When microalgae culture medium is recycled, ions (e.g. Na(+), K(+), Ca(2+)) that were not assimilated by the microalgae accumulate in the medium. Therefore, a growth medium (HAMGM) was developed that included ions that were more easily assimilated by Chlorella vulgaris, such as ammonium one (NH(4)(+)). Recycling performance was studied by carrying out 8-week continuous cultivation of C. vulgaris with recycled HAMGM medium. No loss of biomass productivity was observed compared to culture in a conventional medium, and accumulation of ions over time was negligible.
当微藻培养液被回收时，未被微藻吸收的离子（例如 Na(+)、K(+)、Ca(2+)）会在培养液中积累。因此，开发了一种生长培养基（HAMGM），其中包含更容易被普通小球藻吸收的离子，如铵离子（NH(4)(+)）。通过使用回收的 HAMGM 培养基对普通小球藻进行 8 周的连续培养来研究回收性能。与在传统培养基中的培养相比，生物量生产力没有损失，而且离子随时间的积累可以忽略不计。
