Biochemical Methane Potential (BMP) and Biogas Analysis of Phycocyanin-Extracted Residual Biomass

This dataset provides comprehensive insights into the Biochemical Methane Potential (BMP) and biogas composition of residual biomass obtained after phycocyanin extraction. The study evaluates the biogas recovery potential of the residual biomass using various substrate-to-inoculum (S/I) ratios. Experimental Details: Residual Biomass: Phycocyanin-extracted residual biomass from microalgae. Inoculum Source: Biomass valorisation company (Innolab, Belgium). Setup: 140 mL serum bottles filled with 50 mL inoculum, 70 mL demi water, and varying weights of dried biomass to achieve S/I ratios of 1, 2, 3, and 4 (standardised by grams of volatile solids, gVS). Total working volume: 120 mL. Incubation: 37 °C water bath for 21 days. Biogas Measurement: Biogas production was measured daily using a syringe. Biogas was collected in Tedlar bags and analysed using a gas analyser (Geotech–BIOGAS5000). Dataset Includes: Daily biogas production data for each S/I ratio. Biogas composition analysis results, including methane and carbon dioxide.本数据集提供了藻蓝蛋白（phycocyanin）提取后剩余微藻生物质的生化甲烷潜力（Biochemical Methane Potential，BMP）与沼气组分的全面分析数据。本研究针对不同底物-接种物比（substrate-to-inoculum ratio，S/I）的剩余生物质，评估其沼气回收潜力。 实验详情： 剩余生物质：来源于微藻的藻蓝蛋白提取残余生物质。 接种物来源：比利时Innolab生物质资源化企业。 实验装置： 采用140 mL血清瓶，内装50 mL接种物、70 mL去离子水（demi water），通过称取不同质量的干生物质，使底物与接种物的质量比以挥发性固体克数（grams of volatile solids，gVS）计分别为1、2、3、4。总工作容积为120 mL。 培养条件： 置于37 ℃水浴环境中培养21天。 沼气检测： 每日采用注射器测定沼气产量；将沼气收集于泰德拉袋（Tedlar bag）中，并使用Geotech–BIOGAS5000型气体分析仪开展组分分析。 数据集包含： 各S/I比对应的每日沼气产量数据，以及沼气组分分析结果（涵盖甲烷与二氧化碳含量）。
