“…Filter presses have found wide application in industry due to the simple design, flexibility and capability to handle a wide range of slurries, and have been used to reduce the number of bacteria and yeast in wine (Brennan et al 1969;Richardson et al 2002). Although the equipment is relatively cheap, labour costs can be high and cake washing is not always effective (Brennan et al 1969;Richardson et al 2002).…”

“…Although the equipment is relatively cheap, labour costs can be high and cake washing is not always effective (Brennan et al 1969;Richardson et al 2002). A modified filter press with plastic diaphragms that inflate to remove the micro-algae from the filter membrane has been found to be effective in the filtration of Scenedesmus, but capital cost are approximately one third higher than conventional filter presses and pre-coating of membrane with starch was required to prevent clogging (Mohn 1988).…”

“…Rotary vacuum filters are a common filter design (Brennan et al 1969;Richardson et al 2002) and have been used to dewater organic sludge from anaerobic digestion (Bailey and Ollis 1977;Srinivas 2008). Coelastrum, a microalga that forms small colonies, can be filtered to a cake containing 18% dry weight solids without a filter pre-coat, but filtration rates fall rapidly and high energy inputs are required making this not recommended for micro-algal recovery (Mohn 1988).…”

“…It is one of the best-studied and most widely used cyanobacteria in biotechnology because of its fast growth in open ponds under alkaline conditions that largely exclude contaminating organisms (Ahmed et al, 2010b). Arthrospira platensis has enormous potential for applications in a variety of fields such as food, cosmetics, environmental improvement, aquaculture and in the future perhaps therapeutics (Rossi et al, 2005;Trabelsi et al, 2009). …”

Arthrospira platensis is a cyanobacterium known for its nutritional value and secondary metabolites. Extracellular polymeric substances (EPS) are an important trait of most cyanobacteria, including A. platensis. Here, we extracted and analysed different fractions of EPS from a locally isolated strain of A. platensis. Three different fractions of EPS were distinguished. These were EPS released into the medium (REPS), EPS loosely bound to the organism (LEPS) and EPS tightly bound to the organism (TEPS), which were extracted by different procedures. The LEPS fraction was smaller than the other two fractions. The EPS of A. platensis exhibited high diversity. Total protein and carbohydrate content was determined in each of these fractions. The largest amount of total carbohydrates and total proteins was in the TEPS fraction. Eight sugar moieties were detected and analysed in all EPS fractions using HPAE-PAD. Fructose, mannose and ribose were rare sugar residues in all fractions of EPS. With the exception of fructose, all sugars tested for were detected in TEPS. The amount of sugars detected was significantly higher in TEPS compared with the two other fractions, especially for galactose, xylose and glucose. The EPS were localized by confocal laser scanning microscopy (CLSM) after staining with different fluorescent dyes and it was found that A. platensis possessed a thick and smooth layer of EPS around the spiral trichomes.

Cheaper membrane materials for microalgae dewatering

A strategy to reduce costs in the microalgae dewatering process via membrane cross-flow filtration was investigated in this work. It consisted in assessing the possibilities of reduce membrane material cost. Several membrane materials, from commonly used in membrane technology (ceramic, polysulfone and polyacrylonitrile) to generally employed in packaging industry (acrylonitrile butadiene styrene, glycol-modified polyethylene terephthalate and polylactide) were tested. Where, last ones are considerably cheaper than common ones.Experiments carried out showed interesting results in terms of permeabilities for polysulfonePluronic® F127 blended membranes and polyacrylonitrile membranes, but with high related costs. Polylactide membranes had good price, mechanical properties results and biodegradability, but low permeability values. Glycol-modified polyethylene terephthalate *Corresponding author: +34.977.202.444, ctorras@irec.cat, carlestorrasfont@gmail.com 2 membranes showed attractive results in terms of costs and permeability, but poor mechanical properties. Finally, the polymer that gave the best results altogether was the acrylonitrile butadiene styrene that reached membrane permeabilities of 19 ± 0.9 L/h/m 2 /bar, really close to ceramic membranes performance (21 ± 2.9 L/h/m 2 /bar). Thus, a novel functionality was found for these not common polymers in water membrane filtration. Additionally, the biodegradable polylactide polymer introduces a new concept of cheap and environmental friendly membrane in this application.
