudomonas oleovorans were grown on sugary cassava extracts supplemented with andiroba oil for the synthesis of a mediumchain- length polyhydroxyalkanoate (PHA MCL). The concentration of total sugars in the extract was approximately: 40 g/L in culture 1, 15 g/L in cultures 2 and 3, and 10 g/L in culture 4. Supplementation with 1% andiroba oil and 0.2 g/L of (NH4)2HPO4 was performed 6.5 hours after growth in culture 3, and supplementation with the same amount of andiroba oil and 2.4 g/L of (NH4)2HPO4 was performed at the beginning of growth in culture 4. The synthesis resulted mainly in 3-hydroxy-decanoate and 3-hydroxy-dodecanoate units; 3-hydroxy-butyrate, 3-hydroxy-hexanoate; and 3-hydroxy-octanoate monomers were also produced but in smaller...

Ano: 2014 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0101-20612014000400014 Water delivery capacity of a vacuum airlift – Application to water recycling in aquaculture systems ArchiMer Barrut, Bertrand; Blancheton, Jean-paul; Champagne, Jean-yves; Grasmick, Alain. A study was undertaken to measure the water flow (Qw) delivered by a vacuum airlift designed for recirculating aquaculture systems (RAS) in fresh (<1‰ of salinity) and sea water (35‰ of salinity). The vacuum airlift consists of two concentric tubes connected at their top to a depression chamber. The water rises in the inner tube as a result of air being injected in its lower section and flows back through the external downcomer tube. The vacuum airlift was adjusted at three different lengths: 2, 4 or 6 m and water discharge could be lifted from 0 to 30 cm. Air flow rate (Qg) varied from 0 to 80 L min−1. Different types of air injectors were tested, delivering different bubble sizes (0.1–5 mm) depending on porosity and functioning at low or high...
