求翻译：其它条件相同，在菌种富集过程中添加EDTA二钠可使H2产量增加到471.68mL，而在菌种富集之后再添加EDTA二钠仅可使H2产量提高到34.4ml。是什么意思？

Other conditions are the same in bacteria enrichment process to add edta disodium enable h2 production increased 471.68ml, add edta disodium in bacteria enrichment only enable the h2 yield increased to 34.4ml.

Other conditions are the same, the rich set of bacteria in the process of adding 2 EDTA H2 production can be increased to 471.68 to mL, and rich in bacteria after 2, and then add EDTA H can only yield 2 to 34.4 ml .

Other conditions are same, concentrates in the process in the mold mushroom spawn to increase the EDTA two sodium to be possible to make the H2 output to increase 471.68mL, but again concentrates after the mold mushroom spawn increases the EDTA two sodium only to be possible to make the H2 output to

Other things being equal, strains in the enrichment process adds disodium EDTA H2 production increased to 471.68mL, while in bacteria enrichment and then adding disodium EDTA is only H2 production increased to 34.4ml.
