Diatom volatile organic compound production is driven by diel metabolism and the cell cycle.

ABSTRACT:

Introduction

Volatile organic compounds (VOCs) are small, low-vapor-pressure molecules emitted from the surface ocean into the atmosphere. In the atmosphere, VOCs can change OH reactivity and condense onto particles to become cloud condensation nuclei. VOCs are produced by phytoplankton, but the conditions leading to VOC accumulation in the surface ocean are poorly understood.

Methods

In this study, VOC accumulation was measured in real time over a 12 h day-12 h night cycle in the model diatom Phaeodactylum tricornutum during exponential growth.

Results

Sixty-three m/z signals were produced in higher concentrations than in cell-free controls. All VOCs, except methanol, were continuously produced over 24 h. All VOCs accumulated to higher concentrations du
