Characterization of a novel strain of Tribonema minus demonstrating high biomass productivity in outdoor raceway ponds.

摘要: Abstract Photosynthetic algae represent a large, diverse bioresource potential. Yellow-green of the genus Tribonema are candidates for production biofuels and other bioproducts. We report on filamentous isolate from an outdoor raceway polyculture growing municipal reclaimed wastewater which we classified as T. minus. Over one year cultivation in 3.5 m2 ponds fed by wastewater, minus cultures were more productive than native algal polycultures, with annual average productivities 15.9 ± 0.3 13.4 0.4 g/m2/day, respectively. The biochemical composition biomass grown outdoors was constant year-round, 28.3 0.4% carbohydrates, 37.6 0.7% proteins, 6.1 0.3% fatty acids (measured methyl esters), up to 4.0% valuable omega-3 eicosapentaenoic acid, ash-free dry-weight basis. In summary, productive, easier harvest produced higher quality polycultures.
