Phytoplankton cell lysis and aldehydes

Francois Ribalet and co-authors have published a new study in the journal PLoS ONE on phytoplankton cell lysis associated with chemical compounds release by diatoms. The study present data from four oceanographic cruises that took place during diatom blooms in the northern Adriatic Sea where concentrations of particulate and dissolved aldehydes produced by diatoms were monitored along with phytoplankton cell lysis. Cell lysis was positively correlated with both concentrations of particulate and dissolved aldehydes, supporting the hypothesis that these compounds are released by cell lysis. These results also suggest that aldehydes may help shape plankton community composition and function in the oceans.
