Evaluation of various sulfides for enhanced photobiological H2 production by a dual-species co-culture system of Chlamydomonas reinhardtii and Thiomonas intermedia

摘要: Abstract Sulfides play an important role in the photobiological production of H2 from microalgae. Apart conventional sulfur deprivation strategy, addition sulfides is also found to promote hydrogen and biomass However, it still unclear that how different influence algae. Here, evaluation various for enhancing by co-cultivation Chlamydomonas reinhardtii Thiomonas intermedia was systematically investigated. Our results show can improve algae, sodium thiosulfate (Na2S2O3) displays best efficacy with a maximum photoproduction rate 255.52 μmol/mg Chl, which 5.9 times higher than pure algal culture. Notably, sustained be achieved intermittent supplement sulfides. Moreover, effects on physiological factors, such as starch accumulation, respiration hydrogenase activity algae were evaluated. This report provides fundamental information enhanced sustainable renewable using
