“…& Although direct comparisons of biomass and EPS productivity in the two culture systems used here cannot be accurately evaluated, the use of biofilm reactors could represent a more economically viable option for biomass (and therefore polysaccharide) production at a pilot and subsequently at an industrial scale, considering the high costs associated with the harvesting of microplankton . & Biomass leftover from EPS production can also represent a valuable commodity that could be used for the extraction of other valuable by-products and the production of biofuels (Quintana et al 2011). …”

The molecular identification of seven biofilmforming cyanobacteria and the characterization of their exopolysaccharides were made and considered in terms of potential biotechnological applications. The studied strains were isolated from phototrophic biofilms taken from various Italian sites including a wastewater treatment plant, an eroded soil, and a brackish lagoon. The polysaccharides were characterized by use of ion exchange chromatography, circular dichroism, and cytochemical stains. All strains produced exopolysaccharides with differing ratios of hydrophobic and hydrophilic moieties depending on the species, the polysaccharide fraction (i.e., whether capsular or released), and the ambient conditions. It was shown that the anionic nature of the exopolysaccharides was due to the presence of carboxylic and sulfated groups and is likely the main characteristic with industrial applicability. Potential biotechnological applications are discussed.

“…because of their relatively higher lipid content (Scott et al 2010). Cyanobacteria -a microalgae prokaryote -is also gaining momentum in the biodiesel production arena with respect to its fast growth rate and lipid content (Quintana et al 2011). The aim of this study was to gain preliminary data on the potential of different microalgae -micro-phytoplankton, filamentous cyanobacteria and endosymbiotic dinoflagellates -found in the Mauritian waters in order to identify prospective biodiesel feedstocks.…”

HIGHLIGHTSTotal micro-phytoplankton count amounted to 6.59±1.27x10 5 cells L -1 which was dominated by diatoms (95.2%), followed by dinoflagellates (2.9%) and cyanobacteria (1.9%).  The cyanobacterial mats were identified as Leptolyngbya sp. and Nodularia harveyana, and the endosymbiotic dinoflagellates as the Symbiodinium clade C.  There were also differences recorded in the % lipid of the different microalgae (p<0.005) -among all, Symbiodinium clade C had the highest with (38.39±6.58%). The aim of this study was to assess the lipid content and the subsequent potential of different microalgae present in the Mauritian marine water to produce biodiesel. The share of micro-phytoplankton species in the water column was determined. The cyanobacterial mats and endosymbiotic dinoflagellates were characterised morphologically and genetically using RFLP. The samples were quantified gravimetrically and analysed using 1 H & 13 C NMR spectroscopy. Total micro-phytoplankton count amounted to 6.59±1.27x10 5 cells L -1 which was dominated by diatoms (95.2%), followed by dinoflagellates (2.9%) and cyanobacteria (1.9%). The cyanobacterial mats were identified as Leptolyngbya sp. and Nodularia harveyana, and the RFLP characterised the endosymbiotic dinoflagellates as the Symbiodinium clade C. The highest amount of lipid was recorded in the Symbiodinium clade C (38.39±6.58%).1 H and 13 C NMR analyses indicated the presence of acyl glycerols. An attempt to synthesise biodiesel by alkaline trans-esterification reaction was also performed and the presence of biodiesel was detected using the Fourier Transform Infrared Spectroscopy. The Infrared analysis yielded peaks at around 1738cm -1 and 1200cm -1 characteristic of the carbonyl and ether groups respectively, indicating the presence of biodiesel.

“…Cyanobacteria are genetically tractable prokaryotes which typically have higher photosynthetic and growth rates than higher plants. These microorganisms have basic nutritional requirements and can be grown using closed cultivation systems that do not compete with agriculture (Quintana et al, 2011). Importantly, several species of cyanobacteria live in hyper-arid deserts and produce metabolites that give them the ability to cope with both high UV radiation and severe desiccation (Fleming & Castenholz, 2007).…”
