| Abstract | This study set out to cultivate and
isolate hydrogen-oxidising bacteria (HOB) for microbial protein
production under a specific culture strategy with a particular focus on
assessing the influence of different environmental sources on enrichment
culture and strain diversity. Therefore, HOB were enriched from samples
collected from various freshwater lakes and streams, and novel strains
were subsequently isolated from these cultures. The enrichment procedure
revealed significant shifts in community compositions, which were
mainly driven by changes in the relative abundance of genera affiliated
to Pseudomonadota and Bacteroidota. Sample-specific variations were
observed in the communities of the inocula, reflecting distinct
community structures associated with distinct ecological functions. The
most common autotrophic HOB, Hydrogenophaga, proliferated in some of the cultures. However, several genera, such as Acinetobacter and Klebsiella
that have not been previously recognised with hydrogen-oxidation
characteristics, were also enriched, suggesting potential novel
contributors to HOB communities. |
