Sampling Device-Dependence Of Prokaryotic Community Structure On Marine Particles: Higher Diversity Recovered By In Situ Pumps Than By Oceanographic Bottles, Viena Puigcorbe, Clara Ruiz-Gonzalez, Pere Masque´, Josep M. Gasol

Research outputs 2014 to 2021

Microbes associated with sinking marine particles play key roles in carbon sequestration in the ocean. The sampling of particle-attached microorganisms is often done with sediment traps or by filtration of water collected with oceanographic bottles, both involving a certain time lapse between collection and processing of samples that may result in changes in particle-attached microbial communities. Conversely, in situ water filtration through submersible pumps allows a faster storage of sampled particles, but it has rarely been used to study the associated microbial communities and has never been compared to other particle-sampling methods in terms of the recovery of particle microbial …
