Experimental Results

These results present experimental findings on biohydrogen production using a custom-made stirred tank reactor in four configurations: a conventional continuously stirred tank reactor (CSTR), a traditional anaerobic moving bed biofilm reactor (AMBBR), an AMBBR with a custom-designed baffle system, and a modified AMBBR with recycling. Each configuration underwent duplicate experimental runs, summarising cumulative hydrogen gas volume, productivity, and yield. The modified AMBBR with recycling demonstrated the highest performance among the configurations. The results also encompass an analysis of the microbial community within each reactor configuration. All configurations exhibited diverse microbial communities, predominantly dominated by Clostridia, the key hydrogen producers.本研究结果呈现了采用定制搅拌釜式反应器开展的四种配置下的生物制氢实验发现：传统连续搅拌釜式反应器（CSTR）、传统厌氧移动床生物膜反应器（AMBBR）、搭载定制挡板系统的AMBBR，以及带循环回流的改进型AMBBR。每种配置均开展了平行重复实验，汇总了累计氢气产气量、产氢速率与产率。在所有配置中，带循环回流的改进型AMBBR表现最优。本研究结果还涵盖了各反应器配置内的微生物群落分析。所有反应器配置均拥有多样的微生物群落，且均以产氢关键菌群——梭菌纲（Clostridia）为主要优势类群。
