Aquaculture waste and carbon dioxide (CO2) are a global concern. Sarcodia suiae cultivated in outdoor photobioreactors (PBRs) using shrimp aquaculture wastewater and CO2 from biogas demonstrates significant benefits. It boosted biomass by 18.72 % with nearly 100 % removal of COD, inorganic nitrogen (N), phosphorus (P), and 41–89 % organic N and P removal from AWW. Sarcodia aqueous extracts were biostimulants for promoting mung bean and rice seedling growth, and Sarcodia remnants/shrimp pond bottom sludge generated a biogas yield of 457.07 L/kg-VS methane (CH4)/day. Biogas provides renewable energy for the system’s needs. The solid residues after biogas fermentation serve as biofertilizers for enhancing rice yield by a 15 % increase up to 5.53 tons/ha/year. A Zero-Waste approach is successfully established using S. suiae as a model for recirculating aquaculture wastes to sequester 239.04 tons CO2/ha/year, capture N and sulfur (S), and produce renewable energy. and create biostimulants and biofertilizers.

猪肉瘤零废物估价方法:回收水产养殖废物和二氧化碳用于生物刺激剂、生物肥料和生物能源生产



水产养殖废物和二氧化碳 (CO2) 是一个全球关注的问题。在室外光生物反应器 (PBR) 中使用虾养殖废水和沼气中的 CO2 培养的猪肉瘤显示出显着的好处它使生物量提高了 18.72%,从 AWW 中去除了近 100% 的 COD、无机氮 (N)、磷 (P) 和 41-89% 的有机氮和磷。Sarcodia 水提取物是促进绿豆和水稻幼苗生长的生物刺激剂,Sarcodia 残留物/虾塘底部污泥产生的沼气产量为 457.07 L/kg-VS 甲烷 (CH4)/天。沼气为系统需求提供可再生能源。沼气发酵后的固体残留物用作生物肥料,可将水稻产量提高 15%,最高可达 5.53 吨/公顷/年。以猪链球菌为模型,成功建立了零废物方法,将水产养殖废物再循环,以封存 239.04 吨二氧化碳/公顷/年,捕获氮和硫 (S),并生产可再生能源。并创造生物刺激剂和生物肥料。
