Abstract In this study, growth performance and lipid content of two microalgae species Neochloris oleoabundans and Chlorella vulgaris are monitored by using three different types of sludge waste feedstocks obtained from the water treatment plants located in Bedonia, Borgotaro and Fornovo (Montagna2000 Spa, Province of Parma, Italy). The sludge waste is optimized in order to achieve microalgal growth media and dispose of the sewage sludge produced at the wastewater treatment facilities. Both photoautotrophic and heterotrophic growth conditions are applied to the microalgal cultivations. The growth parameters of microalgae strains such as cell concentration, growth rate, optical density, cell biovolume, photosynthetic pigments and lipid contents are monitored. The amounts of total dried lipid biomass, obtained by the biological conversion of the wet sludge waste, are determined. Lipid production of microalgal cells grown in the medium optimized from sludge waste from the Fornovo site provides the highest amount of microalgal lipid content for N. oleoabundans and C. vulgaris photoautotrophic cultivations, while sludge waste from the Bedonia site provides for N. oleoabundans heterotrophic cultivation.

微藻培养生物废物转化和污水处理厂的整合

摘要 在这项研究中，使用从位于 Bedonia、Borgotaro 和 Fornovo 的水处理厂（Montagna2000 Spa，Parma 省）获得的三种不同类型的污泥废物原料，对两种微藻 Neochloris oleoabundans 和 Chlorella vulgaris 的生长性能和脂质含量进行了监测。 ， 意大利）。污泥废物经过优化，以获得微藻生长介质并处理废水处理设施产生的污水污泥。光自养和异养生长条件都适用于微藻培养。监测微藻菌株的生长参数，例如细胞浓度、生长速率、光密度、细胞生物量、光合色素和脂质含量。总干脂质生物量的量，通过生物转化获得的湿污泥废物，被确定。在从 Fornovo 站点的污泥废物优化的培养基中生长的微藻细胞的脂质生产为 N. oleoabundans 和 C. vulgaris 光能自养培养提供了最高的微藻脂质含量，而来自 Bedonia 站点的污泥废物提供了 N. oleoabundans 异养培养.
