This study evaluated anaerobic digestibility and biogas production potential of microalgal biomass and food waste. Biochemical Methane Potential (BMP) assays were conducted to determine the biogas generation potential of microalgal biomass and food waste both separately and together. Results indicated that several algal species in the collected samples are among the major harmful algal bloom (HAB) taxa found in freshwaters in North America. Bio‐methane yields for mono‐digestion of microalgal biomass and food waste were found to be 131–188 and 430–542 ml of bio‐methane per gram of volatile solids (ml CH4/g VS), respectively; while bio‐methane yield for co‐digestion of microalgal biomass and food waste was 426–505 ml CH4/g VS. Co‐digestion of microalgal biomass and food waste resulted in up to 12.3% increase in methane production relative to mono‐digestion of these substrates.

有害藻华和食物残渣作为生物甲烷的增值

这项研究评估了微藻生物质和食物垃圾的厌氧消化率和沼气生产潜力。进行了生化甲烷潜力(BMP)分析,分别确定了微藻生物质和食物垃圾的沼气生成潜力。结果表明,收集到的样品中有几种藻类是北美淡水中发现的主要有害藻华(HAB)类群之一。单消化微藻生物质和食物垃圾的生物甲烷产量分别为每克挥发性固体131–188和430–542 ml生物甲烷(ml CH 4 / g VS)。而同时消化微藻类生物质和食物垃圾的生物甲烷产量为426–505 ml CH 4/ gVS。与这些底物的单消化相比,微藻生物量和食物垃圾的共消化导致甲烷产量最多增加12.3%。
