Cultivation of the filamentous chlorophyte Oedogonium in municipal wastewater effluent is known to improve water quality and yield lipid- and protein-rich biomass for industrial applications. Chlorophyte celluloses, whose molecular organization and physical traits differ from those of plants, represent yet another valuable extractive, and algal oxygen production is of economic value in wastewater treatment. Consequently, we explored cellulose and oxygen production from Oedogonium biomass batch-cultivated in treated secondary municipal wastewater effluent. We compared biomass, cellulose, and oxygen production outside and within an adjacent greenhouse, under differing dissolved CO2 and pH conditions, and during temperate-zone seasonal change from summer through fall. Overall production did not differ within or outside the greenhouse, but outside production was higher in summer and lower in fall as air temperatures declined. Batch cultivation offered advantages, but high levels of mixing and CO2 were essential to maintain neutral pH for optimal algal growth and oxygen production.

在市政废水流出物中进行温带区大麦ed的生产，以生产纤维素和氧气。

已知在城市废水中培养丝状绿藻类毛虫Oedogonium可以改善水质，并生产用于工业应用的富含脂质和蛋白质的生物质。叶绿素纤维素的分子组织和物理特性不同于植物，是另一种有价值的提取物，藻类氧气的生产在废水处理中具有经济价值。因此，我们探索了在处理过的市政二级废水中分批培养的八爪鱼生物质中的纤维素和氧气的生产。我们比较了在不同溶解的CO2和pH条件下以及从夏季到秋季的温带区域季节性变化期间，相邻温室内外温室中的生物量，纤维素和氧气产量。温室内外的整体产量没有差异，但是由于气温下降，夏季的外部产量较高，而秋季的外部产量较低。分批培养具有优势，但是高水平的混合和CO2对于维持中性pH以获得最佳的藻类生长和氧气生产至关重要。
