Effect of removing bacteria and dissolved organic matter on DMS production in Nannochloropsis oceanica concentrates

The aim of this study was to determine the influence of bacteria and organic matter on the occurrence of dimethyl sulfide (DMS) over the shelf life of Nannochloropsis oceanica concentrates. Two concentrates were compared: Control treatment, composed of biomass collected by centrifugation and diluted to a cell density of 5 × 109 cells·mL−1, and a washed concentrate treatment, where the biomass underwent successive centrifugations to remove …
