📄 Abstract（原文）
Aim: The study aimed to evaluate the carbon sequestration potential and phycocyanin recovery from industrial Spirulina biomass, to asses its feasibility as a sustainable biorefinery model for climate mitigation and value addition. Methodology:Monthly Spirulina biomass production and water-quality parameters were recorded for one year. Carbon content in the dry biomass was analyzed using a CHNS analyzer to estimate carbon sequestration. Phycocyanin yield and purity were determined monthly using the repeated freezethaw method to evaluate the economic feasibility of pigment extraction. Results: The Spirulina biomass showed carbon content ranging from 39.96% to 46.17%, resulting in an estimated annual CO sequestration of 176.04 2 tonnes. Biomass productivity exhibited moderate positive correlations with electrical conductivity and carbonate levels. The total annual phycocyanin yield was 2.606 tonnes, with monthly variation influenced by seasonal environmental factors. Interpretation: This study highlights the dual benefit of phycocyanin recovery and carbon sequestration in enhancing both environmental sustainability and economic returns from Spirulina cultivation. The biorefinery approach offers up to 41% additional revenue through pigment extraction and carbon credit monetization, supporting scalable, low-emission production models. These findings demonstrate practical utility for climate change mitigation and sustainable livelihood promotion in small- to medium-scale Spirulina enterprises.
