大气CO2浓度升高对繁茂膜海绵滤食海水细菌能力的影响
Influence of increasing atmospheric CO2concentration on the ability of the marine sponge Hymeniacidon perlevis to filter-feed bacteria in seawater
摘要
Abstract
The influence of carbon dioxide (CO2) concentration on the capability of Hymeniacidon perlevis fil-ter-feeding bacteria was studied by simulating an elevated atmospheric CO2concentration. In the simulated ecosys-tem, the capability of H. perlevis filter-feeding Escherichia coli AS 1.1017 and Vibrio splendidus was explored, respectively, in sterilized seawater under 387, 500, 750 and 1 000 μmol/mol. The results showed that the effi-ciency of H.perlevis filter-feeding bacteria was improved when the CO2concentration elevated from 387 μmol/mol to 500 μmol/mol;however,the capacity of H.perlevis filter-feeding bacteria was decreased when the CO2concen-tration elevated to 750 μmol/mol . This result indicates that the relatively high CO2concentration damages the fil-ter-feeding efficiency of H.perlevis,and the efficiency was lost when the CO2concentration elevated to 1000 μmol/mol. This study provides a scientific basis for predicting the effect of atmospheric CO2concentration on the coastal ecosystem.关键词
