| Summary: | Cultivation of specific microalgae is still difficult in an industrial setup
as contamination and balancing the economic cost are not always
possible. Understanding the ecology of cultivation of microalgae is
therefore necessary to implement stable production. The aim of the
study was to understand how different types of photobioreactors and
types of culture medium influenced the survival of a specific
microalgae inoculum, S. almeriensis. The bacterial and microalgae
community were studied using Illumina sequencing. Only the closed
configuration was able to maintain the inoculated species while all the
other systems developed a different eukaryotic community due to
contamination and the higher fitness of contaminants.
Photobioreactor configuration was more important than medium in
shaping the eukaryotes community, while the bacterial community
was influenced strongly by both. Results showed that even a well-
adapted strain is maintained only in the closed reactor while the open
reactors are colonized by a multispecies consortium. |
