| 英文摘要 | Non-photosynthetic chemoautotrophic microorganisms in deep-sea hydrothermal vent can obtain energy by oxidation reducing substances and synthesize CO2 into organic carbon, and the development and utilization of microbial re-sources in this environment for CO2 fixation under ordinary environmental conditions is of great significance to under-stand the carbon cycle and microbial carbon fixation in deep-sea hydrothermal vent. In this study, a set of spiral-stirred bioreactor (SSB) was developed to cultivate a group of non-photosynthetic chemoautotrophic CO2 assimilation micro-organisms (NPCAM), mainly Sphingomonadaceae (unclassified, the mean of which was 31.16 %), from deep-sea hydro -thermal vent sediments, which have the characteristics of halophilic, acid-base and heavy metal resistant. The maximum carbon fixation efficiency (calculated by CO2) was 6.209 mg center dot CO2/(L center dot h) after 96 h of incubation in the presence of mixed electron donors (MEDs, 0.46 % NaNO2, 0.50 % Na2S2O3 and 1.25 % Na2S, w/v), mixed inorganic carbon sources (CO2, Na2CO3 and NaHCO3) and aerobic conditions. The detection of NPCAM synthetic organic frac-tion in SSB system, the study of single bacteria culturability and carbon fixation efficiency, the analysis of CO2 fixation pathway and the development of coupled carbon fixation technology are the prospective works that need to be further developed. |
